The scientific publications of the National Museum consist of two series—Proceedings and Bulletins. The Proceedings, the first volume of which was issued in 1878, are intended primarily as a medium for the publication of original papers based on the collections of the National Museum, setting forth newly acquired facts in biology, anthropology, and geology derived there- from, or containing descriptions of new forms and revisions of limited groups. A volume is issued annually or oftener for distribution to libraries and scientific establishments, and, in view of the importance of the more prompt dissemination of new facts, a limited edition of each paper is printed in pamphlet form in advance. The dates at which these separate papers are published are recorded in the table of contents of the volume. The present volume is the fifty-first of this series. The Bulletin, publication of which was begun in 1875, is a series of more elaborate papers, issued separately, and, like the Proceedings, based chiefly on the collections of the National Museum. A quarto form of the Bulletin, known as the “Special Bulletin,” has been adopted in a few instances in which a larger page was deemed indispensable. Since 1902 the volumes of the series known as “‘Contributions from the National Herbarium,” and containing papers relating to the botanical collections of the Museum, have been published as Bulletins.

By Harrison G. Dyar, Custodian of Lepidoptera, United States National Museum. This is the fifth paper describing new species of Lepidoptera from Mexico. The Museum is indebted, as before, to Messrs. Roberto Miller and William Schaus for the material, also to Mr. B. Preston Clark for many fine things from a fresh region, and for one species to Mr. W. D. Kearfott. The present paper comprises 111 new species, 3 new subspecies, 7 new genera, reference to the synonymy of one previously known species and one synoptic table. Superfamily PAPILIONOIDEA. Family RIODINIDAE. Genus CARIA Hiibner. CARIA RABATTA, new species.

Phaegoptera rhoda Drucr, Ann. Mag. Nat. Hist., ser. 6, vol. 3, 1894, p. 173. Hemihyalea fuscescens RotuscHitp, Nov. Zool., vol. 16, 1909, p. 277. I identify this form by the descriptions of Druce and Hampson, since the figure in the Biologia Centrali-Americana (pl. 74, fig. 17) is apparently misleading and indistinguishable from daraba Druce, except for the brown thorax, which varies. True rhoda (=fuscescens Rothschild) is distinguishable from daraba by being gray-brown, without any pure ocher, which appears at the bases of the wings and in the bands of daraba, even of the more hyaline variations. The determinations in the collection before me are much mixed. HEMIHYALEA RHODA HIDALGONIS, new subspecies. Differs from rhoda in having the pale bands slightly marked on both costa and imner margin, faintly traceable across wing. In rhoda the bands are occasionally marked on the costa but not on the inner margin. Type.—Male, No. 18832, U.S.N.M.; Guerrero Mill, Hidalgo, Mexico, 9,000 feet (Mann and Skewes, gift of B.

The lingula gradually in- creases in size toward the posterior part and terminates with a rounded margin. The ovipositor (fig. 6, No. 9) is well developed and its two superior processes are a little longer than the inferior and lateral ones and are greatly attenuated. The lateral processes (fig. 6, No. 10) are finely crenulate. Male.—Length of the body, including the wings, 1.49 mm.; without the wings, 1.30 mm. Length of the antennae 0.78 mm.

SUBFAMILY ALEYRODINAE—QUAINTANCE &€ BAKER. 867 The dorsum is provided with four long sublateral bristles, two of which are situated upon the posterior part of the head and the other two upon the second abdominal segment. The margin of the body is very finely crenulate and. is provided with 16 bristles on each side and arranged as can be seen in figure 8. In the anterior submarginal part at the side of the first bristle there exists another bristle a little shorter than the adjoining one. The operculum is a little wider than it is long, and a little shorter than the lingula. The antennae (fig. 9, No. 1) are composed of the three joints, the first of which is short and the second a little longer; the third is thin and about five or six times as long as the second, and ends in a short bristle which might also be considered as a rudimentary fourth joint. The third joint is also provided near the apex with a small external spur to the angle upon which there is attached a very short bristle. Corresponding to this part of the antennae we have not been able to distinguish a division, in contradistinc- tion to that observed by Tullberg? and by Tragirdh? in the larvae of other Aleurodes. The legs (fig. 9, No. 2) are short, scarcely reaching, if spread out, the margin of the body, with all the joints distinct.

The tarsus is provided with an external apical bristle which is longer than the tarsus itself. The pretarsus is short, slender, and widened at the extremity. The larva of the first stage after it has attached itself begins to secrete white wax ail along the margin of its body (fig. 10, No. 1), around the dorsal bristles, and in the space between the anterior dorsal bristles. Around the body the marginal wax forms a fringe haying a width of 0.042 mm. around the dorsal bristles; internally it forms a kind of sheath, and between the dorsal bristles a kind of small plate (“lamin- netta’’).

The second-stage larva (fig. 10, No. 2) measures in length from 0.48 to 0.57 mm. and in width from 0.39 to 0.45 mm., and in the shape of its body comprising that of the legs is similar to the fourth stage of the larva which is described below. Around the margin of its body it has a fringe of wax formed of slender ribbon-like points whose length is 0.084 mm. and whose width is 0.009 mm. These at their apex are less separated from one another, while at the proximal part each of them is in contact with the one preceding and with the one following.

(AFTER SILVESTRI.) first stage in color, in size, in the form of the antennae and of the legs, and by the absence of the four dorsal bristles. The larva of the third stage is similar to that of the second and of the fourth, and presents the following dimensions: Length from 0.75 to 0.93 mm., width from 0.67 to 0.81 mm. Larva, fourth stage.—(fig. 10, No. 3.) The body is greatly de- pressed, almost laminate. Its length somewhat exceeds its width. The dorsum is black, provided with two tufted oblique transverse lines formed of white wax upon the marginal part of the cephalo- thorax some distance behind the level of the compound eyes and one narrow longitudinal line also consisting of white wax upon the median posterior part of the body behind the operculum. Around the margin there is found a fringe of wax like that found on the larvae of the second and third stages; but in this larva of the fourth stage this fringe is more or less broken up, and during the winter for the most part is lost entirely. The color of the venter (fig. 10, No. 4) is dark green in the central portion and black in the marginal portion, with a narrow lateral waxy area at a level with the base of the second pair of legs. This area close to this same pair of legs bifurcates and its branches join the two stigmata. Another area composed of wax exists in the pos- terior part of the body.

The width of the female varies from 1.48 to 1.52 mm. and of the male from 1.04 to 1.18 mm. Length of the antennae 0.325 mm.; of the legs 0.143 mm. The upper part of the body is divided by a furrow into a marginal zone and a central zone. The former shows no trace of division into segments and is a little more than a third as wide as one-half of the width of the whole body. It is variously striated in the proximal part, transversely striated in the distal part, and its margin is minutely lobed, each lobe corresponding to the mouth of the wax-producing gland across which issues a marginal thread of wax. This zone, examined under a high magnifying power, shows also a circular row of small and very short cilia near the base and some small pores which are quite sparse. The central zone is variously rugose; it shows distinotly the seg- mental impressions which can be seen accurately reproduced in figure 10, No. 3. The compound eyes are dorsal; they are situated some distance behind the anterior margin of the body and are represented on the surface each by a cornea. The antennae (fig. 9, No. 3 A) are entirely ventral, inserted at the side of the beak, scarcely in front of the first pair of legs. They are directly under the same in the rear and join a little on the outside at the level of the posterior margin of the base of the second pair of legs. They appear to be formed of a single joint (at least none can be seen distinctly); they are a little attenuated from the base to the apex and quite irregularly annulated. The apex terminates in a point a little curved, almost unguiform. The legs (fig. 9, Nos. 3 and 4) are very short, formed of a long and rather wide base which is prolonged into a short subtriangular appendix, truncate at the extremity and provided with a concave membranous disk which constitutes a kind of pulvillus. The anterior legs are distinctly in front, the middle and the hind legs are in the rear. The operculum is subtriangular; at its base it isa little longer than it is wide, with the apex slightly rounded and covering the whole of the lingula. ALEUROLOBUS PHILIPPINENSIS, new species. Plate 44, figs. 1-20. This species has been received from Manila, Philippine Islands, on several occasions; 1. e., June 3, 1904, on cultivated shade tree from Prof. C. H. Tyler Townsend; July 4, 1905, another lot, presumably of this same material, was received from Prof. T. D. A. Cockerell, who suggested that this was the first aleyrodid recorded from the Philippines. In May, 1910, we received from Mr. George Compere 36399°—Proc.N.M.vol.51—16——24 370 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 51. an abundant sending of this species taken at Manila on an unknown tree, and finally the same insect was received June 21, 1912, from D. B. Mackie, Manila, Philippine Islands, on Murraya exotica. The type lot is that forwarded by Mr. Compere. Eqg.—Size 0.165 by 0.096 mm.; color yellowish; without reticu- lations, stalk attached at larger end (fig. 1). Larva, first instar (fig. 2).—Size 0.165 by 0.258 mm.; shape elliptical; color, by transmitted light, light brown. Margin with usually 17 pairs of fine hairs situated on tubercles, of which the first and third caudal pairs, as well as the third cephalic pair, are longer than the others. Dorsal area with three pairs of stout short spines: One pair near the cephalic extremity between the eye spots, one pair at about the middle of the case and one pair cephalad of the vasiform orifice. Vasiform orifice (fig. 3) broad, triangular, with the anterior margin straight; operculum not half the length of the orifice, leaving the setose lingula exposed; size of orifice 0.027 by 0.024 mm. Antennae (fig. 20) composed apparently of four segments, the proxi- mal irregular and large. The others narrow, cylindric, with the distal one very acute and placed at an angle from the others. Larva, second instar (fig. 4).—Size 0.357 by 0.27 mm.; shape elliptical; color by transmitted light brown; margin with a series of about 15 pairs of spines, which are thick, short, and spear shaped (fig. 8). The caudal margin has a pair of rather long spine-like hairs The margin itself (fig. 7) is all around divided into a number of areas by irregular divisions extending a slight distance mesad; dorsal area with three pairs of spines similar to those present in the first instar, and also with a series of minute subdorsal pores, as well as a few other scattered ones. The area around vasiform orifice slightly indicated in this instar. Orifice itself (fig. 5) somewhat triangular, measuring 0.065 by 0.039 mm. Operculum similar in shape and extending a little over two-thirds the distance to the caudal extremity of the orifice. The inner membrane of the orifice below the operculum and lingula appears sculptured, with reticulate, circular, or irregular markings. Lingula (fig. 6) narrow; not swollen at the tip, part of which is seen below the operculum and which is setose and armed with a pair of rather long spine-like hairs. Pupa case (fig. 9).—Size 1.088 by 0.788 mm.; shape ellip- tical; color very dark brown by transmitted light, with the sutures separating the abdominal segments and a line marking off the mar- ginal fluted area lighter. Eye spots transparent, with their broadest part caudad. Dorsum of case completely covered with layer of wax, though the body segments are evident. From the submarginal area arises a short square-trimmed fringe of wax of same color as on dorsum, which extends out over margin of case. From marginal wax tubes arises a rather light fringe all around of grayish wax fila- — No. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 371 ments. Dorsum covered with a large number of very minute pores, which show as transparent dots. There is a pair of setae on the second abdominal segment and a pair cephalolaterad of the vasiform orifice. Some of the pore-like spots on the other part of the dorsum may also be the seats of minute setae, but if so we are unable to observe them owing to the dark coloration of the case. The vasiform orifice (fig. 10) is triangular in outline, with the cephalic margin almost straight; the operculum is similar in shape and almost entirely fills the orifice, obscuring all but the tip of the lingula. This last is setose and armed with two spines. The caudal inner membrane of the orifice is sculptured, and this sculpturing is visible below the lingula; surrounding the vasiform orifice is a differentiated area consisting of a rounded portion directly cephalad of the orifice, from which two arms extend caudad, one on each side of the orifice, forming a caudal channel (fig. 10). The legs (fig. 11) are dis- tinctly visible on the under surface of the case. Each is short, thick, and armed with a pad-like structure on the distal extremity. The antennae (fig. 13) are subcylindric, composed apparently of three segments, imbricated, and armed on the distal extremity with a nar- row finger-like process, and a distal spine. The margin of case (fig. 12) bears a series of fairly even crenulations. These are not prom- inent, and the submarginal area is marked by a series of lines extend- ing mesad, which gives it somewhat of a fluted appearance. On each of these sections a light spot may be observed near the margin, which spot seems to be the opening of a pore beneath. Scattered over the submarginal area there are a number of minute transparent spots similar to those on the dorsal area and on some of these small setae are located; on others, however, we are unable to find any. Adult female.—Length from vertex to tip of ovipositor about 0.960 mm.; color yellowish, shaded with dusky. Eyes dark brown, con- stricted in the middle. Antennae (fig. 19) of seven segments; II subpyriform, 0.045 mm. long, and usually armed with three stout spines; III subcylindric, 0.114 mm. long, imbricated, and armed with a few faint transverse sensoria, and near the distal extremity there is a circular fringed sensorium with a central process; IV subcylindrie, 0.024 mm. long; V similar, 0.033 mm. long; VI similar, 0.036 mm. long; VII subcylindric, tapering distally, armed at about the distal third with a number of minute circular frmged sensoria, and the distal extremity tipped with a spime. Forewing (fig. 15) about 0.95 by 0.38 mm.: radial sector curved, cubitus long, and fairly distinct; wings marked with rusty red, which forms two broken transverse bands, a distal spot over the tip of the radial sector, and a broken proximal one over the cubitus; margin beaded and bearig hairs. Hind wing with only one faint red spot in about the middle, below the vein. Vasiform orifice (fig. 16) broadly cordate, with the cephalic margin 372 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 51. straight; the operculum is rectangular, transverse, about half fillmg the orifice; lingula elongate, rounded, and slightly swollen at the tip; both operculum and lingula setose. Adult male.—Length from vertex to tip of genitalia about 0.95 mm.; color similar to that of the female. Antennae (fig. 18) of seven segments. In the specimens at hand these segments are difficult to discover, but in all of them VII seems to be extremely long, much longer than that of the female. Segment II subpyriform, 0.045 mm. long and armed with prominent spines; III subcylindric, 0.084 mm. long, imbricated and armed with several faint, transverse sensoria and a distal frmged sensorium with a central process. Segments IV, V, and VI each about 0.012 mm. long, almost globose on account of their shortness. Segment VII tapering distally, 0.18 mm. long, armed with a number of minute transverse sensoria, and tipped with a spine. Forewing with markings similar to those of the female, length about 0.89 mm., width about 0.37 mm.; hind wing about 0.72 mm. long, with a red spot similar to that of the female. Hind tibiae 0.24 mm. long; hind tarsus, proximal segment 0.066 mm., distal 0.06 mm. Foot (fig. 17) with an acute central paronychium, which is armed near its basal portion with a rather prominent spine. Claspers (fig. 14) 0.12 mm. long and 0.066 mm. broad at the base, tapering, with distinctly curved tips and each armed on its inner margin with a few spines; penis bulbous at the base, not as long as the claspers, and upceurved.

Rutherford at Peradeniya, Ceylon, represent this species. The first was taken on Harpullia pendula, July 7, 1913, the second on an unknown host, July 25, 1913, and the third on Harpullia, September 7, 1913. The species is easily sepa- rated from all others in the genus by the row of prominent spines on the submarginal area of the pupa case. Pupa case (fig. 1).—Size, 1.2 by 0.96 mm.; shape broadly ellip- tical, in this respect resembling taonabaec; color black, under the microscope dark brown, with the suture separating the dorsal disk and submarginal area, the eyespots, and the bases of the spines trans- parent yellowish. Dorsum with the abdominal segments distinctly marked and with a broad rachis-structure on the median area quite similar to that found in solitarius. The dorsal disk is armed with four pairs of rather long spines, three of which pairs are on the thorax and one pair on the abdomen, The submarginal area (fig. 3) * No. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 373 MPR OEE ee ron ee eee is broad and marked with a series of suture-like lines extending mesad, which lines are puckered about the base of each spine. These spines are prominent, extending beyond the margin of the case, are yellow in color, and are situated in the middle of the submarginal area, forming a row on each side of usually eight spines. Just within the margin the submarginal area shows a band composed of minute, closely placed, pore-like structures, and mesad of these there is a series of larger paired pores (fig. 6). The vasiform orifice (fig. 2) is usual for the genus, but it and the operculum are quite acute caudad. The arms of the trilobed area extending caudad from the orifice are relatively short and are swollen near the caudal margin of the case to include a pore-like structure on each side. The central tooth of the caudal pore is a distinct piece and appears as if mosaic, The channel leading from the pore to the caudal portion of the orifice is corrugated. The thoracic pore (fig. 4) ends in a trilobed structure, suggesting that of solitarius. It is not, however, so distinctly sepa- rated from the submarginal area. The margin (fig. 3) is armed with very flattened divisions which can scarcely be called teeth. Adult.—Unknown. Described from pupa cases in balsam mounts. Type.—Cat. No. 19128, U.S.N.M. ALEUROLOBUS SIMULUS (Peal). Plate 46, figs. 1-14. Aleurodes simula Prat, Journ. Asiatic Soc. Bengal, vol. 72, pt. 2, 1908, No. 3, p. 81. We have not seen this species and it is with some hesitation that we include it here. From the description and figures it seems to be fairly closely related to flavus which undoubtedly falls within this group. It should be noted, however, that the wing as given for simulus is unmarked, a condition not met with in any of the other species of this genus of which the adults are known, and the antenna of the male is nearly twice as long as that of the female. Egg.—Size, 0.2 mm. by 0.09 mm. Color, light yellow when first laid, afterwards turning brown. Peduncle about one-fourth length of egg. Examined while still within the body of the female the eggs are light yellow. The peduncle is curved. inwards and pressed against the egg. Color of peduncle pink; basal end of egg fairly dark yellow. Larva first stage.—Size, 0.25 mm, by 0.15 mm. Shape elliptical. Color, semitransparent yellow; two yellow pig- ment patches in center of abdominal region. There are a series of 34 long hairs right around margin. The four hairs furthest cephalad are grouped in two pairs placed some distance apart.

