The Pan-Pacific Entomologist Vol. XVI, No. 1 January, 1940 HENRY CLINTON FALL* On November 14, 1939, the Pacific Coast Entomological Society lost by death one of its oldest and most distinguished members, Dr. Henry Clinton Fall. A charter member of the Society in 1901, chairman of its first meeting, vice-president from 1902 to 1910, and corresponding member from his retirement in 1917 until his death, Dr. Fall has left an indelible imprint on the organization and in the hearts of its members. Dr. Fall was born in Farmington, N. H., on December 25, 1862, the son of Orin Tenny and Mary Anne Hayes Fall. He attended preparatory schools in Dover, N. H., and in 1884 gradu- ated with the degree of Bachelor of Science from Dartmouth College. In 1929 he was honored by the further degree of Doctor of Science bestowed by his Alma Mater. His interest in insects began at a very early age and was encouraged and stimulated by his mother. It is said that at the age of sixteen years he had progressed to the state where he was considering the advis- ability of starting a pinned collection of insects. With his mind still undecided he captured a large longicorn beetle, Prionus pocularis Dalm., which influenced him in favor of the enterprise. Dr. Fall’s professional life was devoted to education, par- ticularly in the field of mathematics. His career began in Illi- nois at the Chicago Manual Training School and was continued in California where he was head of the Science Department of Pasadena High School from 1896 to 1911. He came to this state in 1889 because of ill health and it was here that he gained recognition as a great Coleopterist. His first scientific article, “California Notes,” appeared in the Entomological News for 1893 and was inspired by a visit from Dr. George Horn. It made known some observations on the habits and distribution of sev- eral species of little known southern California beetles. This article was followed in the succeeding years by one hundred and twenty-five or more papers, many of which were of a revisional ♦Read before the Pacific Coast Entomological Society at its meeting of December 2, 1939. 2 THE PAN-PACIFIC ENTOMOLOGIST [y 0 L. XVI NO. 1 or monographic nature and all of which were written on his own time, time which is wasted by many men. The best known of his revisions were those of Apion (1898), Acmceodera (1899), Lathrididce (1899), Ptinidce (1905), Diplotaxis (1909), Pachy- brachys (1915), Gyrinus (1922), Agabus (1922), and Hydro- porus and Agaporus (1923). Among his faunal works are sev- eral of special interest to western entomologists and to students of geographical distribution. These include his lists of the Coleoptera of the southern California islands (1897) and the Coleoptera of southern California (read before the Pacific Coast Entomological Society in 1901 and published by the California Academy of Sciences in the same year) , as well as his reports on the Coleoptera of New Mexico (with Cockerell, 1907) and Alaska (1926). The latter report was published by the Society in the Pan-Pacific Entomologist. The early work of Dr. Fall in southern California served as a stimulus for many western coleopterists, particularly Dr. E. C. Van Dyke, Dr. F. E. Blaisdell, Dr. A. Fenyes, Mr. Ralph Hopping, and Mr. J. 0. Martin. These men were assisted by his careful determinations and reciprocated by providing much of the ma- terial upon which his early monographs were based. However, Dr. Fall, himself, was a good collector and field systematist. He collected in nearly all parts of the country at some time or other, but more especially in New England, Florida, California, and Alaska. He assembled what was, at the time of his death, the finest private collection of Coleoptera on this continent. It is said to have contained more than two hundred thousand mounted specimens representing some twenty thousand species and in- cluding about fourteen hundred types. These last were kept in separate boxes arranged in chronological order. All of his speci- mens were beautifully and carefully mounted, neatly labelled, and perfectly arranged, reflecting his methodical and systematic mind. The majority of the species had been determined by care- ful comparison with types, a fact which greatly enhances their value. Even while he was residing in California, Dr. Fall spent the majority of his summers in the East studying the type speci- mens of the species described by LeConte, Horn, and other early workers. After his retirement from active teaching in 1917, most of his time was spent in the study and arrangement of his January, 1940] LINSLEY— FALL OBITUARY 3 collection and in assisting others with determinations and type comparisons. His collection was left to the Museum of Com- parative Zoology, where it will be housed near that of his great predecessor, Dr. LeConte. One of the things which Dr. Fall had long planned to do, and which now, unfortunately must remain undone, was the presentation to the California Academy of Sci- ences of a duplicate set of the numerous species which he de- scribed from this state. This action would have been of inesti- mable service to the western systematists and it is to be regretted that the plan was never consummated. In addition to his more serious studies, Dr. Fall at one time or another, made collections of butterflies and of postage stamps. He was also fond of tennis and enthusiastic over parlor games, which he played with a good deal of skill. One of the older entomologists once recounted to the writer an incident which occurred at the Fall home in Pasadena. My friend, who con- sidered himself quite skillful at cribbage, had been playing all evening without winning a game. Finally, in desperation, he exclaimed that Dr. Fall was inordinately lucky and that anyone could win who drew such excellent cards. With a smile, Dr. Fall suggested that they exchange the hands which they had just played and with which he had so easily won. They did so and once more he completely overwhelmed his opponent. Although future generations of entomologists will place the name of Henry C. Fall beside that of John L. LeConte and George Horn as one of the greatest North American Coleopterists, he will be remembered by the members of the Society as a fine, scholarly gentleman, beloved by the older generation as a friend, colleague, and good companion on camping and collecting trips, and by the younger generation for the constant encouragement and patient help he so freely gave to all who asked. Dr. Fall died at the age of 76 at the home of his sister, Mrs. Carl A. Richmond, at Tyngsboro, Mass., where he had resided since his retirement in 1917. Honorary pallbearers were Nathan Banks, William J. Starr, Frank A. Richmond, and Dr. W. M. Lougee. Active bearers were Dr. P. J. Darlington, R. W. Sher- burne, C. H. Quesen and R. C. Turner. He was interred in Pine Grove Cemetery, Farmington, N. H. — E. Gorton Linsley. 4 THE PAN-PACIFIC ENTOMOLOGIST [yQL. XVI NO. 1 A NEW GEOPHILUS FROM SAN NICHOLAS ISLAND, CALIFORNIA BY RALPH V. CHAMBERLIN University of Utah From Professor T. D. A. Cockerell I recently received for identification two chilopods collected on islands off the coast of California. A specimen taken on San Miguel Island by Anna Duszen is a female of Ethopolys xanti (Wood), a species wide- spread on the California mainland. The second specimen, taken on San Nicholas Island by Harry Allen, is a female of an inter- esting and apparently previously unknown species of Geophilus, which is described below. Geophilus nicolanus Chamberlin, new species Color of type specimen dark brown, the anterior segments and head, and the posterior segments lighter brown or fulvous. Cephalic plate very slightly wider than long, widest at middle ; sides convex, the posterior margin straight or nearly so and the anterior margin convex. Frontal suture distinct. Median piece of labrum strongly sclerotized, dark in color, bearing five or six short conical teeth; the lateral pieces pectinate as usual. First maxillas with telopodite of two articles; two external lappets well developed. Antennse three times as long as the cephalic plate, with the ultimate article much shorter than the two preceding taken together. Prebasal plate not exposed, the cephalic plate overlapping the basal plate, the exposed portion of which is about three times as wide as long. Prehensors when closed equalling, or but slightly surpassing, the anterior margin of the head. Anterior margin of coxosternum forming a very obtuse reentrant angle, smooth, chitinous lines incomplete at anterior end. None of the articles dentate within. Claw stout, smooth. Dorsal plates bifurcate. Last plate somewhat shield-shaped, with posterior angle truncate. Ventral plates in anterior region decidedly wider than long. A few sternites pre- ceeding the ultimate nearly as long as wide. Ventral pores across posterior border. First spiracle large, subelliptic, the second of similar form and size, the third much smaller, it and the following circular. Last ventral plate very wide, wider than long in about the ratio 15:8; sides convex, converging caudad, the caudal margin mesally incurved. Coxal pores numerous, arranged along and beneath the border of the ventral plate, twenty to twenty-four exposed on each side. Anal legs in the female slender, with the claw normal. Anal pores not visible. Sixty-three pairs of legs in female holotype. Length, 62 mm. Locality: San Nicholas Island, California. One female col- lected by Harry Allen and transmitted by Professor T. D. A. Cockerell. January, 1940] melander— genus microphorus 5 THE DIPTEROUS GENUS MICROPHORUS. I. PHYLOGENY (Diptera Empididas) BY A. L. MELANDER College of the City of New York This paper is dedicated to Elizabeth Thompson, whose in- terest in science made possible the collection of many of the specimens enumerated herein. In 1922 the writer received a grant from the Elizabeth Thompson Science Fund for the pur- pose of studying the insects of Mount Rainier, in the State of Washington. With this assistance an extended trip was made with pack horses beyond the usual tourist roads. The alpine regions of Mount Rainier have been visited by the writer on six additional collecting trips, and on nearly every occasion speci- mens of Microphorus have been encountered. They are small black Empid flies, sometimes to be secured in great numbers by the sweeping net in the meadow slopes. Representatives mounted from many collecting localities along the Pacific slope when later examined proved to belong to several species, some of which were undescribed. The present study is an attempt to visualize the evolutionary development of this genus through an evaluation of the degrees of relationship of the several species to each other. The genus Microphorus was erected in 1827 by Macquart, who then called it Microphor. In 1834 he corrected the name to Microphorus , giving its etymology as the little plunderer. Because the source of the term is thus the Greek phdr , spelled with the long omega, and not the commonly encountered phdr, carry, which is spelled with the short omicron, the accent be- longs on the penult, and the genus name is to be pronounced Mi-cro-pho-rus. This genus has been confused in the minds of many. Of the American species which at one time or another have been re- ferred to Microphorus the following assignments can be made. Microphorus drapetoides Walker is described in such general terms as to be unrecognizable; it may be an Anthe pisco pus. M. scapuliferus Bigot, from Chile, has been placed by Collin in Atricho pleura, and Bigot’s M. semifulvus in Platy palpus. In 1902 I used Holoclera in the sense of Microphorus. Coquillett, in his analysis of Empid genera in 1903, located in Microphorus 6 THE PAN-PACIFIC ENTOMOLOGIST [yOL. XVI NO. 1 the diverse species Anthe pisco pus flavipilosus Coquillett, An- the pisco pus stentor Melander, Trichina atripes Melander, Euthy- neura crocata Coquillett, Euthyneura aperta Melander and Sciodromia palliata Coquillett; and transferred two typical species of Micro phorus, M. atratus Coquillett and M. sycophantor Melander, to Anthalia. It would seem from the confusion regarding the identity of Microphorus that the genus would be hard to recognize. That is not the case, for the species can be picked out at a glance. All our species are small, black-bodied and black-haired, with gib- bous thorax, the males with large holoptic head and with the genitalia massive and curiously twisted to the right. Among the Empididas they are set off by the small basal and anal cells of the wing. Because of their striking sex dimorphism it has been more difficult to associate females with their appropriate males than to place either in the genus. The allied genus Micro phorella contains even smaller species, both sexes dichoptic, with pubes- cent eyes and with the anal angle of the wing greatly reduced. Classification of the species within a genus may be presented as a visualization of the phylogeny of the group. While obviously nothing can be proved of the happenings of the past with regard to the actual origin of species, it is possible, by a study of cor- related characters, to picture the groupings of species and their relations to each other. Some characters, possessed in common by a series of species, may be regarded as ancestrally generalized; other characters, possessed by relatively few, may be considered to be recently specialized. Applying this working principle to Microphorus we see that cirri pes (fig. 18 ) alone of all the species has the front femora of the male fringed with curled hairs. This unique fringe may therefore be regarded as a highly specialized char- acter. Since cirri pes further is the only species that possesses a much warped wing and has developed the bristle armature of the fifth ventral segment to the extreme, it is probable that cirripes is a very recently evolved species, measured by the wide terms of biological time. Other recent species, as indicated by the unique possession of specialized characters, are hilineatus which has two polished thoracic vittse, tacomce which has the seventh tergite polished, and discalis which has the largest discal cell in the genus.

The figures are drawn freehand and therefore are to be re- garded as diagrammatic. 8 THE PAN-PACIFIC ENTOMOLOGIST [yOL. XVI NO. 1 A comparison of structures possessed in common by cirripes and any of the other species of Microphorus shows that ravidus and strigilifer are the closest relatives of cirripes. These three species form a group differentiated from the congeners by the structure of the middle legs of the males, which possess three strong femoral bristles and a distorted tibia, a correlation not to be found elsewhere in the genus. Other index characters which show group relationship are the numerous minute acrostichal hairs of obscurus and bilineatus, and the bilobed and spinose fourth ventral segment of the males of isommatus and evisceratus. That these groupings are natural is further indicated by the correlation of other characters with the index characters mentioned. The numerous acrosticals de- veloped only in the species obscurus and bilineatus are asso- ciated with a conical third antennal joint (figs. 1, 2), shortened style, piercing proboscis, clavate hind tibiae and swollen hind metatarsi. The same combination of characters occurs also in the European species anomalus. All of our other species of Mi- crophorus, all of which are limited to the western states, mani- fest a peculiar formation of the antennae, the third joint becom- ing more or less constricted beyond its base and the style length- ening to an arista (figs. 3-11). This tendency to constriction reaches its culmination in discalis, where the distal part of the third joint is a strap-like elongation (fig. 11). Since constricted antennae are distinctive of Microphorus, while the related genera have the conical form, it follows that the obscurus-bilineatus- anomalus group represents an ancestral condition, at least as concerns antennal structure. Secondary sexual characters are highly developed in the male of Microphorus. The genitalia are unusually large, dis- torted and always flexed to the right; the terminal abdominal segments often develop spines, or groups of bristles, or expanded plates; the legs may be distorted or swollen, and usually show some distinctive arrangement of stout blunt bristles not pos- sessed by the females. Such departures from the conservative female structure may be regarded as specializations, and the greater the departure the higher the degree of specialization. When pictured as a phyletic tree the generalized species should form the lower and shorter branches and the specialized species should show the greater evolutionary growth. January, 1940] melander— genus microphorus 9 It will be noted that in this genus there are certain tendencies which outcrop in various lines of ascent. The swelling of the hind legs of the archaic obscurus-bilineatus group is paralleled in robustus and armipes. There is a tendency in several species to transform the ventral hairs immediately in front of the pygid- ium into short spinous bristles. The nearly conical third an- tennal joint of the highly specialized ravidus is suggestive of the primitive conical antennae of obscurus. Bleaching of the halteres has been accomplished independently in various species. Also, several species show the tendency to elongation of the discal cell, while others develop a curvature of the third vein. Taxonomy always faces the problem of deciding what char- acters are homoplastic and what characters show genetic rela- tionship. The parallelisms in the development of the structures mentioned in the preceding paragraph do not indicate a common origin. Personal interpretations vary with the individual ento- mologist to an extent that what might appear to be a natural iden- tification key to one taxonomist might be considered an artificial key by another. The tabulation of the females of Microphorus as presented in the second paper of this series is not a natural classification. The species did not arise phyletically as listed in the table, nor are natural groupings indicated by the relative length of the sections of the fifth vein or the number of dorso- central bristles and hairs. But the tabulation of the males prob- ably has more genetic basis, made possible by a greater diversity of index characters displayed by this sex. In some species of this genus the males are more abundant than the females. With their ferocious and bloodthirsty natures, the males may display a rivalry, which may have been responsible for the spectacular array of secondary sex characters developed by this sex, and such characters have great value in the diagnosis of species. As to atavic index characters, first suggested by Osten Sacken in 1894, speciation in this small genus is apparently too recent to afford much use of such ancestral traits. Atavic indices are those inconsequential structures which have escaped the action of natural selection, and hence persist unmodified through the ages. The short style of the obscurus-bilineatus -anomalus group is an example of atavic index; but the stiffened bristle of the middle trochanters of certain males, while a group index indicating relationship, is too specialized a character to be considered an atavic index. 10 THE PAN-PACIFIC ENTOMOLOGIST [yoL.

January, 1940] BOYER— HOPLIA SYNONYMY 11 Microphorus affords good illustrations of the varying speed of evolution in developing different structures. M. obscurus , for example, possesses an archaic antennal structure coupled with modernized swollen hind legs. M. evisceratus has produced a most remarkable deformity of the abdomen while retaining the small ommatidia of its remote ancestors. The excavation of the hind metatarsus of strigilifer is undoubtedly a recent acquisi- tion, geologically speaking, developed amidst the conservative pattern of the hairs of the legs. M. strigilifer shows a rudimen- tary deformity of the middle tibiae of the male, which later de- veloped into a pronounced callus in the species ravidus and cirripes. Comparing the three species, strigilifer , ravidus and cirri pes, strigilifer would be rated as the most recent if the struc- ture of the hind legs alone were used as the criterion; while its middle legs would indicate that it is older than either of the two other species. Judged by the front legs, cirripes is clearly the youngest species. An expansion of the wings near the middle of the hind margin might suggest a close relationship between strigilifer and cirripes , but this expansion is another instance of homoplasy, since it is only a superficial similarity, centering at the end of the intercalary vein in cirripes and at the end of the fifth vein in strigilifer.

Wings large; venation oligotomoid; pigment bands broad, dark; hyaline stripes narrow, clearly, sharply defined. Hind basitarsi with but one bladder. Terminalia with tenth tergite divided sub-medially, each of the thus-formed hemitergites bearing distinct caudal process; process of hypandrium not prominent; left cercus two- segmented, the basal segment with an echinulate nodule on inner side; left cercus-basipodite not prominent, ventral. Females: No mature examples available for study. Genotype: Oligotoma hospes Myers, ibid., fig. 1. Distribution: West Indies. The two-segmented echinulate left cercus in combination with the oligotomoid wing venation will distinguish Mesembia from all other known genera. Besides its type, hospes of Cuba, this genus also contains a new species from Haiti which will be de- scribed later.

January, 1940] BEER— OREGON RUPRESTIDJE 13 NOTES ON SOME BUPRESTID7E OF SOUTHWESTERN OREGON (Coleoptera) BY FRANK M. BEER Grants Pass, Oregon During the winter of 1938-39 and the following spring and summer, a number of unusual Buprestidae were taken in south- western Oregon which may be of interest to collectors. Along with this, some observations were made on the habits of others, which, I believe, are worthy of mention. The flora of the Rogue River Valley 1 is generally considered to be predominantly Californian. The mountainous country on the southern border of the valley is, topographically, a westward extension of the Sierra Nevada and Cascade ranges and their connection with the Coastal range. It is here that many of the semi-desert plants of the Sierra and Great Plain region gain en- trance and extend into this area. Thus, with their host plants present, it is not surprising that a number of typical Californian Buprestids should be found here. POLYCESTA CALIFORNICA LeC. Though this species has been reported as common from south- ern Oregon and from a number of hosts, it is interesting to note that willow ( Salix sp .) , hitherto unlisted, is also one of its host plants. AcmjEODera plagiaticauda Horn Although this species has not been reported from southern Oregon, it is not surprising to find that it occurs here. Two specimens were dug from manzanita ( Arctostaphylos viscida) about two miles east of Murphy, Josephine County, Oregon. Later, two specimens were collected from the same host near Trail, Jackson County, Oregon. One was dug from a wood scar, the other was taken while feeding on a cluster of young leaves. The larvas stay near dead wood and are generally found very close to the ground. 1 Piper and Beattie, The Flora of the northwest Coast, p. iii. 14 THE PAN-PACIFIC ENTOMOLOGIST [yQL. XVI NO. 1 Acm^odera connexa LeC. During the middle of February while collecting in a burn that had occurred in the fall of 1931, seven adult specimens and a number of larvae of this species were dug from the heart-wood of oak ( Quercus garryana) . The trees varied in size from about three to six inches in diameter and still had solid wood. The collection was made on Humbug Creek, two and one-half miles from Applegate, Jackson County, Oregon. Very little variation in markings was noted. At various times during the spring, specimens almost identical were collected near Grants Pass from one of our fire weeds ( Epilobium sp.) and from a composite ( Monolopia major ) from Copper, on the upper Applegate River. Acjyleodera sinuata var. sexnotata Van Dyke Five specimens of this unusual variety were taken in the valley; all were typical and showed little or no variation in markings. Two specimens were dug from chaparral ( Ceanothus cuneatus) , one being collected about two miles east of Murphy, Josephine County, Oregon, on an exposed hillside of the Apple- gate Valley, the other under identical conditions about one mile west of the city of Rogue River, Jackson County, Oregon. Later, three specimens were swept from the above reported host grow- ing near Grants Pass. Acmjeodera angelica Fall Fourteen specimens of this little Buprestid were collected at various places throughout the valley. Five were dug from the heart wood of chaparral ( Ceanothus cuneatus ), and others were collected in flight near, or swept from, the dead branches of the host plant. Melanophila intrusa Horn This is by no means a common species in our locality. It is found on pines which are dying, and usually only on trees that yet have a little life as shown by the fact that spring buds had developed a short distance. A number of specimens were ob- served on young fire-scorched pines, but none was seen on nearby trees which had been completely killed. January, 1940] BEER— OREGON BUPRESTIDAD 15 Melanophila occidentalis Obenberger It seems surprising to find this species so far north, as Sloop 2 reports it only from California, recording specimens taken from Orange County. However, as reported by Van Dyke 3 and Linsley 4 and as shown by Sloop 5 , these forms have a special sensory pit which makes them sensitive to acrid odors and fumes, and since they have been known to travel long distances to fires, etc., it is not really surprising that we should find the species here. As Sloop stated, the adults and larvas were collected from oak. Both Oregon white oak ( Quercus garryana) and California black oak (Q. calif ornica) are hosts, as is also Madrona ( Ar- butus menziesii ) . I suspect that careful examination of our boxes of Melanophila would prove this species to be confused with acuminata , and that they may be rather widely distributed in our western region. The species can readily be determined by dissection of the genitalia. Melanophila consputa LeC. The larvae of this species are very common in the charred, fire-killed limbs of second-growth yellow pine ( Pinus ponde- rosa) and lodgepole pine ( P . contorta ) . They are very common where the trees are scattering, as in the fringe type stand. Pupat- ing insects have been found near the heart-wood of limbs in all cases. More recent observations have shown this species to be very common just after a fire, and they were observed to oviposit on both the trunk and limbs. However, no larvae or pupating specimens have been found other than in the limbs. Chrysobothris cyanella Horn This is another little insect that is very common in our region, extending its range from the valleys to the summits of the Cascades and Siskiyous. Chamberlin 0 reports yellow pine ( Pinus ponder osa) as the probable host, but the larvae are found to inhabit the woody roots of the wild buckwheat ( Eriogonum nudum) on which they are so often collected.

Chrysobothris dolata Horn Two specimens, both males, were reared from a limb of Douglas fir ( Pseudotsuga taxi folia) which was picked up at Prospect, Jackson County, Oregon. This is a new host plant for this uncommon insect. Chrysobothris calcarata Chamberlin Three males and a single female were collected on chaparral ( Ceanothus cuneatus ) near Wilderville, on the banks of the Applegate River. No females were known to Chamberlin 7 at the time he described the species. The female antennae are cop- pery-bronze, serrate from the fourth segment and narrowing toward the tip; the first segment is as long as the next two com- bined as in the male. The upper surface is much less pubescent. The last ventral segment is rather completely rounded, similar to that of C. harrisi Hentz. The “wide smooth line running from the base to almost one-half way to the front” of the pronotum is not entirely constant in all cases, but with several specimens it can be determined. An odd act exhibited by this species is a unique way of flicking the abdomen as the insect crawls around on small twigs in the sun. It is rather an unusual circumstance that this species should occur this far north since the type specimen was taken at Pres- cott, Arizona. 7 Chamberlin, W.