Abdominal segments distinct. Antennae and legs present. The artist has drawn the vasiform orifice as seen by him through the transparent body. Larva second stage.-—Size, 0.45 mm. by 0.32 mm, Shape, elliptical; color, yellow. Two yellow pigment patches in center of abdominal region. Two curved hairs caudad on margin. Vasiform orifice as in the pupa case, but the orifice is situated quite close to the margin. Abdominal segments distinct. yes maroon. A marginal fringe of stout, cylindrical, waxy filaments which are placed quite close together. Larva third stage.—Size, 0.7 mm. by 0.5 mm. Shape elliptical; margin at thorax angled shghtly outwards. Dorsum almost flat. Color yellow. Two setae caudad, and two setae placed caudolaterally on margin. A marginal fringe of stout, cylindrical wax filaments. Eyes maroon. Abdominal segments dis- tinct. Dorsum granular near margin. Margin broad, faintly de- marcated mesad, and deeply striated radially. There is a distinct yellow band extending from the posterior extremity of the vasiform orifice caudad to margin. There are faint indications of the two radial thoracic bands so conspicuous in the pupa. They end, as also does the band extending caudad to margin, in five separate brown horizontal pores which secrete a small quantity of brown wax. Dorsum covered with a large number of extremely minute circular pores. Larva fourth stage-—Size, 1.25 mm. by 1 mm. Similar to pupa case except in size; it is also flatter. Puparium.—Size, 1.86 mm. by 1.52 mm. Shape oval; anteriorly the thoracic margins angled outwards, giving the anterior end a somewhat square appearance. Color bright yellow. Dorsum at first somewhat flat, later turning fairly convex. Three ridges on dorsum, two radiating from thorax to cephalo- thoracic margins, and one from the posterior end of the vasiform orifice caudad to margin. These ridges are dark yellow, blotched with gray. They end marginally in five stout, distinct, brown pores, which produce a small quantity of brown fluffy wax.

There are also a series of submarginal pores, which produce finer and longer wax filaments. They are also spaced some distance apart. There are two small slender setae on cephalic, and two similar but smaller setae on lateral margins. The surface of dorsum and especially of the margin covered with a very great number of extremely minute circular pores, which tend to form de- tached groups. These pores are also present over the radial patches, but the grouping does not differ from the rest of the margin, the pores not being arranged in any sort of pattern. The margin of the pupa case turns quite white a short time before the adult emerges. Vasiform orifice conical, apex pointing caudad, Anterior margin flat. Lateral margins sloping inwards; the sloping surface with six ridges on each side. Operculum rhomboidal; the posterior margin somewhat incurved. The operculum extends to about or a little beyond the center of the vasiform orifice. Surface setose, color light brown. Lingula two-jointed, lower joint short, stout. Upper joint club-shaped. The lingula extends for one-third its length beyond operculum; the surface setose, color brown. Two long hairs spring from near the tip of the lingula and extend for some distance beyond the vasiform orifice. Pupa extracted from puparium. Head fairly broad, color yellow; the ocelli lighter in color. Thorax rather dark yellow, abdomen light yellow. Eyes dark maroon. Unfolded wings dark gray. Legs almost transparent, well formed, setose. Sides of abdomen flattened and spread out. Abdominal segments fairly distinct, but the vasiform orifice can not be made out. Antennae not noticeable in the specimen examined. When the adult emerges from the pupa case the dorsum splits up not only from the cephalic margin to thorax and across the thorax, but also right round the inner edge of the margin so that in empty pupal cases the anterior portion of the dorsum is usually missing. I have observed no parasites on this species. Adult female.—Length, 1.9 mm.; wing, size 1.9 mm. by 0.85 mm. Body light yellow; antennae and legs semitransparent white. Tip of mentum gray. A lateral gray stripe on each side of the first segment of the abdomen, and dorsally a rather broad diagonal gray patch on each side of the same segment. Dorsally each abdominal segment dark gray nearly the entire width of the body. An oval eray plate situated on the dorsal surface of the last segment of the abdomen. It incloses the vasiform orifice. Ventrally the abdomen covered with fine short hairs. Body and legs covered with white meal. Eyes reniform, almost divided; color dark maroon. Wings immaculate.

Joint 1, short, flat; jomt 2, subpyriform, twice length of joint 1; joint 3, fairly long, one and a half times length of joint 2; joint 4, short, less than half the length of joint 3; joint 5, long, almost equal to all the other joints together; joimts 6 and 7 equal, together about equal to joints 3 and 4. The antennae are heavily ringed, and it is extremely difficult to make out the joints. The under surface of the abdomen covered with a large quantity of white fluff. This species occurs in great abundance on the Simul tree (Bombyx malabaricum) in Caleutta. The leaves are thickly covered with the insect. They become yellow and spotted wherever an insect is attached and are ultimately killed. Superficially the insect some- what resembles A. ewgeniae Maskell. There are the same radiating dorsal patches and the dorsum is similarly striated. They differ, however, in the shape of the pupa case and the shape of the vasiform orifice. A. simula has a slight marginal fringe and there are four setae on the margin. The radiating dorsal patches are quite different in the two insects. In A. simula these patches are not formed by closely apposed pores, but are yellow bands striated with gray. The thoracic radial patches are also true ridges, being elevated above the surface of the dorsum. All three patches in this species end not in a single aperture or pore opening dorsally, but in five stout brown horizontal pores, which secrete a small quantity of fluffy brown wax. The dorsum in this species is covered with a large number of ex- tremely minute circular pores; the margin is also broad and clearly defined. Mr. Maskell was mistaken in assuming that the three radial patches were sufficient evidence to prove the close relationship of A. eugeniae and A. eugeniae, var. aurantiit. As a matter of fact, many of the Indian Aleurodidae possess this characteristic, however widely differ- ent they may otherwise be. (Peal.) oe no. 2156.

Other members of the genus, it will be remembered, come from the Orient. Our material of solitarius, though limited to three examples of pupa cases in balsam mounts and one pupa case on leaf, is sufficient to warrant its description, as its characteristics are distinct. The specimens were received from H. O. Woodworth, October 17, 1901, and were sent from Champaign, Illinois, where they were supposedly collected. The host is red-bud, Cercis canadensis. Pupa case (fig. 8).—Size about 1.4 by 1 mm., elliptical in shape, very dark brown to blackish in color under transmitted light. Body segments lighter and quite distinct. The transparent lunar eye- spots noted in other dark-colored forms of this genus are in this species not discernible. Dorsal and submarginal areas distinctly demarked by a suture extending all around the case. On dorsal disk are a few transparent dots, as indicated in the illustration. The setae and their arrangement can not be satisfactorily determined in the speci- mens in hand, due to their dark color, but these are probably placed in the normal way for related forms, as marlatti. Vasiform orifice (fig. 12) triangular in outline, with the surrounding lobed area typical of the genus. The operculum corresponds in shape to the outline of orifice, which it nearly fills. The lingula is not observable through the dense brown operculum. The submarginal area is quite distinct as a fluted zone all around the case. The margin is very faintly beaded by the ends of the wax tubes, the sutures between which near the margin are distinct, but are more or less anastomosed mesad (fig. 13). The marginal area shows many minute transparent dots like those present on the dorsal area. The tracheal pores on margin of case are indicated by a bilobed or trilobed structure (figs. 9, 10, and 11) which is distinct from the tracheal pores in other species of the genus thus far seen. On the leaf the pupa case appears dense black in color. There is a fringe all around of glassy wax tubes, compact basally and spreading by groups distad. These rods have a length of about one-half of width of pupa case. Dorsal area more or less covered with scales or plates of wax of general color of marginal fringe. Adults —Unknown. Type.—Cat.

Larva, first instar (fig. 2)—Length 0.03 mm., form elliptical; color pale brownish; eyespots purplish brown, and the vasiform orifice a darker brown than the remainder of larva. On the dorsum the abdominal segments are distinct. There is a pair of minute setae bordering the vasiform orifice, and there are two pairs of very long curved spines situated on tubercles, one pair on the cephalic extremity, just cephalad of the eyespots, and the other on the middle of the larva. The margin (fig. 3) is very minutely toothed, the teeth being rounded at their tips. There are 15 pairs of marginal hairs observable on the paratype specimens, though these are in such a condition that cther hairs may be present and not visible. Of the marginal hairs the caudal pair is long and the third caudal pair extremely so. The others are nearly uniform in length. The vasi- form orifice (fig. 4) is nearly triangular with the caudal extremity rounded. The operculum is rectangular and about half fills the orifice. The lingula is elongate, extends nearly to the caudal extremity of the orifice, and its tip is setose. Pupa case (fig. 5).—Length about 1.28 mm., width 1.12 mm., in broad specimens. There is considerable variation in the relative lengths and widths in different specimens; some look rather long and narrow, while others are nearly as broad as long. Color of case by transmitted light very dark brown to black. There is a distinct broad marginal rim evenly marked off from the central dorsal disk. This central dorsal area is divided into two parts: First, a central area with very little sculpturing, on which the abdominal segments are distinctly visible; and, secondly, a subdorsal area forming a band all around, but narrowing at each extremity. This is covered with numerous irregular corrugations, and the sutures of the abdominal segments are not visible upon it. The transparent eyespots are more or less crescent shaped and are located within the subdorsal area. There are also upon the dorsum many minute transparent circular pore-like places arranged in irregular or broken rings about the case. There seem to be two rows of these on each side of the middle dorsal area and one row on the subdorsal area. The vasiform orifice (fig. 6) is somewhat triangular and longer than broad. The operculum is of a similar shape and fills about two-thirds of the orifice. The inner membrane is reticulate as shown in the figure. The orifice is sur- rounded by an area similar to that present in the other species of the group, consisting of a cephalic and two lateral lobes which form a channel caudad. The marginal rim (fig. 7) is irregularly divided by a large number of sutures extending mesad on the submarginal area. ‘The outer extremities of these form shallow rounded teeth on . No. 2156.

There is a pair of small setae on the cephalic margin at about the same distance from the median line as the eyespots and a similar pair of latero-caudal setae. We have been unable to find any caudal setae similar to those present in the related species, though these may normally be present and not observable in the speci- mens we have been able to study. On the leaf we have only two specimens. These do not show any secretion from marginal wax tubes, as stated by Kuwana, and it has doubtless been broken off in our material.

Plate 48, fig. 1. Aleyrodes iridescens Bemis, Proc. U.S. Nat. Mus., vol. 27, 1914, p. 487. This species has been rather fully described by Bemis. A few details of structure may be added in order to separate iridescens from closely related forms. The submarginal papillae are about 0.03 mm. long and form a very even row. The pore-like structures 3880 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 61. on the dorsum of case are about 0.32 mm. in diameter and are arranged as shown in the figure. Those forming the row of six on the abdomen between the submarginal row of papillae and the double median row are about 0.16 mm. from the outer pores of the double median row. A channel extends from the vasiform orifice to the margin of the case. On either side of the channel is a thickened wrinkled lobe-like ridge between the orifice and the margin. We have specimens taken on Arctostaphylos species, near Camp Rincon, San Gabriel Mountains, California, July 4, 1911, by P. H. Timberlake. These specimens show some differences from the paratypes mentioned above. The most noticeable difference is in the submarginal papillae, which are elongate in these specimens and measure about 0.048 mm. ‘The pores also are somewhat larger. Paratype.—Cat. No. 7084, U.S.N.M. ALEUROPARADOXUS PUNCTATUS, new species. Plate 48, fig. 2. Two collections of this species are in the Bureau of Entomology. Q. No. 1980 was taken on Lithraea caustica, at Santiago, Chile, by Manuel J. Rivera, October 25, 1905, and Q. No. 8821 was taken on Quillaja sapororia and sent from the same city by Carlos E. Porter in March, 1905. Pupa case—Size 1.44 mm. by 1.12 mm., subelliptical, broadly rounded at the ends. The margin of the dorsal disk shows a very irregular, somewhat thickened line. The median dorsal abdominal ridge is armed on each segment with three to five irregular pore-like areas, which are usually crowded together. These are much smaller than the corresponding ones in iridescens. The transverse cephalic row of pore-like areas upon the thorax consists of sometimes as many as 18. On the submarginal area of the abdomen some dis- tance mesad and often occupying a part of the margin of the dorsal disk there is an irregular row of minute pore-like areas. This row is most often of three pores in thickness, but often is only a single irregular row. Sometimes it is scarcely visible at all. The pores forming this row are much smaller than those present on the similar region of widescens. The papillae-like structures forming a row about the case just within the margin are in this species short, ex- tending mesad only about 0.016 mm., but the suture-like markings between them extend considerably farther mesad. In iridescens, on the other hand, the sutures between the papillae extend scarcely mesad of the papillae themselves. Comb of the thoracic tracheal fold very similar to that of iridescens, consisting of three teeth. Vasiform orifice typical for the genus, about 0.112 mm. by 0.096 mm. in size and about 0.128 mm. from caudal margin. There is a channel * no. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE &€ BAKER. 381 extending from the caudal edge of the orifice to the margin of the case. The thickened area on either side of this channel ends on the margin in two narrow irregular lobes. These differ from the corre- sponding lobes of iridescens in extending to the margin or a little beyond it. The color under the microscope is a very dark brown. On the leaf the pupae appear as black disks without waxy secre- tion, excepting short pencils of wax from the pores of the tracheal folds.

Ser. 27, pt. 2, Bur. Ent. U. S. Dept. Agr., 1914, p. 98. Pupa case usually flat, elliptical, oval, or subcircular in outline, often notched on cephalo-lateral margins; some species are elongate; color varying from a transparent yellowish or whitish to black, but mostly dark brown; many species variously dotted with darker markings; margin toothed, wax tubes moderately developed, inci- sions shallow; thoracic and caudal tracheal folds present and in most cases plainly visible and ending on the margin in a distinctly differentiated comb of teeth from which arise pencils of waxy secre- tion, differing from the more or less amorphous secretion of wax surrounding the case, secreted by the marginal wax tubes. Dorsum with the disk not separated from the submarginal area and without prominent pores or papillae, though usually with a number of minute clear pores. (In rare exceptions there are many wax pores.) Vasi- form orifice small, transverse, rounded, or elongate, the inner margin rarely armed with teeth; operculum filling from a third to all of the orifice and obscuring the lingula. Adults with wings unmarked, clouded, or spotted; the radial sector of forewing with a single flexure; no spur of the media, but the cubitus faintly indicated. Antennae of seven segments, segment III the longest; the other distal ones subequal, with IV, however, usually the shortest. Claspers of male considerably curved at their distal extremities and possessing a number of prominent spines. Proximad of the distal spur of each clasper there is either a lobed structure or other smaller spurs. Type.—Aleuroplatus quercus-aquaticae (Quaintance). KEY TO SUBGENERA OF THE GENUS ALEUROPLATUS. 1.

ALEUROPLATUS (ALEUROPLATUS) BERBERICOLUS, new species. Plate 50, fig. 1; plate 49, figs. 1-4. On January 27, 1908, J. W. Cockle collected pupa cases of this species at Kaslo, British Columbia, on Berberis aquifolium. Later collections by Mr. Cockle from the same plant proved to represent other species, and adults supposed to be those of berbericolus, and taken at another time, are those of a species of Aleyrodes. Speci- mens of berbericolus are also in the collection from Mexico City, collector and date unknown, and from Toluca, Mexico, on Jlez, collected June 24, 1897, by A. Koebele. Pupa case (pl. 50, fig. 1).—Size 0.88 by 0.656 mm. Shape ellip- tical, constricted across the thoracic folds. Dorsum with the abdominal segments quite distinct, thorax with a more or less defined arrow-shaped structure resembling that found in the genus Aleurotrachelus. Suture separating the thorax and abdomen curved cephalad beyond the third thoracic segment. Lateral margins of the abdominal segments on the median dorsal area marked with many minute, dark, pore-like spots. These sometimes extend in a row across the edges of the segments. Margin (pl. 49, fig. 1) composed of evenly rounded, moderately shallow teeth from which there extend mesad suture-like markings. Thoracic tracheal comb (pl. 49, fig. 2) composed of three or four rather prominent teeth with serrate mar- gins; caudal comb similar. Submarginal and subdorsal areas with irregularly scattered minute pore-like structures. Vasiform orifice (pl. 49, fig. 3) subcircular in outline with the margins thickened; operculum filling about half the orifice, subtriangular in shape, though oo4° * PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 51. broad and rounded at the apex. The entire orifice is covered on its upper surface with a membrane, the opening in which is smaller than the orifice itself. Color of case yellowish brown, with the median portions darker brown. Eyespots purplish. The case is closely appressed to the leaf and surrounded with a rather narrow glossy wax fringe, in which may be distinguished the pencils of white wax from the thoracic and caudal combs; the marginal area is dark brown and the dorsal disk very dark brown or black. The disk shows a longitudinal keel, and the body segments are quite distinct. Adults.— Unknown. Described from pupa cases in balsam mounts. Type lot from Kaslo, British Columbia. Type.—Cat.

Paratype material of this species in the collection of the Bureau of Entomology is composed of pupa cases only. The description given by Hempel ? and cited under this species by Kirkaldy in his catalogue of the family refers to quite another insect, Dialeurodicus cockerelli Quaintance. Pupa case (pl. 50, fig. 2)—Size 1.36 by 1.056 mm. Shape oval, with cephalic portion the narrower. (The figure given by Ihering shows the cephalic and caudal portions equally broad. Our speci- mens, however, are not so shaped.) Dorsum with a distinct rhachis, the segments of the abdomen extending out from it as prominent ridges. Submarginal area with a few small, clear, circular, pore-like areas. Vasiform orifice (pl. 49, fig. 6) somewhat longer than that shown for the type and with the membrane on the inner latero-caudal part sometimes thrown into minute folds. Margin with distinct and, for the genus, rather prominent teeth, between which minute ones are often situated. Thoracic pores ending on margin in an even comb of usually four closely placed teeth (pl. 49, fig. 5). Color on the leaf brownish black; under the microscope, dark brown.

Of this material that collected by Urich in 1912 has been taken as type, for in this lot are examples of eggs and larvae and some fragmentary adult females. Egg (pl. 49, fig. 7).—Size 0.24 by 0.112 mm.; stalk 0.048 mm. Shape almost hemispherical, the straight side some distance from the stalk. Color yellow, stalk brownish. No sculpturing present. Larva (second instar?).—Size 0.65 by 0.4 mm. Color light brown; eyespots transparent and near each a red pigmented area; median dorsal region with many dark pore-like markings. Abdom- inal segments indicated only on the median dorsal area. Thorax with a slight indication of a central ridge, and with three pairs of prominent spines; those on the last two thoracic segments are long and knobbed (pl. 49, fig. 9), while the third pair, between the eye- spots, are shorter, thicker, and tapering (pl. 49, fig. 10). Latero- cephalad of the vasiform orifice is another pair of these thick, taper- ing spines of about the same length as the orifice. The orifice itself is situated on a somewhat differentiated area, which extends to the caudal margin of the case. Two long curved spines arise from this, near the margin. The teeth of the margin are prominent. Pupa case (pl. 51, fig. 1).—Size 0.976 by 0.736mm. Colordark brown, usually more heavily pigmented on the thorax; yellow specimens or specimens variegated with yellow are, however, not met with as in variegatus. There are many black dots scattered over the dorsum, as seen in most members of this genus. The case is flat, and the abdominal segments are distinct only on the median dorsal area. Suture separating the thorax and abdomen not extending cephalad beyond the third thoracic segment, but extending about even with it.

Margin composed of moderately sized teeth which are serrate; from these there extends mesad a series of irregular suture-like markings, which, however, do not extend so far as in variegatus. There is, on the other hand, the same thickened area mesad of the marginal comb of the thorax, and it is covered with the same minute circular markings, but these also extend mesad from it. A similar thickened area and a similar row of markings are found caudad of the vasiform orifice. Latero-cephalad of the orifice there is a pair of rather short spines. The orifice itself (pl. 49, fig. 8) is subcircular in outline, thickened latero-caudad; the operculum nearly fills the orifice and is striate above. On leaf the case is jet black and surrounded by a conspicuous fringe of dirty white or yellowish wax, amorphous basally in the more mature specimens, but with numerous lighter pencils or threads of wax radiating from the case, extending well beyond the amorphous portion. In less advanced pupa cases the amorphous basal wax is mostly absent, and the radiating wax pencils are very conspicuous. Adult female.—The fragmentary condition of the available speci- mens of the female will not permit of a good description. They are yellow in color with dark brown eyes and unmarked wings. The body is about 0.8 mm. long and the forewings measure about 1.04 mm. in length. Adult male—Unknown. Described from eggs, larvae, pupa cases, and fragmentary females in balsam mounts. Type.—Cat. No. 19193, U.S.N.M. The specimens on Hugenia michelit are somewhat lighter than typical, have a slightly more pronounced constriction across the thoracic folds, and the abdominal segments are not so distinct.

SUBFAMILY’ ALEYRODINAB—QUAINTANCE & BAKER. 887 Pupa case (pl. 51, fig. 2).—This species has been fully described by Quaintance and by Bemis. The minute pore-like structures forming a submarginal row (pl. 49, fig. 11) as in the species related to coronatus are quite similar to those met with in vinsonioides, oculireniformis, and oculiminutus. On the mesal portion of the abdomen of coronatus there is usually but one row of pores on each side, and not three rows as in the species just mentioned. On the thoracic region these pores are quite scarce in coronatus, whereas they are numerous on the other species mentioned. The eyespots also are not clear, transparent areas as in the related species, but are pigmented and usually dark brown in color. The comb of teeth on the margin of case, at the extremity of the thoracic folds, is not distinct. The vasiform orifice (pl. 49, fig. 12) is unusual. It is very elongate, and the operculum is exceptionally small, filling not half of the orifice. Type.—Cat. No. 4238, U.S.N.M. ALEUROPLATUS EURYAE (Kuwana). This species was included in the genus Aveuroplatus in the writers Classification of the Aleyrodidae,! It shows considerable variation from the type, and a study of three undescribed species undoubtedly closely related to euryae leads us to believe that these four species belong to a distinct genus. Euryae is, therefore, not here considered with the species of Alewroplatus. ALEUROPLATUS (ALEUROPLATUS) FICUS-RUGOSAE, new species. Plate 49, figs. 13-16. Only one collection of this species is at hand. It was taken on Ficus rugosa at the Royal Botanic Gardens, Calcutta, India, by R. S. Woglum, December, 1910. The pupa case is very like that of species of Dialeurodes. Pupa case (pl. 49, fig. 13).—Size 1.6 by 1.32 mm. Shape elliptical, very slightly narrower on the thoracic portion. Dorsum slightly rounded, segmentation scarcely distinguishable, margin with- out teeth, but with a number of suture-like markings extending mesad.

This species was described by Cockerell, and the different stages were described by Bemis. Several details may here be added: Pupa case (pl. 52, fig. 1)—The suture separating the thorax and abdomen is curved cephalad to, or perhaps a little beyond, the third thoracic segment. On each of the two caudal segments of the thorax there is a pair of prominent spines situated on tubercles. On the cephalic part of the thorax about on the region where the eyespots are usually located is a pair of tubercles similar to those on which the spines just mentioned are situated. The thoracic tracheal folds are evident and the comb (pl. 49, fig. 17) consists of two prominent teeth with serrate margins, and differing somewhat from the caudal comb (pl. 49, fig. 18). The vasiform orifice (pl. 49, fig. 19) is subcircular in outline with the margin thickened. The operculum fills about half the orifice and the upper surface of the latter is covered with a membrane similar to that found in berbericolus and ovatus. On the leaf the case appears jet black and is surrounded with a conspicuous copious secretion of gelatinous, yellowish wax. Adults.—Unknown. Type.—Cat. No. 8998, U.S.N.M.

SUBFAMILY ALEYRODINAB—QUAINTANCE ¢€ BAKER. 389 Of these collections Quaintance No. 6752 has been selected as the type lot on account of the abundance of the material. The species is very striking on account of the large, solitary, indented tooth (comb) of the thoracic and caudal folds and on this account is very easily separated from others in the genus. Pupa case (pl. 52, fig. 2).—Size 1.36 by 1.04 mm. Color dark brown to black; under the microscope dark brown with median darker pigmentation. The genera! appearance of dorsum under the microscope is quite similar to that of coronatus, owing to the median dark pigmentation. The margin is composed of moderate sized, evenly rounded teeth and from these flutings extend for a short dis- tance mesad. At the base of these flutings there is a row of minute pores similar to those met with in several other members of the genus. The abdominal segments are distinct only on the median dorsal area and each segment possesses a transverse row of pores. The suture separating the thorax and abdomen is short, not extending on each side much more than halfway to the margin; it is very little if at all curved cephalad. The thoracic and caudal tracheal folds are armed at their extremities with a prominent elongate tooth (pl. 49, fig. 20) and this is situated within a distinct sinus. The latero-caudal setae are long. The vasiform orifice (pl. 49, fig. 21) is subcircular in out- line with the inner rim thickened caudad, and seemingly lobed; it is nearly filled by the operculum. In some specimens the transverse row of pores on the abdominal segments are not visible and in others the thoracic area is covered with many minute pores. Adults —Unknown. Described from pupa cases in balsam mounts and dry upon the foliage. Eggs and a few larvae are present in the material, but as other species are also present it is doubtful to which species they belong. Type.—Cat. No. 19196, U.S.N.M. ALEUROPLATUS (ALEUROPLATUS) MYRICAE, new species. Plate 54, fig. 1; plate 53, figs. 1-4. Specimens of this species were taken by the senior author at Griffin, Georgia, April 25,1899. They were living on a plant believed to be a species of Myrica. Pupa case (pl. 54, fig. 1.)—Size 0.832 by 0.512 mm. Shape nearly elliptical; dorsum somewhat evenly arched; suture separating the thorax and abdomen very little curved cephalad. Margin (pl. 53, fig. 4) composed of shallow rounded teeth, but somewhat irregular, several teeth or groups of teeth being extended farther than the others. Just within the margin there is a row of minute pore-like structures not unlike those of coronatus and related species.

Vasiform orifice (pl. 53, fig. 3) subcircular in some specimens, in others elongate, the rim thickened, particularly on the caudal margin. Oper- culum about half filling the orifice in some specimens, but in those with the more elongate orifice, it is smaller; caudal spines very stout. Thoracic and tracheal folds scarcely distinguishable and not armed on margin with any special comb. Adult male.—Color yellow, shaded with brown; eyes dark brown, wings in balsam mounts transparent. Antennae (pl. 53, fig. 2) im- bricated, segment III with a circular distal sensorium, and armed with along spine. In some specimens the spine is absent. Segments IV to VII imbricated; V and VII each with a distal sensorium. Pro- portions of the segments as follows: I, 0.064 mm.; VI, 0.09 mm.; VI, 0.09 mm. Claspers (pl. 53, fig. 1) 0.112 mm. long, rounded at the distal extremity, and acute. Just within the distal spur there isa bilobed structure, which sometimes shows a small third lobe on the proximal part; spines few and prominent. Length of forewing 0.88 mm., length of body from vertex to tip of claspers about 0.96 mm. On the leaf the case appears jet black, convex, and without waxy secretion. Adult female.—Similar in color to the male, but larger. Distal segment of antennae armed with a prominent spine on its proximal third and that part of the segment distad to this tapering. Size varia- ble, from 0.96 to 1.44 mm. Forewings from 0.96 to 1.2 mm. Described from pupa cases, males and females in balsam mounts, and pupa cases on foliage. Type.—Cat. No. 19198, U.S.N.M. ALEUROPLATUS (ALEUROPLATUS) OCULIMINUTUS, new species. Plate 54, fig. 2; plate 53, figs. 5-7. Specimens of this species were received from Mr. F. W. Urich, April, 1913, and were taken on Ficus species (‘‘metapel’’) in Trinidad. This is the only collection of the species that we have. Pupa case (pl. 54, fig. 2).—Size 0.832 by 0.672 mm.; shape oval, broadest across the abdomen. Suture separating the thorax and abdomen not distinct. Sutures marking off the abdominal segments very faint, not darkened in color as are those of related species. Color black; margin of case (pl. 53, fig. 5) with evenly rounded shallow teeth, each tooth with a clear pore at its base. About 0.48 mm. from the margin of case there is a submarginal row of small pores. These are arranged alternately, forming a zigzag row around the case. Between this row and the margin of the case there is a checkered area somewhat similar to that found in vinsonioides, but the present species shows at least two rows of inclosed areas and one No. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 391 row of open marginal areas, whereas vinsonioides shows only one row of inclosed areas and one row of open marginal areas. On the dorsum there are also other minute pores arranged as shown in figure 5, plate 53. The arrangement of these is very similar in oculiminutus, vinsonioides, and oculireniformis. The eyespots are very minute, about equal in size to the pores of the submarginal area. The eyespots may be distin- guished at once from the submarginal pores from the fact that they are transparent, whereas the poresarenot. They aremuch nearer the mar- gin than is usual, being on the same line as the submarginal row of pores, or even nearer the margin (pl. 53, fig. 5). The dorsum, mesad of the submarginal ring of pores, is without checkered markings. Vasiform orifice (pl. 53, fig. 7) of about equal width and length, the operculum filling a little more than half of it. Caudad of the orifice near the margin of the case there is a pair of thick spines close together, and the usual pair is present latero-cephalad of the orifice. On the leaf the cases are shining black. There is no dorsal waxy secretion, but there is an irregular white waxy marginal fringe. In some specimens this mass fuses into a yellow, semitransparent wax, terminating on the periphery in numerous squarish teeth. Adult female.—The females present are fragmentary and it is im- possible to give from them a complete description. Color yellowish, with yellowish or dusky shadings. Eyes dark brown. Forewings with dusky brown markings as shown in figure 6, plate 53. Length of forewing 0.88 mm.; hind wing uniform dusky. The markings of the forewing of this species are very similar to those of oculireniformis. Adult male-—Unknown.

Plate 55, figs. 1-10. One lot only of this species is in the bureau collection. It was taken by F. Rocha at Ceara, Brazil, in January, 1906, on Passiflora. Two other species are very closely related to the present one, namely vinsonioides Cockerell and oculiminutus. The separation of these species is made on the pupa case, as adults of vinsonioides in the collection are fragmentary females only. Egg (pl. 55, fig. 1)—Color yellow, in a few cases brownish; shape oval with one side flattened; stalk not exactly at the base, but farther from the flattened than the rounded side of the egg. Surface without apparent sculpturing; length 0.192 mm. Pupa case (pl. 55, fig. 2).—Shape oval, broadest across abdo- men. Size 0.912 by 0.72 mm.; some specimens smaller. Color dense black, with eyespots sometimes showing a clear transparent 392 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 51. area, while in other specimens these are brown in color. These eye- spots are reniform and are much larger than those of the two related species (pl. 55, fig. 9). Margin (pl. 55, fig. 3) composed of closely set and evenly rounded teeth, each one with a minute circular pore at its base. Dorsum with many small circular pores arranged as shown in the figure. The submarginal row of pores forms a fairly even line around the case. That part of the dorsum between these pores and the marginal teeth is not striate (pl. 55, fig. 3), though the mesal portion of the dorsum is. Suture separating the thorax and abdomen evenly rounded on each side. Vasiform orifice (pl. 55, fig. 4) usual, longer than broad, and almost entirely filled by the operculum. On the leaf the case is jet black and there is apparently no waxy secretion of any kind. Adult male—Color yellowish or slightly brownish, with dusky appendages and dark brown eyes. LKyes not divided, but the upper and lower eyes joined by six or eight lenses in pairs or triplets (pl. 55, fig. 8). Antennae with proportions as shown in figure 7, plate 55; segment III imbricated and with two distal sensoria; each of these is usually armed with a central process. Segment V with a distal sensorium and segment VII with a sensorium near its middle. Forewing with smoky brown markings, as indicated in the figure (pl. 55, fig. 10). Hindwing uniform pale smoky. Claspers 0.128 mm. long, slightly curved, somewhat pubescent, and armed with a number of stout spines, as shown in plate 55, figure 6; outer distal edge form- ing a rather distinct prong, and the inner portion with a distinct double lobe. Penis (pl. 55, fig. 5) with a distinct shoulder. Length from vertex to tip of claspers 0.72 mm. to 1.04 mm. Adult female.—Similar in general character to the male. Length of antennae 0.396 mm. Average length from vertex to tip of cauda 0.92 mm.; length of forewing about the same. Described from males and females, pupa cases, and eggs in balsam mounts. Type.—Cat. No. 19200, U.S.N.M.