A Record of Physocephala affinis Williston as a Parasite of Adult Bembix comata Parker The sand wasp, Bembix comata Parker, which nests in the sand flats at Emeryville, California, is frequently parasitized by the conopid fly, Physocephala affinis Williston, which can be collected nearby on sweet clover blossoms. The habits of the fly at this locality are similar to those recorded in a recent paper 1 for the same species as a parasite of Bembix occidentalis beu- tenmuelleri Fox. — By G. E. Bohart and J. W.

The holotype, a male, and the allotype, both of which are deposited in the author’s collection, were collected at the Frances Simes Hastings Natural History Reservation, near Jamesburg, Monterey County, California, from Thomomys bottce subsp. on May 26, 1938, by C. P. North. Only these two specimens are known. Family Hystrichopsyllidje Atyphloceras longipalpus Stewart, new species This species appears to be more closely related to A. felix Jordan, 1933, than to any other known representative of the genus. Head. Labial palpi with more segments than in any previously described species: nine in the female and eight in one palpus and nine in the other in the male.

Holdenreid. Atyphloceras FELIX Jordan Atyphoceras [sic!] felix Jordan, Novitates Zoologicse, 39:69, 1 fig., 1933. Only the male of this species was described by Jordan. In his description it is stated that the labial palpus is seven- segmented. In our specimens the labial palpi of both the males and the females may have either seven or eight segments. We have in our collection twenty-two males and twenty-eight females collected at the Frances Simes Hastings Natural History Reser- vation, near Jamesburg, Monterey County, California, on Pero- myscus calif ornicus subsp., P. truei subsp. and Microtus cali- fornicus subsp. from June 18, 1938, to January 11, 1939. The female of this species is accordingly described below. Head of spermatheca subglobular in shape and tail relatively stout (Fig. 11) ; thus closely resembling the female of A. bishopi Jordan, 1933. Dilated portion of bursa copulatrix shaped much like the pod of a bean, as in bishopi, but distorted at times in such a way as to give a somewhat triangular shape. Posterior margin of seventh sternite, in most of our specimens, with two well de- fined lobes; a lower one with a more or less straight margin rounded at upper corner and separated by a deep conspicuous sinus from the small rather acutely pointed upper lobe, this latter extending posteriorly nearly as far as lower lobe. Margin of this sternite variable, however. Upper lobe very sharply pointed in some specimens, rounded and much smaller in others and, in one specimen, lacking and thereby greatly resembling this seg- ment in A. longipalpus Stewart. Eighth tergite with a vertical row of about six spine-like bristles, the lower four of which are very short. Stylet about three and one-half times as long as broad at base and only very slightly narrowed apically.

DREWS University of California, Berkeley Gymnaleurodes Sampson and Drews, new genus Pupal case elliptical to subovate in outline; margin of the case crenulate, the submarginal area not separated from the rest of the body. Several rows of tooth-like structures found behind the mar- gin, the outer twice as long as the inner. Dorsum without papillaa or pores. Vasiform orifice cordate; the operculum transversely elliptical, filling about one-half of the orifice. Lingula spatulate, with distal extremity exposed beyond operculum, lobed and without spines. No caudal furrow present. Marginal fringe consisting of numerous glass-like rods. Abdominal spines not over four. Genotype: Gymnaleurodes bellissima, new species. This genus differs from Aleyrodes, in that the margin of the pupal case is not crenulated in the same manner, the operculum is not of the same shape; also the shape and spination of the lingula differ. In addition this genus is somewhat like Trialeu~ rodes, except that there is no elevation of the case. There are no pores or papillas, no caudal furrow, and no notch at the poste- rior edge. There is some resemblance to Pealius, but the oper- culum is not of the same size and shape; there is no caudal furrow, the vasiform orifice and lingula are not of the same form. Gymnaleurodes bellissima Sampson and Drews, new species Pupal case. Case laterally constricted cephalically, with a slight inward indentation at caudal end. Color of case a dirty yellow, with some pale reddish-brown markings on dorsum; color much more clear and striking in live specimens. Specimens para- sitized by fungi slightly darker in appearance. No indication of wax on dorsum. Dorsum imbricated, particularly toward the edge, irregularly toward the top, more regularly toward the edge. Cephalothorax laterally constricted, rounded in front. Four irreg- ular rows of small pores or setaa on abdomen, with a group of three pores concentrated cephalically and laterally on each side of vasiform orifice. Vasiform orifice cordate, with anterior margin straight; about twice its length from posterior margin. The hair on each side of the orifice about one and one-half the diameter of its base away from the orifice; length of hairs approximately one- quarter the width of orifice. Lingula usually with three lobes on 30 THE PAN-PACIFIC ENTOMOLOGIST [yoL. XVI NO. 1 each side; apparent projection of tip of lingula due to transverse fold caudad of third lobe of lingula. Two rows of teeth found be- hind the margin. Ten dentations to 0.1 mm. of margin. First row of teeth projecting over syncline of crenulations; second row of teeth over syncline of first row. Marginal fringe of shiny crystal- ine rods about one-half the width of pupal case. Rods of the mar- ginal fringe thicker and appearing white at 3 points, the first being at central posterior area and the other two located at middle of sides of thorax.

Anystis agilis Banks, a Predacious Mite on Eggs of the Artichoke Plume Moth The large reddish mite, Anystis agilis Banks, is a common species on the globe artichoke ( Cynara scolymus L.) in the Half Moon Bay area, where it preys on newly laid eggs of the arti- choke plume moth ( Platyptilia carduidactyla (Riley), many collembolans, and the artichoke aphis ( Capitophorus braggii (Gillette). It is a well known and common predator, but its predacious habits on eggs of the plume moth were considered of unusual interest. I am indebted to Dr. H. E. Ewing for the determination of the mite. — W. H. Lange, Jr. January, 1940] DRAKE AND HARRIS— VELIA 31 A NEW VELIA FROM PERU (Hemiptera, Veliidge) BY C. J. DRAKE AND H. M. HARRIS Iowa State College, Ames, Iowa Velia willei Drake and Harris, new species Large, rather elongate; brown, the hind margin of the pro- notum yellowish, and the tips of all femora and basal portion of posterior tibiae blackish. Head dark brown, with the usual im- pressed lines. Eyes blackish. Antennae dark brown, moderately long; segment I rather stout, somewhat curved and enlarged dis- tally, II faintly enlarged distally, stouter than the apical two; proportions, I: II: III: IV = 50:40:37:40. Pronotwm slightly more than one-fourth longer than broad, the hind margin rather broadly rounded; coarsely pitted, with distinct median longtitudinal ridge, the humeri slightly raised and prominent. Legs moderately stout, the tarsi dark. Connexivum distinctly produced behind. Rostrum reaching to middle of mesosternum, the apex black. Venter brown with blackish markings, the last two segments longer than the preceding, the apical one broadly, roundly excavated. First genital segment above densely clothed with long blackish hairs. Second segment strongly sharply tumid behind, with a conspicuous tuft of black hairs on each side. Clasper long, curved, and tapered distally, the apex slightly twisted. Length, 7.2 mm; width, 1.6 mm. Holotype, apterous male, Santa Eulalia river, Peru, March 29, 1935, J. E. Wille collector; authors’ collection. Velia willei belongs to the Velia invemglas Kirkaldy group of species. It is unique in that the genital segments are very hairy and the suranal plate lacks the hooks characteristic of most of the other forms. However, the two tufts of hairs on the suranal plate are curved and tapered and strongly resemble suranal hooks. A NEW PIESMID FROM INDIA (Hemiptera) BY CARL J. DRAKE Iowa State College, Ames, Iowa The writer is indebted to the authorities of the Vienna Museum for the privilege of studying a small collection of Tingitoidea from India. A new species of Piesmidae is described below. 32 THE PAN-PACIFIC ENTOMOLOGIST [yoL. XVI NO. 1 Piesma distans Drake, new species Moderately large, whitish cinereous. Head long, juga and tylus subequal in length. Eyes moderately large, dark. Ocelli small, reddish. Rostrum dark at apex, extending to intermediate coxae. Middle and hind coxae not widely separated, also placed closely together as pair. Rostral channel deep on prosternum and anterior portion of mesosternum, from there to apex strongly raised so as to form a ridge-like plate which is narrowed poste- riorly and shallowly grooved. Legs short, stout, grayish brown. Antennse moderately long, grayish brown; segment I short, very stout; II shorter and much more slender than I; III very slender, one-fifth longer than IV ; IV considerably swollen, brownish. Pro- notum deeply pitted, becoming smoky brown behind, the carina on each side of median line in front prominent; lateral margins be- coming widely explanate anteriorly, three cells deep in front, the outer margin broadly curved; hind margin broadly curved. Elytra divided into areas as other long winged members of genus, the costal area uniseriate; membrane distinct. Scutellum small. Length, 3.00 mm.; width, 1.80 mm. Holotype (male) and allotype (female) Bombay, India, October 20, 1901, collected by Dr. Urei, Vienna Museum. Two paratypes, taken with type, Drake collection. The pronotum is not very thick. The explanate lateral mar- gins and carinas are typical of members of the genus Piesma LeP. and Serv. The characters of the head, except the length of juga, are also typical of the genus Piesma. This is the first record of this genus in India. NEW LEPTURINI (Coleoptera, Cerambycidas) BY RALPH HOPPING Vernon, British Columbia The two new species herein described have been in my col- lection for some time and were given to me by Dr. R. D. Bird of Oklahoma and Mr. Kenneth M. Fender of McMinnville, Oregon. Toxotus spinosus Hopping, new species Male. Length 14 mm. Entirely black except the abdominal segments. Head with antennse having the third segment longer than the fourth; eyes moderately prominent and punctation fine January, 1940] HOPPING— NEW LEPTURINI 33 and irregular; line of the cheeks behind the eyes straight. Pro- notum much longer than wide; rather deeply, broadly impressed transversely both apically and basally; median longitudinal im- pression shallow and not smooth; surface rather finely and irregu- larly punctured, with lateral tubercles obtuse. Elytra subcostate, 3 mm. wide at the base, with apices obliquely truncate, length 9 mm. Vestiture golden, especially on margins, the abdominal seg- ments rufo-testaceous, with very long tibial spurs. Female. Length 17 mm. Differs from the male only in its larger size and stouter form. Holotype, male, bearing the label “McMinnville. Ore., 5/9/36.” Allotype, female, bearing the label “Oak Ridge, V-31-24, G. R. Hopping.” Paratypes, three males from McMinn- ville, Oregon, two of which are in the collection of Mr. Kenneth M. Fender. Four other specimens are before me from Dayton, Oregon, which is not far from McMinnville, and Oak Ridge is in the same region. This species is nearest vestitus Hald., but differs in having a much broader and deeper transverse sulcus at the apex of the pronotum, the vestiture golden instead of ashy, and the abdo- men rufous or testaceous. It is also decidedly more slender, the antennas are longer and the spurs on the tibia are very long, extending beyond the tibia by fully half their length. Typocerus oklahomensis Hopping, new species Male. Length 12 mm. Black with four yellow transverse elytral bands and with legs and abdominal segments rufous. Head rather coarsely punctate between the eyes, with rather long tufts of golden vestiture behind the eyes; antennae with segment three longer than four and segments six to eleven with large poriferous areas. Pronotum convex, not inflated on the margins, finely punc- tured, disc covered with golden decumbent pubescence, apical transverse sulcus deep, basal transverse sulcus abrupt and with the usual denser vestiture. Elytra sparsely punctured with four yellow spots or bands, the base narrowly margined with black. Basal band not reaching the lateral margin, second and third nearly reaching the sutural and lateral margins, the apical be- coming mere spots, apices obliquely truncate and emarginate. Female. Length 12.5 mm. Differs from the male only in being slightly more robust, and with the second and third testaceous bands connected at the suture. Holotype, male, bearing the label “Latimer Co., Okla., 12-VI-1931, R. D. Bird.” Allotype, female, bearing the label 34 THE PAN-PACIFIC ENTOMOLOGIST [yoL. XVI NO. 1 “Latimer Co., Okla., 15.VI-1931, R. D. Bird.” Paratypes, six males and two females, all from Oklahoma and all collected by Dr. Ralph D. Bird. Paratypes are deposited in the collection of the Academy of Sciences in San Francisco, the Canadian Na- tional Collection, the University of Oklahoma and that of the author. In the key to the Typocerus in Part I of “The Lepturini of America North of Mexico,” oklahomensis comes near brunni- cornis but the apices of the elytra and general appearance are more like zebratus and badius than any of the other species of Typocerus. Oklahomensis differs from these latter in the finely punctate pronotum, the disc of which is rather densely covered with golden hairs. It also has the testaceous marking of the base of the elytra in the form of a broad band. I have seen one specimen from Florida which seems to be this species. STORED-GRAIN BEETLES IN WESTERN WASHINGTON WITH SPECIAL REFERENCE TO THE TENEBRIONID, CYN7EUS ANGUSTUS LeC. (Coleoptera) BY MELVILLE H. HATCH University of Washington On July 28, 1939, in a flour mill at Seattle, Washington, the following species of beetles were taken: Necrobia rufipes DeG., Dermestes cadaverinus Fab., Lcemophlceus ( Cryptolestes ) ferru- gineus Steph., Lcemophlceus ( Cryptolestes ) pusillus Schon., Cynceus angustus LeC., Tribolium castaneum Hbst., Tribolium confusum Duv., Tenebrio obscurus Fab., Tenebrio molitor L., Ptinus tectus Boisd., Sitophilus granarius L., Sitophilus oryzce L. Of these, the Necrobia rufipes DeG. is not a normal inhabitant of the mill, having been released from an empty ship that had docked at the mill the previous day, having just carried a load of copra from the Philippine Islands to Mexico. The most interesting find was the single specimen of the tenebrionid, Cynceus angustus LeC., taken in meal on the floor of the mill. This species is cited by Leng (Cat. Col. Am. n. of Mex. 1920, p. 234) from Arizona and California and, in addition, is represented in the collection of the United States January, 1940] HATCH— STORED-GRAIN BEETLES 35 National Museum by specimens from Texas and Colorado (C. F. W. Muesbeck in litt.) . In California it occurs about the base of yuccas, according to a letter from Dr. F. E. Blaisdell, to whom I am indebted for the identification of my material. My first Washington specimen was collected at Seattle, May 19, 1928, by a student. My attention was first directed to the species a decade later by a series of over 30 specimens taken in April, 1938, in a house in Seattle. At the same time a specimen was given to me by Mr. Joseph Bruzas, found about a log by one of his high school students at Bothell, just north of Seattle. Two specimens were collected by my students near Seattle in May, 1939, and a single specimen was taken in the laboratory at the University on August 1, 1939. Finally, I have a specimen secured at night at Naches in eastern Washington, July, 1939, in company with Tenebrio molitor L. and other night flying insects. In view of my twelve years’ experience in collecting beetles in Washington, these records look as though we had to do with a recently introduced and rapidly multiplying species and one of possible economic importance. The identification of this species among the Ulominae is not difficult with the aid of Horn’s key and descriptions (Tr. Am. Philos. Soc. XIV (II), 1870, p. 363-364, 369), where the failure of the hind angles of the pronotum to overlap the humeri apparently gets one by the second dichotomy. In the later re- visions of this key (LeConte and Horn, Class. Col. N. A. 1883, p. 381 ; Bradley, Man. Gen. Beetles Am. n. of Mex. 1930, p. 192-193), however, the second dichotomy involves the base of the pronotum being “margined” or “not margined” and is in- valid. Gnathocerus , Cynceus, Tharsus, Alphitobius (in part), and Hypophlceus, among those genera said to have the base of the pronotum not margined, possess a distinct margin, and Eutochia, in which the base of the pronotum is said to be mar- gined, has one species ( picea Melsh.) with it unmargined and the other ( crenata LeC.) with it margined. A noteworthy character of Cynceus angustus LeC., which it has in common with Tharsus , is the prominent canaliculation of at least the posterior portion of the elytral epipleurae. In other genera in which the epipleurae are abbreviated behind, they are either more or less flattened ( Uloma , Metaclisa, Eutochia ) or are narrow and vaguely canaliculate ( Hypophlceus ) . 36 THE PAN-PACIFIC ENTOMOLOGIST [y 0 L.

After the transaction of business, Dr. Duncan announced that the program for the day was a symposium on Palaeoentomology, and introduced the first speaker, Dr. Ralph Chaney, of the depart- ment of Palasontology, University of California. Dr. Chaney spoke upon the fossil insect record. He emphasized the paucity of insect fossils and gave as reasons for the incom- pleteness of the record the following facts: (1) that deposition normally takes place only in the lowlands, (2) that the structure of many insects is unsuitable for preservation, and (3) that only certain types of rock are suitable for insect preservation. He pointed out that apparently ideal conditions prevailed at Floris- sant, Colorado, where the insects were preserved in deposits of fine ash. Dr. Chaney concluded with a few remarks upon the main gaps in the fossil record. The absence of insects prior to the Carboniferous he suggested might be due to the fact that the insects were developing in the uplands, or that they had not yet developed hard parts. The fact that so many of the Carboniferous insects which we know were aquatic was considered a false im- pression resulting from the type of deposition prevailing in that period. Dr. Chaney also pointed out that flower-loving insects are not evident until the Cretaceous although they must have existed long before that era. January, 1940] pacific coast ent. society 37 After a general discussion of Dr. Chaney’s remarks, Dr. Duncan introduced the second speaker, Dr. T. D. A. Cockerell, of Boulder, Colorado. Dr. Cockerell stated that insects were good horizon indicators and that the cockroaches of the various hori- zons of the Carboniferous were different. He also pointed out that except for a few interesting exceptions insects were not found in marine deposits. Among the fresh water deposits he considered Lake Florissant the finest and attributed this fact to the presence of some factor which killed insects in large numbers, possibly fumes from the volcano which deposited the beds of ash. Com- paring the Miocene fauna of Florissant with that of the same area today, he emphasized the fact that there were no tachinid flies then, although they are very abundant now, that tipulids were equally abundant then and now, and that bibionids were far more numerous in the Miocene. Tsetse flies, now found only in equato- rial Africa, occurred in Colorado at that time. In comparing the nearby Green River deposits with those of Florissant, he stated that certain moth-like fulgorids were abundant in the former locality but absent from the latter. Dr. Cockerell then concluded his remarks with an account of a visit to CEningen, where he col- lected some of the insects described by Heer. Following a general discussion, Dr. Duncan introduced the last speaker, Prof. E. 0. Essig, who spoke upon the Pleistocene deposits of California. Prof. Essig stated that in the La Brsea tar pits, most of the insects which had been recovered were beetles, among the most interesting of which were four genera of Carabids, in- cluding Amara and Calosoma, one species of Dytiscus, and a num- ber of tenebrionids, among which were four species of Coniontis and nine species of Eleodes. Most of these beetles represent species still living today. At the McKittrick and Carpenteria deposits, Prof. Essig stated that water beetles and dragonflies prevail. The only truly fossil insect known from California is a dragonfly, which was collected by Dr. Chaney, and described by Cockerell, the two previous speakers. Prof. Essig concluded his talk with a number of stereopticon slides of the La Brsea and Carpenteria deposits as well as insects from these areas. Following the showing of the slides, the meeting was adjourned. — E. G. LinsleiY, Secretary. One Hundred and Fifty-second Meeting, April 9, 1938.

After luncheon about half of the members collected aquatic insects and the others spent the time in social discourse. Although the weather was delightful the season was not very far advanced and the collecting relatively meager. — E. G. Linsileiy, Secretary. One Hundred and Fifty-third Meeting, September 24, 1938. Meeting held at 2 p. m. in the entomological laboratories of the California Academy of Sciences. The following members were present: C. D. Duncan, E. G. Linsley, B. E. White, E. P. Van Duzee, C. D. Michener, J. A. Downes, W. V. Pelle, E. L. Kessel, B. B. Kessel, P. C. Ting, J. 0. Martin, F. E. Blaisdell, E. C. Van Dyke, E. R. Leach, A. E. Michelbacher, S. F. Bailey, H. H. Keifer, G. F. Ferris, E. S. Ross, R. L. Usinger, E. Smith, A. Smith, E. O. Essig, and J. B. Steinweden. Visitors were present as follows: N. Stahler, N. Roberts, P. Pennebaker, J. R. Walker, N. W. Stanger, K. Hagen, and N. E. Good. The minutes of the previous meeting were read and approved. Upon the recommendation of the membership committee the following persons were unanimously elected to membership in the Society: Dr. N. E. Good, Miss Ruth C. Whitney, Mr. J. J. DuBois, and Mr. Nathan Stahler. Dr. Linsley reported for the editorial committee that Dr. Fer- ris, Dr. Blaisdell, and Prof. Essig had been renominated to succeed themselves as rotating members of the committee to serve until 1941. They were unanimously elected by the Society. Dr. Linsley also reported that it was the recommendation of the editorial com- mittee that membership in the Society include a subscription to the Pan-Pacific Entomologist, that the treasurer of the Pan-Pacific Entomologist become the treasurer of the Society, that the annual dues for the Society be $3.00, and that members be billed at the same time as subscribers to the journal, rather than in September, as previously. After a general discussion of the matter, Mr. Martin put the recommendation in the form of a motion, it was seconded, and duly passed by the Society. Dr. Van Dyke called attention to the death of Mr. George Wilson, a long-time, faithful member of the Society. Dr. Van Dyke reminded the group that for a great many years, through the kind efforts of Mr. Wilson, the Society had been enabled to hold its meetings in the offices of the State Department of Agriculture in the Ferry Building. Dr. Van Dyke suggested that a full report of his life be drawn up by someone who knew him well, for incorpora- tion in the Society files. Dr. Duncan asked Mr. Ting to serve in this capacity for the Society. Mr. Steinweden pointed out that short accounts of Mr. Wilson’s life had been published in the Pan-Pacific Entomologist, Journal of Economic Entomology, and Monthly Bulletin of the State Department of Agriculture. January, 1940] pacific coast ent. society 39 Dr. Blaisdell exhibited some very fine drawings of genitalia of Tenebrionidse. He pointed out that the genitalia offered characters of great phylogenetic significance and that a study of these struc- tures revealed that our present classification of this family was unsound. The male genitalia divide the group into two main sec- tions, and also offer characters useful in separating tribes. On the basis of female genitalia, Dr. Blaisdell stated that he was able to distinguish subgenera. Dr. Ferris spoke of his recent trip to Chiriqui Province in Panama. He described the broad, densely forested coastal plain, the high savannah country behind the coastal plain, and the Volcan de Chiriqui, elevation 11,600 ft. On the summit of the volcano Dr. Ferris found many familiar northern plants, including Lupinus, Ceanothus, Castilleia, Vaccinium., Berberis, and Arctostaphylos. In conclusion, he stated that he had returned with a collection of about 450 scale insects, representing perhaps 200 species, a high percentage of which appeared to be new. In response to a question by Prof. Essig, Dr. Ferris stated that aphids appeared to be scarce in the tropics. Mr. Keifer described his work on eriophyid mites, pointing out the apparently large fauna occurring in this State. He said that he had not yet discovered a satisfactory method for making good permanent mounts of his species. Dr. Bailey spoke of his recent trip east in which he visited many entomological institutions and experiment stations and spent some time at Washington studying thrips. Mr. Ting described a similar trip which he had made and spoke of his studies of coleopterous larvae and weevils, particularly Dyslobus. He stated that his studies of both the adults and larvae of the Rhinomacerini convinced him that this tribe belongs in the Anthribidae, rather than in the Curculionidas, near Rhynchites. Mr. Downes reported on his eastern summer trip, which was designed primarily to meet the various entomological workers in the country. He spoke of his journey through the southwest to Florida, of visits to Harvard, Cornell, and the United States Na- tional Museum, and of an auto trip to Ottawa in the company of Dr. Snodgrass. At the conclusion of Mr. Downes’ remarks, the meeting was adjourned. — E. G. Linsley, Secretary. One Hundred and Fifty-fourth Meeting, December 3, 1938.

Simonds, J. D. Gilby, R. A. Smith, and W. Wheeler. The minutes of the previous meeting were read and approved. Mr. Usinger, speaking on behalf of the membership committee, recommended in view of long, faithful, and distinguished serv- ice to the Society that Dr. Edwin C. Van Dyke, Dr. Frank E. Blaisdell, and Mr. Edward P. Van Duzee be given honorary mem- bership. The Society unanimously approved the recommendation although Dr. Ferris deplored the fact that the title was very in- adequate to express the true gratitude, appreciation and respect which the organization feels toward these men. The committee also recommended election to membership of Mr. William Simonds, Mr. Willis Wheeler, Mr. Adolph Rabino- vitch, and Dr. Robert C. Miller. Professor Essig announced with regret the resignation of Mr. Van Duzee after twelve years as editor of the Pan-Pacific Entomo- logist. He also announced that the Publication Committee had appointed Mr. Usinger as the new editor. Upon the suggestion of Dr. Linsley, the Society gave a rising vote of thanks to Mr. Van Duzee for his services. Dr. Michelbacher presented to the Society’s historical files a bound set of letters that he had received from Prof. Essig while the latter was in Europe. Dr. Duncan expressed the appreciation of the Society for this gift. Prof. Essig reported the following nominations for officers for the coming year: President, E. G. Linsley; Vice-President, H. M. Armitage; Secretary, P. C. Ting, and Treasurer, E. R. Leach. The Society unanimously elected these men to office. Dr. Duncan then turned the meeting over to the new officers and Dr. Linsley expressed the appreciation of the Society for Dr. Duncan’s services as president during the past several years. Dr. Linsley then introducd the speaker of the day, Mr. E. S. Ross, who gave an account of his recent automobile collecting trip through Lower California in the company of Dr. and Mrs. A. E. Michelbacher between June 13 and August 10, 1938. Using about one hundred natural color slides of scenery and plant life of the peninsula, generalizations were made on the geographic nature of the peninsula as well as travelling and collecting conditions. Of particular interest were the scenes of the Cape region, an area which had received abundant rains prior to the arrival of the January, 1940] PACIFIC COAST ENT. SOCIETY 41 party. Here plant-life had taken on a spring-like activity with abundant green foliage and many blossoms. As would be expected, insects were secured here in greater numbers than elsewhere on the arid peninsula. About 3000 miles were traveled in Lower Cali- fornia, and nearly 50,000 specimens of insects were secured, many of which will be presented to the California Academy of Sciences. Following Mr. Ross’ talk, Dr. Van Dyke exhibited examples of Brachypsectra which had been taken on the trip and reviewed the interesting history of this rare group of beetles. After a general discussion, the meeting adjourned. — E. G. Linsley, Secretary. One Hundred and Fifty-fifth Meeting, March 4, 1939.

McKenzie, there was a vacancy in the Permanent Historical Committee and the President appointed Professor E. O. Essig to this position. A membership committee was appointed consisting of Dr. Stanley Bailey, Chair- man, Dr. Carl Duncan, Dr. Robert Usinger and Mr. E. S. Ross. An annual field trip committee was also appointed with Dr. A. E. Michelbacher, Chairman, assisted by Mr. Charles Michener and Mr. Arthur Smith. Upon the recommendation of the membership committee, Mr. K. S. Hagen and Mr. R. G. Dahl were elected to membership in the Society. Preceding the main speakers of the day various members and visitors gave short discussions of entomological observations or research under way as follows: Mr. A. Mallis stated that the crazy ant, Prenolepis longicornis, is now established in California and is often found in high-story business buildings. Mr. E. S. Ross displayed an interesting collection of Histeridas from gopher bur- rows including several new species and urged that more collecting 42 THE PAN-PACIFIC ENTOMOLOGIST [yoL. XVI NO. 1 be done in such habitats. Mr. P. H. Timberlake, when asked to discuss his work on the genus Perdita of bees, stated that he had seventy-five species in manuscript, fifty of which are new to sci- ence. He said one hundred and fifty species are known now, primarily from the dry regions, in North America and estimated that from four to five hundred species probably exist in North America. Mr. George Bohart told of his recent studies of Bembix occidentals subsp. beutenmuelleri and displayed parasitized speci- mens from Antioch, California. He gave the following observa- tions concerning the parasites: a Bombyliid fly oviposits near the wasp’s burrow, a Mutillid oviposits in the prepupa, and a Conopid fly oviposits in the adult wasp. Dr. E. G. Linsley spoke of Dr. Carl Duncan’s recent paper on the Vespoid wasps. The main talks of the day formed a Symposium on the Princi- ples of Geographical Distribution, the first speaker being Profes- sor G. F. Ferris. Professor Ferris spoke on distribution and sys- tematics and pointed out that there are two approaches to the subject, namely, the relationship of systematic entomology to dis- tribution and the relationship of distribution to systematic ento- mology. He stated that the distribution of plants and animals falls into patterns with differences due to the age of the groups and that these patterns can be used as a basis for systematic work. Pro- fessor Ferris suggested that a genus is not merely a concept but that it actually exists in nature and the included species are ex- pressions of certain biological factors. He gave as an example, the 525 species of scale insects which have been placed by various authors in the genus Aspidiotus stating that after close study and making allowances for species transported commercially they break up into geographical patterns which are genera. Professor Ferris states that many factors must be considered before con- clusions are formed as to the natural geographical patterns and generic relationships in the Coccidae. Host distribution, the age of the group, and the distribution of related groups are all important factors. Dr. E. G. Linsley spoke on the distributional views of W. D. Matthew emphasizing the following points from his theory: In geological time there has been an alternation of elevations and changes in climate but the ocean bottoms have remained perma- nent. At the present time a rise of six hundred feet would unite all continents into a single mass with the possible exception of Australia and a submergence of six hundred feet would isolate the southern continents. Matthew holds that the most advanced forms will be found in the locality of origin and the generalized forms will be found elsewhere. He suggests that environmental condi- tions migrate and the primitive species follow, while the remain- January, 1940] PACIFIC COAST ENT. SOCIETY 43 ing forms are adapted or become extinct. Matthew also discusses the possibility of over-sea migration by means of natural rafts, pointing out that large masses of floating debris have been ob- served over one hundred miles away from the mouths of such large rivers as the Amazon and Ganges. Dr. E. C. Van Dyke spoke on “Land Bridges.” He pointed out that fossil insects are known from the Paleozoic era and that spiders existed in the Devonian era and it may be assumed that they lived upon insects. Insect fossil remains at present are too few to determine the exact locality of origin for any group. Fossil Mollusca are good indices for periods of geological history, but do not help much in land distributional studies. Dr. Van Dyke sug- gests that too great a significance should not be put on mammal records as insects existed long before mammals appeared. Geologic records show that the northern continents were connected during the Mesozoic era. South America had continental connections only for a very short time. During all of the Paleozoic and two- thirds of the Mesozoic the Panama region was submerged. Many generic groups are restricted to South America and migrated to North America during the Tertiary period. A migration of Euro- pean species to Africa took place during the Pliocene. Dr. Van Dyke believes many small families and genera evolved in South America during the Mesozoic and have remained restricted there. Certain related genera, and occasionally related species, are found in the cave faunas of both the Pyrenees of Spain and in Kentucky. Dr. Robert L. Usinger spoke on the Theory of Continental Drift. He pointed out that this theory is accepted more generally in Europe than in America. Professor Alfred Wegener in 1915 was the first to establish this theory, pointing out that only a slight readjustment is necessary to perfectly fit the opposite Atlantic shore lines of Africa and South America together. Dr. Usinger mentioned a recent book by A. I. Du Toit, “Our Wander- ing Continents,” in which the author considers the absence of marine strata deposits in the east of South America, and in the west of Africa an indication of their being connected. Further evidence of land connection lies in the convincing fact that at least three different fault lines are continuous with each other when the shore lines of eastern South America and Western Africa are matched together. Dr. Usinger further pointed out that the southern tips of Australia, Africa, and India all show evidence of glaciation and that recent measurements of longitude show that the continents have moved during the last one hundred years. The distance moved is said to be greater than that of any probable error in measurements. After a short discussion the meeting adjourned. — P. C. Ting, Secretary. 44 THE PAN-PACIFIC ENTOMOLOGIST [ V QL. XVI NO. 1 One Hundred and Fifty-sixth Meeting, April 21, 1939. Meeting held in the home of Mr. E. R. Leach at 8 p. m.

Douglas, Mrs. E. G. Linsley, and S. E. Flanders. Despite rather poor weather several rather rare insects were collected. Messrs. M. A. Cazier, E. S. Ross and T. H. G. Aitken were successful in taking two species of Cremastocheilus while digging in ants’ nests. Rhinomacer comptus was collected on the staminate cones of digger pine by Dr. E. C. Van Dyke and Nemo- cestes , probably montanus Van Dyke, was collected crawling on the surface of shallow sandstone caves by M. A. Cazier and T. H. G. Aitken. This is the first record of the Curculionid genus N emocestes occurring on Mt. Diablo. — P. C. Ting, Secretary. One Hundred and Fifty-eighth Meeting, September 30, 1939. Meeting held at 2:00 p. m. in the entomological laboratories of the California Academy of Sciences, San Francisco, President E. G. Linsley in the chair. Members present: E. G. Linsley, E. O.

Piazza, Elizabeth Truesdell, Florence Schultz. The Society unanimously elected to membership the following: Mr. 0. B. Cope, Mr. B. Brookman, Mr. J. W. Tilden, Miss Ernestine I. Smith, and Miss Marjorie Poff. The program consisted of brief notes by various members of the Society on summer collecting, new publications, or research under way as follows: Mr. E. G. Linsley exhibited volume I of the new Nomenclator Zoologicus by Sheffield A. Neave which includes a list of generic names used since the time of Linnseus. Professor G. F. Ferris displayed drawings intended to accom- pany a morphological study of the Tipulidas and called attention to need for such work. He mentioned similar studies which were under way on the Mecoptera and Neuroptera. Professor E. 0. Essig described the Yosemite Field School of Natural History with which he has been connected for ten years. The school is limited to twenty students and continues for seven weeks each summer. The first part of the course is devoted to general natural history and the latter part to some specialized ecological study generally at a high altitude. Dr. R. L. Usinger spoke on the conveniences of the school and the excellent oppor- tunity provided for prolonged scientific work in otherwise in- accessible regions. Dr. Usinger made a particular study of the insect fauna of high Sierra lakes and also of the hemipterous genus Platylygus, the species of which are restricted to specific pines. Dr. C. D. Duncan described a summer trip of the Nature Study School of San Jose State College to Mono County, California, where they studied the flora and fauna in some rather recent lakes formed in the bottoms of three different volcanic craters. He suggested that these conditions offered excellent opportunities for ecological studies. Dr. Usinger suggested that perhaps the age of the volcanic craters could be determined from Indian legends in that region. Dr. F. E. Blaisdell reported on the longevity of the tenebrionid, Cryptoglossa verrucosa, which he had maintained for six and one-half years on a diet of rolled oats. Mr. E. P. Van Duzee spoke of the Academy’s recent acquisi- tion of the Graham Hyde collection of butterflies from South Africa. Mr. E. S. Ross, who assisted Dr. E. G. Linsley on the Univer- sity of California summer 49 course at Idyllwild in the San 46 the pan-pacific entomologist [ VO l. xvi no. 1 Jacinto Mountains, California, described the collecting conditions there and told of capturing the rare coccinellid, Coccinella brid- welli Nun. Mr. C. D. Michener mentioned the following intertidal insects which occur at Half Moon Bay, California: A tipulid which ovi- posits at zero tide level with the resulting larvae being submerged in salt water for several hours each day, a eurystethid beetle, several staphylinids and carabids, an ephydrid fly and several chironomids. Dr. N. E. Good described the work of the U. S. Public Health Service on bubonic plague. They maintain four well equipped field trucks which cover all of the western states. All ectoparasites taken from rodents collected in the field are shipped to San Fran- cisco where they are tested on guinea pigs for plague infection. Dr. Good reports that the following western states are infected with bubonic plague: California, Oregon, Idaho, Wyoming, New Mexico and Arizona. — P. C. Ting, Secretary. One Hundred and Fifty-ninth Meeting, December 2, 1939. Meeting held at 2:00 p. m. in the entomological laboratories of the California Academy of Sciences, San Francisco, President E. G.

Dunlop, Mrs. E. P. Van Duzee, C. C. Anderson, G. F. Smith, W. A. Fitschen, W. J. Perry, Florence Schultz, R. Bartges, P. Harvey. Dr. E. G. Linsley announced the death of Dr. H. C. Fall and read a summary of the life of that great coleopterist. It was moved and seconded that the obituary be published along with a picture of Dr. Fall in the next issue of the Pan-Pacific Ento- mologist. It was also moved and seconded that the secretary write a letter of condolence on behalf of the Society to Mrs. Richmond, who is Dr. Fall’s closest living relative. The following were unanimously elected to membership in the Society: Dr. Paul Harvey, Mr. Rex Bartges, and Mr. John W. Johnson. Dr. R. L. Usinger, editor of the Pan-Pacific Entomologist and Mr. E. R. Leach, treasurer, were called upon for their yearly reports. January, 1940] PACIFIC COAST ENT. SOCIETY 47 Professor E. 0. Essig announced the following nominations for officers for the coming year: President, E. G. Linsley; Vice-Presi- dent, H. M. Armitage; Secretary, P. C. Ting; Treasurer, E. R. Leach. The Society unanimously elected these men to office. President E. G. Linsley appointed a new membership com- mittee consisting of Dr. C. D. Duncan, chairman; Dr. M. A. Stewart, and Mr. C. D. Michener. President Linsley also ap- pointed a committee as follows to consider changes in the con- stitution: Professor G. F. Ferris, chairman; Dr. R. L. Usinger, and Mr. E. S. Ross. President Linsley then called attention to Professor Essig’s appointment to the Advisory Committee to the National Research Council; also that Professor Essig will participate in a symposium on the History of Entomology at the coming annual meeting of the Entomological Society of America which is being held at Columbus, Ohio, on December 27-29, in conjunction with the American Association for the Advancement of Science. Mr. E. P. Van Duzee announced, after some discussion, that the entomological laboratories of the California Academy of Sci- ences will now be open on Saturday afternoons for social gather- ings of interested entomologists. Dr. C. D. Duncan exhibited a collection of very fine insect photographs taken by Mr. L. A. Brubaker of San Jose State College. Mr. Dudley Moulton was the first speaker in a symposium on the subject of “Special Methods of Mounting for Temporary and Permanent Preservation of Insects.’’ Mr. Moulton spoke on the technique for study and permanent preservation of Thysanoptera pointing out that the small number of specialists in the Order was due to the difficulty in mounting and studying such minute and delicate winged insects. Mr. Moulton uses an aspirating tube and beating sheet for collecting thrips. His specimens are killed in a solution of glycerin, alcohol, and acetic acid which keeps them pliable until permanently mounted in balsam. He stated that some of his balsam slide mounts of thrips are more than thirty years old and are in perfect condition. Mr. Moulton’s slide collection is arranged in a most systematic manner and is being indexed and correlated by numbers with his library so that all his available material and literature can be brought together within a few minutes. He exhibited several remarkable micro- photographs of thrips and several curious galls formed by these insects. Mr. Moulton has half of the slightly more than four hundred known genera of thrips represented in his private col- lection. Professor E. 0. Essig spoke on the permanency of paper used for insect labels and scientific literature. Many of the very old 48 THE PAN-PACIFIC ENTOMOLOGIST [yoL. XVI NO. 1 books such as the works of Aldrovandus were made of linen rag paper and are still in excellent condition. Most of our literature today is printed on an inferior grade of paper which will prob- ably disintegrate within a few hundred years. He mentioned that the University of California makes a practice of printing several copies of all their publications on the finest grade of linen rag paper. He also suggested the mounting of some of the old more valuable collections of pinned insects on slides to insure their per- manency. He told of the success of the British Museum’s attempts to remount the Walker collection of Trichoptera on slides. He mentioned the desirability of plotting the position of the type speci- men on the slide label when several specimens are mounted on a single slide. Professor Essig houses his own collection of aphids in small boxes of twenty-five slides each. Only a single species is kept in each box which facilitates incorporating additional speci- mens. In this manner it is easy to insert a new box when needed in its proper phylogenetic place. His system is essentially the same as the unit tray system used for pinned insects. In com- ment, Dr. Ferris spoke of some advantages of the envelope sys- tem for filing slides and Dr. Miller exhibited Wistar Institute trays. Dr. M. A. Stewart spoke on the technique used in mounting Siphonaptera. He believes that KOH is the only satisfactory agent for clearing fleas. He punctures the specimen on the mid- ventral line to facilitate the penetration of the KOH. Dr. Stewart mounts his specimens in balsam, a single specimen to a slide, and houses them horizontally on modified Wistar trays. He called at- tention to the fact that in warm climates the specimens will drift in the mounting fluid, if the slides are stored in a vertical position. Mr. H. H. Keifer spoke on the mounting technique for Acarina and Microlepidoptera. He stated that most of the difficulty in making permanent slide mounts of mites is due to their small size. Such minute species as most of the eriophyids cannot be run through several reagents without injury and loss of specimens. The most practical method is to mount them directly in a modi- fied Berlese fluid. One of the ingredients, chloral hydrate, is a very good clearing agent, particularly when slightly heated, but is not a permanent mounting medium. Some of the larger mites can be cleared in KOH and treated in the usual manner. Mr. Keifer mentioned that some of the earlier workers, such as Nalepa and Hotchkiss, dismissed the difficulties of permanent preserva- tion by discarding their specimens after they were described. In discussing Microlepidoptera he mentioned that it is not always necessary to spread their wings, but that it was important to empale them on minute pins soon after they are killed because they do not relax well. — P.

Cauda conical, with 3 (or occasionally 4) hairs on each side, length of hard portion, 0.08 to 0.09 mm.; anal plate circular, armed with about 16 setaa; pro- thoracic and lateral abdominal tubercles as in alate form. Descriptions are from eight alate and seventeen apterous viviparous females mounted on eight slides. A single alate vivi- parous female has been designated as type and is deposited with the California Academy of Sciences in San Francisco. The re- mainder of the specimens are designated as paratypes and are distributed as follows: one slide each in the collections of E. 0. Essig, G. F. Knowlton and M. A. Palmer, and four in the author’s collection. It was suspected that this might be Longicaudus sucedce Mimeur* imported from north Africa on Suceda with rooted date palms, so a slide of the California species was sent to Professor Palmer, who compared it with a slide of Mimeur’s species in her collection. This comparison and a study of Mimeur’s description show that the alate viviparae of the California species differ from those of the African species in having shorter and more cylin- drical cornicles, a smaller cauda, shorter antennae in propor- tion to body lengths, segments III and VI shorter and segments IV and V longer in proportion to total antennal length; fila- ment one-half base of VI rather than more than one-half ; and in having four or five sensoria on III rather than five to eight. Longicaudus is considered by some authors to be a synonym of Pergandeida. *Mimeur, J. M„ 1934. Aphididse du Maroc (Troiseme Note). Memoires de la Societe des Sciences Naturales du Maroc.

NO. 2 ON THE STATUS AND HOME OF ANTHONOMUS GRACILIPES BOHEMAN (Coleoptera, Curculionidge) BY EL WOOD C. ZIMMERMAN Bernice P. Bishop Museum, Honolulu, T. H. The large and widespread genus Anthonomus has not pene- trated Oceania. However, two species of the genus have been reported as inhabiting Pacific islands. One of these is Anthono- mus gracilipes Boheman, 1859, recorded from Tahiti; the other is Anthonomus pumilus Montrouzier, 1860, from the Loyalty Islands. The first of these species is certainly not a Pacific in- sect; the second may be a Pacific insect placed in the wrong genus, but I have not seen it and do not know what it is. Through the courtesy of Dr. A. Roman and the cooperation of the Naturhistoriska Riksmuseum of Stockholm, I have been able to examine a paratype of Boheman’s species recorded from Tahiti, and the results of my study follow. In the report on the “Voyage de L’Eugenie,” Boheman de- scribed Anthonomus gracilipes from “Insula Taiti.” When I first saw this record, I considered that the type specimens were either incorrectly labeled or that Boheman had erroneously assigned some Tahitian weevil to Anthonomus. An examination of a paratype has shown conclusively that A. gracilipes is a typical Anthonomus. It is therefore evident that an error was made in recording the locality of the species. Boheman said that A. graci- lipes was similar to his A. rubricosus, which he described on the preceding page, from “Rio Janeiro,” Brazil. This clue is per- haps sufficient in itself to show that A. gracilipes is a South American insect. However, without additional specimens bearing correct locality data it is not possible to tell to what locality in America the species belongs. It is sufficient to show by this report that A. gracilipes is American and not Tahitian. However, together with his descriptions of A. gracilipes and A. rubricosus, Boheman described a species from Ecuador, one from Uruguay, and one from California. At one of the American collecting points of the cruise, A. gracilipes was collected. We should, therefore, transfer Anthonomus gracilipes Boheman to the Ameri- can fauna (I believe South American) and thus remove another ambiguity and misleading record from the Oceanic coleopterous fauna. The species is redescribed below. APRIL, 1940] ZIMMERMAN— ANTHONOMUS 71 Anthonomus gracilipes Boheman Boheman, Eugenies Resa, p. 132, 1859. Male: derm brownish yellow to reddish brown, the sternum somewhat darker than the elytra, appendages paler ; densely clothed with white squamae.

Legs with the femora loosely clothed with narrow squamae, the fore pair armed with a conspicuous, sharp, acute, triangular tooth at about the apical third, the middle pair armed with a small tooth, hind pair with an inconspicuous, minute, subobsolete tooth; tibiae slender, setose, the fore and middle pair almost straight on the outer side, except for the basal arcuation, sinuous on the inner side, strongly unguiculate, hind pair rather stoutly mucronate ; tarsi with the claws bif ed, the inner teeth con- verging, contiguous distally, almost as long as the outer teeth. Sternum, with the prosternum and coxae densely squamose, the fore coxae contiguous, the postcoxal and antecoxal areas equal in length; mesosternum and coxae densely squamose, the triangular inter- coxal process most densely squamose, the mesocoxae slightly less than one-half as broadly separated as the breadth of a coxa; metasternum finely punctate, densely squamose, evidently some- what more loosely so toward the median line, as long between the mid and hind coxae as the length of the first ventrite along the median line, metacoxae separated about as far as the breadth of a mesocoxa. Venter finely and obscurely punctate, coarsely hirsute; intercoxal process of the first ventrite subtruncate; ventrite I shorter than II plus III. Pygidium , convex, finely punctate, hir- sute. Length: 2.25 mm., excluding the head and rostrum; breadth: 1.1 mm. The paratype at hand bears the labels “Taiti” and “Kinb.” If this were a North American species, it would be placed in the “squamosus” group of the genus. Unfortunately, I do not have access to a collection of South American Anthonomus with which to compare this species and cannot, therefore, place it as an ally of any of the South American species or give a synopsis of diagnostic characters whereby it may be distinguished from them.