It was taken on Berberis trifoliata at College Station, Texas, by Wilmon Newell, in March, 1912. Pupa case (pl. 56, fig. 1).—Size 0.96 by 0.624 mm. Shape oval, broadest across the thorax; caudo-lateral margins more or less straight. Abdominal segments distinct, reaching almost to the margin. Suture separating the thorax and abdomen recurved cephalad about on line with the third thoracic segment. Margin composed of evenly rounded shallow teeth; comb of the thoracic x No. 2156.

Vasiform orifice (pl. 53, fig. 9) subcircularin outline, with the margin somewhat thickened, the operculum filling about two-thirds of the orifice, which latter is covered with a membrane. Color dark brown to black, darker across the sutures of the abdomen. On the abdominal segments there are also minute, dark, pore-like markings. The developing eyes within the body are seen as large black patches near the cephalic margin, and on some specimens there are small yellowish semitransparent eyespots. Cephalad of the vasi- form orifice there is a thickened area darker than that which sur- rounds it. On the leaf the case is surrounded with a copious secretion of gelatinous, semitransparent wax. Around margin of case the wax is whitish, and a pencil of white wax extends caudad from caudal end of case. Adults Unknown, Described from pupa Cases in balsam mounts. Type.—Cat. No. 19201, U.S.N.M.

Pupa case (pl. 56, fig. 2).—Size 0.912 by 0.72 mm.; many speci- mens considerably smaller; color dark brown or black. Outline oval, narrowest across cephalic portion, slightly constricted across the thoracic folds, and very slightly at the caudal fold. Dorsal sutures indistinctly marked. Margin with shallow rounded teeth and within margin on the submarginal area there is a series of minute pores irregularly arranged. Thoracic folds distinct, the comb on the margin of these composed of four or five long, prominent teeth (pl. 53, fig. 10). Caudal comb of a similar character. The teeth on the combs of this species are much more prominent than those of any other dark form thus far known, and are quite distinctive. 394 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 51. Vasiform orifice (pl. 53, fig. 11) subcircular in outline, with the rim somewhat thickened. The operculum is small and fills only about the anterior third of it in some specimens, while in others it fills about half. It tapers caudad. The usual setae latero-cephalad of orifice are absent. Color dark brown to black; under the microscope vary- ing shades of brown. Adult male.—Color yellowish red, shaded with black; forewings maculate as shown in plate 53, figure 14; hindwings uniform pale dusky; legs dusky, excepting the joints, which are yellowish; claspers and tip of abdomen dusky. Eyes and tip of labium brown to black. Antennae absent from the specimens in hand with the exception of one antenna of one specimen. From this it is impossible to make out the relative proportions of the segments, as the specimen is much shrunken. The condition, however, is sufficient to make out that many distinct transverse ring-like imbrications cover the segment. The third segment possesses a long, stout spine. Each clasper (pl. 53, fig. 12) is armed at its extremity with prong-like projections. The two distal ones of these are rather long and acute, whereas the more proximal one is short and conical. A number of spines are present, and the clasper is minutely pubescent. The penis (pl. 53, fig. 13) is enlarged at its distal extremity into a disk-like structure, which seems to have an opening or depression within it. Length of claspers 0.108 mm.; length of insect 0.8 mm.; length of forewing 0.64 mm. Adult female——Similar to the male; color of body almost wine colored; costal margin of forewing distinctly wine colored. Length of insect 0.88 mm. In some specimens the dark markings of the wings are more extended than in the figure. Antennae absent from all the specimens. Described from pupa cases and males and females in balsam mounts. Type.

This species was described from Florida by the senior author and was inadvertently included in Tetraleurodes by the present writers in Classification of the Aleyrodidae.t' The species is very abundant on cranberries, and many collections from these plants were received from the late Dr. C. W. Hooker, taken at Cranmoor, Wisconsin, in 1910. In these collections a large percentage of the pupa cases 1 Bulletin 27, Tech. Ser. Bureau of Entomology. * no. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 395 represent a species of Tetraleurodes. It is evident, however, that these bear no relation to the present species. Specimens have been received also from H. B. Scammell from New Egypt, New Jersey, May 21, 1914, on cranberry, and from Pemberton, New Jersey, July 18, 1914, on blueberry. Pupa case (pl. 57, fig. 1).—Size 0.96 by 0.704 mm. Shape oval, narrowest across the thorax. Abdominal segments not distinctly seen on account of the dark color, but in specimens which are suffi- ciently clear they are seen to extend almost to the margin of the case. Suture separating thorax and abdomen considerably curved cephalad, but not past the third thoracic segment. Margin composed of evenly rounded, very shallow teeth, from which suture-like markings lead mesad and give the appearance of a pore-like structure. Thoracic tracheal comb distinct; composed of usually four prominent teeth, which are evenly rounded and have at their bases clear areas similar to those at the base of the marginal teeth (pl. 53, fig. 15). Caudal tracheal fold armed with a comb similar to those on thoracic margin. Vasiform orifice (pl. 53, fig. 16) elongate, with the rim much thickened, the operculum filling about half the orifice. Setae latero-cephalad of orifice and about halfway between orifice stout and long. Dorsum with a few minute pores irregularly arranged. Transparent eyespots absent; color dark brown to black. Adult male.—Color yellow, shaded with reddish brown on the tho- rax; eyes and tip of labium dark brown; wings transparent, the costal margins yellowish. Antennae imbricated; segment III 0.128 mm.; segment IV 0.02 mm.; segment V 0.032 mm.; segment VI 0.046 mm.; segment VII 0.05 mm. Segment III is armed with a distal, circular, fringed sensorium, and segment VII is armed near its middle with a prominent spine which extends beyond the distal extremity of the segment. Clasper 0.112 mm. long, slightly pubescent, distad, and armed with a few stout spines; distal spur of the claspers acute, and just mesad of the spur is a double-lobed structure. Length of insect from vertex to tip of claspers 1.152 mm.; length of fore- wings 0.96 mm. Adult female.-—Similar to the male in general appearance.

Several species of the genus are very closely related to it, especially validus, in which 396 PROCEEDINGS OF THE NATIONAL MUSEUM. Vou. 51. the suture separating the thorax and abdomen is similarly curved. Quercus-aquaticae, however, has no dorsal spines on the thorax as has validus, and the pupa case is more constricted across the thorax. Pupa case (pl. 57, fig. 2).—Shape oval, quite distinctly con- stricted across the thorax in the region of the thoracic folds. Suture separating the thorax and abdomen curved cephalad and almost reaching the margin of case on each side near the thoracic breathing pore. Abdomen on the dorsal disk with two rows of small clear pores at the lateral margins of the indications of segments. Lateral thoracic and caudal breathing folds indicated by dark areas, the combs con- sisting of usually four small, rounded teeth (pl. 53, fig.17). Vasi- form orifice (pl. 53, fig. 18) short and broad. Thorax with variable pigmentation, but without distinct spines. Size variable, larger specimens about 1.12 mm. long. Type.—Cat. No. 14782, U.S.N.M. ALEUROPLATUS (ALEUROPLATUS) SCULPTURATUS, new species. Plate 58, fig. 1; plate 59, figs. 1-4. This remarkable species was taken on Helicorna at Panama by Mr. August Busck, April 5, 1911. It shows the most prominently devel- oped rhachis in the genus, having this structure much more developed than has cockerelli. The pupa case is also very large, being nearly twice as long as in some other species of the genus. Pupa case (pl. 58, fig. 1).—Size variable, about 2.4 by 1.76 mm. Shape elliptical; dorsum arched and possessing a very distinct rhachis, from which very prominent sutures extend laterad, marking the abdominal segments, and from which a large expanded portion extends cephalad. Color dark brown to black with this median area of a bright yellow, sometimes shaded with brown. Margin (pl. 59, fig. 2) composed of very shallow, evenly rounded teeth. From these suture-like markings extend for a very short distance mesad. Within these are three or four rows all around the case of small rounded papilla-like pores, mesad of which there are no pores until the edge of the rhachis is reached. On each side of the rhachis on most of the abdominal segments there is a group of three or four small circular pores (pl. 59, fig. 1), and a group of six or seven similar ones is situ- ated on each side of the median Ine on the enlarged median thoracic structure. Laterad of these there is a reniform thickening of the integument. Thoracic tracheal folds evident, the combs being com- posed usually of two teeth (pl. 59, fig. 4). Vasiform orifice (pl. 59, fig. 8) broad and short, the operculum filling almost the entire ori- fice. Setae usually found latero-cephalad of the orifice absent. Adults —Unknown.

This species is in many ways quite different from others in the genus. The rows of papillae-like pores on the submarginal area are not met with in any other species and the huge size and prominent rhachis are very distinctive. A. cockerelli, however, scems to show affinities with the present species. ALEUROPLATUS (ALEUROPLATUS) TRANSLUCIDUS, new species. Plate 58, fig. 2; plate 60, figs. 8-14. Two collections by R. S. Woglum prove to be this species. Both were made from orange. The first collection was made at Lahore, India, date unknown, while the second lot was taken at Wazirabad, India, in November, 1910. This species is the only one in the sub- genus, so far as known, which has an almost colorless transparent case. Pupa case (pl. 58, fig. 2; pl. 60, figs. 8 and 9).—Size 0.912 by 0.72 mm.; shape nearly elliptical, slightly constricted across the region of the thoracic folds; color semitransparent, whitish yellow; eyespots reddish brown. Dorsum with the sutures very indistinct. Margin (pl. 60, fig. 12) with evenly rounded shallow teeth, from which suture-like markings extend for a short distance mesad. Thoracic folds distinct, the comb composed of three or four rather prominent teeth (pl. 60, fig. 11). Vasiform orifice (pl. 60, fig. 10) subcircular in outline, with the latero-caudal margin thickened. These margins are covered with numerous dot-like markings or possibly very minute setae. The operculum nearly fills the orifice and is similar to it in shape, though much more compressed on the lateral margins. The pair of setae usually present near the cephalo- lateral margins of the orifice are in this species a pair of spines of about the same length as the orifice. On the leaf the case is surrounded with a liberal, semitranslucent wax, in which may usually be distinguished many fine radiating lines of lighter wax. Owing to the evident adhesiveness of the wax the entire insect often becomes covered with dirt, appearing on the leaf as a dirty -brown spot. Adult male.—Color reddish, becoming yellow on the vertex, legs, and genital segments. Forewings with dark maculations as shown in figure 14, plate 60, the costal margins red. Hindwings uniform smoky; legs dusky, excepting at the joints; genitalia also dusky; eyes dark brown. Antennae absent from the specimens in hand; claspers (pl. 60, fig. 13) with numerous prominent spines, the distal extremity with two prongs, one long and one short one, and with a somewhat conical projection; proximad of these a slight pubescence visible. Penis usual; length of claspers 0.144 mm. Length of insect from vertex to tip of claspers 0.96 mm.; length of forewing 0.64 mm. 398 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 51. Adult female.—Similar in color to the male. The hindwings some- ’ times have transparent patches. Length 0.96 mm.; forewing 0.848 mm. The females, as in the males, lack the antennae. Described from pupa cases, males and females in balsam mounts, and pupa cases dry on foliage. Type.—Cat. No. 19204, U.S.N.M. The adults of this species are very similar in many ways to those of Aleurocanthus citriperdus. The red color met with in this species as against the yellow color in citriperdus is not always a good distinc- tion. In citriperdus, however, the claspers of the male possess fewer spines, and are less curved at their distal extremities. ALEUROPLATUS (ALEUROPLATUS) VALIDUS, new species. Plate 61, fig. 1; plate 59, figs. 5-7. This species was received from Prof. S. F. Ashby on April 30, 1914, marked Hope, Kingston, Jamaica, host unknown. It is more nearly related to quercus-aquaticae than to any other species of the genus, but may be distinguished from it by the presence of prominent dorsal thoracic spines and by the character of the suture between the thorax and abdomen. Pupa case (pl. 61, fig. 1).—Size 0.96 by 0.72 mm. Shape almost elliptical, with a slight constriction across the thorax at the region of the thoracic folds. Color brown, sometimes with a darker pig- mentation along median area and around suture separating thorax and abdomen. Eyespots irregular, smaller than in quercus-aquaticae; extremities of thoracic folds not heavily pigmented. Form flat, the abdominal segments distinct only on the median dorsal area. Suture separating thorax and abdomen curved cephalad almost to the mar- ginal extremities of the thoracic folds. In this character the species is similar to quercus-aquaticae. The suture is curved as far cephalad as in the type-species, but after leaving the median suture it is not curved as much caudad before its cephalic recurve as in that form. Thorax with two pairs of prominent clubbed spines, one pair on the median portion of each of the two caudal segments. Pores of the submarginal area arranged in groups very similar to those of quereus- aquaticae. Comb of the thoracic fold (pl. 59, fig. 7) armed with usually four teeth, which are very little larger than the other mar- ginal teeth (pl. 59, fig. 5).

SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 399 ALEUROPLATUS (ALEUROPLATUS) VARIEGATUS, new species. Plate 61, fig. 2; plate 59, figs. 8-11. This species was taken in the gardens of the National Museum at San José, Costa Rica, by Ad. Tonduz, April 3, 1914. It was collected from the leaves of a species of Psidium. It is remarkable on account of the variegated character of several of the pupa cases. Pupa case (pl. 61, fig. 2).—Size 0.96 by 0.72 mm. Shape tend- ing to oval, narrowest across the cephalic portion and slightly con- stricted in the regions of the thoracic pores or combs, form flat. Abdominal segments distinctly separated only on the median dorsal region. Suture separating the thorax and abdomen extending in some specimens not at all and in others a very short distance cephalad of the suture of the caudal thoracic segment. Color varymg from a yellow to asmoky brown. In specimens that are only partially dark this dark area is on the median dorsal region. Specimens showing the entire dorsum dark have the marginal teeth all around, the pores and the tubercles on which the spines are located transparent yellow; these structures then stand out very clearly. The thorax is armed with a pair of prominent clubbed spines on the median portion of the second and third segments (pl. 59, fig. 9), and another less prominent pair between the eyespots, which last are transparent and irregular. Scattered over the dorsum there are many minute clear pores. Vasiform orifice (pl. 59, fig. 11) subcircular in outline, with the margin thickened at its caudal part and armed within by minute striations; operculum straight on its cephalic portion, rather elongate, nearly filling the orifice. Just caudad of the vasiform orifice, and nearly to the margin of the case, there is a thickened area which extends to form the caudal comb of two teeth. On each side of this thickened area arise the spines which form the caudal pair, and the area itself is connected with the caudal margin of the orifice by a series of minute markings. In the dark specimens this small dotted region is outlined with a row of larger clear pores (pl. 59, fig. 11). The pair of spines latero-cephalad of the vasiform orifice are as long as the orifice itself. Region of the thoracic tracheal fold with a similar thickening some distance from the margin, which thickening is covered with similar minute markings (pl. 59, fig. 8). Teeth of the margin rather short, not acute, but rounded and cov- ered with minute serrations (pl. 59, fig. 10). Extending inward from these teeth are irregular suture-like markings which meet a second series of such markings on the subdorsal area. On the leaf the case appears black and is surrounded with a dirty white waxy secretion, with many conspicuous radiating threads of wax. Adults —Unknown.

The species is also in the collection from Matanzas, Cuba, and was collected by N. L. Britton and Percy Wilson, September 9, 1903, and forwarded by Prof. F. S. Earle. It was taken on Nectandra. Pupa case.—Size 1.056 by 0.832 mm. Shape oval, broadest across the abdomen. Abdomen distinctly marked off from the thorax, the suture separating them not curving distinctly cephalad, as in some other members of the subgenus. Abdominal segments flat. Color under microscope brownish black, with a pair of small, clear, circular eyespots on the cephalic portion of the case. Dorsum of case with a number of minute clear circular pores arranged as shown in the figure. The submarginal row of these pores is a con- siderable distance from the margin (0.096 mm.) and in this char- acter is distinct from the two other closely related forms, oculireni- formis and oculiminutus. The submarginal area between this row of pores and the margin of the case is marked with a series of lines and checks (pl. 59, fig. 14). The outer part of this lined area is more than twice the width of the inner, while on the cephalic portion of case there is sometimes part of a third series. Mesad of this submarginal row of pores there is no checked area as in ocu- lireniformis. The margin itself is armed with a closely appressed series of evenly rounded shallow teeth, and the teeth of the comb at the ending of the thoracic folds are scarcely distinguishable from the remainder of the margin (pl. 59, fig. 13). Vasiform orifice (pl. 59, fig. 12) usual, more elongate than that of the type. Adults.—Unknown. Type.—Cat. No. 19207, U.S.N.M. ORCHAMUS, new subgenus.