APRIL, 1940] LINSLEY AND ROSS— COLEOPTERA 75 RECORDS OF SOME COLEOPTERA FROM THE SAN JACINTO MOUNTAINS, CALIFORNIA BY E. G. LINSLEY AND E. S. ROSS University of California During the latter part of May and June of 1939, the Di- vision of Entomology of the University of California held a summer field course in the San Jacinto Mountains of southern California. A large number of interesting insects were collected in this area and since many of them were new, they will be de- scribed elsewhere. Among the rare or interesting previously described Coleoptera, the following seem worthy of special record: Cupesidae. A number of specimens of the rare Cupes lobi- ceps LeConte, the habits of which are apparently unknown, were taken at Pinon Flats in the early evening of May 22 by sweep- ing miscellaneous low herbage in an open, arid flat. Melasidae. More than twenty examples of the striking beetle Palceoxenus dohrni (Horn), previously known from but a few, scattered localities, were taken in the vicinity of Idyllwild, mostly under bark of old stumps of Libocedrus decurrens. At least one additional specimen was seen flying at dusk. Buprestidae. Acmceodera latiflava Fall is generally treated as a variety of A. hepburni LeConte. However, in a series of more than 500 examples taken at Pinon Flats there was no in- dication of intergradation with the LeConte species. The ma- jority of the specimens were taken under very arid conditions at flowers of Sphceralcea ambigua. When the latter ceased to bloom, they were found on Eriogonum, Encelia, Yucca , and Eriodictyon. In view of the constancy of latiflava and the widely different conditions under which it is found (as compared to hepburni ) it seems probable that it should be considered as a distinct species. Poecilonota bridwelli Van Dyke, a rare species originally described from Imperial County, California, was taken on flowers in a canyon near Palm Springs. Another buprestid, Chrysobothris quadrilineata LeConte, previously known from New Mexico and Arizona, was found on Juniperus calif ornicus at Pinon Flats. 76 THE PAN-PACIFIC ENTOMOLOGIST [yoL. XVI. NO. 2 Coccinellidae. A series of the rare, black, Coccinella pro- longata bridwelli (Nunenmacher) was taken at the type locality (Tahquitz Meadow) in colonies of Aphis lupini Gillette and Palmer on a small perennial lupine. Although the host plant of the aphid was very abundant, colonies of the insect were very scarce and were mostly found at or below the ground level. The beetle was found with but a small percentage of the colonies. According to E. 0. Essig, who very kindly made the determina- tion, the aphid has not been previously recorded from California. Another rare ladybird, Hippodamia lunato-maculata lengi John- son, was taken in numbers on Sphceralcea ambigua at Pinon Flats. Scarabaeidae. The rather uncommon Valgus calif ornicus Horn was found in several localities in the Transition Zone in association with Zootermopsis spp. under bark of Pinas pon- derosa stumps. Cerambycidae. At Palm Springs, Stenodontes ( Notho - pleurus ) lobigenis (Bates) was noticed causing rather severe in- jury to pepper trees along the streets. The larvae mined in the heartwood and over a period of years have succeeded in hollowing out a large proportion of the trees. The weakened trees suffer severely from wind damage. Most of the boring is ip the basal six feet of the trunk, and adults were found resting in the open- ings of their emergence holes in June. The flower-loving longi- corn, Anoplodera ( Judolia ) instabilis (Haldeman), was abund- ant in the higher valleys on lupine, but the individuals repre- sented a black phase similar to that found in the southern Rocky Mountains. Practically all of the males and the majority of the females taken were wholly black, the remainder being much darker than those found in the Sierra Nevadas and farther north- ward. A related but much rarer species, Anoplodera ( Judolia ) scapularis Van Dyke was found in large numbers on flowers of Sphceralcea ambigua at Pinon Flats. Another rare species, Molorchus eburneus Linsley, previously known by single speci- mens from Yosemite and Lake Tahoe, was found on Abies con- color on the Tahquitz Peak Trail. APRIL, 1940] BAILEY— THYSANOPTERA 77 COCOON-SPINNING THYSANOPTERA BY STANLEY F. BAILEY University of California, Davis Among recent findings arising from studies of thrips, there is one of particular interest from the standpoint of the phylogeny of the order Thysanoptera. This fact is the discovery of the cocoon-spinning capacity. Kurdjumov (1913) was the first to report this habit, as observed in the larva of TEolothrips fascia- tus (L.) in Russia. Secondly, unaware of Kurdj umov’s finding, Reijne (1919-20) described the same habit in Franklinothrips tenuicornis Hood in Dutch Guiana (Paramaribo). Lastly, Karny (1926) described the same characteristic in an Anaphothrips species in Java (Buitenzorg) . In the spring of 1932 at Alhambra, California, the writer reared AEolothrips kuwanaii Moulton in the laboratory and dis- covered that it spins a cocoon for pupation. This observation is the first report of this habit among thrips in North America. Since this first observation, the writer has reared AEolothrips fasciatus (L.) and has confirmed Kurdj umov’s finding. These two species have spun their cocoons in curled leaves of alfalfa in vials in the laboratory. In both instances the “silk” came from the anal end of the body and the cocoons were formed by the twisting and turning of the abdomen. The cocoons are not uniform in shape, but usually oval. The “silk” itself varies in diameter. In addition to these species, three others, in two different aeolothripid genera have a similar habit, namely, Orothrips kelloggii Moulton, Ankothrips yuccce Moulton, and Ankothrips gracilis Moulton. All these species secreted the “silk” from the anus* and formed their cocoons in soil in vials in the labora- tory. The cocoons have not yet been found in the field as con- siderable time and patience is necessary to locate them. ♦Snodgrass (1938) states “the Malpighian tubules of certain insects are known to produce just before the time of pupation a substance which is spun out of the anus in the form of silk threads, with which the cocoon is woven. This silk-forming function of the larval Malpighian tubules has been described in the neuropterous species Mermeleon formicarius and Chrysopa period, in the curculionid Phytonomus arator, and in the chalcid Euplectrus bicolor This is apparently the case also in these thrips. 78 THE PAN-PACIFIC ENTOMOLOGIST [ V QL. XVI. NO. 2 In the spring and early summer in California, aeolothripids are very abundant and by midsummer they have largely dis- appeared. Only occasionally is a specimen of /Eolothrips col- lected during the hot, dry period. However at higher elevations they are to be seen during July and August. Orothrips, Anko- thrips, and Erythrothrips in California have only one generation a year and, as far as is known to the writer at present, are all plant feeders. In view of the fact that A Eolothrips fasciatus and kuwunaii (both of which are predaceous) are present over a longer period, it would seem probable that they have two gen- erations (Kurdjumov found two generations in fasciatus) . In- sufficient observations have been made on Dactuliothrips (their larvae have not thus far been collected) to make any definite statement, although the members of this genus almost certainly have the same type of life history as the other aeolothripids in this area. Melanthrips does not occur in North America. Euro- pean records of this latter genus do not mention the pupal stage; the pupa of the very common M. fuscus (Sulzer) is unknown. The collection dates, however, indicate that the seasonal history of Melanthrips (and Rhipidothrips) species is the same as A Eolothrips . Biological data concerning the members of the fourteen other aeolothripid genera are unknown. In the Thripoidea and related groups of Terebrantia the genus Anaphothrips is the only one reported up to this time to exhibit the cocoon-spinning capacity. The species mentioned by Kamy is unknown and to the writer’s knowledge the generic identification was not based on adults. During the spring of 1939 the writer reared large numbers of a Heterothrips col- lected from wild grape flowers, which spun cocoons. This species has only one generation a year. The well-known pear thrips, Tceniothrips inconsequens (Uzel), has a life history (one gen- eration a year) similar to the aeolothripid genera Ankothrips, Orothrips, etc. — at least those known in California. It is to be noted that the larva of T. inconsequens (while not spinning a cocoon) forms an earthen cell with the tip of the abdomen. From intensive collecting and field observations, it is surmised that Odontothrips loti (Hal.) and Oligothrips oreios Moulton, each with one annual generation only, either spin cocoons or form a protective cell in the soil beneath their hosts. APRIL, 1940] DAHL — CICINDELIDiE 79 When the above-mentioned species (with the exception of Anaphothrips ) are examined one is impressed by the fact that they all have tarsal or tibial hooks, or projections on the head or antennae. This is also true of Merothrips species concerning which no life history data are available. From these observations, incomplete as they are, it would appear that the Terebrantia (or at least certain known species which spin a cocoon or form an earthen cell) have developed (or retained) hooks or other anterior projections. These pro- jections doubtless are used in aiding the adult to emerge and are not to be confused with the raptorial function. Also, a gen- eralization which appears to be indicated by these facts is that the cocoon-spinning capacity is a characteristic of the aeolo- thripids and has been retained by certain thripoid representa- tives which have one generation annually. As further biological data is obtained on additional species and new forms are de- scribed, the relationship of the higher groups of the Terebrantia may become more evident. References Karny, H.

NOTES ON SOME CICINDELID^ (Coleoptera) BY RICHARD G. DAHL Oakland, California Since the appearance of the description of Cicindela willi- stoni subsp. amargosce Dahl 1 , several specimens of this form have been collected far from the type locality. It seems desir- able at this time to record this increase in range as well as to sepa- 1 Dahl, R. G., 1939, Bull. Brook. Ent. Soc., 34 : 221-222. 80 THE PAN-PACIFIC ENTOMOLOGIST [yOL. XVI. NO. 2 rate the subspecies from another distantly related form which, however, may he confused with it. Two specimens in the M. A. Cazier collection were collected by Ira La Rivers at Reno, Nevada, in October, 1939. This is approximately 275 miles from the type locality. On May 29, 1939, P. C. Ting, M. A. Cazier, J. A. Downes and T. Aitken, collected eighteen specimens of amargosce on saline flats at Ger- lach, Washoe County, Nevada. And, on May 30, 1939, the same collectors collected five specimens at Cedarville, Modoc County, California. This increases the distance from the type locality, at Furnace Creek, Death Valley, California, to approximately 400 miles; the distance being measured directly between the two points. This known distribution places it as a likely represen- tative of the Great Basin group, as outlined by M. A. Cazier 2 in his review of the willistoni, fulgida , parowana , and senilis groups. The specimens from Gerlach, Nevada, vary slightly from those in the type series in that they are more cupreus. One dark blue-green specimen tends to grade into specimens from Cedar- ville, California, which are dark purple and coal black. The specimens from Reno, Nevada, are entirely coal black, except for white apical elytral spot. The appearance of the black form at once suggests Cicindela plutonica Csy. However, amargosce is readily separable from it by the following characters. In amargosce the labrum is faintly toothed and in all examples available is white. The maxillary palpi vary from glabrous to very sparsely pilose. The black form is sericeous black. The apical spot is wide and always present. The middle transverse band is never present. There is a distinct subsutural row of foveae turning outward apically and joining with a row of dis- tinct marginal foveae. In plutonica the labrum is distinctly toothed, and in a maj ority of the examples studied is black. The first joint of the maxillary palpi is densely pilose, the rest sparsely pilose. The elytra are dull black, with the apical spot thin or almost lacking. The middle transverse band is distinct or indistinct, but always pres- ent. There is a faint subsutural row of foveae, but no marginal foveae. 2 Cazier, 1936, Bull. So. Calif. Acad. ScL, 35 : 156-163. APRIL, 1940] BOHART— LEPTOCHILUS 81 A PRELIMINARY STUDY OF THE SUBGENUS LEPTOCHILUS IN NORTH AMERIC A (Hymenoptera, Vespidas) BY RICHARD M. BOHART University of California, Los Angeles The small and commonly red marked Odynerus of the sub- genus Leptochilus are abundantly represented in North America, where the majority of the species are found in the arid regions of the southwest. However, they are scarce in collections be- cause of their small size and unobtrusive habits. In a previous paper 1 I outlined the characters of the subgenus and redescribed an eastern species, republicanus D. T. The North American Leptochilus can be divided into about a dozen well defined species groups on the basis of structural characters. The present paper includes five of these groups and the others will be treated at a later date. Much of the material used in the preparation of this paper was obtained through the cooperation of the U. S. National Mu- seum, Museum of Comparative Zoology at Harvard, California Academy of Sciences, Academy of Natural Sciences at Phila- delphia, University of Kansas, Washington State College, Oregon State Agricultural College, Colorado State College, and Pomona College. Individuals who were of greatest assistance through loan or donation of specimens were J. Bequaert, P. H. Timber- lake, G. E. Bohart, E. G. Linsley, and C. D. Michener. My attention has been called by Jos. Bequaert to the correct dates of Leptochilus and Par odynerus which I previously cited as 1852 and 1856. Genus Odynerus Latreille, subgenus Leptochilus Saussure.

The four North American species may also be separated on the basis of the male genitalia as figured. Odynerus rufinodus Cresson Odynerus rufinodus Cresson, 1868. Tr. Amer. Ent.

A rare form with black instead of red on the first tergite is known to occur with the red forms in Texas, Wyoming, and California. The subapical hooks of the male aedeagus project sharply back- ward in contrast to those of rufobasilaris. The parameres are similar to those figured for republicanus.

APRIL, 1940] BOHART— LEPTOCHILUS 85 Tylocephalus Group The two North American species comprising this group are distinguished by having a single swelling on the vertex between the posterior ocelli. Also, the second stemite has the median basal suture faint or absent, there is a small sharp tubercle be- tween and above the antennal bases, the propodeum is untoothed, the postscutellum is sharply crested, the female mandible is four- toothed, and the middle femur of the male is depressed beneath toward the base.

NO. 2 In general appearance tylocephalus resembles two other spe- cies from Florida which belong, however, to the subgenus Steno- dynerus. These are histrio Lepeletier and anacardivora Rohwer. The tubercle of the vertex and the lack of pronotal pits easily differentiate tylocephalus. Odynerus monotylus Bohart, new species Male. Black; clypeus, first antennal segment in front, front margin of prothorax, mesopleural spot, band across scutellum, tibiae and tarsi partly, apical margins of first tergite and second segment of abdomen, yellow; tegula reddish; wings dark stained, slightly violaceous, hind wing spotted apically, pubescence pale and short except for rows of long hairs on apices of third to sixth sternites.

APRIL, 1940] BOHART — LEPTOCHILUS 87 The entirely different markings of monotylus should differ- entiate it from tylocephalus. Structurally the two appear to be practically identical. Some specimens of monotylus have more of the abdominal segments banded. Also, the hind margin of the prothorax may be partially yellow-bordered. Minutissimus Group So far this group is known only from a single species which contains the smallest specimens of Odynerus that I have seen. It is structurally similar to the tylocephalus group but lacks the tubercle of the vertex, the sharp tubercle between the antennal bases, and the depressed middle femur of the male, as well as pos- sessing a different type of male genitalia. Odynerus minutissimus Bohart, new species Black; clypeus in male and basal spot of clypeus in female, apex of male antenna beneath, prothorax in front, tegula, meso- pleural spot, band across scutellum, legs partly, apical bands on first tergite and second segment of abdomen, pale yellow; wings smoky and slightly violaceous, apical cell dark. Pubescence short, sparse, and silvery; apical abdominal segments fringed with mod- erately long hairs. Puncturation moderate, punctures mostly about one puncture diameter apart, apices of first two tergites smooth. Third and fourth antennal segments subequal ; male antennal hook reaching base of eleventh segment; clypeus almost as long as broad, shallowly excavated apically; pronotal angles moderate, obtuse; first tergite, and second sparingly, raised apically; second sternite more than twice as long as broad; geni- talia as figured; length to apex of second tergite, male 4 mm., female 5 mm.

However, this group has the second tergite broader than long and the puncturation of the body exceedingly fine. In addition to the single species of the group in North America, I have seen two European species, timidus Saussure and nugdunensis Saussure, which definitely belong to it. The former can hardly be separated specifically from lissosomus but is somewhat more heavily punctured. Odynerus lissosomus Bohart, new species Male.

A Conopid Fly Parasite of Megachile (H ymenoptera, Apoidea) While excavating for Microbembex cocoons in the sand dunes near Antioch, California, October 16, 1938, a dead male Megachile ( Xanthosaurus ) perihirta Cockerell 1 2 was taken from the end of a short burrow in a hard packed sand cliff. No evi- dence of megachilid cells was present which indicates that the bee was occupying a “resting burrow” (a common habit of male bees) when killed by the pupation of the conopid fly parasite, Conops argenti facies Van Duzee 3 within its abdomen. The bee was put in a small vial with a cotton plug. The conopid emerged on March 15 but in a very stunted and unde- veloped condition. — George E. Bohart and John W.

MacSWAIN University of California, Berkeley In the spring and fall of 1938 and 1939 we collected a num- ber of aculeate Hymenoptera from the sandy areas of Emery- ville and Antioch, California. From the former locality several cocoons of the sand wasp, Bembix comata Parker 1 were obtained while at Antioch several hundred cocoons of Microbembex aurata Parker 2 were collected. All of these were brought into the laboratory and opened for examination or placed in bottles for rearing. Of the Bembix comata cocoons examined, about thirty per cent contained the brown silken cases of the chrysidid wasp, Parnopes edwardsii (Cresson) 3 . Approximately the same ratio of parasitism was obtained from unopened cocoons which later emerged. The pupal cases of Microbembex aurata were studied in the same manner and were found to be twenty per cent parasitized by Parnopes westcotti Melander and Brues 4 . In the field neither species of parasite appeared for at least two weeks after the emergence of its host but the parasites re- mained active for as long a period after the bembicids were gone. Parnopes edwardsii , which is a large, brilliant green species, was found to frequent the blossoms of two sweet clovers, Melilotus alba Desr. and Melilotus indicus All. The host wasp also visited these flowers. On cloudy days and at night many of the para- sites remained hidden beneath loose objects on the sand where they often fell victims to the black widow spider, Latrodectus mactans Fabricius, which made its webs in these situations. Parnopes westcotti , a smaller green and bronze wasp, was found most commonly at flowers of the small bush, Croton calif ornicus Mull., which also attracted many Microbembex. 1 Bembix comata Parker, 1917, Proc.

APRIL, 1940] BOHART AND MacSWAIN— CHRYSIDIDJE 93 The habits of both parasites in searching for host cocoons are apparently nearly the same. The activities of Parnopes westcotti were more completely studied because of the relatively large population of that species. A greater concentration of host burrows allowed it a large share of time for actually digging into host entrances. In contrast, Parnopes edwardsii had to search over large areas of sand in order to discover the scattered burrows of its host. While searching, the wasps made short flights close to the sand, alighting frequently to run over the surface, tap rapidly with the tips of their antennae, and examine every depression. At frequent intervals the wasps would scratch the surface of the sand with their anterior tarsi and, upon find- ing what was apparently a host entrance, would tunnel their way beneath the loose top sand. The digging efforts of both species are interesting because of their ineffectiveness. In contrast to other aculeates these wasps have neither well developed man- dibles nor tarsal combs and have restricted use of their front legs. When starting to dig, the body is raised to an almost ver- tical position from which they often lose their balance and fall over backwards. Our observations indicate a striking host specificity for these parasites in the localities studied. At Antioch Bembix comata is scarce whereas Bembix occidentals beutenmuelleri Fox is quite abundant. Parnopes edivardsii is even rarer at this lo- cality than Bembix comata which is, therefore, apparently its only host. In addition, this parasite has never been found in the many cocoons of other Bembix from Antioch which have been examined 5 . Parnopes edwardsii has a wider geographical range than Bembix comata, however, and has been collected on sweet clover at Walla Walla, Washington, in company with Bembix amcena Handlirsch. Parnopes westcotti has not been taken from Bembix cocoons but will most likely be found as a parasite of the common and wide ranging Microbembex monodonata Say, since these two have been collected together in the absence of Microbembex anrata. At Emeryville both species of Micro- bembex are present but are not parasitized by chrysidids. 6 Bohart, G. E., and J. W. MacSwain, 1939.

NO. 2 Fleas of Eastern United States Fleas of Eastern United States. Irving Fox. The Iowa State Collegiate Press. 191 pp. 31 plates. 1940. $3.00. This book is confined to a consideration of the fleas reported from the United States east of the one hundredth meridian ex- clusive of Texas and is apparently a thesis written in partial ful- fillment of the requirements for a doctorate. A good bibliography is given for each species. The specific descriptions are brief but adequate except for the allocation of new species closely related to one or more previously described and for the determination of certain species not earlier reported from the eastern United States. The illustrations are adequate with the exception of the one denot- ing female structures. Unfortunately no fully labeled drawing of a male is given. The absence of entirely satisfactory illustra- tions showing morphologic detail is a serious handicap to a beginning student of Siphonaptera. The locality and host records are as complete as one might reasonably expect in view of the fact that so many of these rec- ords have not been published and therefore are not readily avail- able. The author lists these records under both “Records” and “Eastern localities” which is somewhat confusing until one recog- nizes that the former designation apparently applies only to speci- mens examined by the author and the latter to records made by other workers. Subspecies are either ignored or barely mentioned. Foxella ignotus, for example, is treated as if it were one of several species in the genus rather than the only species with several subspecies. The keys are accurate and clear; however, it would have been more desirable if they had been expanded to include species oc- curring over a wider geographic range. Such an expansion would have done a great deal to eliminate possible confusion arising from the study, with the aid of this book, of new species or species not previously reported from the east. Tunga 'penetrans (L.), despite the statement in the book, has been authentically recorded from Florida and Texas. Opiso- crostis hirsutus (Bak.), Orchopeas labiatus (Bak.), and 0 . nepos (Roths.) occur in the area considered by the author. The allocation of Monopsyllus vison (Bak.) and M. wagneri subsp. to the genus Megabothris is unwarranted. Corrodopsylla has been raised to a generic status; therefore, “Doratopsylla” curvata Roths, is Corrodopsylla curvata. Epitedia testor (Roths.), although described, is not included in the key to the species of Epitedia. Unfortunately no key is given for the genus Ceratophyllus. It is true, as the author indicates, that the characters of species belonging to this genus do not lend themselves as well to a key APRIL, 1940] PRATT— CARABUS TASDATUS 95 as do the species of most other genera, but adequate keys for the species of this genus have been made. In several instances where only one species of a genus is known to occur in the United States, the author writes as if but one species occurs in the east and other species of the genus occur in the west. A synonymic list is included at the back of the book but it is arranged alphabetically according to synonyms. This makes it difficult to find all of the synonyms of a given valid species. A very good list of the eastern fleas arranged according to the hosts from which they have been recorded is given. This book will be very useful in determining described fleas occurring commonly in the eastern United States but its use is very limited as an aid in taxonomic research of this group of in- sects. — M. A. Stewart. CARABUS TCEDATUS FABR. AND ITS SUBSPECIES VAN- COUVERICUS CSIKI OR BICOLOR WALKER ARE IDENTICAL (Coleoptera, Carabidas) BY ROBERT Y. PRATT Coupeville, Washington Carabus ( Archicarabus ) tcedatus Fabr. is listed in Leng’s “Catalogue of North American Coleoptera” as occurring in Alaska. When occurring in the State of Washington it is referred to as the subspecies vancouvericus Csiki 1 * or bicolor Walker 1 . A series of forty-one Carabus tcedatus that I collected within seven days in a single nineteen-acre field on Whidbey Island, State of Washington, have the color of the elytra ranging from brown to distinct black. Comparison of this series with two specimens of the typical form 3 of tcedatus from Kodiak Island, Alaska, and other specimens of Carabus tcedatus in the Hatch collection at the University of Washington, Seattle, conclusively proved that the Kodiak Island and the Washington specimens of tcedatus described as the subspecies vancouvericus Csiki or bicolor Walker were identical. Therefore the subspecies van - couvericus Csiki and bicolor Walker should be relegated to synonymy. 1 Leng, Charles W., Catalogue North American Coleoptera, p. 44, Catalogue No. 169 and 169b, 1920.