This species was described from ‘‘mandioca doce” at Rio de Janeiro. The one character given in the description which would make the recognition of the species possible is the row of submarginal bristles. In the collection of the Bureau of Entomology there is a species showing submarginal bristles. It was taken on cassava (Manihot utilissima Pohl) at Rio de Janeiro by F. Noack, date unknown. ‘There seems little doubt, therefore, that this is the species described by Goeldi. Egg (fig. 1).—Length 0.144 mm.; considerably curved, the stalk arising near the base on the convex side; color yellowish brown, with- out sculpturing. Early larva (fig. 2).—Size 0.304 by 0.176 mm.; shape elliptic; dorsum not arched, abdominal segments distinct; median dorsal area with two patrs of vasiform spines similar to those on the larvae of floccosus; submarginal area with a row of prominent spines which are longer than the vasiform spines on the middle of the dorsum. There are six pairs of these on the thoracic region and only three pairs on the abdominal region of the specimens we have for study. The caudal pair of these is very long and the latero-caudal pair deli- cate. Pupa case (fig. 3).—Size 0.752 by 0.482 mm. Shape similar to that of floccosus; dorsum not arched, but vasiform orifice slightly elevated. Submarginal area with at least eight pairs of prominent spines, six pairs being situated on the thoracic region and two pairs upon the 7 no. 2156.

Spines latero-cephalad of vasiform orifice and on the middle of the dorsum, as well as the caudal pair of the case, very long; vasiform orifice (fig. 7) as usual and nearly filled by the operculum; margin composed of evenly rounded teeth, though sometimes irregular, some teeth being longer than others.

New Zealand Inst., vol. 28, 1896, p. 432. Aleurodes horridus Hempet, Psyche, vol. 8, 1899, p. 394. Aleurothrixus floccosus QUAINTANCE and Baker, Journ. Agric. Research, vol. 6, 1916, p. 466, fig. 3. In 1895 Maskell described this species from lignumvitae, from Jamaica. Three years later Hempel described his horvidus from Guava from Brazil, and in 1907 the senior author described the woolly white fly of the orange under the name of howardi. Since these descriptions were made we have had an opportunity to study a large series of specimens from different regions and we have also had available Maskell’s type slides of floccosus. There seems little doubt that Maskell’s material and that described by Hempel repre- sent the same species. With howardi, however, there is one point of difference. This is the comb of hair-like projections on the caudal margin of the vasiform orifice of the pupa case. In collections from orange from different regions both types are found side by side upon the same leaf. Some have the comb and some do not. The relation between these two forms, so closely associated, can be shown only by careful rearing experiments and comparison of all stages. In the meantime, therefore, we use the name floccosus for those pupa cases lacking the comb, and howardi for those cases possessing it. Floccosus was first recorded upon orange by T. D. A. Cockerell * from Zapotlan, Mexico, collected by C. H. T. Townsend, July 5, 1902. This is also the first record for Mexico. It is, however, in the bureau collection from Laguna, Mexico, on orange, collected by Townsend, April 24, 1896. Since complete descriptions of the species have been given by the authors mentioned, nothing further will be added here, excepting the records of the color phases. The typical phase and that represented by the types of floccosus and by horridus is the yellow one. All of the pupa cases are a uniform yellow. This phase is by far the most 1 Synopsis of the Aleyrodidae of Mexico, in Mem. y. Riv Soc.

Two lots—one from Jamaica and one from Mexico—show a median dark brown stripe more or less developed. One collection from Brazil, of which the host is unknown, is remarkable in that the thorax of all the pupa cases is yellow, whereas the abdomen is uniform dark brown. This phase is very striking and so far has not been met with in any of the other collections. A fourth phase, and a fairly common one, has the dorsal disk dark brown and the submarginal area, together with the marginal tubes, yellow. It has been received from Florida, Brazil, and Costa Rica. Still another phase has the entire dorsum brown with the exception of the marginal tubes, which are yellow. This has been received from Argentina and Paraguay. A. floccosus is common in the islands of the West Indies and occurs also in Florida, Mexico, British Guiana, Brazil, Argentina, Canal Zone, Chile, and Paraguay. In addition to the orange, lime, grape- fruit, etc., floccosus has been taken on the sea grape (Coccoloba uvifera), Plumeria species, Baccharis genistelloides, guava, a coarse grass, and a climbing vine.

Cockerell, in his Classification of the Aleyrodidae! pub- lished in 1902, established the subgenus Dialewrodes and pointed out several important characteristics of the group. Aleyrodes citri Riley and Howard was indicated as type and A. eugeni# and A. aurantit were also referred to this subgenus. In a subsequent paper, The White Fly (Aleyrodes citrv) and its Allies,? Cockerell cites as additional examples of Dialeurodes, Aley- rodes croceata, A. fodiens, and A. piperis. Some of the species referred to Dialeurodes by Cockerell do not belong to the group, as understood by us—i. e., cotesit, piperis, and croceata. The writers believe that Dialeurodes is of generic rank and have so indicated. While the species of Dialewrodes present a general uniformity im the presence of certain prominent characters, there are to be recognized several minor groups for which it has seemed necessary to erect subgenera. Species of this genus are largely oriental, and some of them are of especial interest by reason of their injuries to plants, as D. citri, citrifolir, etc. Pupa case variable in size, elliptic to subcircular in outline; color usually yellowish, varying in some species to brownish; margin of case toothed, the wax tubes irregular in outline and but little devel- oped; submarginal area not separated from dorsal disk; dorsum usually without papillae or pores; tracheal folds evident, in some species very conspicuous, terminating on margin of case in a pore, the folds often showing dot-like, linear, or polygonal markings; wax secretions absent or very scant.

In regard to the position of the species fodiens Maskell, which is placed in the subgenus Dialeurodes, some statement is necessary. We know the species only from the one specimen in the Maskell collec- tion, which is in rather poor condition. Two possibilities occur: First, it may not be a normal specimen of the species, and, second, it may not be the final pupal stage. In the specimen the tracheal thoracic folds and pores are hardly suggested. Since all other species similar to it show these characters very distinctly, the possibility of 408 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 51. } the abnormality of the individual becomes greater. It seems wisest, therefore, to leave it in Dialeurodes until more material comes to hand for study. The species tricolor, placed in this subgenus, also deserves mention. It is scarcely a typical Dialewrodes and possibly may represent a dis- tinct subgenus; nevertheless, on account of the structure of the orifice and nature of the pores of the thoracic folds it is left here for the present.

Later a more complete and detailed description was given by Riley and Howard, and these authors have since been credited with the name. According to the rules of zoological nomenclature, however, Ashmead is to be considered as author of the species. In the same year that Riley and Howard’s description appeared, H. A. Morgan published the description of another species on orange under the name citrifoli. This species was later confused with Ashmead’s species. In 1896 Maskell published his description of awrantii, placing it as a variety of his eugeniae. As pointed out by the senior author, however, no difference can be noted between the specimens of aurantit in the Maskell collection and specimens of citri; and, subsequently, citri has been collected from numerous localities in India, the home of Maskell’s aurantit. In the Florida Agricultural Experiment Station Bulletin 67 Cockerell raised aurantiw to specific rank, and further expressed the opinion that the home of citri would probably be shown to be in the Orient. This has been fully substantiated by the collec- tions of Messrs. Ehrhorn, Karnes, and Woglum. The specimens from which the original description of citri was made were probably secured from orange in Washington, District of Columbia, though specimens had previously been collected in several localities in the Gulf States. The species is now represented in the collection of the bureau from the following States in the United States: Alabama, California, Colorado, Florida, Illinois, Louisiana, Mississippi, North Carolina, Texas, and District of Columbia. The occurrence of the insect in Colorado, Illinois, and the District of Columbia is probably confined to conserva- tories. Specimens have been received from foreign countries as follows: India (Lahore; Gujranwala; Dehra Dun; Wazirabad; Am- s * No. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE &€ BAKER. 409 ritsar; Khasia Hills; Assam; Saharanpur); Japan (Nagasaki); China (Canton; Pekin; Shanghai). It is stated, on good authority, to occur in Chile; Mexico and Brazil are also given for the species by G. W. Kirkaldy. In the original description of the first larval stage 38 marginal bristles are given. This seems evidently due to the fact that the margin possesses a series of small! tubercles, some of which possess spines and some of which do not. The Riley and Howard slides of this instar show the correct number of spines for citri, but it was evidently supposed by those gentlemen that the tubercles not pos- sessing spines had lost them and thus the full number of spines was described and figured. This fact led Morrill and Back to conclude that Riley and Howard’s description was based on specimens of citrifolia (nubifera), for they remark: “In the text the description of the first stage or instar of the larva was evidently based on a specimen of the spotted winged white fly and the illustration of the first instar was also based on the species with little doubt.” Egg (pl. 63, fig. 9).—The eggs are placed irregularly upon the under surface of the leaf and are greenish yellow in color, either polished or pruinose, due to the deposition of mealy wax by the adults. The surface is without the reticulate covering observed on the eggs of citrifolit Morgan. The stalk is situated at the larger end of the egg and is about as long as the egg is wide.

In hatching the egg splits almost its entire length and the two halves of the empty shell do not remain widely apart, as is the case with the eggs of citrifoliv. Larva, first instar —Color light yellowish, with sometimes orange areas in the abdomen showing through; eyespots dark brown; shape oval, broadest across the anterior abdominal segments, flat upon the leaf. There is no lateral or dorsal secretion. Size 0.32 by 0.2 mm. Margin entire, armed with 17 small tubercles on each side, 14 of these bearing bristlelike hairs, as shown in figure 6, while 3 do not have these hairs. On the cephalic extremity there is another pair of short hairs situated somewhat ventrad of the margin. This makes in all a row of 30 hairs encircling the margin. Of these the second cephalic pair and the first and third caudal pairs are long, the others short. Antennae (pl. 63, fig. 8) of three segments, the third being lashlike and showing two angled spurlike portions, one at the extremity and one about a quarter of the way from the distal end. Legs (pl. 63, fig. 7) with a swollen portion at the distal extremity, the median seg- ment and the proximal one each armed with a long curved spine.

Margin with minute irreg- | ular incisions and devoid of all hairs or bristles excepting a cephalo- lateral pair, one large caudal pair, and a smaller caudo-lateral pair. There is a slight constriction in the region corresponding to the tra- cheal pores of the pupa case, and sometimes there are a number of regular toothlike projections therein. The vasiform orifice is rounded cordate, the operculum similar in shape, with the exception that the lateral margins are somewhat constricted. The lingula is not visible. The dorsum is covered with numerous granular markings. Third instar—Color similar to that of the second instar; shape oval; size 0.59 by 0.432 mm. Margin with minute indentations and with three pairs of bristle-like hairs similar to those of the second instar. In this instar the three tracheal folds are evident and are marked within with a large number of minute circular transparent areas similar to those present in the folds of the pupa case. The vasiform orifice is similar in shape to that of the second instar. Pupa case.—On the leaf the pupa cases are yellowish in color, sometimes slightly brownish. They are devoid of either dorsal or lateral secretion, are lighter toward the margin than on the median dorsal area, and the entire case when in certain lights often shows very beautiful hues and iridescent colors. The cases are placed upon the leaf without any definite arrangement as to the veins, but are nearly always situated on the under surface. There is a very nar- row, acute, dorsal keel extending down the middle of the thorax and joining the transverse suture, which divides it from the abdomen. On the central dorsal area, that part immediately above the body of the developing adult, the segments of the body are distinctly marked, somewhat rounded, and the entire surface perfectly smooth and highly polished. The lateral area of the dorsal disk, however, is very minutely and irregularly striate, in some cases giving almost the appearance of minute punctures. The thoracic tracheal breath- ing folds are raised above the surrounding area, and the opereulum and caudal tracheal areas are usually slightly elevated. On the submarginal area the striations which show considerable irregularity on the dorsal area become more even, extending in from the margin. The marginal area is somewhat rounded, being curved downward slightly to meet the margin, which is considerably nearer the leaf than the highest point of the case. In some specimens the median area of the case collapses as the insect within dies, owing to drying upon the leaf. These are generally paler in color than those which have not shrunken. Under the microscope (pl. 64, fig. 1) the color is pale yellowish, almost transparent on the margins and often somewhat darker on the median area, owing to the color of the viscera. In shape the case is subelliptical, tending toward oval in some specimens, and often *. No. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 411 slightly constricted just caudad of the thoracic tracheal pores. Average length of case 1.52 mm. The margin (pl. 63, fig. 3) is armed with a series of minute tooth-like divisions from which suture-like markings extend mesad on the case. These markings are not of equal length, but usually every third one extends farther mesad than the others, giving the effect of a double series—a longer and a shorter one. The submarginal area, with the exception of that portion very close to the margin itself, is similar in structure to the dorsal disk. The sutures are evident upon the dorsum, but not strongly marked in mounted specimens. There are no dorsal spines. The tracheal folds (pl. 63, fig. 2) are prominent, their pores being situated either on the margin or very close to it. The ring of the pore is not armed with fimbriz, or teeth, but is entire. It is, however, covered with series of minute circular markings. The fold itself is without any sculpturing of the dorsal derm, but on focusing down into the case a large number of minute transparent circular areas are visible, as shown in the figure. They are present on both of the thoracic and on the caudal tracheal folds. The vasiform orifice (pl. 63, fig. 4) is almost circular in outline; the inner caudal margin is armed with a varying number of short, acute, irregular teeth. The lingula is not visible, as it is obscured by the operculum. This latter is somewhat semicircular in outline, with the lateral margins constricted and the cephalic margin straight. The color of the orifice is somewhat darker than that of the remainder of the case, with somewhat more of a greenish cast. Adult female.—The female is yellowish and dusted with white pow- dery wax. When at rest the wings are laid back against the sides of the abdomen. ‘The head, which is covered with fine wax, is on this account white, with the exception of the eyes, which are chocolate brown. The basal segments of the antennae are white, pruinose, while the distal ones are usually yellow tinged with pale red. The wings, owing to their waxy covering, are white and opaque, the thorax and abdomen, as viewed from above, amber colored. There are occasionally seen on the thorax small brown markings. When viewed from below the body is yellow or amber colored, more or less dusted with white wax. The legs are sometimes tinged with red and the labium is tipped with dark brown. Under the microscope the color is yellow, with the eyes dark brown and the ocelli dusky. Length from vertex to tip of ovipositor 1.36 mm. The forewing (pl. 63, fig. 11) is 1.408 by 0.64 mm., clear transparent without any shading or marking; radial sector slightly curved and extending almost to the margin. Cubitus fine, but long and distinct; media rarely rep- resented by a faint shading near the base of the radial sector; remnant of the vein as in species of Aleyrodes.

Proximal segment — of hind tarsus armed with two longitudinal rows of spines, one com- posed of four spines and one of five spines. Other smaller hairs are present and a thicker spine is present on, its distal extremity; length 0.16 mm. Distal segment armed with four spines; length 0.042 mm. Foot (pl. 63, fig. 12) with a central hairy paronychium and short curved claws. Antennae of seven segments (pl. 63, fig. 10). Segment II subpyriform, 0.06 mm. long, armed on its distal extremity with three or four prominent spines and numerous smaller hairs. Segment IIT subcylindric, tapering proximad and distad; the proximal half pos- sesses imbrications, the distal half has usually six prominent trans- verse annular sensoria, and one distal circular fringed sensorium; length 0.114 mm. Segment IV 0.042 mm., subcylindric and armed with three or four transverse sensoria. Segment V 0.045 mm., sub- cylindric, and with usually four transverse sensoria. These are very fine and not prominent, as upon the other segments. Segment VI 0.054 mm., subcylindric, with four rather prominent transverse sensoria. Segment VII 0.06 mm., subcylindric, rather narrower than the other segments and armed with three or four transverse sensoria and two or three minute circular fringed ones; distal ex tremity tipped with a prominent bristle. Adult male.—Similar to the female in general appearance, but smaller. Length from vertex to tip of claspers 1.28 mm. Antennae similar to those of the female. Segment II 0.054 mm.; III 0.111 mm., with usually six transverse sensoria; [TV 0.045 mm., with about four transverse sensoria; segment V 0.045 mm., with three or four transverse sensoria; segment VI 0.051 mm., with five or six transverse sensoria; segment VII 0.06 mm., with four or five sensoria. Hind tibia 0.368 mm. long; hind tarsus 0.128 mm. for the proximal seg- ment, and distal 0.08 mm. long. Claspers (pl. 63,fig. 13) 0.102 mm. from the distal extremity to the shoulder, and 0.084 mm. across to the shoulder, tapering, upcurved, and armed each with three large spines and a series of smaller hairs on its inner distal margin. Penis nearly as long as the claspers, tapering and upcurved at the tip, and bulbous at the base. Length of forewing 1.¢6 mm. DIALEURODES (DIALEURODES) CITRIFOLIT (Morgan). Plate 65, figs. 1-14.