Hence the Kodiak Island specimens of tcedatus in the Hatch collection are the typical form. Both the brown and the black elytra are found in Carabus ( Archicarabus ) tcedatus Fabr. from the Alaskan region. HOPLIA MISCELLANY (Coleoptera, Scarabaaidas) BY L. B. BOYER From the descriptions of Hoplia maculifera Moser * 2 3 4 5 and H. philip pensis Moser, 6 one could not surely differentiate between the two species. They might be interpreted as being but scale variations within a single protean species. However, the holo- type of maculifera (number 7225, Philippine Bureau of Science, Entomology) has posterior tarsal claws which are distinctly cleft at the tip while those of philippensis (Holotype number 6026, Philippine Bureau of Science, Entomology) are entire. These insects represent different species. In a recent note 1 the author erred in his interpretation of synonymy in a Central American Hoplia. Whereas he accepted the Junk Catalogue listing “H. argentata Geoffroy” 3 and thus regarded argentata Nonfried 7 a homonym, the Geoffroy insect is argentea, having been described as Scarabceus argenteus \ Therefore, argentata Nonfried is the correct name for the species. In “A Revision of the Species of Hoplia Occurring in America North of Mexico” 2 , the type locality of meridionalis Boyer was omitted. The labels on the holotype read as follows: “Alachua County, Fla., IV-17-1938, F. Young” and “Lake Newman Biol. Station, Gainesville, IV-17-38.” On one group of paratypes the labels are: “Sanford, Fla., Mch. 8, 1927, F. M. Uhler,” and “L. W. Saylor Collection.” The other group of paratypes is labeled: “Meggett, S. C., 26-May-1934, O. L. Cartwright” and “from the 0. L. Cartwright Collection.” ^Boyer, L. B„ Pan-Pac.

The Pan-Pacific Entomologist Vol. XVI, No. 3 July, 1940 A REVIEW OF THE GENUS ANKOTHRIPS D. L. CRAWFORD (Thysanoptera) BY STANLEY F. BAILEY University of California, Davis The present status of the family Melanthripidae has recently been reviewed by the writer (Pan-Pacific Ent. 15 (4) :168-172, 1939). Priesner (1936) has prepared a review of the genus Melanthrips Hal., and Dactuliothrips Moulton is summarized in the first mentioned paper. Dorythrips Hood, and Cranothrips Bagn. each contain at present only one species. The remaining known genus in this family, Ankothrips D. L. Crawford is here reviewed. Through the kindness of Hood, Priesner, Moulton, and the Canadian National Museum, it has been possible to study types, paratypes, or homotypes of all the known species of Ankothrips. Since D. L. Crawford established this distinctive genus in 1909 for rohustus (designated the genotype by Bagnall, 1913) eight additional species have been described. A key to the known species, the description of a new form, and such biological in- formation as is known concerning the California representatives are here presented. Bagnall (1913) placed Dicranothrips Trybom and Priono- thrips Schille in synonymy with Ankothrips. Hood (1924) pointed out the very interesting coincidence that, “In 1909 and 1910 three students of the Thysanoptera, situated in widely sepa- rated parts of the world, described almost simultaneously three species of .ZEolothripidae which were remarkable for certain structural characters previously unknown in the group. Each erected a new genus for the reception of the species known to him; yet, oddly enough, though coming from South Africa, Galicia and California, respectively, these three species were congeneric.” Priesner (1926, p. 86) reviewed the status of the genus up to that date. The same author (1939) reestab- lished Prionothrips as a subgenus for mavromoustakisi Pr. and niezabitowskii (Shille). The outstanding generic characters which separate Anko- thrips from other genera in the Melanthripidae are as follows: The projection of the second antennal segment, the anterior pro- 98 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 3 jection of the vertex, the lack of tarsal claws and tibial spurs, and the transverse horse-shoe shaped sensory areas on antennal segments III and IV. Plate I. Ankothrips.

All other figures in Plates I, II, and III are to same scale as in Plate I, fig. 6, Plate II, fig. 4, and Plate III, fig. 9, i.e., line equals 0.1 mm. JULY, 1940] BAILEY— ANKOTHRIPS 99 The diversity in the genus is not great, although the indi- vidual species exhibit considerable variability when studied in long series. For example, occasional individuals are seen with the antennal projection missing on one or both antennae, the notches or serrations on the antennal projections are variable, and the number of bristles on the pronotum sometimes fluctuates.

In the known males of those species having very heavy bristles on the dorsum of the terminal abdominal segments, namely, cequalis Moulton, robustus D. L. Crawford (Plate II, fig. 4), and notabilis Bailey, there is also variability in the number and placement of these bristles. As the males of more species be- come known the genitalia (Plate II, figs. 5 and 7) will be used more successfully than is now possible. Good specific char- THE PAN-PACIFIC ENTOMOLOGIST [VOL.

It should be noted that the antennal sensory areas on the third and fourth segments do not offer such distinct specific characters as in Melanthrips although there are marked differences (Plate III, fig. 1-10). The nomenclature of the bristles of the pronotum as here used is adapted from Priesner (1936) (Plate I, fig. 3). JULY, 1940] BAILEY— ANKOTHRIPS 101 Key to the Species of Ankothrips 1.

Additional specimens of the type series are in alcohol, as well as a long series of slides from the same locality from manzanita and plum blossoms, February and March, 1935 and 1936. This species has also been collected by the writer from Arroyo Seco, Los Angeles County; on Ceanothus, near Wilbur Springs, Colusa County; on manzanita, at McDonnell Creek, Sonoma County, California. Additional specimens have been collected by R. M. Bohart at Cajon Pass on Ceanothus and by W. A. Brereton in San Gabriel Canyon from “flowers of a woody shrub.” Type locality, Mix Canyon, Solano County, California. Holo- type slide (T16) and allotype (T17) in writer’s collection. The complete life history of none of the species of this genus of thrips has been worked out in detail. However, during the past eight years, the writer has collected and ob- served robustus, gracilis, yuccas , and notabilis in California and a few generalizations can be made regarding their biology. These species have only one generation a year which is corre- lated with the blooming of their native hosts. The earliest species to appear, following the rains of the winter season (in January) is notabilis. Later robustus appears and it may be found up to May at altitudes of about 3,000-4,000 feet. In April, May, and June, yuccce may be found in yucca flowers, particularly in southern California. The preferred host of gracilis appears to be Adenostoma fasciculatum and this thrips is to be found commonly in its flowers in May and June. Judging from these four species, these thrips are plant feeders only. The larvae are 104 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 3 found in the late blooms of the host plants and disappear rapidly as the blooming period passes. The larval period lasts about two weeks. In the laboratory the larvae of yuccce and gracilis have been found to spin cocoons in the soil. Therefore, it is safe to say that in the field pupation occurs in the soil beneath the hosts. The life history of these species may be compared with that of the pear thrips, Tceniothrips inconsequens (Uzel). As in the case of the above-mentioned crop pest, these Anko- thrips species fluctuate greatly in numbers from year to year. When conditions are favorable the larvae of yuccce (Plate II, fig. 3) may be found by the thousands in yucca flowers. The most widespread species in California appears to be robustus ; gracilis and yuccce can be considered common, notabilis common in certain definite, widely-separated localities, and cequalis is rare. The latter species is apparently known only from the orig- inal collection; it may be found to be a coastal species only. Concerning the other two North American species, diffractus and vandykei , nothing is known except the data of the original collections. The exotic species, fissidens, neizabitowskii and mavromou~ stakisi , appear to be common and also occur in numbers in the spring only. Insufficient data are at hand to formulate any general con- clusions relative to the world distribution of this genus. Never- theless, it should be pointed out that in North America this group of thrips is known only from the arid, semi-desert regions. Further and more thorough early spring collecting in other regions having a similar climate in western North America, as well as in South America and Africa, will undoubtedly disclose additional undescribed forms.

ORNITHODOROS TURICATA IN CALIFORNIA (Arachnida, Acarina) BY THOMAS F. KELLEY University of California, Berkeley While working last summer for the George Williams Hooper Foundation for Medical Research, University of California, the writer collected a specimen of a tick which has since been identi- fied as Ornithodoros turicata (Duges, 1876). This is the first time since 1908 that this species has been definitely found in California. The tick was originally described by Duges from Mexico in the newspaper le Repertorio de Guanajuato. Banks in 1908 reported it from Florida, New Mexico, Arizona, and San Diego, California. In the last two instances it was taken from cattle. Several workers including Brumpt (1936), Neveu-Lemaire (1938), and Bishopp (1933) have suggested the presence of this tick in considerable numbers in California, particularly in the southern portion of the state, but as far as can be determined they were evidently making use of Banks’ early publication. At the present time it is also reported to occur in Kansas as well as in the states previously mentioned. The specimen in question, an early nymphal form, was col- lected from the ground squirrel, Citellus beecheyi fisheri Merriam, JULY, 1940] KELLEY— ORNITHODOROS TURICATA 107 at the San Joaquin Experimental Range 20 miles northeast of Madera, Madera County, August 20, 1939. The nymphal tick was brought to the laboratory and reared to the last nymphal stage at which time it was identified by Dr. R. A. Cooley of the Rocky Mountain Laboratory, Hamilton, Montana. This species has been incriminated as a vector of the Texas strain of relapsing fever and has been shown to transmit this hereditarily (Kemp, Moursund, and Wright, 1934). Wheeler (1938) has been successful in experimentally transmitting Trypanosoma cruzi Chagas, the causative organism of Chagas disease, by means of this tick. The presence of this tick so far north in the San Joaquin Valley presupposes a wider distribution in California than has previously been reported. Dr. C. M. Wheeler, of The George Williams Hooper Foundation for Medical Research, has in- formed the writer that he has some specimens of an Ornithodoros tick from ground squirrels in the same locality and from Ray- mond in Madera County. All are in an early nymphal stage and have yet to be identified. If these ticks prove to be Orni- thodoros turicata, it would suggest a wide area of infestation in that region.

KNOWLTON 2 The following report deals with two species of apparently undescribed long-headed flies collected in California during 1939. Thinophilus scopiventris Harmston and Knowlton, new species Male. Length, 5.8 mm.; of wing, 6 mm. Face moderately wide, narrowest just below antennae, greenish, with coarse brownish pollen which is thicker below longitudinal facial ridge; palpi (fig. 2) large, brownish-yellow, each about one and one-half times as large as face and covered with short, stiff, black hairs; front about twice the width of face, coppery-green, except a metallic violet, triangular-shaped, central area immediately below occellar tubercle: the portion of front immediately above antennae and along orbits as far as occiput, lightly dusted with brownish-yellow pollen; antennae black on upper half, yellow below, the third joint short, rounded at tip, the arista inserted near base above; lower orbital cilia and beard composed of stiff, yellowish-white hairs, among which are situated two short, black bristles; upper orbital cilia black. Dorsum of thorax and scutellum dusted with dark brown pollen which hides the greenish ground color except a cen- tral greenish vitta and posterior margin of mesonotum; lateral margins of scutellum shining greenish; one pair of large scutellar bristles outside of which is located a pair of small, hair-like bris- tles; pleurae green, the anterior region dulled with brownish pollen, the posterior surface more greyish; calypters and hal teres yellow, the former with delicate, whitish cilia. Abdomen metallic green with bronze reflections, dusted with grey pollen, the incisures blackish; bristles of thorax and abdomen entirely black; hypopy- gium (fig. 1) black, dulled with greyish pollen, rounded behind, with a pair of large, black, fleshy lamellae, fringed with black delicate hairs which are long and curled at their tips; lamellae reaching ventral hind margin of fourth abdominal segment, this margin not projecting below, but with a cluster of short, stiff bristles. Coxse blackish green, dulled with greyish pollen; fore and middle pairs with coarse black hairs on anterior surfaces, the middle and hind pairs each with a long bristle on outside surface; femora and tibiae brownish, nearly concolorous, yet the former nearly black on upper surfaces; all femora with strong bristles below, the posterior pair with six short bristles along apical half Contribution from the Department of Entomology, Utah Agricultural Expe- riment Station. ^Research assistant and research associate professor of entomology, re- spectively. JULY, 1940] HARMSTON & KNOWLTON — DOLICHOPODIDiE 109 of upper, outer surface; fore tarsi (fig. 3) with last two joints and tips of first three joints, black, their basitarsi somewhat hol- lowed below, with a cluster of stiff bristles at base below and longer hair-like bristles along outer, lower surface; middle tarsi with fifth segment and tips of other segments black; hind tarsi wholly black. (Femora of female lighter than in male.) Wings greyish hyaline, without spots or inf uscations ; third and fourth veins nearly parallel beyond cross vein, the fourth vein ending in apex of wing. Figures 1-3. Thinophilus scopiventris, n. sp., male. Figure 4. Chrysotus xanthocal, n. sp. Described from one male and one female taken at Newark, California, June 27, 1939, by G. F. Knowlton, along the mar- gin of a small stream running through alkaline land. The type is deposited in the collection of the California Academy of Sciences. Taxonomy. In general outward appearance Thinophilus scopiventris , n. sp., resembles T. frontalis V. D., described from Florida; it differs, however, in having a brush of short, coarse bristles on the ventral, posterior margin of the fourth abdominal segment, strong bristles along the lower edge of the posterior femora and in having the legs of much darker color. An in- teresting feature of scopiventris is the striking similarity of structure and color in the fore and middle tarsi with those of T. spinipes V. D., a common Utah species; the latter species 110 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 3 differs, however, in possessing a spot on the last portion of fourth vein and another on the cross vein, also in possessing wholly black femora. Chrysotus xanthocal Harmston and Knowlton, new species Male. Length, 2 mm.; of wing, 2 mm. Face narrow, showing greenish ground color lightly dusted with golden-yellow pollen be- tween approximated eyes; front and occiput green, the former more bronze near middle and above base of antennae; second and third antennal joints black, the latter small, somewhat triangular but with rounded tip, densely pubescent; first joint entirely yellow; arista about two and one-half times length of antenna; palpi (fig. 4) yellow, leaf -like, with two small blackish bristles near their tips; orbital cilia white, about five of the upper ones appearing brownish in certain lights, especially when viewed from behind. Dorsum* of thorax shining metallic green, lightly dusted with yel- low pollen along anterior and lateral margins; pleurae of similar color to dorsum except that pollen is more dense and whitish. Abdomen shining, metallic green with bronze reflections; hypopy- gium more blackish, sub-shining, its appendages entirely imbed- ded; bristles of thorax and hairs of abdomen wholly black. Fore coxae yellow, darkened at base, especially on outer face, their anterior surfaces with whitish hairs which are as long as the thickness of coxae; middle and hind coxae wholly dark, of greenish- black color; femora yellow; fore pair darkened along entire upper edge; middle pair entirely yellow; hind pair yellow with apical fifth blackened; fore and middle tibiae yellow, hind pair brown; all tarsi blackish, without ornamentations; calypters yellow with black cilia; knobs of halteres lemon-yellow, their stems more brownish. Described from one male, taken at Tracy, California, Novem- ber 15, 1939, by F. C. Harmston and V. H. Harmston and de- posited in the collection of the California Academy of Sciences. Taxonomy. This species resembles both Chrysotus terminalis V. D. and C. picticornis Loew. From the former it is readily separated by the yellow palpi and the white hairs of the fore coxae; both palpi and hairs of fore coxae are black in terminalis. From C. picticornis it differs in having large, pendant palpi of a bright yellow color; the palpi of picticornis are small, whitish and lack the two bristles at their tips. Chrysotus xanthocal, n. sp., possesses apical fifth of posterior femora black, posterior tibiae brown, whereas the corresponding structures in picticornis are wholly yellow. JULY, 1940] LA RIVERS— DRAGONFLIES OF NEVADA 111 A PRELIMINARY SYNOPSIS OF THE DRAGONFLIES OF NEVADA BY IRA LA RIVERS Reno, Nevada Although Nevada is an area of almost extreme semi-aridity, still the as yet insignificant number of dragonfly captures within its boundaries have, to the best of my knowledge, yielded the rather substantial number of 63 species. This number is con- sidered substantial because dragonflies are, as a group, re- stricted in their distribution in direct proportion to the available water supply, and Nevada’s water supply probably averages less per unit mile than any other region of equal size in the United States. Only a very small portion of the vast reaches of the state has been collected over, much still remaining to be done along the Nevada-Califomia border, where the western edge of the state meets the tall, humid Sierra, and where, no doubt, many species hitherto accredited only to the coast region will eventually be found crossing the line. A similar situation exists along the Nevada-Idaho and Nevada-Oregon borders, where numerous swift streams head on one of the Great Basin’s northern divides, and flow north and west to the Pacific Ocean via the Snake and Co- lumbia rivers. There is less to be expected along the Nevada- Utah line, since the boundary here is man-made, and stretches across salt flats, playas, and typical desert topographies which present much the same aspect, and contain much the same eco- logic environments, in one state as in the other. The third por- tion of the state with considerable promise for future collecting is the southern tip, bordered on the south and east by the tur- bulent Rio Colorado, up whose broad waters many subtropical dragonflies have worked their way northward from Arizona, Cali- fornia, and Mexico. And last, but not least, is the fourth region of promise, the interior, higher Great Basin ranges such as those in central Nevada bearing the Nevada National Forest. It is the purpose of the author to enlarge upon this list from time to time, as future collecting turns up additional species, until such a time as the accumulation of seasonal and biologic data is sufficient to warrant a more comprehensive synopsis of the state’s dragonflies. 112 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

Edward Payson Van Duzee It is with deepest regret that we announce the death of Mr. Edward Payson Van Duzee at the age of 79 years. Born in New York City on April 6, 1861, he died on June 2, 1940, at Alameda, California, after a brief illness. As a fitting memorial to one who served so long and so faith- fully, the Publication Committee of the Pan-Pacific Entomologist dedicates the October number of the journal to Mr. Van Duzee, one of the founders and editor during the first fourteen years of its existence. The October number will contain a full account of the life and work of Mr. Van Duzee. — R. L. Usinger. 124 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 3 A NEW SPECIES OF CALLIGASTER FROM THE PHILIPPINE ISLANDS (Hymenoptera, Vespidae, Subfam. Zethinas) BY J. BEQUAERT Museum of Comparative Zoology, Cambridge, Massachusetts I have known for some time that the large Zethine wasp from the Philippines, listed thus far as Calligaster cyanopterus, is structurally distinct from the true Javanese cyanopterus. I in- tended to describe it in a revision of Philippine Diploptera. As this revision may be indefinitely postponed, the Calligaster is now described by itself. Calligaster williamsi Bequaert, new species Zethus ( Calligaster ) cyanopterus F. X. Williams, 1919, Rept. Expt. Sta. Hawaiian Sugar Planters’ Assoc., Ent. Ser., Bull. 14, p. 157, figs. 88 (male), 89-94 (nest, egg, pupa). Not of de Saus- sure, 1852. Length (h. + th. + t.l -f- 2) : female, 21 to 26 mm.; male, 20 to 22 mm.; of fore wing: female, 20 to 21 mm.; male, 20 mm. Female. Head in front view (Fig. 1A) more nearly circular than in cyanopterus, conspicuously swollen at vertex and in upper outer orbits. First abdominal segment shaped much as in cyanop- terus, but the ribbon-like portion of tergite (Fig. IB) relatively wider and less parallel-sided, more flattened above and some- what concave basally; first sternite also relatively wider. Phnc- turation much finer and very sparse on frons, vertex and outer orbits (in cyanopterus the punctures of these areas are larger than their intervals) ; also smaller and farther apart along hind margin of pronotum, over mesonotum and scutellum and in lower part of mesopleura. Longitudinal striation of median area of first tergite sharper and more regular than in cyanopterus, spreading fan-like; at base there are seven to ten fine ridges on either side of a conspicuous median ridge; as some of the ridges stop at the margin, new ones appear in the intervals of the re- maining; grooves between ridges 'smooth (punctate in cyanop >- terus). Mid tibiae with two apical spurs (as in cyanopterus). Color of body and wings as in cyanopterus, but the clypeus and mandibles entirely black (in the two females of cyanopterus seen, the apical area of the clypeus and portions of the mandibles are ferruginous) . Male. Differs from cyanopterus in the same details of struc- ture and sculpture as the female. Head (Fig. 1C) not conspicu- ously swollen; apical margin of clypeus more deeply emarginate than in cyanopterus. Thirteenth antennal segment (Fig. ID) JULY, 1940] BEQUAERT— A NEW CALLIGASTER 125 shorter and more broadly rounded off. Clypeus and frons entirely black (in the two males of cyanopterus seen the clypeus bears a small dirty-yellow spot below the middle and there are two dirty- yellow dots on the inter-antennal transverse ridge). C. williamsi seems to average larger than C. cyanopterus. Fig. 1. Calligaster williamsi J. Bequaert: A, head of female; B, first abdominal tergite of female; C, head of male; D, antenna of male. Holotype, female, and allotype, male, Los Banos, Luzon, Phil- ippine Is. (F. X. Williams), Mus. Comp. Zool., Cambridge, Mass. 126 THE PAN-PACIFIC ENTOMOLOGIST [y 0 L. XVI, NO. 3 Numerous paratypes of both sexes at the Philippine Bureau of Science, the Dept, of Entomology of the College of Agriculture at Laguna, P. I., the American Museum of Natural History, the U. S. National Museum, the Academy of Natural Sciences, Phila- delphia, and in Mr. J. van der Vecht’s collection, from Los Banos, Luzon (D. Maulit; P. Bautista; M. M. Manis; A. Coronel; Pedroso; D. Leria, etc.); Zambales, Amuling, Luzon (R. C. McGregor) ; Mt. Maquiling, Luzon (A. Durano) ; Bayombong, Luzon; Lamao, Bataan, Luzon (H. M. Curran) ; Montalban Gorge, Rizal, Luzon (W. Schulze) ; and Puerta Galera, Mindoro (R. P. Cowles). C. williamsi should not be confused with a species of Pare- umenes, of the Philippines (apparently undescribed), of the same color and much the same shape, having even the median longi- tudinal striation of the first tergite. The Pareumenes, however, has long, knife-like mandibles and a quadridentate propodeum. Calligaster de Saussure differs from Zethus in the shape of the first abdominal segment, the tergite of which bears a median dorsal area covered with longitudinal striae. The mid tibiae have two apical spurs in all species I have seen. In the male the antennae have thirteen segments, but the thirteenth is normal, straight, not bent back as a hook nor curled up. The genus is strictly Indo-Malayan. C. cyanopterus de Saussure (1852) is probably restricted to Java, Zethus erythrostomus “Cameron” Meade Waldo (1914) and Calligaster javanus Gribodo (1891) being synonyms; its nest and habits were described by H. 0. Forbes (1885, A Naturalist’s Wanderings in the Eastern Archi- pelago, pp. 72-73), G. E. Frisby (1919) and J. van der Vecht (1934). The supposed cyanopterus recorded from Celebes, by F. Smith (1858), and from Sumatra, by Gribodo (1891), were certainly different and probably undescribed species. C. wil- liamsi is restricted to the Philippines, where its habits were investigated by F. X. Williams (1919). Zethus himalayensis Cam- eron (1904), of Sikkim, and Zethus etchellsii Cameron (1909), of Borneo, the types of which I have seen at the British Museum, appear to be true Calligaster. Both are specifically distinct from either cyanopterus or williamsi. None of the other described Indo-Malayan Zethinae belong in Calligaster. The type of Calligaster is Calligaster cyanopterus de Saussure, by designation of Ashmead (1902, Can. Ent., 24:205). JULY, 1940] MICKEL— LOMACHCETA 127 TWO NEW SPECIES OF LOMACH7ETA, WITH A KEY TO DESCRIBED SPECIES* (Hymenoptera, Mutillidae) BY CLARENCE E. MICKEL University of Minnesota Mr. George E. Bohart, Davis, California, has sent me three specimens, representing both sexes, of a small Mutillid which he states were reared from Larrid cocoons. They proved to be an undescribed species of the genus Lomachceta. Mr. Rollin H. Baker, Austin, Texas, has sent me an additional male speci- men of the same genus collected in northern Mexico. It repre- sents a second undescribed species. The genus Lomachceta was proposed by the author (Ann. Ent. Soc. Amer., vol. 29, pp. 289-295, 1936) . The two new species bring the total number of known species to six. A key to the species is herewith presented to facilitate their identifica- tion. The few observations regarding biology which are avail- able indicate that the species of this genus are parasites of small aculeate Hymenoptera which nest in the twigs of plants.

XVI, NO. 3 THE IDENTIFICATION OF THE FEMALE OF THE MYRMOSID SUBGENUS MYRMOSULA* (Hymenoptera, Tiphiidae) BY CLARENCE E. MICKEL University of Minnesota A revision of the Myrmosinae of the New World by Dr. Karl V. Krombein has recently appeared (Trans. Amer. Ent. Soc., vol. 65, pp. 415-465, January 23, 1940). It includes a key to the males and females of the subgenus Myrmosula and a de- scription of the new species Myrmosa ( Myrmosula ) exagger ata. Since the appearance of this revision, two female specimens of Myrmosula have come to my notice by being included with Mutillid material sent me for identification. The first speci- men was sent me for identification by the Division of Ento- mology, University of California, Berkeley, California. An attempt was made to identify the specimen by means of Krom- bein’s key but due to the use of an unfortunate descriptive term and the absence of any mention of certain structures on the head, authentic identification could not be made. The specimen had been collected at Pasadena, California, and since the only other species recorded from that vicinity was the unique type of exaggerata from Riverside, California, it seemed probable that the specimen was one of that species. The description of exaggerata states: “Frontal processes joined basally to form a weak median biramose process overhanging the bases of the antennae.” The front of the specimen in question was strongly elevated between the insertion of the antennae and the elevation bore a pair of parallel ridges separated by a distance much less than the length of the ridges. It did not seem possible to imagine this elevated prominence as being a biramose process. The same phrase, biramose process, was used in Krombein’s key to de- scribe the interantennal elevation in the species rutilans, except that in that species the biramose process was said to be strong. An examination of rutilans specimens determined by Krombein showed that the interantennal elevation bore a pair of strong oblique ridges, converging but not meeting posteriorly. There was almost no resemblance between the interantennal elevations of the two species, except that both had a pair of ridges, and it did not seem possible to use such a descriptive term as “bira- mose” in describing either one. ♦Paper No. 1793 of the Scientific Journal Series of the Minnesota Agricul- tural Experiment Station. JULY, 1940] MICKEL— MYRMOSULA 133 The Pasadena specimen also had a pair of processes on the under side of the head near the insertion of the mandibles. Nothing whatever was said in the original description of exag- gerata regarding such processes. The specimen was sent to Professor P. H. Timberlake, Uni- versity of California Citrus Experiment Station, Riverside, Cali- fornia, for comparison with the type. Special attention was called to the form of the interantennal elevation and the processes on the under side of the head. Professor Timberlake replied that the type and the Pasadena specimen were exactly alike in all respects, except for a slight difference in color, which he did not regard as significant. A second specimen came in material from the California Academy of Sciences. It was collected at Antioch in Contra Costa County, California. While it is closely related to exag- ger ata it is obviously not the same and is described hereafter. All of the species of Myrmosula have a well developed hypostomal carina. This carina is more or less elevated into a tubercle or a strong process slightly mesad of the insertion of the mandible in all the females of this subgenus so far described. This modification of the hypostomal carina has not been men- tioned with reference to any species in any of the previous papers on this group. The following key is offered with the hope that it may aid in the easier and more certain identification of the known females: 1. Front not elevated between the insertions of the antennas, the antennal tubercles large and prominent; hypostomal carina elevated slightly mesad of insertion of mandibles into a dis- tinct tooth, the latter almost concealed by the mandibular lamella; inferior margin of mandibular lamella emarginate parvula Fox Front very strongly elevated between the antennae, the anten- nal tubercles much less prominent than the interantennal elevation; hypostomal carina very slightly tuberculate slightly mesad of the insertion of mandibles, or with a process not concealed by the mandibular lamella ; inferior margin of mandibular lamella emarginate or not 2 2.

JULY, 1940] LINSLEY — TRAGIDION 135 THE CALIFORNIA SPECIES OF THE GENUS TRAGIDION (Coleoptera, Cerambycidas) BY E. GORTON LINSLEY University of California The genus Tragidion is composed of large, striking, hand- some longicorns, most of the species of which are rare in col- lections. Three species and one subspecies are known to occur in California, but apparently all but one of these have been mis- identified. The following key is offered in an attempt to straighten out these forms. Key to the Species and Subspecies of Tragidion Occuring in California 1. Elytra smooth, not corrugated, costae indicated by vague, thread-like, unraised lines; posterior tibiae slender, sparsely pubescent; dark pubescence without bluish reflections. 2 -.

In this species the antennae are usually but little longer than the body in the male and about three-fourths as long as the body in the female but a small percentage of individuals in any mod- erate series show variation in this character. The most constant structures appear to be the smooth elytra and the form of the posterior tarsi. Type locality: Upper Rio Grande Valley, New Mexico. Distribution: Western Texas to Mojave Desert, California. Host: Yucca. (2) Tragidion gracilipes Linsley, new species Form elongate, subcylindrical; color black, elytra reddish orange, antennal segments three to six reddish in both sexes, pubescence black. Head opaque, finely, closely punctured, the punc- tures perceptibly larger on vertex; vertical carina distinct, shin- ing; vertical horns of male prominent; pubescence short, erect, moderately dense; antennas twice as long as body in male, attain- ing apical one-fourth of elytra in female. Pronotum of male opaque, densely pubescent, with anterior disk very coarsely, more or less contiguously punctured, discal tubercles shining, finely, sparsely punctured, punctures of posterior disk fine, close; pro- notum of female very finely, closely but not contiguously punc- tured, median callous large, polished, with a few fine punctures around margin, discal tubercles polished, with a few coarse punc- tures; prosternum coarsely, subcontiguously punctured in male, finely, closely in female; metasternum and metepisterna finely punctured and pubescent in both sexes; scutellum clothed with black pubescence. Elytra about one and eight-tenths times as long as broad; smooth, costae thread-like, not elevated; surface finely, closely punctured, densely clothed with short, depressed, golden reddish hairs intermixed with fine black hairs on basal margin; apices narrowly, conjointly rounded. Legs elongate; posterior tibiae slender; posterior tarsi sparsely pubescent beneath, seg- ments narrow, first segment longer than following two together, second segment longer than broad, distinctly longer than third segment.

This fine species is related to T. armatum LeConte but differs in the very long antennae of the male (twice as long as the body) and the form of the tarsi in both sexes (sparsely padded beneath with narrow segments, the first longer than the following two together, the second longer than broad and distinctly longer than third). In addition it has an entirely different distribution (foothills rather than desert) and host ( Rhamnus rather than Yucca ) .

'peninsulare Schaeffer, 1908, Bull. Brook- lyn Inst. Arts Sci., 1:339. Tragidion peninsulare, Casey, 1912, Mem. Coleopt., 3:321. This species differs from T. annulatum LeConte (type lo- cality: Sonora, Mexico) by having a narrow dark band at the base of the elytra. The male further differs in having segments eight to eleven of the antennae black, the head, thorax, and legs black rather than reddish brown, and the elytra reddish orange rather than fulvous. A few specimens of what appears to be typical peninsulare have been seen from the deserts of southern California, on Prosopis. The majority of the California forms are smaller, differ in general as indicated in the key, and although occurring from San Diego to Shasta County, are primarily found in the foot- hills and mountains of the northern part of the state on Quercus. These may be regarded as a subspecies, Tragidion peninsulare californicum Linsley, new subspecies. Holotype, female (No. 4605, Calif. Acad. Sci., Ent.), and allotype, male (No. 4606). Additional material has been seen from the following localities: Upper Soda Springs, Shasta County (Van Dyke), Mokelumne Hill, Calaveras County (Blaisdell), Yosemite Valley (Linsley), Sequoia National Park, Tulare County (F. T. Scott), San Ber- nardino Mountains (Linsley), Pasadena (Fenyes), Los Angeles (Linsley), and Poway, San Diego County (Blaisdell). The dates are from June to September. Apparently this is the form which appears in the California lists under the name of “annulatum LeConte.” THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 3 138 THE GENUS CENTRIS IN CALIFORNIA (Hymenoptera, Apoidea) BY P. H. TIMBERLAKE University of California Citrus Experiment Station, Riverside The Californian species of Centris are C. rhodopus Ckll., C. rhodoleuca Ckll., C. pallida Fox, C. ho ff manse ggice Ckll., C. tiburonensis Ckll., C. cockerelli Fox, and the two new species described below. Centris rhodopus is common during the sum- mer on the deserts of southern California, and I have collected a few in Bear Valley (7000 feet), San Bernardino Mountains. One female has been taken at Riverside, but it must have been a stray or wind-blown specimen, as the species almost surely does not nest in the cismontane area. Of Centris rhodoleuca I took three males in Morongo Valley, on Croton calif ornica, August 4, 1933. Centris pallida is common in the spring and early summer on the Colorado desert and near Needles, at flowers of Cercidium, Olneya and Dalea. It has also been taken by C. M. Dammers in the upper portion of Cajon Canyon. Centris ho ff manse ggice occurs on the western part of the Mohave desert and locally in different parts of the cismontane area of southern California. I have taken it at flowers of Lotus scoparius, collect- ing pollen, near Perris. The male has been taken at The Gavilan, Lytle Creek wash and on the Mohave desert near Victorville, on flowers of Pentstemon antirrhinoides, Dicentra chrysantha and Larrea divaricata. Cockerell based his C. ho ff manse ggice davidsoni on a male from Banning, which is like the males recorded above, but it seems to me that the subspecies is based on too feeble characters. Centris tiburonensis is very similar to C. pallida , but smaller. I took both sexes flying with pallida at flowers of Dalea spinosa near Needles, on June 5, 1938. Centris cockerelli occurs rather commonly on the Colorado desert in the spring and early summer at flowers of Cercidium, Krameria and of several species of Dalea. It is certainly the same species as the C. lanosa of New Mexico and southern California (Fox and Cockerell records) , but the male does not quite agree with Cresson’s description of the male from Texas. It is, however, probably not more than subspecifically different from C. lanosa Cress. The types of the following two species are in the collection of the Citrus Experiment Station, Riverside.

DRYOTRIBUS AND MACRANCYLUS ARE NOT AMERICAN COSSONINE GENERA (Coleoptera, Curculionidae) BY ELWOOD C. ZIMMERMAN Bernice P. Bishop Museum, Honolulu, T. H. To one working with American literature, it appears that the genera Dryotribus and Macraneylus of the Cossoninae are American. The purpose of this paper is to call attention to the fact that they are not. In my recently completed report 1 , I had occasion to inquire into the status of these genera, and it is worth while to present my findings to continental students in this more available journal. Genus Dryotribus Horn Dryotribus Horn, 1873, Proc. Amer. Philos. Soc. 13:433. Thalattodora Perkins, 1900, Fauna Haw. 2:146. Synonymy by Champion, 1909, Ent. Mo. Mag. (2) 20:123. This genus was erected by Dr. Horn for the reception of a species ( D . mimeticus ) found in Florida. In 1900 Dr. Perkins named the same insect Thalattodora insignis and based his description upon a single specimen found under a log on the coast of the Hawaiian island of Lanai. In more recent years the species has been found to have a wide distribution and has now been recorded from many places including Florida, West Indies, the main and outlying Hawaiian Islands, Wake Island, Australia, and the Ryukyu Islands, between Japan and Formosa. 1 Zimmerman, E. C. Synopsis of the Genera of Hawaiian Cossoninae with notes on their Origin and Distribution. Occas. Papers, B. P. Bishop Museum, Vol. XV, No. 25, pp. 271-293, 1940. THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 3 142 It is found in numbers breeding in driftwood thrown up on beaches and is evidently confined to such materials. The species D. mimeticus has been considered American and to have been introduced from America to Hawaii. However, enough new data have now been accumulated to refute this theory. In 1916 Dr. Perkins described a second species of the genus from Midway, one of the outlying Hawaiian Islands. In 1925 Sir Guy Marshall described a species from the Sunda Islands, and in 1926 Dr. Perkins described the fourth species from another of the outlying Hawaiian Islands, Pearl and Hermes Reef. These data, I believe, prove beyond a doubt that the genus Dryotribus is a native of the Pacific and that the one species now found in America has been carried there from some part of the Pacific, perhaps Hawaii, through the agencies of man. Both generic and specific synonyms should be added to the Leng Catalogue, and the species should be followed by the sign indicating an introduced species. Genus Macrancylus LeConte Macrancylus Le Conte, 1876, Proc. Amer. Philos. Soc. 14:338. Haloxenus Perkins, 1900, Fauna Haw. 2:148. Synonymy by Champion, 1909, Ent. Mo. Mag. (2) 20:123. LeConte described this genus from specimens taken in Florida by Hubbard and Schwarz. In 1900 Perkins described his Haloxenus , which Champion showed was really Macrancylus , to receive a common insect found under logs and in driftwood on the coasts of the Hawaiian islands of Molokai and Lanai. It is evident that this situation is quite like that of Dryotribus. In my paper on the Guam weevils I described a new species, and when I compared the two previously described members of the genus, M. linearis LeConte and M. immi grans (Perkins) Champion, I found that there were not two species involved but only one with two names. A case of great discontinuity in the natural distribution of the genus was, therefore, eliminated by showing that M. immigrans was a synonym of M. linearis. Fur- thermore the discovery of a new species on Guam showed that Macrancylus , like Dryotribus , is a Pacific genus and not American. I now have a new species from Samoa and one from the Cook Islands. This generic and specific synonymy should be added to the Leng Catalogue, and M. linearis should be marked as an intro- duced species. JULY, 1940] NUNENMACHER— OMUS 143 STUDIES ON THE SPECIES OF OMUS, NO. 1 (Coleoptera, Cicindelidae) BY F. W. NUNENMACHER Piedmont, California Among my captures for the present year, 1939, I recognize what appear to be two new and interesting species of Omus, and take this opportunity to make them known. Omus subcylindricus Nunenmacher, new species Form elongate, parallel and slightly ventricose. Head a little narrower than the widest part of the pronotum, rather coarsely and densely rugulose. Antennae long and slender, a little shorter in the female than in the male. Pronotum as wide as long, widest at apical fourth (5 mm.) ; sides arcuate, straighter posteriorly and moderately convergent toward base, the latter 4 mm. in width; disk rather finely, densely and moderately deeply vermiculate-rugose, the vermiculations very fragmentary and short, in this quite different from all the other species that I have seen or studied. Elytra in the male type 12 mm. long and 6 mm. in width be- hind the middle at posterior third. Sides arcuate from the base, parallel in middle two-thirds, thence arcuately converging to apex, the tip evenly rounded ; disk coarsely and moderately, deeply punc- tured, the punctures becoming more crowded toward and along the sides, without granules, but with a minute short and smooth line at the bottom of each coarse puncture. The only evidence of foveae are a few scattered extra large punctures. Legs rather long. Female. The elytra are 14 mm. in length and 7 mm. in width. Measurements of types. Male: length, 18 mm.; width, 6 mm. Female: length, 20 mm.; width, 7 mm. Type locality: Santa Clara County, California. Variation in the length is from 17 mm. to 22 mm., and the width, 5 to 7 mm. Holotype, male; allotype, female, and twenty-six paratypes in my collection. Nineteen specimens were collected on April 16, 1939; nine others on April 23, 1939. So far I have found this species only in a locality about 400 feet long and 20 feet wide. It has the appearance of an Amblycheila at first glance, the elongate and parallel form being notable. The species belongs to the Lecontei group. Compared with its close allies, lecontei and intermedius, it is more parallel with the vermiculate-rugose sculpturing twice as fine and more crowded than in lecontei. The pronotum of intermedius has 144 THE PAN-PACIFIC ENTOMOLOGIST [yOL. XVI, NO. 3 only traces of such sculpturing. The distribution of this species appears to be very local and it will, in all probability, prove to be a scarce insect in collections. Omus vanlooi Nunenmacher, new species Apparently belonging to the Edwardsi group. The large females look somewhat like that species, but in general the black color is dull or flat and the vermiculate-rugose sculptur- ing will separate the two species. Head a little smaller than the widest part of the pronotum; not so coarsely rugulose as in calif omicus, but more like that in lecontei. Antennas long and slender, slightly different in the two sexes. Pronotum with the sides evenly arcuate to the middle, thence almost straight to the base; surface thickly vermiculate-rugose, but not as deeply so as in calif omicus, more like that in lecontei. Measurements: Length 3.5 mm.; width 4 mm. at the widest point before the middle and 3 mm. at base. Elytra coarsely and densely punctate, with no granules. At the humeri and towards the sides the punctures become deeper and closer. There are no indications of foveae, only here and there a large shallow puncture. Legs rather long. Male. Narrower and less ventricose with the antennae slightly longer and the sides of the elytra less arcuate than in the female. The elytra measure 9 mm. in length and 5 mm. in width. Female. Body broader and more dilated, a little ventricose; elytral apex a little more pointed than in the male and the sides more strongly arcuate. The elytra measure 10 mm. in length and 6 mm. in width. Measurements of types. Male: 15 mm. in length and 5 mm. in width. Female : 16 mm. in length and 6 mm. in width. The paratypes vary as follows: Length 13 to 17 mm., width 5 to 7 mm. Type locality. Butte County, California. Holotype, male, allotype, female, and fifty-six paratypes in the author’s collection. The species is dedicated to W. C. Van Loo.