The species described and figured by Morgan is easily separated from citri, redescribed by Riley and Howard in the same year, by the characters of the egg, pupa case, and of the adult. The egg in *» No.2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 413 particular easily separates the two species, and this stage was well described and figured by Morgan. It seems unnecessary, therefore, to discard Morgan’s name for nubifera, which was proposed by Berger in 1909. In proposing this name Dr. Berger says ‘‘the reticulate egg was figured in 1893 by H. A. Morgan,” but he makes no mention of the fact that descriptions of the pupa case and adults were also given. Morrill and Back in following Berger state that the descrip- tion of the pupa and adult given at the same time were ‘‘evidently * * * based on specimens of A. citri.”” There seems, however, nothing in Morgan’s description which would not be true for ciirifoli, and as the egg definitely fixes the identity of the species, Morgan’s name should be retained. Dialeurodes citrifolii is known from the following States: Florida, California, Louisiana, Mississippi, and North Carolina. No specimens of this species were taken by Mr. R. S. Woglum in the Orient, though it will probably be found to be native to that region. It is also known from Mexico and Cuba. Egg (fig. 9).—The eggs are laid without any definite arrangement upon the under surface of the leaf. The egg is elliptical-elongate in shape, and in hatching the opening does not extend more than half way down the egg. This slit remains open, being different in this respect from the egg of D. citri. In size it is about 0.256 by 0.088 mm., and when first laid it is cream color, later changing to a slate or bluish black. It is pruinose and covered with a waxy coat in the form of hexagonal meshes (fig. 10). This may become dissolved in preparing mounts and is often broken from the egg in the dry state. This waxy covering and the dark color serve easily to separate the ege of citrifolii from that of citri. The stalk is attached to the base of the egg, is pale yellowish in color, and usually about as long as the ege is wide, though in some cases it is much longer. Larva, first instar.—Color light-yellowish green, sometimes whitish, due to slight particles of wax on the ventral surface. At first there is neither lateral nor dorsal secretion, but soon an irregular waxy fringe, as wide as the length of the marginal hairs, is secreted. Shape elliptical; size 0.3 by 0.2 mm.; margin almost entire and armed with 18 pairs of hairlike bristles. Of these the first and third caudal pairs are much longer than the others, as is also the second cephalic pair. The antennae and feet are similar to those of D. citra. Pupa case.—On the leaf the pupa cases are pale yellowish in color, rather white when the adult has emerged, and lack both dorsal and lateral secretion. They are much evener in shape than the cases of D. citri, being elliptical. They are extremely flat and thin and in this respect also differ from citri. In the character of the surface there is little difference between the two species, as citrifoli1 possesses the same almost smooth condition of the median portion of the dorsal disk and the same striations on the submarginal area. The 414 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 51. striations, however, seem to be a little more regular in most speci- mens of citrifolit than in those of citri and light is not so much reflected from the surface. The cases collapse when the adult has emerged. Balsam mounts by transmitted light show the cases yellowish in color, almost transparent; size 1.76 by 1.32 mm. (fig. 1). The margin (fig. 12) is very minutely serrate, and extending inward from it is a closely set series of narrow pointed wax tubes, which broaden as they extend mesad and collectively form a marginal band all around. The dorsal derm is closely set with irregular more or less circular markings which seem to be arranged more or less concentrically from the me- dian dorsal area to the margin. On the submarginal area the thoracic and caudal tracheal folds are distinct, the openings of the thoracic pair (fig. 2) being near the margin and armed with six or eight rather distinct fimbriae. The caudal fold (fig. 3) is marked with numerous large and small irregular reticulations with differentiated centers. These are much larger and more irregular in size than the minute dots present within the folds of D. ciiri. The thoracic tracheal folds seem to lack these markings. The vasiform orifice (fig. 4) is subcordate, 0.051 mm. wide, and 0.048 mm. long. The inner caudal margin is armed with a rather large number of fairly distinct teeth directed cephalad; operculum similar in shape, with the anterior margin straight and the sides slightly compressed. It almost entirely fills the orifice. On each side of the vasiform orifice a minute seta is situated and a pair is present on the latero-caudal and cephalic margin. Adult female.—Color very similar to that of D. citri, with the excep- tion of a dusky spot on the distal extremity of the forewing, this being one of the characteristics by means of which it is easily dis- tinguished. Length from vertex to tip of ovipositor 1.28 mm.; color in balsam mounts yellow, shaded with brown; forewing when mounted almost transparent with the exception of the shaded area before mentioned; venation similar to that of citri; size of the fore- wing 1.2 by 0.64 mm.; legs yellow in color; hind femora 0.304 mm.; hind tibia 0.432 mm.; armed with a longitudinal row of about 12 spines, with another row of similar spines placed about the same distance apart as those of the first row, and with still a third row of smaller spines placed very close together. Hind tarsus with the proximal segment 0.126 mm. long and armed with a longitudinal row of four spines, of which the distal one is the largest (fig. 13). Foot with claws not greatly curved and with the paronychium rather broad (fig. 14). Antennae (fig. 5) of seven segments. Segment I subglobose; II subpyriform, 0.06 mm. long and armed with a few prominent spines; III subcylindric, somewhat tapering distad and proximad, 0.126 mm. long, armed with 25 or 30 very fine annular sensoria, and near 1 * no. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCEH & BAKER. 415 the distal extremity with two circular sensoria. These last (fig. 6) are composed of a central thumb-iike process surrounded by a ring on which three or four stout bristles are situated. Somewhat prox- imad of these two sensoria is a rather long but not easily distinguished spine. Segment IV 0.021 mm. long, subcylindric, and armed with four or five fine transverse sensoria; segment V subcylindric, about 0.036 mm. long and armed with seven or eight transverse sensoria and a distal circular sensorium. Segment VI subcylindric, about 0.03 mm. long, armed with six or seven transverse sensoria, and at about its middle with a long spine. Segment VII 0.057 mm. long, tapering considerably distad, and armed on its proximal portion with a num- ber of faint transverse sensoria. On the basal third there is situated a long spine, and the distal extremity is tipped with a very prominent spine measuring 0.027 mm. in length; the long spines arming the segments, with the exception of the distal spine, are very difficult to see in some specimens and in some do not appear to be present at all. The antennae of the adult are considerably different from those of citri—first, as regards the length of the respective segments; secondly, the sensoria are much more numerous and smaller; and thirdly, the distal spine is about as long as in eitrifolit. Adult male.—Similar to the female in general appearance, but somewhat smaller; length from vertex to tip of claspers from 0.88 to 1.04 mm.; forewing, length 0.96 mm.; hind tibiae 0.336 mm.; hind tarsus, proximal segment 0.112 mm., distal segment 0.08 mm. The claspers (fig. 8) are about 0.12 mm. long, and 0.075 mm. broad at the shoulder. They are tapering, upcurved, and armed with a few spines and hairs. The penis is about as long as the claspers, is curved dorsad, bulbous at the base, and narrowed distad. DIALEURODES (DIALEURODES) FODIENS (Maskell). Plate 66, figs. 1-4. Aleurodes fodiens Maske, Trans. N. Zealand Inst., vol. 28, 1896, p. 433. Pupa case (fig. 1).—The pupa case of this species is the smallest in the genus thus far known, measuring only 0.8 by 0.72 mm.; the margin is entire, though faint sutures are evident, extending mesad through a narrow, evident submarginal area. There are no distinct caudal or thoracic tracheal folds or pores, and in this regard it differs from the other species. The remaining characters and general appearance, however, undoubtedly place it here. The tho- racic and abdominal segments are plainly marked off by light yellow sutures on a median dark brown area; derm of dorsal disk shagreened; the remaining portion of the case is yellow to almost transparent; the eyespots are large, granular, and purple in color; the vasiform orifice (fig. 2) is elongate cordate; the rim thick and the cephalic 416 PROCEEDINGS OF THE NATIONAL MUSEUM. vou.51, | margin slightly curved caudad. The caudal and lateral margins — inside are armed with a number of short, acute fimbriae; the lower inner lining of the orifice is coarsely reticulate, giving it an irregular serrate appearance. The operculum is semicircular or slightly cres- cent shaped, and about half fills the orifice, obscuring the lingula, which is setose and armed with two fine bristles (fig. 3).

Paratypes of this species are in the bureau collection and consist of eggs, larvae, and pupa cases. We have also for study specimens of pupa cases and adults taken by Mr. G. E. Bodkin, on leaves of jasmine, Georgetown, Demerara, British Guiana, February, 1912. Egg.—Size about 0.178 mm. long by about 0.096 mm. wide a short distance from the unstalked end, narrower at the stalked end; color yellowish. In hatching the egg splits downward for 0.09 mm. and spreads open considerably; surface without sculpturing; stalk at- tached near the middle. Larva, first instar (pl. 67, fig. 11).—Size 0.24 by 0.16 mm.; regularly elliptical; color light yellow, with dark brown eyespots. There are on the margin of the specimens at hand 14 pairs of hairs, the po- sition of which is best shown in the figure. It will be noted that there are a number of marginal papillae on which no hairs are shown, while in one of our specimens there are no hairs on any of the papillae of the cephalic half. This absence of hairs from some tubercles may be due to imperfect specimens, but this occurs in citri Ashmead, where it is normal. Pupa case (pl. 67, fig. 1)—Much resembles citri; size about 1.84 by 0.846 mm.; many of the cases, however, are smaller than the above dimensions; shape elliptical, with slight indentations on margin at the pores of the tracheal folds; form flat, thoracic sutures plainly visible as transparent lines on the dark brown median area; abdom- inal segments not distinct. Color transparent or yellowish, with a median brown longitudinal area. This sometimes occurs only on the thorax, and again it extends caudad to the vasiform orifice. Tracheal folds (pl. 67, fig. 3) marked with minute dots, the pore located near the margin and being without fimbriae, though with a distinct rim. Vasiform orifice (pl. 67, fig. 2) cordate, somewhat rounded, with the cephalic margin straight. The caudal margin is armed with 25 or 30 rather well-defined fimbriae or teeth; size of orifice 0.039 by 0.039 mm. — no. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 417 The operculum is of very much the same shape as the orifice, but indented on the lateral margins. It almost fills the orifice and obscures the lingula, which is spatulate. On either side of the vasi- form orifice a small seta is situated. Margin of case marked by a large number of closely appressed sections formed by the sutures of wax tubes. Adult male—Length from vertex to tip of claspers 0.85 mm.; color yellowish, with a slight tinge of brown on the thorax; ocelli dusky; eyes dark brown, almost black; vertex rounded; antennae (fig. 10) of seven segments.

Legs almost transparent; distal extremity of the hind tibia armed with two prominent spines on its inner edge; proximal segment of tarsus armed on its distal extremity with a large spine (pl. 67, fig.9). Five other spines, somewhat shorter, are present on the median portion of the segment in two rows, one row of two spines and one row of three; distal segment of tarsus with three prominent spines on its inner margin, and also a large number of fine hairs; proximal segment of hind tarsus 0.088 mm. ; distal segment 0.06 mm.; foot 0.015 mm. (pl. 67, fig. 8), with a median hairy paronychium. Forewing (pl. 67, fig. 6) 0.72 mm. long and 0.24 mm. wide; radial sector bent very slightly in its median part and extending almost to the distal margin; media sometimes faintly indi- cated by a shading, but usually this is not evident; cubitus fine and distinct, rather long and in the usual position; margin of wings with a series of bead-like structures, on which hairs are situated; color clear without spots or shading; claspers (pl. 67, fig. 7) 0.1 mm. long and 0.06 mm. broad at shoulder, tapering, upcurved, acute at the distal extremity, and armed with about five spines on each. Penis elon- gate, acute, and upcurved distally, bulbous at the base. The testes may be seen through the abdomen as orange-yellow masses com- posed of globular-like bodies.

Length from vertex to tip of ovipositor 1.12 mm.; forewing 1.28 mm. by 0.56 mm.; hind tibiae 0.432 mm.; proximal segment of tar- sus armed with two longitudinal rows of stout spines, of which the distal one of the rows is especially stout. There are also on the seg- ment, particularly on the distal part, a large number of fine hairs. The distal segment is armed with two pairs of stout spines and numer- ous fine hairs; claws not strongly curved; paronychium long, acute, and hairy; vertex rounded. Antennae of seven segments, the first subcylindric, short, and thick; second subpyriform; third and dis- tal ones subcylindric and armed with annular sensoria. These are more prominent on segments VI and VII than on the others. Seg- ments III and VII are each also armed distad with a circular, fringed sensorium, and VII is tipped with a bristle. Length of segments as follows: I 0.021 mm.; II 0.048 mm.; III 0.105 mm.; IV 0.015 mm.; V 0.024 mm.; VI 0.045 mm.; VII 0.06 mm. The radial sec- tor is prominent in the forewing and curved on its distal part, while the cubitus is faintly represented; the margin of wings is armed with knob-like projections on which minute hairs are situated. The ovi- positor is acute, distinctly three-cleft, and dark in color. It is armed with stout spines, the distal ones of which are long, extending almost to the tip of the ovipositor itself.

Foliage of a myrtaceous plant infested with this insect and collected at Eubato, Brazil, was received by the Bureau of Entomology in July, 1898, from Dr. F. Noack. A balsam slide mount contaiming five pupae is all of this material which we now have. The species, however, is quite distinct and is easily recognizable. Pupa case (fig. 8).—Under reflected light the case appears brown- ish in color and is apparently void of waxy secretion. Examined under the microscope, the coloring is found to be about as follows: All around margin is a rather narrow border, the inner margin showing an interrupted line of pale yellow. The submarginal area is lemon yellow and the dorsal disk orange in color. Surrounding the dorsal disk is an irregular band of dark brown covering the vasiform orifice and extending cephalad to the transparent marginal rim, where it spreads out, forming a broad arrow-shaped figure (fig. 8). The shape is subcircular, margin flattened, and dorsum somewhat con- vex; size 1.28 by 1.088 mm. Margin (fig. 9) minutely incised; the sutures between wax tubes are quite distinct, extending mesad to the yellow subdorsal area. Derm thickly marked with granular spots, very evident under reflected light. Transparent marginal area with rather numerous, large, more or less circular markings. This rim is very generally sprinkled with minute lighter colored dots. On inner margin of transparent marginal rim is an interrupted row all around covered by rather prominent subcircular brown spots. Thor- acic segments distinct; abdominal segments moderately so. Tra- cheal folds evident toward margin of case, ending just within margin in the transparent rim or band. The pore (fig. 10) is bordered all around with brownish. There appear to be no fimbriae or teeth around pore orifice, but the derm is marked with closely set radiating lines. 420 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 51.

This species is represented by one pupa case in balsam mount in the Maskell collection. It is in rather poor condition, being more or less covered with a fungous growth. Pupa case (fig. 1).—Size 1.38 by 1.04 mm. Outline regularly elliptical; median dorsal area dark brown, on which the prominent thoracic sutures show clearly transparent. The abdominal sutures are not so distinct. The tracheal folds (fig. 3) show very promi- nently owing to a reticulate sculpturing with which they are covered. The pores (fig. 2) are situated some distance in from the margin and are armed with about 16 rather distinct teeth. The fold is delineated by fine ridges, which border the sculptured area and encircle the outer margin of the pore. The vasiform orifice (fig. 4) is subcordate in outline, with the cephalic margin but little rounded. The inner margin of the orifice is devoid of teeth common to citri and citrifolii. The operculum is of much the same shape as the orifice and nearly fills it. The tip of the setose lngula appears to protrude below the caudal margin of the operculum for some distance, but this may be due to the preparation of the mount. The marginal area of case is marked by sutures running a considerable distance mesad, forming a zone all around case, about one-third diameter of case. Adulis —Unknown. Habitait.—India, on Eugenia jambolana. DIALEURODES (RUSOSTIGMA) RADIIRUGOSA, new species. Plate 69, figs. 1-9. This species is represented by two lots of material. One lot was taken on mango by R. 8S. Woglum, Brilliton Isle, Dutch East Indies, February 5, 1911, and the other was taken on a “woody shrub” by C. L. Marlatt at Gerolt, Java, December 7, 1901. The material in both cases is composed of pupa cases only. The species suggests eugeniae, owing to the distinct reticulate areas of the tracheal folds. It is readily distinguished from this species, however, by the extent of the reticulate area, and the unsculptured, circular area immediately surrounding the marginal pore. Egg.—Short, ovate, with short stalk, the eggs being held upright on leaf; color dark brown, apparently without reticulation. Pupa case (fig. 6).—As seen on leaf the color is dirty white or yellowish. The dorsal disk is but little elevated, and the submar- ginal area is rather clearly delineated as a radiate band all around, this appearance resulting from the sutures of the wax tubes. The case is void of any waxy secretion; under the microscope the color 422 PROCEEDINGS OF THE NATIONAL MUSEUM. Vou. 61. is yellowish, or nearly colorless, with brownish shading over the tracheal pores; shape elliptical to subcircular; size 1.6 by 1.4 mm. (Parasitized specimens are of quite a different color, being more or less shaded with dark brown on the dorsal disk. This is often very dark and extends almost to the cephalic extremity of the case.) The dorsum is very slightly elevated, but more so in parasitized indi- viduals, and the abdominal segments are quite distinct. The thoracic and caudal tracheal folds are very distinct; the pore itself (fig. 8) is situated a short distance mesad of the margin, and is armed with seven or eight rounded processes. Surrounding these is a clear area without sculpturing and inclosed by a distinct ring. Outside of this ring, surrounding it and extending for a considerable distance mesad, is a series of dark sculptured areas, irregular in size and shape. The band of these sculptures extending from the caudal breathing fold reaches the vasiform orifice and extends around on both sides, though the markings are not present cephalad of it. The bands extending from the thoracic breathing folds are crossed by similar longitudinal ones on the outer margin of the dorsal disk. The entire dorsum excepting the extreme central portion of the dorsal disk is covered with faint irregular coarse sculpturing (fig. 9). The vasiform orifice (fig. 7) is somewhat rounded cordate, with the cephalic margin straight. Entad of the lateral and caudal portion of rim the surface is minutely spinose. The operculum is similar in shape to the orifice and almost completely fills it, leaving the extreme setose tip of the lingula exposed. The margin of case is almost entire, being marked with minute indentations between wax tubes, the sutures extending mesad as faint markings, which gradually merge into the faint dorsal sculpturing above mentioned. Adult female.—Color light brownish, darker on the thorax and on dorsum of abdomen. ‘There is a dark circular marking around the vasiform orifice. The legs are brown. We are unable to give the length of the insects, as the specimens we have are shrunken and broken. The antennae, too, are either absent or so shrunken in the specimens at hand that no description can be given. Forewing (fig. 1) 1.54 by 0.80 mm., covered thickly with white meal-like powder and appearing rather bluish in color. When mounted and examined under the microscope the wing appears rather uniformly brown or smoky in color. The radial sector is thick and irregular, and on its proximal portion and in about the middle two circular sensoria (fig. 2) are noticed. Each of these is surrounded by a clear irregular trans- parent area. Toward the distal extremity the radial sector is strongly curved. There is a clear, unshaded, narrow band which seems to represent the cubitus and another shorter line of a similar nature. Although the body of the wing is uniform smoky, there are a number of darker areas represented. These are generally situated | | . | ~~ no. 2156.

The margin (fig. 3) is armed with a large number of toothlike projections armed with hairs. The hind wing (fig. 4) is similar in color but more uniform than the forewing. The vein is armed with one or some- times two sensoria similar to those in the radial sector of the fore- wing. The proximal portion of the costal margin is armed with a series of stout hairlike spines situated on small tubercles. These are in two series—one on the outer and one on the inner portion of the vein. The vasiform orifice (fig. 5) is somewhat cordate in shape, with the anterior margin straight.

Entom., vol. 3, 1911, p. 622. Egg.—Short, stout, smoky brown in color, and without reticula- tions; stalk quite short, holding egg on leaf in upright position. Pupa case (fig. 6).—Size 1.52 by 1.28 mm.; outline almost entire, with slight indentures at the pores of tracheal folds; dorsum slightly rounded, with the sutures not very distinct; color trans- parent, slightly yellowish. The dorsal disk is granular, being covered with a series of small polygonal markings which graduate on submarginal area into more or less concentrically arranged, but disconnected, thickenings in the derm, the individual thickenings showing one or two acute incisions, as shown in figure 7. Tracheal pores covered with irregular markings quite similar to those found in eugeniae, but they are much more numerous toward the pores (fig. 8), which are surrounded very thickly by them. In the thor- acic folds the sculptured area does not extend so far mesad as in the caudal fold, where it reaches the vasiform orifice and partially surrounds it. The pore of each fold is small and irregular and there are no distinct processes, though blunt, tooth-like projections are sometimes noticeable. The vasiform orifice (fig. 9) is subcordate in outline, with the anterior margin straight. The caudal inner margin is devoid of teeth, but is covered with a series of fine hairs. The operculum is somewhat the same shape as the orifice, though with straighter sides. It nearly altogether covers the lingula, only the tip of which protrudes from below it; both the lingula and the caudal portion of the operculum are setose. The margin is minutely ser- rate, but it is marked by a large number of ridges or sutures extend- ing irregularly mesad, so that in some specimens there appears to be a marginal rim. 494 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 51. Host.—lIlex wntegra Thunberg, and the locality Shibuya, Tokyo. The above description is based on a study of paratype material kindly furnished by Mr. Kuwana. DIALEURONOMADA, new subgenus. In some characters the type-species is related to those of the sub- genus Rachisphora, and in others related to the typical Dialeurodes. So far as our present knowledge goes it is the only example of this type. Pupa case elliptic or oval, pale yellowish white in color, with visible visceral markings of bright red-orange or bright yellow; marginal wax tubes evident as distinct, but shallow, irregular tooth- like divisions of the margin, the sutures between which extend a considerable distance mesad; dorsal disk without sculpturing, but near its margin all around one or more rows of moderate sized pores; no rachis present, and on submarginal area no series of large pores; margin all around armed with a series of spines; thoracic tracheal folds distinct, either unsculptured or covered with minute dots; the pore armed within with usual lobe-like projections; vasiform orifice very broadly subcordate, almost semicircular, its inner caudal and lateral margin armed with prominent teeth; operculum almost entirely filling orifice. Type.—Draleurodes (Dialeuronomada) dissimilis Quaintance and Baker. DIALEURODES (DIALEURONOMADA) DISSIMILIS, new species. Plate 70, figs. 1-4. This species was collected by R. S. Woglum on Phyllanthus myrti- folium at Saharanpur, India, November, 1910. It is represented in the Bureau of Entomology collection by pupa cases only. Pupa case (fig. 1).—Size 0.98 by 0.66 mm.; shape oval, with considerable constriction along sides of thorax, and broadened across the cephalic abdominal segments; form flat. On the leaf only a few specimens are available for study. They lack either dorsal or lateral secretion and are white or grayish in appearance. Under the microscope the cases which are empty are transparent; those, however, which contain the pupa are pale yellowish, with a large irregular central dorsal patch of bright red. A number of circular or oval areas, varying in size, some transparent and others not, are present in this red area. The margin of case (fig. 3) is com- posed of a series of closely placed wax tubes, from which there extend mesad suture-like markings on the derm. Some of these, on the average every third, extend much farther mesad than the others, in this respect resembling considerably those of citri Ashmead. A series of 12 spine-like hairs is present on each side of the case. ! | | | ' * No. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 425 The suture separating the abdomen from the thorax is not distinct in all specimens and the thorax is remarkable in being of about the same length as the abdomen. On the outer margin of the dorsal disk, extending all around the case, there is a ring composed of one or two rows of papilla-like pores (fig. 1). The vasiform orifice (fig. 2) is considerably broader than long, measuring the orifice proper, but the outer margin of the orifice extends cephalad, making the depth of the entire structure almost equal to the width. The inner lateral and caudal margin of the orifice is armed with usually 16 prominent rounded fimbriae, or teeth. The cephalic margin of the orifice proper is straight; the operculum almost entirely fills the orifice, being somewhat triangular in shape. The tracheal pore (fig. 4) has no distinct fimbriae, but has an irregular rim. The fold is marked with a number of suture-like markings extending mesad, and a large number of dots similar to those on the folds of citri are visible. These, however, are not upon the dorsal derm of the fold, but on the ventral portion as seen by focussing through. The species can be easily distinguished from others in the genus by the marginal hairs, the ring of papilla-like pores on the border of the dorsal disk, and by the large bright red dorsal marking. Adulis —Unknown. Type.—Cat. No. 19052, U.S.N.M. RABDOSTIGMA, new subgenus. Somewhat related to the subgenus Rusostigma is the species radii- linealis from Ceylon. This species is as yet the only example of this type, wherein the polygonal areas of the tracheal fold, as shown in the species of Rusostigma, are replaced by linear thickened lines. Pupa case.—Subcircular, usually yellowish, margin almost entire, the wax tubes being merely portions of the margin which are sepa- rated by sutures extending mesad; waxy secretion usually absent; dorsal disk without sculpturing or large pores and with no develop- ment of a rhachis; thoracic tracheal fold ending near the margin in a pore which is armed within with several teeth; fold marked with thickened linear lines; vasiform orifice roundly subcordate to sub- circular; comb of teeth absent; operculum similar in shape and almost entirely obscuring the lingula. Type.—Dialeurodes (Rabdostigma) radvilinealis Quaintance and Baker. DIALEURODES (RABDOSTIGMA) RADILINEALIS, new species. Plate 70, figs. 5-8. This form is represented in the Bureau of Entomology collection by the pupa case only, which was taken by Mr. C. L. Marlatt, on mistletoe, at New Ava Eliya, Ceylon, January 26, 1902. The species 426 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 51. is quite distinct by the presence on the tracheal folds of long, linear thickenings of the derm. The immature stages make pits on the lower surface of the leaf, resembling in this way fodiens and some psyllds. Pupa case (fig. 5).—Size 1.76 by 1.6 mm.; outline almost circular, form flat; color in normal specimens almost transparent, but in parasitized individuals there are often two brown areas, extending over the thorax and abdomen on each side of the median area, which latter is pale transparent yellowish white, ike the submarginal area. The suture separating the thorax and abdomen is very distinct and transparent. It does not extend to the margin, but curves cephalad and joins two somewhat similar transverse sutures, the three all being very prominent and inclosing two elongate transverse areas. The abdominal segments are not distinctly marked off. The tracheal folds (fig. 6) are easily distinguished, and are marked by a series of fine longitudinal ridges. The pore is situated a slight distance in from the margin of case, and is armed with eight or nine rather dis- tinct projections. The ridges which mark the fold encircle this open- ing on its outer edge, but leave a small, smooth area mesad of it. The vasiform orifice (fig. 7) is subcordate in outline, tending to cir- cular; the cephalic margin is almost straight and the inner caudal margin is without the fine teeth. The operculum is similar in shape to the vasiform orifice, but the sides are compressed. It almost entirely fills the orifice and almost altogether obscures the lingula. The margin (fig. 8) is entire, but the marginal area is marked off by a series of fine sutures extending mesad. Type.—Cat. No. 19053, U.S.N.M. GIGALEURODES, new subgenus. Related to subgenus Rabdostigma in several characters is a small group of species for which is erected the above-named subgenus. Two of the largest known species of the subfamily belong here.

DIALEURODES (GIGALEURODES) CERIFERA, new species. Plate 71, figs. 1-4. This species was received by the Bureau of Entomology April 10, 1901, from Mr. C. W. Mally, Cape Town, South Africa. The host is Celastrus buaifolius. Egg.—Length 0.24 mm., elongate, curved; stalk shorter than width of egg at point of attachment: dirty white to brownish in color; surface densely covered with minute sculpturing. Pupa case (fig. 1).—As seen on leaf the pupa case is yellowish brown, with dorsal disk dark brown, and is quite conspicuous in contrast with the light-colored lower surface of the leaf of the host plant. There is a fringe all around of glossy wax rods from marginal wax tubes, compact basally, but the rods separating distally. On numerous specimens this fringe is absent, having apparently weathered off. The dorsum is without secretion. The case is flattish and closely applied to leaf, there being no vertical wax fringe; dorsum slightly raised. This species, Thomen plainly of the citri type, differs in the development of the marginal wax tubes and the presence of the fringe of wax rods. Under the microscope the dorsal disk is brown in color, the balance of case being rather uniformly yellow; the shape is paoddiy elliptical to subcircular; size 1.6 by 1.3 mm.; margin of case beaded by the distinct and functional wax tubes; the incisions shallow and acute. Thoracic and caudal tracheal folds fairly evident, the latter fur- 498 PROCEEDINGS OF THE NATIONAL MUSEUM. von. 51. rowed. The pores of these folds open close to margin and have the 7 appearance shown in figure 2. There are no dorsal wax pores, but — on each side of median line of each abdominal segment are a few clear — white dots. From the region of the dorsal disk to the periphery a — radiate pattern is evident, due to the mesal extension of the marginal wax tubes. Vasiform orifice (fig. 3) subcordate in outline, the cephalic margin straight. The caudal rim is without teeth or fimbriae as are present in citri.

DIALEURODES (GIGALEURODES) BUSCKI, new species. Plate 71, figs. 5-12. Several leaves infested with this species were collected by Mr. August Busck, January 15, 1899, at Bayamon, Porto Rico. The host plant is stated as ‘‘a climbing vine.” The immature stages occur on both surfaces of the leaf. Pupa case (fig. 5).—The insect in this stage much resembles in general appearance citri. Many of the individuals, however, have the dorsal disk dark brown. However, this character appears not to be constant, as many colorless specimens are to be found from which the adults have emerged. There is no waxy secretion evident. As observed under hand lens, the dorsum is seen to be much wrinkled by the body sutures and the submarginal area is’ marked with fine radiating lines extending from dorsal disk all around to margin of case. The margin is marked with many minute, acute incisions between the wax tubes, the sutures between which are more or less evident well toward the dorsal disk and give the radial appearance noted under the hand lens. All around margin there is a narrow and not well delineated light-colored band. Many apparently normal individuals have the dorsal disk brown in color, and there are gradations from this condition to individuals colorless throughout; the shape is oval and flattened, broadest across the second and third abdominal seg- ments; size about 1.59 by 1.28 mm. The three tracheal folds evi- dent marked with minute dots, as in citri. Tracheal pore opening almost on margin of case (fig. 6), the opening with a few teeth or fimbriae; body sutures distinct; along each side of median line of abdomen, a pair to each segment, and here and there on the thorax, are minute white dots in the derm, quite evident against the sur- rounding dark brown color of this region. The case is quite void of » no. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE & BAKER. 429 wax pores, though the derm shows the granular appearance usual in these forms. Vasiform orifice subcordate in outline (fig. 7); the anterior margin almost straight. The inner caudal margin is a thickened rim and is without the teeth so usual in species of this type. The operculum is similar in shape to orifice, almost completely filling it and covering the lingula. This latter (fig. 8) may be seen through the operculum and is elongate, slightly enlarged distally, setose, and bearing two long spines. On ventral surface the antennae (figs. 9 and 10) are quite evident, subcylindrical, and armed distally with a prominent stout spine (fig. 11); legs plainly visible, the feet (fig. 12) terminating in a disk-like structure usual for species of this type. Adults.—Unknown. Type.—Cat. No. 19055, U.S.N.M. DIALEURODES (GIGALEURODES) MAXIMA, new species. Plate 72, figs. 6-9. Specimens of this very large species were collected by Mr. George Compere, at Manila, Philippine Islands, in 1910. The host is Ficus species. Egg.—Length 0.21 mm. by about 0.1 mm., wide, subovate; stalk very short; color dark brown; covered with coarse polygonal mark- ings. Pupa case (fig. 6).—General color dirty yellowish white on leaf, without secretion; quite flat, festing both upper and lower leaf surfaces. Shape circular or nearly so; in size very large, measuring about 2.4 by 2.4mm. By transmitted light the color is yellowish, the evident marginal rim transparent. Dorsal area more or less marked with orange, which color is faintly present on the breathing folds. The margin is practically entire, though somewhat incised by the irregular ending of wax tubes. From the margin extend inward the usual sutures marking the position of the functionless wax tubes. A marginal area all around is faintly evident. Dorsum but little convex; the derm is figured with a network of polygonal markings; sutures not distinct; the tracheal folds are quite evident, tinged with yellow, and marked with minute dots; tracheal pores opening just within the margin of case, each with a subcircular chitinized ring, within which the margin is serrated (fig. 9), there beg no distinct finger-like processes or fimbriae; vasiform orifice (fig. 7) subcordate in outline, the cephalic margin straight, about as broad as long, and distant from the caudal margin about 0.592 mm. The rim of the orificeis thickened, and the inner lateral and caudal margin is minutely setose; the operculum has about the shape of the orifice, which it nearly fills, its caudal portion and protruding tip of lingula setose. On the ventral surface the legs are distinct and normal. 430 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 51. This species is noteworthy by reason of its large pupa case, m this respect resembling struthanthi Hempel, but easily separated from that species by its coloration, shape, and other details, as will be noted on comparison.