XVI, No. 4 October, 1940 THE LIFE AND WORKS OF EDWARD PAYSON VAN DUZEE 1 BY E. O. ESSIG and R. L. USINGER University of California Edward Payson Van Duzee was bom at Number 36, East 22nd Street, New York City on April 6, 1861. Perhaps his greatest inspiration during his early years came from his father, William Sanford Van Duzee, a man of remarkable and varied talents and ability, who was a missionary to the Hawaiian Islands with one of the first expeditions in 1837. W. S. Van Duzee was later a dentist, a teacher and a builder and evidently maintained an active interest in scientific work throughout his life. Of his large family, only two sons, Millard C. (Pan-Pac. Ent., 10:90-96, portrait) and Edward P., followed scientific work. In 1861 the elder Van Duzee, whose home was in Buffalo, New York, was engaged as a building contractor in New York City. Within a week after the birth of Edward, the firing on Fort Sumpter initiated the Civil War and necessitated the closing out of building operations and the return of the Van Duzee family to their Buffalo home. Concerning this period, E. P. Van Duzee has written as follows 2 : “My father as soon as he could close up his business in New York returned with his family to his home in Buffalo, and that city and its suburbs was my home for more than fifty years. Before transferring his business activities from Buffalo to New York father had purchased from James Fitz of Brooklyn a large acro- matic refracting telescope, having an eighteen inch objective, that Mr. Fitz had constructed for the University of Virginia and which had been left on his hands through the stress of war conditions then prevailing in Virginia. This instrument is listed in the 8th edition of the Encyclopedia Britannica as one of the three largest refracting telescopes then made. On securing this large instru- ment father sold his smaller one to Hobart College and erected a three-story addition to his home, with the necessary equipment for the equatorial mounting of his large instrument. On the floor be- low the observatory he had five large rooms in which he installed the really extensive natural history collections he had accumulated 1 Read before the 162nd meeting of the Pacific Coast Entomological Society on September 21, 1940. 2 From a short autobiographical sketch of Edward Payson Van Duzee, typed in January, 1940. 146 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 through many years of active scientific work. The largest room was devoted to father’s special interest, the birds, of which a rep- resentative of each species was mounted in a box having a back- ground finished somewhat after the fashion of the habitat groups now so popular in museums. Other rooms contained collections in mineralogy, conchology and miscellaneous subjects. Some of this material he had accumulated while a missionary in the Hawaiian Islands and in travels about the country, and some he had obtained by purchase. These collections and the observatory were open to the public free on certain days each month and father’s place became the rendezvous for those in Buffalo who were interested in Natural History, and it was in these rooms that a few of the more earnest workers in natural science met together and decided to organize the Buffalo Society of Natural Science. Such was the environment in which my boyhood days were spent and it formed, not only in me but also in my older brother, Millard C. Van Duzee, a deep-seated love of nature and a strong collecting diathesis which neither of us ever outgrew. This love of nature was still further strengthened by an intimate association with nature on father’s farm at Lancaster, ten miles east of Buffalo where our summers were spent. There we ran wild in the fields and woods, often accompanying father on his hunting trips for birds and for other objects for his collection. Our education was largely obtained at private schools or under private tutors, but our real scientific training came from actual contact with nature under able guidance, and from the study of nature in father’s large col- lections. Much of my early work was done in botany and geology and a little later in astronomy. In the latter study I devoted my- self largely to work in the observatory, making nightly observa- tions with the telescope, recording sun spots and keeping meteoro- logical records. It was also during this period my duty to preside at the telescope when classes in astronomy were visiting the ob- servatory, and to explain to the students the objects at which they were looking. During all this time, however, my real interest was gradually turning toward entomology under the guidance of Mr. Augustus R. Grote, then the director of the Buffalo Society of Natural Science, and the leading authority on American moths. Mr. Grote encouraged my brother and me to sugar for moths, taught us how to prepare and spread our specimens and helped us by making the determinations of our captures. Millard and I spent many happy days with him. He would exhibit with enthu- siasm some of the new or rare Noctuids he had just received from Belfrage, Behrens, or others of his numerous correspondents, and explain to us the characters distinguishing the new species from allied forms. On one of these visits Mr. Grote advised me to take up the study of some group of insects, and recommended the Hemiptera.” oct., 1940] VAN DUZEE BIOGRAPHY 147 In 1883 William Sanford Van Duzee died and his two ento- mologically inclined sons set out on the course of their life work. Millard carried on as a building contractor while Edward took some special laboratory work from March to July at Yale University under Prof. A. E. Verrill. Here he met and worked with S. W. Williston, one of the leading dipterists of the country. In March of 1885, through Henry A. Ward, an old friend of his father, E. P. Van Duzee became assistant librarian of the Grosvenor Library of Buffalo. This was exclusively a research library and hence provided ideal surroundings for the scientific work which was to occupy most of his waking hours during the next half century. With a medium power monocular microscope and his collection within reach, much of his early work on the Homoptera was done while not actually cataloguing and dis- pensing books at his desk. Other work was done evenings and Sundays in the house which he built at 17 Putnam Street. Here, by his first wife, Julia, were born his son, Edward Heath, who still resides in Buffalo, and his daughter, Mabel, now assistant professor of English at the University of Colorado. During these years, in addition to his work on the Hemiptera, Mr. Van Duzee collected generally, publishing lists of the Lepidoptera and of the dragonflies of Buffalo and vicinity. After ten years he was advanced to head librarian, which position he held for an additional 18 years. During these 28 years he acquired a knowledge of books and bibliographical methods which made him one of the foremost Hemiptera bibliographers of his time. Moreover, on yearly trips to library conventions and while pur- chasing books for the Grosvenor Library, he was able to visit the entomologists at the U. S National Museum and, on at least two occasions in 1885 and 1888, a fellow librarian and the fore- most hemipterologist of America, Philip Reese Uhler of Balti- more. Dr. Uhler was a constant source of inspiration through correspondence and must have welcomed such able assistance because of his own failing eyesight. The first twenty-five years of Mr. Van Duzee’s work covered one of the most productive periods in the history of hemip- terology. Following upon the foundations laid by the greatest hemipterist of all time, Carolus Stal, came such men as E. Bergroth, G. C. Champion, W. L. Distant, 0. H. Heidemann, Geza Horvath, G. W. Kirkaldy, A. L. Montandon, L. Lethierry, B. R. Poppius, and 0. M. Reuter. All of these men are now 148 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 dead, but Mr. Van Duzee actually belonged to their era and his copious letter files, now a part of the historical files of the California Academy of Sciences, contain his regular corres- pondence with these men. Although pursuing a full time librarian’s job Mr. Van Duzee kept constant contact with the field through week-end trips, even during the winter when he often went out in search of hiber- nating forms around Buffalo or at his father’s farm at Lan- caster. This was a fortunate pastime for one confined so largely to clerical work and no doubt contributed to his long life of vigorous activity which never flagged to the very end. Several longer trips were taken during these years of residence in the East and have since become well-known as the type localities of many of his new species. The more important of these trips were to Muskoka Lake, Ontario, Canada, in 1888; Michigan in 1891; Georgia in 1899; Colorado in 1900 and in 1903; the Adirondack Mountains, New York, and to New Jersey in 1902; Ohio in 1905; the Island of Jamaica in 1906; Florida in 1908; the White Mountains of New Hampshire and to Massachusetts in 1909; and to Ottawa and Quebec, Canada, in 1912. Soon after the turn of the century the long and arduous task of writing his catalogue of the Hemiptera was begun. This work went on for about ten years, occupying an increasing amount of his time. The excellent library facilities of the Eastern United States were all available to supplement his own very complete library so the resulting catalogue proved to be an exhaustive treatise and a model or standard of excellence for such biblio- graphical work. While still collecting information, verifying cita- tions (he personally checked each separate reference in the final manuscript) , and untangling the perplexing problems of syn- onymy, the Grosvenor Library had been moved to larger quar- ters and increased to a staff of about fourteen. It is small won- der, under the circumstances, that a nervous condition developed in 1912 which threatened his health and caused him to sever his connections in Buffalo and move West. After a brief visit with his old friend, E. D. Ball in Colorado, he continued on to San Diego where he visited with Mr. J. L. Rose of Alpine. Here he soon recuperated and spent six months collecting Hemiptera in this very nearly virgin field. The results of this work were published in the Transactions of the San Diego Society of Natural History. In 1913 he obtained a position in the library of the oct., 1940] VAN DUZEE BIOGRAPHY 149 Scripps Institution of Oceanography at La Jolla, which position he held through 1914. During this period he was able to resume work on his catalogue and completed a rough draft of the final work. With no apparent prospect of its immediate publication he drew up a check list containing only the names, original ref- erences, and distribution. This was published by the New York Entomological Society and served to validate the many higher group names proposed for the first time. Through Prof. W. E. Ritter, then director of Scripps Institu- tion, Prof. C. W. Woodworth, head of the division of entomo- logoy of the University of California, offered Mr. Van Duzee a position as instructor in entomology at the University of Cali- fornia. The position was accepted in August, 1914, and Mr. Van Duzee immediately applied himself to two tasks, the com- pletion of his catalogue and the building up of the collection of insects at the University. The material which he collected still forms the basis of the University’s insect collection, while his catalogue of 916 pages was accepted by the University of Cali- fornia Press. This monumental work appeared not only as Volume 2 of the University of California Publications in Ento- mology but also as one of the Semicentennial Publications of the University, with a few copies specially bound in this latter series. Teaching never appealed to Mr. Van Duzee and his ac- tivities along this line were limited to field instruction, par- ticularly with the entomological field class of the University of California Summer School which was held at Fallen Leaf Lake in the high Sierra from June 21 to July 31, 1915, under the direction of Dr. E. C. Van Dyke. A report of the many new species collected on this trip and several other important studies on the Hemiptera were published at this time in Volume 1 of the University of California publications in entomology. Mr. Van Duzee lived on Woolsey Street during his early days at the University. After his second marriage he remained for a time in Berkeley and then moved to San Francisco. In the decade since the great fire and earthquake of 1906, the California Academy of Sciences had been gradually rebuild- ing its collections and library. The large insect collections of former years, built up by curators Herman Behr (1862-1867 and 1881-1904), Richard H. Stretch (1868-1880), and E. C. Van Dyke (1904-1916), were completely destroyed but for 300 specimens of type material saved by the courageous action of Miss Alice East- 150 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 wood, curator in botany. This material included the types of the Coleoptera, Hymenoptera, and Hemiptera from the early expeditions to Lower California. With this upon which to build, Dr. Van Dyke carried on for the next ten years in conjunction with his medical practice. Material accumulated during this time included the Grundell collection of about 3,000 specimens, the W. S. Wright collection of about 2,000 specimens, the fine series of insects taken by F. X. Williams on the Academy’s expedi- tion to the Galapagos Islands, numbering about 4,000 speci- mens, the material taken by Mr. Joseph Slevin, mostly in Arizona, by Dr. Thompson in the Orient, and by Dr. Van Dyke from extensive field work throughout the west coast. In all, this ma- terial was estimated by Mr. Van Duzee at about 30,000 speci- mens, a very substantial start toward rebuilding what had been the finest collection of insects in the West. On June 1, 1916, Mr. Van Duzee accepted the positions of librarian and curator of entomology at the California Academy of Sciences. The latter position was open because Dr. Van Dyke had just taken up teaching and systematic work at the University of California. Mr. Van Duzee held the position of assistant librarian of the Academy for eleven years until a full time librarian was employed. For the first seven years he resided on Ninth Avenue in San Francisco near the Academy. Here it was possible to work evenings and in this he was helped by his wife, Mrs. Helen Van Duzee, who assisted him in the library and made a collection of spiders while he was devoting his energies to the Hemiptera. Later they moved to Mill Valley where they built a cabin and lived for one year and then moved to 1212 Fountain Street, Alameda, where the family home is still located. During Mr. Van Duzee’s twenty-four years at the Academy, starting at the age of 55 years, he built another monument to his lifetime of industry and entomological zeal. With the hearty cooperation of the entomologists of the west, the collections grew from 30,000 specimens to well over one million mounted specimens. Five thousand holotypes and allotypes of new species were accumulated and, of even greater importance, this vast amount of material was prepared beautifully and with meticulous care. The best modem technique for handling pinned material was employed with an improved type of unit tray system, glass tops and bottoms on the Lepidoptera cases, and endless details oct., 1940] VAN DUZEE BIOGRAPHY 151 which make the Academy collection one of the neatest and best cared for collections in the world today. It should be emphasized that all of this was accomplished with relatively limited funds and assistance, so that much of the routine fell upon Mr. Van Duzee and the volunteer help of such faithful friends of the Academy as F. E. Blaisdell and E. C. Van Dyke. The favorable conditions at the Academy attracted many large collections which were obtained either by gift or purchase. The largest of these are listed below in the order in which they were received. Specimens E. J. Newcomer collection of Lepidoptera, 1917 1,737 R. H.

During these years Mr. Van Duzee made extensive trips to the San Jacinto Moun- tains in 1917; Siskiyou County in 1918; Huntington Lake in 1919; Washington State and Vancouver Island in 1920; the Gulf of California in 1921; Utah in 1922; Southern California in 1923; Arizona in 1924; Truckee, California, and Nevada in 1927; Fort Collins, Chicago, Buffalo, Ithaca, New York City, 152 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 Boston, Philadelphia, Washington, D. C., Pittsburg, Urbana, Decatur, and Ames, on a trip to attend the Fourth International Congress of Entomology at Ithaca in 1928; and the Owens Val- ley in 1929. Only shorter trips were taken during the next decade because of the failing health of Mrs. Van Duzee’s mother, who required constant attention and care. These short trips took him again to many of his former collecting places in California but much of this travel was incidental to the business of admin- istering the large collections in his care and soliciting new material. Other material accumulated at the academy includes a fine entomological library, obtained by judicious purchases and re- cently augmented by the donation of Dr. Van Dyke’s excellent library consisting of 1,000 volumes and 1,000 separates, bulletins, etc., on the Coleoptera and general entomology and Dr. Isabel McCracken’s library, which is particularly strong in the Hymen- optera. Members of the Pacific Coast Entomological Society had long felt the need for a special entomological journal devoted to western entomology and had actually planned such a journal to be called the “Pacific Coast Entomologist.” However, the un- certainty of conditions during the first World War made the venture inadvisable at that time. In 1924 the project was car- ried through, due to the vision and faith of E. P. Van Duzee, E. C, Van Dyke, F. E. Blaisdell, E. O. Essig, G. F. Ferris, R. A. Doane, Grant Wallace, W. W. Henderson and J. C. Chamberlin. The bulk of the work fell upon the shoulders of Mr. Van Duzee as editor, and Dr. Blaisdell as treasurer, but the entire Publica- tion Committee contributed in no small measure to finance the new venture. To Mr. Van Duzee goes a large part of the credit for the style and standard of excellence which he built up while acting as editor during the first fourteen years of existence of the Pan- Pacific Entomologist. Few people realize the sacrifices of his own research which Mr. Van Duzee made while building this journal up to its present respected position among the entomo- logical journals of the world. Continuing through the year 1938, he never relaxed his editorial vigilance and only turned the work over to others when the pressure of routine duties and fail- ing health forced him to do so. In the latter part of May, 1940, Mr. Van Duzee, accompanied by his wife, drove to Los Angeles where he was occupied with oct., 1940] VAN DUZEE BIOGRAPHY 153 Academy business. While enroute to a collecting place in the Coachella Valley, he was suddenly taken ill and decided to re- turn to his home in Alameda. A trained nurse was employed to accompany them as far as Fresno. Here, after a night’s rest, Mr. Van Duzee’s condition was considerably improved so the nurse was permitted to return to Los Angeles while Mrs. Van Duzee drove her husband home. The following day he entered the Alameda Hospital for observation and rest. Having been informed by his physician that he would be unable to return to his work and being so concerned about the future of the Academy, he called his assistant, E. S. Ross, to his bedside and discussed with him at length the problems having to do with the care of the insect collections. Although appearing to respond imme- diately with hospital care, he died suddenly on the next day, June 2. Funeral services were held Wednesday, June 5, 1940, at 3:00 o’clock p. m. at the Mausoleum Chapel at Mountain View Cemetery, Oakland, in which cemetery he was buried. His funeral was attended by a large group of his entomological friends from all parts of the state. The regular July meeting of the California Academy of Sci- ences was devoted to a commemoration of the life and work of Mr. Van Duzee. The meeting was held in the entomological lab- oratories of the Academy on Wednesday afternoon, July 10, at 4:00 p. m. Short commemorative and appreciative addresses were delivered by E. C. Van Dyke, E. 0. Essig, W. B. Herms, R. C. Miller, and F. M. MacFarland. Mr. Van Duzee will long be remembered for his industry and devotion to the causes for which he worked. Throughout his life are scattered landmarks which will stand as his everlasting monu- ments. He was a link between the older generation of nineteenth century hemipterists and our present-day workers. At the time of his death he was dean of the hemipterists of the world, suc- ceeding to that exalted place upon the death of his friend and correspondent, the eminent Hungarian hemipterist, Dr. Geza Horvath. Prominent as a member and loyal in his support of scientific societies and journals, Mr. Van Duzee was or had been a mem- ber of the following societies: American Entomological Society, American Association of Economic Entomolgists, American Museum of Natural History, Brooklyn Entomological Society, Buffalo Historical Society, Buffalo Society of Natural Sciences, 154 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 Cambridge Entomological Club, Ecological Society of America, Entomological Society of Ontario, Kansas Entomological Society, National Geographic Society, Philadelphia Academy of Natural Sciences, Southern California Academy of Sciences, and Western Society of Naturalists. He was a fellow of the American Asso- ciation for the Advancement of Science, a patron of the California Academy of Sciences, a fellow and charter member of the Ento- mological Society of America and vice-president in 1934, an honored member of the Pacific Coast Entomological Society and a fellow of the San Diego Society of Natural History. During his lifetime Mr. Van Duzee accumulated several sep- arate collections. His Lepidoptera, mostly from Buffalo and vicinity, are now part of the collection of the Buffalo Society of Natural History. The Coleoptera collected in Florida and Jamaica went to his friend H. F. Wickham and thence to the United States National Museum. An extensive collection of Hemiptera, ‘including a full series of his types up to that time,” 3 was sold to Iowa State College in 1897. A large general collec- tion was accumulated for the University of California during the years 1914-1915. Finally his collection of Hemiptera in 1925, including about 30,000 specimens, was given to the California Academy of Sciences and was augmented by approximately 100,000 insects of all orders collected subsequently in general field work by him for that institution. A considerable collection of land shells was likewise accumulated, including some inter- esting species collected by his father in Hawaii in 1837. This collection is a part of the undistributed estate at present. In recognition of his extensive field work while pioneering in little explored territory, a large number of species and two genera have been named in honor of Mr. Van Duzee. Seventy- seven of these are listed at the end of this paper. Mr. Van Duzee published a total of 250 papers, comprising 2821 pages, in the fifty-five years between 1885 and 1940. Dur- ing this period there were only four years at scattered intervals when no papers appeared from his pen. In general, these papers are descriptions of new species, extensive faunal lists, and short notes. A few are monographic treatments of particular groups for North America whereas the check list and catalogue are monumental bibliographical works. In these works he described a total of 895 new species, subspecies, or varieties, 47 new 8 Osborn, Herbert. 1937. Fragments of Entomological History, p. 297. oct., 1940] VAN DUZEE BIOGRAPHY 155 genera or subgenera, 12 new names for species, subspecies or varieties, 5 new names for genera, and 33 higher group names, these last consisting largely of new names for old subfamily or tribal concepts in order to bring the nomenclature of the higher groups of Hemiptera into conformity with that of other orders. A list of all of the names proposed by E. P. Van Duzee is given at the end of this work. The names have been arranged systematically according to the arrangement in his catalogue (1917) for higher groups and alphabetically for genera and species. All names are given in their original form and combina- tion. The number immediately following the name and preceding the colon refers to the bibliographical reference in the complete Van Duzee bibliography at the end of this work, while the num- ber following the colon refers to the page on which the name was proposed. A valuable list of the “Types of genera estab- lished by the author” up to 1909 is given in the Canadian Ento- mologist, 41:380-384. Biographical notes, pictures, and death notices of E. P.