Pupa case (fig. 1).—Size 2.08 by 2 mm.; form almost circular; dorsum not greatly elevated; thorax marked off by a fine but very distinct suture; abdominal segments marked off only on the median area and there not distinctly so; color light yellowish brown, marked with dark brown. The subdorsal area is dark brown and this color extends more or less over the dorsal region. A band of dark brown extends across the thorax just cephalad of the suture separating it from the thorax, and is particularly dark just caudad of the opening of the thoracic tracheal folds. A band of dark brown extends around the margin, but this is sometimes broken by lighter areas. The pores of the tracheal folds are situated in the center of somewhat oval yellow areas. The surface of the case is corrugated, and the dark markings follow these corrugations, or sometimes take the form of reticulate areas. The pore of the tracheal folds (fig. 4) is situated almost on the margin and is armed with about nine rather blunt teeth. The fold itself is without sculpturing, but is irregularly wrinkled. The vasiform orifice (fig. 2) is very small, not much larger than the pores of the breathing folds. It is somewhat semicircular in outline, with the cephalic margin straight. The operculum is of the same shape, and almost fills the orifice, obscuring the lingula, which, when the operculum is removed, is seen to be elongate, setose, and armed with two spines (fig. 5). Submarginal area of case promi- nently fluted by sutures of wax tubes, the sutures extending well mesad (fig. 3). The above description is based on material received from Dr. H. von thering and collected at Sad Paulo, Brazil. Habitat.—Parnahyba and Sad Paulo, Brazil, on Struthanthis flexicaulis, orange, Mechilia flava, and on an unidentified forest tree. RHACHISPHORA, new subgenus. Within the genus Dialeurodes there are a few species which differ from all others in having a marginal row of spines, and this character is united with others which easily distinguish these forms from the | | ' No. 2156. SUBFAMILY ALEYRODINAE—QUAINTANCE € BAKER. 481 typical Dialeurodes. Such species fall into two groups. Those of the first group lack teeth on the vasiform orifice and a rhachis is more or less prominent. At first glance the most extreme of these shows little relation to the typical Dialeurodes. There is no doubt, how- ever, that fijvensis is so related, and this species shows the first indi- cation of the development of a rhachis, which has reached its culmina- tion in trilobitoides. In fijiensis there is a marginal row of 26 vasiform spines and other intermediate smaller ones. In #rilobitoides there is the same row of spines similarly placed, though they are not swollen to the same extent, and the presence of the rhachis suggested in fijensis is here very strongly marked. In rutherfordi the same vasiform spines are present as in fijiensis, though they are not so numerous, and the dorsal structure is midway between fijiensis and trilobitoides. These species are evidently closely related and may well form a distinct subgenus. Pupa case.—Elliptical or oval, light brown to blackish in color; marginal wax tubes represented by rounded or irregular short tooth- like projections; waxen secretion usually absent, though sometimes peculiar waxen dorsal figures present; dorsal disk with a more or less prominent rhachis and often with thickened ridges radiating from it, representing the body segments; no large pores present. Thoracic tracheal folds distinct; the pore area is composed of an outer ring, and within this is the smaller pore opening, which is usually armed with teeth; vasiform orifice broadly subcordate, with- out comb of teeth, but its caudal margin sometimes showing a pro- jection; submarginal area armed with a row of spines, and other spines also sometimes present on the margin.

Pupa case (fig. 1)—Size 1.5 by 0.95 mm.; outline oval, rather flat; abdominal segments distinct and indicating the development of a rhachis so prominent in other species of the subgenus; color straw yellow or pale brownish; margin (fig. 2) almost entire, the wax tubes being represented by irregular flattened tooth-like sections separated from one another by lines extending mesad; submarginal area armed with a series of spines composed of two kinds: The first large and vasiform, the second small and lanceolate. The vasiform spines form a row about the case as shown in the figure and are 26 in number. The smaller spines are placed in several more or less con- centric rows around the margin. The vasiform orifice (fig. 3) is roundly subcordate, with the margin rather heavily chitinized; the operculum somewhat similar in shape, though narrower caudad; lingula almost obscured by the operculum. ‘Thoracic tracheal pores very prominent, composed of a distinct, even, and heavily chitinized ring, which is present upon the dorsum, and within this ring is the rather elongate irregular opening of the pore proper. Tracheal folds quite distinct, extending mesad from the opening of the pore and not from the margin of the ring. The caudal pore is similar in con- struction to the thoracic marginal ones (fig. 4), but the dorsal ring is not so distinct. A rather well differentiated area extends from the vasiform orifice to the caudal margin, and on the median dorsal area there are a number of vasiform spines similar to, though smaller than, those upon the submarginal area. On the leaf the cases are light to dark brown in color and without marginal secretion of any kind. Dorsal waxen secretion very pecu- liar, forming, according to Kotinsky, a perpendicular column. It is fragmentary in the specimens at hand. Adult female.—According to Kotinsky this is as follows: Body (excepting head, which was bent under), 1.12 mm. long. Forewing, 1,406 microns long, 700 microns wide. Immaculate, mealy, yellowish white. Abdomen, legs, and antennae, except first two joints of the latter, testaceous; thorax, head, and first two antennal joints, straw color. Eyes slightly constricted, upper lobe consider- ably broader; reddish brown in color. Abdomen with about a dozen eggs distinctly seen ventrally; abdomen 750 microns long by about 325 microns wide. Only pupa cases are available to us for study. Habitat.—Rewa, Fiji, on pods and leaves of a leguminous plant. DIALEURODES (RACHISPHORA) RUTHERFORDI, new species. Plate 75, figs. 1-5; plate 74, fig. 1. A collection of this species on Loranthus was made by A. Ruther- ford, at Peradeniya, Ceylon, in June, 1913.

Pupa case (pls. 74 and 75, fig. 1).—Size 1.731 by 1.44mm., elliptic in outline; dorsum with a distinct but broad rhachis; transverse ridges of the abdomen representing the sutures between the abdominal seg- ments; color of case under the microscope yellowish brown, the ridges showing dark brown with lighter yellowish areas between them. Dor- sum covered with a large number of minute transparent tubercle-like structures, on which spine-like projections are situated, and also very many minute, more or less circular, dark brown markings. The margin is covered with numerous irregular tooth-like projections, many of which are armed with knobbed spines (pl. 75, fig. 5). Just within the margin there is a series on each side of seven or eight spatulate spines, like those seen in fijiensis, one spine being situated near where each dorsal ridge reaches the margin. The vasiform orifice (pl. 75, fig. 2) is subcordate in outline, with the anterior margin straight and the caudal portion of the rim extended. A very distinct furrow extends from the caudal extremity of the orifice to the margin of case, and here there is no distinct pore as is usual in the genus, but a comb of teeth (pl. 75, fig. 4). This character approaches very closely the condition met with in species of the genus Aleuroplatus. Thoracic tracheal folds distinct and ending in a faint, somewhat circular pore (pl. 75, fig.3). On the margin of the case adjacent to the pore there is a semi- circular sinus, which is armed with about a dozen minute teeth. Adults.—Unknown. Type.—Cat. No. 19057, U.S.N.M. DIALEURODES (RACHISPHORA) TRILOBITOIDES, new species. Plate 75, figs. 6-11; plate 74, fig. 2. Pupa case-—Pupa cases of this species were taken by Mr. A. Rutherford on Harpullia at Peradeniya, Ceylon, August, 1913. What seems to be the same species was taken by Mr. Rutherford on Eugenia operculata at the same place July 27, 1918, and also by Mr. R. S. Woglum, at Royal Botanic Gardens, Ceylon, on an un- known plant, October, 1910. The species shows a remarkable dorsal structure. The ridges of the abdominal segments have become interrupted, leaving a distinctly elevated and entire rhachis-shaped structure not unlike that met with in certain trilobites. The species show affinity with rutherfordi, and through this with fijiensis. Pupa case (pl. 75, fig. 6).—Size 1.04 by 1 mm.; shape oval, broadest across the second abdominal segment; color brown to almost black, darker along the median dorsal area; dorsum with numerous promi- nent ridges, as shown in the figure. These ridges are covered with fine hexagonal dark areas, and the submarginal area and the spaces 36399°—Proc.N.M.vol.51—16——28 434 PROCEEDINGS OF THE NATIONAL MUSEUM. vob. 51. between the ridges are covered with irregular rows of semicircular dark markings. Submarginal area armed with 26 spines mounted on tubercles, 13 on each side (pl. 75, fig. 7). Thoracic tracheal folds covered with small, dark, somewhat hexagonal markings similar to those present in other species of the subgenus; tracheal pore appar- ently composed of two parts—a dorsal, which is evenly pyriform in outline, and a ventral, which is contained within it, and is subcir- cular and toothed (pl. 75, fig. 9). Pore of the caudal tracheal fold appearing as a mere slit-like structure, having lost nearly all the characters shown by the thoracic pores (pl. 75, fig. 11). Vasiform orifice (pl. 75, fig. 10) subcordate in outline, with the cephalic margin straight. It is situated in the caudal angle of a somewhat heavily chitinized U-shaped structure; its rim well chitinized and armed at its caudal extremity with a prominent nipple-shaped projection. Oper- culum similar in shape to the orifice and almost entirely filling it, obscuring the lingula. On the leaf the pupa case shows no waxy secretion, appearing as shining, brownish-black disks, much ridged on the dorsum. Adults —Unknown. Type.—Cat. No. 19058, U.S.N.M. Described from pupa cases in balsam mounts, and dry upon the foliage. DIALEUROPORA, new subgenus. There is in the collection an aleyrodid from India and Ceylon which is quite similar to the typical Dialewrodes in regard to the structure of the tracheal folds and pores, and which has an orifice resembling that met with in some of the other subgenera of this genus, This form is remarkable, however, in possessing on the submarginal area a series of very large pores. On account of this and other noticeable characters it is placed in a separate subgenus. Pupa case elliptical in shape, yellowish or transparent whitish in color; marginal wax tubes represented by irregular, somewhat flattened, shallow, tooth-like corrugations; vertical waxen fringe absent; dorsal disk without sculpturing or rhachis; submarginal area with a series all around of a few very large simple pores; thoracic tracheal folds without sculpture or with a few minute dot-like markings; pore a ring-like opening near the margin; vasiform orifice broadly subcordate, the inner lateral and caudal margins without a comb of teeth; operculum similar in shape and nearly filling the orifice.

Pupa case (fig. 1).—Color on leaf dirty yellow; dorsum moderately convex; no dorsal or lateral secretions, except from submarginal area usually some 10 to 12 short waxen rods. Under the microscope the case is seen to be almost transparent, the segments moderately distinct. Size about 0.95 by 0.65 mm., sub- elliptic in outline, narrowing cephalad. Margin of case faintly crenulate (fig. 3), surrounded by a narrow zone paler than ad- jacent submarginal areas and separated from it by a more or less evident yellowish, thickened line. Within the margin there is a series of rather short spines, and along median line of case are several pairs of setae, as shown in figure 1. On each side of case, in sub- marginal area, are five large pores (figs. 1 and 2). Tracheal folds fairly evident and sparsely marked with dots (figs. 2 and 3). Vasiform orifice broadly subcordate, without teeth on inner margin. Opercu- lum similar in outline, nearly filling orifice (figs. 2 and 6). Adult.—Unknown. Type.—Cat. No. 19059, U.S.N.M. Described from numerous speci- mens on foliage and in balsam mounts. DIALEUROPLATA, new subgenus. This species was taken by C. H. T. Townsend in 1904, in the Philippine Islands. In general appearance it has many of the characters of typical species of the genus Aleuroplatus. It has some- what the same shape and color. It possesses numerous minute pores in the same regions, and the abdominal divisions are somewhat similar. It is much more completely a Dialeurodes, however, than it is an Aleuroplatus, and we erect for it the above subgenus. It seems further to confirm the apparently close relation of the two genera, Dialeurodes and Aleuroplatus. Pupa case.—Flliptical, broadest across the abdomen, slightly con- stricted at the thoracic tracheal pores; color brownish; marginal wax pores represented by shallow somewhat irregular tooth-like corrugations; submarginal area with an irregular series of minute, circular, pore-like structures; dorsum with a slight rhachis develops ment, particularly upon the abdomen, and with a number of minute pores. Thoracic tracheal folds not distinct; tracheal pores irregu- larly lobed or toothed within; vasiform orifice broadly subcordate, inner caudal and lateral margins without teeth; operculum similar in shape, nearly filling the orifice.

Specimens of this species are in the collection of the Bureau of Entomology from Lucerna, Tayabas, Philippine Islands, and were collected by C. H. T. Townsend on April 24, 1904. They were for- warded to the Bureau by T. D. A. Cockerell. The host is stated to be a “fern.” Egg (ig. 5).—Size 0.144 by 0.112 mm.; oval in shape with a short, curved stalk. Surface rugose and marked with peculiar circular areas giving it a very beautiful appearance. This egg sculpturing is different from that of any other in the family so far ‘observed. Pupa case (fig. 6).—Size 1.39 by 1.12 mm.; shape oval, flat, with a somewhat distinct median ridge; color yellowish brown with the median ridge dark brown. All about the submarginal area of the case and longitudinally along either side of the median ridge there are a large number of small transparent pores. The abdominal segments are well marked off, and the sutures separating them unite to form a distinct rhachis. A distinct suture from the middle of each segment of the rhachis extends across the dorsal disk. The margin is divided by a large number of fine lines extending a short distance mesad. The vasiform orifice is broadly subcordate in out- line and is almost completely filled by the operculum, which is setose on its distal extremity (fig. 7). Cephalad of the orifice there is a pair of minute setae and caudad of it the integument is thrown into a large number of fine transverse ridges. These merge into elongate polygonal markings which extend to the caudal pore along the tra- cheal fold (fig. 8.) The pores of the thoracic tracheal folds are small and irregularly lobed (fig. 9), and mesad of each is a large pyri- form structure, the interior of which is divided into a number of areas. The cephalic margin of case is armed with a pair of small sete. On the leaf there appears no waxy secretion, the insects showing as yellowish or brownish disks. Adults.—Unknown. Type. —Cat.

Color varymg from a dark to a very pale brownish, with the median area in some specimens more deeply shaded than the remainder of the case. Submarginal area armed with a row of prominent, curved spines situated on tubercles. These are usually 32 in number, but there are sometimes fewer. The margin itself (fig. 4) is rolled under the case somewhat after the manner of the species in the subgenus Lecanoideus. It is very minutely and irregularly serrate, but there are nothing like the prominent teeth which are present in some other forms.

Selena NOTES ON THE WHITFIELD COUNTY, GEORGIA, METEORIC IRONS, WITH NEW ANALYSES. By Grorce P. MERRILL, Head Curator, Department of Geology, United States National Museum. It will be recalled that in 1881 in the American Journal of Science (vol. 21), W. E. Hidden described an iron meteorite from Whitfield County, Georgia, and gave a cut illustrating the etched surface, but no chemical analyses. In 1883, C. U. Shephard, in the same journal, published a description of a still larger mass, weighing some 117 pounds, from near Dalton in the same county, and in this description expressed a doubt as to whether this iron might not be identical with that previously described by Hidden. In 1887, again, George F. Kunz in writing on the East Tennessee (Cleveland) iron suggested that this too might be identical with the large mass of the Whitfield County iron. This refers, presumably, to the Dalton of Shepard. It was for the purpose of deciding these questions that the present investigation was undertaken, opportunity for which was offered by the final acquisition by the United States National Museum of the Shepard collection, which contained the 117-pound mass. Referring to the two irons described by Hidden and Shepard, respectively — These differ quite radically in structure, as shown in plate 78, figure 1 being an etched surface of the iron described by Shepard, and figure 2 of the mass described by Hidden. The Hidden iron, it will be observed, is marked by broad plessite areas and a peculiar swelling of the kamacite bands, while between the two alloys are the regularly disposed, parallel-lying taenite bands. In the Shepard iron the kam- acite bands are not swollen, but show very straight borders, the taenite bands are thinner, so thin indeed, as to be scarcely recogniza- ble, and the plessite areas much less conspicuous. More important yet is the presence in this iron of small, irregularly scattered, granular, and dendritic particles of schreibersite, shown somewhat indistinctly in white in figure 1 of the plate. These were noted by Shepard and described as being often interrupted at short intervals, so that they resemble the markings of telegraph ribbons, and the continuous lines PROCEEDINGS U. S. NATIONAL MUSEUM, VOL. 5I—No. 2157. 447 448 PROCEEDINGS OF THE NATIONAL MUSEUM. vob. 51. sometimes swelling into triangular or polygonal enlargements form- ing a string of nearly disconnected beads. Shepard, however, did not discriminate between the taenite and schreibersite, and the two are often so closely associated and intergrown as to make this a matter of difficulty. The most characteristic distinction is that the taenite lies in very thin films parallel to the kamacite, while the schreibersite is in knots, granules, and dendritic forms, sometimes by itself but often attached to or continuous with the taenite films. That these forms are of the phosphide has been determined by separation and microchemical tests. There is, further, a marked difference in the manner in which the two irons etch, the Hidden iron etching quickly and yielding a bright, lustrous surface, while that described by Shep- ard, under precisely the same conditions, is acted upon much more slowly and gives a dull surface, on which the figures show less dis- tinctly. An analysis of the Shepard iron as given in the paper referred to shows: Per cent.