XVI, NO. 4 NEW SPECIES OF HEMIPTERA COLLECTED BY THE TEMPLETON CROCKER EXPEDITION TO THE SOLOMON ISLANDS IN 1933 BY EDWARD P. VAN DUZEE 1 PLATASPIDvE Brachyplatys nitidiceps Van Duzee, new species Closely related to obscurus Montd. from New Guinea; deep polished black; head smooth, polished, eyes bright vermillion red ; a submarginal line on the sides of the pronotum anteriorly, base of costa and abdominal margins yellowish; antennae, ros- trum, tibiae and tarsi ochraceous. Length 6 mm. Head short, almost truncate before, one-half as long as wide betwen the eyes, five-eighths as wide as pronotum across the humeri, its surface smooth and polished, without visible punctures or rugae; cheeks valvate, disk depressed; ocelli small, red, dis- tance between them one-half greater than that to the eye. Pro- notum short, its length three-eighths its humeral width, sides but moderately arcuate the humeri but little prominent; punctures obsolete or nearly so. Scutellum transverse, the ratio of length to width as 11:: 18, one-sixth wider posteriorly; punctures very small, distant, subobsolete, becoming quite so on base and on the lateral areas, especially posteriorly; apex deeply excavated as usual in the males of this genus. Antennal segments as 9:3:10:10:11. Rostrum attaining apex of hind coxae. Ostiolar orifices small, their distance from coxae twice that from sides of the metapleurae, canal narrow, polished, black, flat, with carinate margins, slightly widened and curved anteriorly at apex which attains margin of the opaque area. Venter polished, impunctate, with very feeble transverse rugae; segment VI produced anteriorly in a sharp triangle to apical margin of IV, V being cut through at center. Genital segment truncate at apex, when extended nearly quadrangular if viewed from below, the side margins but little thickened apically; fringe of pale hair on the basal fova forming two hooks, their common median stalk slender, not thickened as in subseneus. Color deep polished black, eyes vermillion red; a submarginal line on pronotum before the humeri, reproduced below, a short vitta on base of elytra, a suggestion of a submarginal line about the apex of the scutellum, an eroded vitta on abdominal margin, a nearly obsolete point behind the stigmata on segments II, III, and IV, and rostrum, pale yellowish; antennae dusky yellow, 1 This posthumous article has been prepared by the editor from the unpub- lished manuscripts of the late E. P. Van Duzee. At the time of his death Mr. Van Duzee was in the midst of a general study of the entire Hemipterous fauna of the Solomon Islands. oct., 1940] VAN DUZEE— SOLOMON I. HEMIPTERA 179 segment I piceous, pale at extreme apex; femora piceous black; tibise and tarsi dusky ochraceous; tip of claws black; whole sternal and pectoral region opaque plumbeous-gray, the outer angle of metapleura only polished black, the acetabula piceous to pale ; base of head beneath with a yellowish spot either side the rostral canal; a very faint castaneous mark discernible on base of scutellum above elytral sinus. Holotype, male, No. 5125, Calif. Acad. Sci., Ent., and one male paratype, taken by Maurice Willows at Uras Cove, Malaita Island, Solomon Islands, May 28, 1933. This species pertains to section “a” in Stal’s synopsis (Enum. Hemipt., V, p. 7, 1876), which includes deplanatus Erich, from the Philippine Islands and obscurus Montandon from New Guinea. It can be distin- guished from deplanatus at once by its nearly impunctate sur- face. It is much nearer obscurus but the puncturation of the scutellum is different, the head wants the feeble rugae, the color markings are much reduced, a character undoubtedly subject to variation, and there are other differences as indicated in the above description. With our present limited knowledge of this group I believe it best to consider it as a distinct species but the study of material from other islands may lead us to place it as a subspecies of obscurus. Pentatomid;e Vitellus ensifer Van Duzee, new species Apparently closely allied to pungens Montr. from the island of Woodlark but differing distinctly in the form of the meta- sternal carina; pale greenish olivaceous, humeral spines rather short, obtuse, slightly recurved. Length 11 mm. Head as long before the eyes as wide between them, broadly sinuate either side, subangularly narrowed anteriorly; tylus scarcely exceeding the cheeks, surface impunctate, transversely wrinkled. Pronotum more than three times as wide across the humeri as long; anterior submargin sulcate, carrying a single row of large confluent punctures that become irregular at the anterior angle; callosities impunctate, the rest of the surface coarsely, sparsely punctate; sides straight, calloused, humeri forming a short nearly terete blunt spine; hind margin deeply sinuate, the posterior angles prominent, rounded. Scutellum as long as broad at base, apex sharply angled above the depressed surface which forms a broadly rounded plate beneath the inner angle of the elytra, disk sparsely, coarsely punctate, the sides 180 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 more finely so, frenum occupying five-sevenths the length of the scutellum. Elytral punctures coarse and discolored on claval region, fine and closer on corium; membrane hyaline. Rostrum long, segment I slightly surpassing the bucculse, II a little longer than III (25::30), IV equal to III. Bucculas widest and obtusely angled anteriorly, their margins sinuate. Prosternal lamina attain- ing apex of first rostral segment, its apex obtusely triangular; its margin broadly sinuate, distally cleft for the reception of the ventral tubercle. Segments I to V of connexivum each armed with a small tooth, VI with an acutely triangular black-tipped spine. Genital segment sinuate next the prominent lateral angles, with a small median notch ; styles linear with an almost knob-like apex that very nearly attains the outer angle of the segment; venter and margin of pleural pieces impunctate, polished. Ostiolar canal long. Color greenish testaceous; antennae apically, and tip of humeral spines and the genital segment slightly infuscated; apex of rostrum and tips of the claws black; ocelli red. Holotype, a unique male, No. 5126, Calif. Acad. Sci., Ent., taken by Maurice Willows at the northwest end of Bellona Island, June 22, 1933. This insect comes nearest to pungens but the shape of the mesosternal lamina will at once distin- guish it. CoREIDjE Amblypelta costalis Van Duzee, new species Pale testaceous-yellow, pronotum posteriorly, scutellum and elytra pale castaneous brown, costa lineate with whitish and black. Length 14 mm. Head shorter than pronotum as 36:: 50, nearly horizontal, ocelli placed midway between median line of vertex and eyes, bucculse as long as dorsal width of head between antennal sockets, highest anteriorly. Rostrum attaining middle of ventral II, seg- ment I attaining margin of prosternum, II as long as I, III shortest, IV longest. Anterior margin of prosternum feebly sinuate, mesosternum feebly sulcate. Antennae a little longer than the entire body, the segments as 65:80:55:68, I slightly thicker apically, feebly triquetrous. Pronotum wider across the humeri than long, 8::5; humeri short-spinose; posterior sub- margin with an abbreviated transverse ruga. Scutellum as long as wide, truncate at extreme apex. Venter feebly sulcate at base. Legs slender, unarmed. Pronotum, scutellum, elytra and pectus closely, coarsely punctate, head obsoletely punctate, venter sha- greened. VAN DUZEE— SOLOMON I. HEMIPTERA 181 Color pale testaceous-yellow, ocelli and eyes reddish; antennal I with tip and an obscure line above blackish, II and III narrowly black at apex, IV blackish with nearly its basal half croceous, the incisure black; basal two-thirds of costa narrowly whitish, limited within by a broader black vitta; membrane fuliginous; extreme tip of scutellum and of the rostrum and tarsal claws black; tibise and tarsi clothed with pale hairs; minute plates at apex of femora black. Genital segment of male with a broad, shallow sinus; plici of sixth ventral of female broadly arcuate, the fissure behind this plica subacute, attaining the plica. Holotype, male, No. 5127, and allotype, female, No. 5128, Calif. Acad. Sci., Ent., and five male paratypes taken by Maurice Willows, Jr., June 22, 1933, at the northwest end of Bellona Island, Solomon Islands. Larger than either bilineata Stal or nitida Stal 2 . LyG^EID.® Scopiastes lepidus ventralis Van Duzee, new subspecies Agrees with Horvath’s description (Ann. Mus. Nat. Hung., 12:631, 1914) in all structural details. Color rufofulvous, eyes black, antennals II and III, posterior lobe of pronotum, elytra, hind margins of propleura, and the meso and metapleura and usually the scutellum infuscated or piceous; antennals IV fulvous or more or less infuscated, scutellum rufous in one specimen, apical two segments of rostrum black; tibise and tarsi sometimes tinged with fuscous. Length 8 mm. Holotype, female, No. 5129, Calif. Acad. Sci., Ent., and two female paratypes taken June 23, 1933, at the northwest end of Bellona Island, Solomon Islands. This can hardly be considered specifically distinct from lepidus , from the same island group, but here the venter is entirely rufo-fulvous, the ostiolar orifices are reddish and the apex of the clypeus is not black. The depth of infuscation on the pronotum, scutellum, elytra, etc. varies from fulvous to piceous but is scarcely blue-black. It is conceivable that this is merely a color form that might be found in a single brood but the chances are that it is a local variation developed on a different island. Dr. Horvath does not state on which island his material was taken. 2 Amblypelta gallegonis Lever (Ann. Mag. Nat. Hist., (10) 17 :324, 1936) is not available for comparison but was described from the Solomon Islands and may be identical with the above. Editor. 182 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 Nysius villicus Van Duzee, new species Allied to ericce but with the sides of the pronotum straight and the antennae more slender. Length, 4 mm. Head strongly punctured, produced between the eyes about as in ericas; black, the pale vittae on clypeus and on each side of it much obscured, especially in male; basal spot small but obvious; cheeks with a pale mark below eyes ; buccuke shorter than in ericae , not attaining base of head, their margins feebly arcuate. Antennae thinner than in ericae; segments in the male as 6:15:13:15; pale tinged with fulvous; IV slightly infuscated, I black above, II blackish at base and apex, III very narrowly so. Pronotum black or blackish, anterior margin obscurely and six longitudinal vittae on posterior lobe more or less distinctly fulvous, the hind margin with a median pale mark as in ericae. Scutellum polished, black, its extreme tip only pale. Base of elytra parallel for about basal fourth, then moderately expanded, nearly parallel beyond the mid- dle; whitish hyaline, the nervures more or less infuscated, the apical margin with three blackish marks that rarely become con- nected. Legs pale yellowish with numerous black points that are larger beneath, tips of tarsi infuscated. Body beneath black, the buccuke and acetabula whitish; metapleura moderately excavated; expanded dorsal and ventral flaps whitish; margins of the pro- and mesopleuras obscurely fulvous. Rostrum attaining hind coxae, segment I barely exceeding bucculae in male, a little larger in female. Venter black, the sides and a subapical discal spot yel- lowish fulvous, more extended in the female. Holotype, male, No. 5130, allotype, female, No. 5131, Calif. Acad. Sci., Ent., and three male and three female paratypes taken at the Tal Lagoon on Malaita Island, Solomon Islands, May 30, 1933. One male and three females taken at Mohawk Bay, Matema Island, in the Santa Cruz group have the sides of the scutellum paler and the membrane longitudinally vittate with fuscous but with so little material I would not feel justified in assigning them even subspecific rank. More material from adjacent islands should be studied. Nysius femoratus Van Duzee, new species Aspect of villicus but differing in the black polished femora and first antennal segment. Length, 3 mm. VAN DUZEE— SOLOMON I. HEMIPTERA 183 Eyes large; head across eyes nearly as wide as basal width of pronotum, 18:: 22; dull fulvous brown, median line anteriorly and a broad lateral vitta next the eyes and beneath black; bucculae low, not quite reaching to base of head, slightly lower posteriorly, narrowly pale. Rostrum attaining hind coxae, segment I hardly surpassing bucculae. Antennae rather short, segment I strongly incrassate for this genus; relative lengths of segments as 6:13:10:12; sides rectilinear, about one-fifth wider at humeri than anteriorly, 22 : : 15 ; brownish fulvous, black anteriorly with median vitta and a mark behind each eye pale; posteriorly black sending a median vitta and another either side to connect with anterior black area; humeri polished black; scutellum black, the extreme tip of smooth median line pale. Elytra whitish hyaline, a spot on inner angle of clavus connecting with the commissure and about three vittse on the corium and radial vein in part fuscous; mem- brane hyaline, a median vitta widened behind fuscous. Beneath black with anterior margin and a lateral spot on propleura, ostio- lar orifice, and some marks exterior to it fulvous brown; posterior metapleural margin narrow, the exterior angle whitish; disk of venter with a pale spot posteriorly. Legs pale testaceous yellow- ish, the femora, except at apex, black, polished, tips of tarsi in- fuscated. Whole surface, elytra excepted, polished, coarsely punc- tate, clothed in part with very minute pale hairs. Holotype, a unique female, No. 5132, Calif. Acad. Sci., Ent., taken on Anuda Island, just east of the Santa Cruz Islands, July 15, 1933. Orthaea oculata Van Duzee, new species Belonging to Stal’s subgenus Diplonotus, section “ss” with the posterior lobe of the pronotum strongly punctate, the anterior lobe shorter than in nigriceps Dallas; castaneous-brown, head black, corium with a large rounded preapical pale spot, legs pale, antennal IV largely white. Length, 6 mm. Head produced, longer than in nigriceps; polished, with minute golden hairs laterally before the antennse; a little narrower than the anterior pronotal lobe, 18:: 21. Pronotum two-thirds as long as humeral width; anterior lobe as long as posterior, its length about one-half its basal width, 10::21, but moderately elevated, with a median band of shallow punctures, otherwise impunctate; collum strongly distinguished, with a single row of punctures; incised line shallow; posterior lobe strongly punctured, with a median line and the humeri smooth. Scutellum strongly punctate, with the usual Y slightly prominent, smooth. Elytra coarsely punctate, the median area nearly smooth, nervures prominent; 184 THE PAN-PACIFIC ENTOMOLOGIST [yQL. XVI, NO. 4 costa narrowly reflexed, its edge minutely serrate. Antennae long, segment I passing tylus by one-half its length; segments as 12:18:21:24. Rostrum attaining hind coxae. Anterior femora less incrassate than in nigriceps, with one subapical spine and two or three setaceous papillae. Color dark chestnut brown; head polished, black; tip of tylus paler; neck under the collum ochraceous either side; hind lobe of pronotum with an ochraceous vitta each side of the median line; reflexed elytral costa, veins more or less, base of corium, a small spot near inner angle and a large rounded one before apex ochraceous or whitish; legs, including coxae, entirely pale yellow- ish; antennae castaneous, narrow apex of segments II and III brown, IV white, the narrow base and apical third brown; beneath black, venter dark brown, rostrum pale. Superior surface nude, except for minute golden pubescence on head anteriorly and por- tions of antennae. Holotype, female, No. 5133, Calif. Acad. Sci., Ent., and one female paratype, taken at Uras Cove, Malaita Island, Solomon Islands, May 28, 1933. In the type the ocular pale spot at apex of corium is very conspicuous, less so on the paratype. Dieuches finitimus Van Duzee, new species In Stal’s key (Enum. Hemipt., IV, p. 161, 1874) this species runs to atricornis Stal but is evidently distinct; black, becoming piceous on the legs and antennae; pronotum and elytra with yel- lowish markings. Length, 7 mm. Head about as in consanguineous, opaque, impunctate. Antennal segments as 16:30:30:30; segment I exceeding tylus by one-half its length. Segment I of rostrum attaining apex of head. Pro- notum nearly as long as its basal width, laminate margins strongly reflexed, scarcely attaining the humeral angles; transverse de- pression deep; anterior lobe moderately convex, impunctate either side of the middle, finely punctate laterally; posterior lobe coarsely punctate. Median area of corium mostly smooth. Anterior femora moderately incrassate with a percurrent double row of short teeth; anterior tibiae widened apically with a few small teeth. Color black, becoming dark castaneous on head and piceous or brown on feet and antennae; median line and two spots either side on hind lobe of pronotum, two discal points on scutellum, a short basal vitta on clavus, a short line on radial vein, a basal line on subcosta, an oblique spot or vitta before apex of corium, and a marginal spot on fourth and fifth connexival segments yellowish; narrow expanded costa to beyond middle and reflexed margin of oct., 1940] VAN DUZEE— SOLOMON I. HEMIPTERA 185 pronotum white, the latter becoming- black over humeri, base of intermediate and hind femora whitish; intermediate tibias and tarsi, anterior at base, antennal I, base and apex of II, and base of III and IV paler brown or yellowish; membrane black. Holotype, male, No. 5134, Calif. Acad. Sci., Ent., a unique taken at Kungava Bay, Rennell Island, Solomon Islands, June 16, 1933. In this species the transverse black elytral band is much obscured by the blackish shade of the elytra. Reduviim: Euagoras crockeri Van Duzee, new species Size and aspect of asseda Stal but paler, rufo-fulvous; posterior lobe of head anteriorly and sometimes anterior lobe as far as base of antennae more or less clouded with fuscous, at times becoming black; antennae fuscous or almost black, segment I longer than head, pronotum, and scutellum together, with a very broad obscure pale annulus before middle and a white subapical annulus as wide as width of anterior lobe of pronotum, segment II one- third as long as I with an obscure paler median annulus, III and IV fuscous, III shorter than I, IV longer. Extreme tip of rostrum darker. Anterior tubercules of pronotum subacuate, directed outward; humeral spines long, directed outward and backward, mostly black; disk between these spines often with a black spot; clavus and inner margin of corium black; membrane fuscous, paler exteriorly; meso and metapleura and sides of ventrals IV and V with a large black spot; tips of femora, tibiae, and tarsi black. The specimens from San Christo val Island differ in having the legs paler, the tibiae and tarsi sometimes scarcely enfumed, the anterior femora usually with a black line, the posterior with two narrow fuscous annuli, one subapical, the other median. These also usually want the blackish discal spot on the pronotum. Length, 15 mm. Holotype, male, No. 5135, and allotype, female, No. 5136, Calif. Acad. Sci., Ent., taken June 22, 1933, by Maurice Willows at the northwest end of Bellona Island; six paratypes and one nymph, same data; one male paratype, wanting the black thoracic spot, taken May 20, Kau Kau Plantation, Guadalcanar Island, by Mr. Willows. Six adults and one nymph from Star Harbor, San Christoval Island, July 1-3, differ only in the color of the legs but this character varies so that the legs may be en- tirely pale. In the typical form of this species the dark head and black knees are conspicuous characters. 186 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 Cercopid^e Genus Clovia Stal This genus is represented in the Solomon Islands by a group of species characterized by a transverse median elytral vitta, usually more or less oblique, at least on the corium, and by an oblique, or almost longitudinal, apical vitta from behind the middle of the costa, toward but not attaining the apex of the elytra, this last usually broken into two maculae of varying size and shape. In most of the species known to me the pronotum and vertex are transversely banded. This group of species is largely represented in New Guinea and adjacent island groups. The genus is found in Africa and over much of Oceanica, at least as far north as the Philippines. A good idea of this group, show- ing the form and pattern of marking, can be had by turning to the Records of the Indian Museum, Vol. Ill, plate 10, figure 9 ( moresbyensis Distant) or the Genera Insectorum, fasc. 143, plate 2, figure 4 ( caput-rance LeGuillon). The five species here described are closely, minutely punctate above, each puncture with a short pale hair. The following key will help to separate these species. 1. Apical pale vitta of corium entire as in caput-ranee fraternus n. sp. -. Apical vitta of corium broken into two spots 2 2. Larger (11.5 mm.); head, pronotum and scutellum black, non- vittate; median elytral vitta transverse lugubris n. sp. -. Smaller (5-9 mm.) head and pronotum transversely vittate....3 3. Head and pronotum pale yellow vittate with brown; scutellum and base of clavus to the transverse vitta also pale clitellaria n. sp. -. Scutellum and base of clavus black or dark brown 4 4. Median elytral vitta strongly oblique, with the broken apical vitta much reduced crockeri n. sp. Median elytral vitta heavier, transverse on clavus, deflected posteriorly on corium; apical vitta forming two broad longi- tudinal vittse, the costal acuminate posteriorly sera n. sp. Clovia fraternus Van Duzee, new species Near antoni and formosula Schmidt. Dark brown; vertex pale croceous with median and subapical vittae; pronotum with one croceous vitta and an entire oblique apical vitta. Length, 7.5 mm. oct., 1940] VAN DUZEE— SOLOMON I. HEMIPTERA 187 Vertex a little shorter than broad between eyes (4::5), more produced than in the other species here described; pale yellow with a broad brown vitta between anterior angles of eyes and a shorter one on superior aspect of front; anterior edge slenderly black. Pronotum brown, darker posteriorly, with a complete bright croceous transverse vitta before middle, hind margin deeply excavated before scutellum, the latter dark brown. Elytra brown, becoming black medianly. Median vitta transverse on clavus, be- coming moderately oblique and contracted to an obtuse point on corium and attaining middle of costal area; apical vitta entire, beginning behind middle of costa, running narrow and straight to beyond middle of corium, its apex broader and bent posteriorly. Face dark brown with a pale median vitta, broad on front and covering most of clypeus; base of front with a bright croceous vitta that passes under eyes, widens on propleura and fades out on mesopleura, this vitta bordered with black which becomes deep polished black behind eyes; base of femora, tibise and tarsi more or less embrowned. Male genital segment a little more than twice as long as its median width, narrowed to an obtuse apex. Holotype, male, No. 5137, Calif. Acad. Sci., Ent., taken on the Island of Santa Catalina, Solomon Islands, July 2, 1933, by Maurice Willows. This insect pertains to the group represented by caput-rance, and seems to find its nearest relatives in antoni Schmidt and formosula Schmidt. From antoni it differs by the immaculate scutellum, in the median vitta not attaining the costa, and in the different genital characters. From formosula it differs in the shorter vertex, the longer median elytral vitta and the shorter and broader genital segment of the male. Clovia clitellaria Van Duzee, new species Apparently allied to polita Schmidt. Elytra ovate, the costa strongly arcuate; pale yellowish, two transverse bands on the vertex, three on the pronotum and much of the elytra blackish; whole of the surface above closely minutely punctate and clothed with short pale hairs. Length, 10 mm. Vertex flat, one-half broader between eyes than long, obtusely angled at apex; a broad black band crossing at anterior angle of eyes, before which is a shorter brown band on reflexed base of front. Pronotum pale yellow with median and apical black bands, the latero-posterior and posterior margins narrowly black. Scutel- lum pale yellow. Elytra blackish fuscous with the following pale yellow areas : base of clavus to apex of scutellum, omitting slender 188 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 scutellar margin, a broad transverse band just beyond, scarcely attaining costa and sometimes connected with claval saddle, nar- rowed from radius to claval suture; apical oblique band broken into two subequal spots; apical submargin of elytra marked by a ferruginous band which includes the apical one-third of the clavus where it is most pronounced. Beneath pale yellow becoming some- what testaceous on front and legs with the following black mark- ings : a slender polished line on base of front, a broken longitudinal vitta behind eyes and another crossing pro- and mesopleuree, apex of rostrum, tarsi above, tips of tibial spines and tibise more or less, embrowned; frontal strias slightly darkened; female oviduct and tips of the male plates also blackened. Tergum apparently largely black. Wings hyaline with fuscous veins. Prothoracic epipleura distinctly wrinkled transversely to eyes. Extreme tip of scutel- lum blackened. Male plates parallel, truncate at apex, one-half longer than wide; valve square at apex, as long as broad. Holotype, male, No. 5138, and allotype, female, No. 5139, Calif. Acad. Sci., Ent., taken at Mohawk Bay, Matema Island, Santa Cruz group, July 10, 1933, and three paratypes taken on Nupani Island, Santa Cruz group, May 8, 1933, by Maurice Willows. One male taken on Guadalcanar Island, Solomon Is- lands, in December, 1920, by J. August Kusche differs in having the elytra browner, the ferruginous apex of the clavus extended broadly onto the corium, the basal “saddle” of the clavus smaller, the oblique yellow apical spots larger and the pronotum ante- riorly longitudinally rugose. Clovia crockeri Van Duzee, new species Pale yellow beneath, fuscous brown above with three pale transverse vittae on the vertex, one on the pronotum, an abbrevi- ated oblique median vitta and two subapical spots placed ob- liquely on the corium. Length, 8.5-10 mm., averaging smaller than clitellaria. Vertex shorter than in clitellaria, its length three-fifths its width between the eyes. More finely punctured above than in clitellaria, the punctures becoming fine transverse rugae on scutel- lum and partially so on pronotum posteriorly; pronotum ante- riorly with a slender but distinct longitudinal carina which in some individuals may become more or less obsolete. Color fuscous brown above, vertex, a transverse vitta before middle of pronotum, a transversely oblique subinterrupted elytral vitta at apex of scutellum running from radial vein almost to commissure and angled at claval suture, and two subapical spots, whitish; vertex OCT., 1940] VAN DUZEE— SOLOMON I. HEMIPTERA 189 with a median transverse vitta and a shorter one on reflexed base of front, brown. Front pale ferruginous with paler lateral striae; basal margin of front black, bordered below by a pale vitta which extends back along sides of pleurae. Legs testaceous-yellow, more or less embrowned, especially on tibiae exteriorly and on tarsi; disk of sternum and venter pale yellow. Tergum, at least later- ally, black. Prothoracic epipleurae very narrow and smooth. Holotype, male, No. 5140, and allotype, female, No. 5141, Calif. Acad. Sci., Ent., taken at Star Harbor, San Christoval Island, Solomon Islands, July 1, 1933, (holotype) and July 3, 1933 (allotype) by Maurice Willows. Paratypes, one female taken with the allotype and another taken at Mohawk Bay, Matema Island, Santa Cruz group, July 8, 1933. These paratypes are slightly larger than the types. The pale brown color, narrow shorter and more oblique median vitta, and the smaller sub- apical spots will most readily distinguish this species. The vestiture and punctation, except as noted, is similar in the species here described. In the present species the male genital segment is shorter and narrower at apex than in clitellaria. Clovia sera Van Duzee, new species Size and aspect of crockeri but more heavily marked with pale, the median elytral vitta transverse across the clavus, the apical vittse heavier. Length, 9 mm. Vertex slightly shorter than its width between eyes, polished black; disk with a blackish band between eyes and a shorter one before this, crossing reflexed base of front. Pronotum, scutellum and elytra blackish fuscous; pronotum with a transverse croceous vitta about its own width behind anterior margin. Elytra with a whitish vitta behind apex of scutellum, transverse across clavus, then oblique, terminating on radial nervure; posterior vitta in form of two elongated spots, the outer lying on costa, its inner margin following radial nervure along which it is produced to a point posteriorly and is as long as width of corium; inner spot forming a longitudinal vitta as long as greatest width of elytron and directed toward elytral apex; an indefinite costal area oppo- site transverse vitta and inner margin behind that vitta to near apex of corium more or less tinged with brown, and with a similar mark against costa exterior to apical vitta. Front and beneath honey yellow; base of front with a concentric pale vitta; tip of rostrum, a lateral vitta next the coxae, tibiae exteriorly and tarsi mostly, black; connexivum and apparently tergum black, polished. 190 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XVI, NO. 4 Holotype, male, No. 5142, Mus. Calif. Acad. Sci., Ent., taken at Uras Cove, Malaita Island, Solomon Islands, May 28, 1933, by Maurice Willows. This species is near crockeri but the markings are broader, the transverse band becoming oblique only as it approaches the radial nervure. The pale color on the vertex and pronotum is more of a croceous and the male genital segment is much longer, more as in clitellaria. Clovia lugubris Van Duzee, new species A large black species, pale beneath, elytra with the usual pale vitta and a castaneous vitta about the apical margin. Length, 11.5 mm. Vertex bluntly angled, distinctly broader between eyes than long (7::5); reflexed base of front more coarsely punctured than rest of upper surface. Above black; short impressed line behind eyes pale as in allied species. Pronotum with a very slender median carina on anterior one-third. Median transverse vitta of elytra whitish, but slightly oblique, terminating on radial nervure; apical spots small, the costal spot one-half its width from costal margin; apical spot about three times as long as costal; apical margin with a castaneous vitta from a little behind transverse vitta almost to apex, the margin slenderly black. Beneath pale yellowish, legs and front more croceous becoming castaneous on front; base of front with a polished pale vitta that is carried back broadly onto mesopleura and is bordered with black. Tibiae ex- teriorly, tarsi and female oviduct black. Holotype, a unique female, No. 5143, Calif. Acad. Sci., Ent., taken at Tal Lagoon, Malaita Island, Solomon Islands, May 29, 1933, by Maurice Willows. This species is quite distinct in its larger size, black color, short nearly straight median vitta and small apical spots on the elytra. FlJLGORIDjE Bennaria venosa Van Duzee, new species Pale testaceous, the elytra whitish with fuscpus veins. Length, 7 mm. to tip of elytra. Vertex transverse, its median length one-half its anterior width, hind margin angularly emarginate, surface somewhat de- pressed, sides carinate, median line slenderly impressed. Front a little more than twice as long as its greatest width, 21 : : 9, sides VAN DUZEE— SOLOMON I. HEMIPTERA 191 strongly, obliquely elevated, median carina wanting; clypeus nar- row, longer than front, median carina prominent; antennal seg- ment II twice as long as wide. Pronotum one-fourth longer than anterior width of vertex; lateral carinse sharp, median obsolete. Mesonotum tricarinate, the median slender. Elytra nearly three times as long as wide, 14: :5, subcostal and inner claval veins weak, others heavy, all obscure close to base. Abdominal appendages two-thirds the length of anterior femora. Male plates as long as py gofer, approximate only at middle; their sides nearly parallel beyond middle, somewhat expanded at their rounded apex. Color yellowish testaceous, tinged with brown on head, meso- notum, and coxae, with some white bloom in places beneath; carinse of head slenderly edged with brown; wings opaque whitish with brown nervures; pale apical margin closely transversely crenulate. Holotype, male, No. 5144, Calif. Acad. Sci., Ent., a unique taken on the northwest end of Bellona Island, Solomon Islands, June 21, 1933. The articulated and apparently moveable ab- dominal appendages are a most remarkable feature of this genus and of Benna Walker. The type of this genus was described from the Philippines and is characterized by a round black spot near the inner angle of the elytra. The genus seems to differ from Benna principally in wanting a median carina on the front. Ricania sigillata Van Duzee, new species Form and general aspect of pulverosa but pale brown with a smaller stigmal spot; elytra with an apical black point and ob- scurely liturate with paler. Length of body, 5 mm., expanse, 17 mm. Head broad as in Euricania tristicula vertex seven times as wide as its median length, without a median carina; front subver- tical above, tricarinate basally; subapical transverse carina not attaining elevated marginal carinse; clypeus ecarinate; pronotum three times as long as vertex, its median carina abbreviated ante- riorly; mesonotum tricarinate, the lateral forked anteriorly as in related species, not attaining margin posteriorly, anteriorly meeting median near pronotal margin. Elytra short triangular, the apical margin equal to claval suture; costal membrane nearly twice as wide as costal areole; radial and subradial nervures straight, parallel, forking from basal cell; costal membrane with about twenty transverse veins to stigma, two obvious lines of transverse veins, anterior to the basal of these transverse lines the two arcuate folds are distinct on disk. 192 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

Holotype, a unique female, No. 5145, Calif. Acad. Sci., Ent., taken by Mr. Willows at Uras Cove, Malaita Island, Solomon Islands, May 28, 1933. This species runs to fumosa in Melichar’s key of 1898 but is quite distinct. Ricania corusca Van Duzee, new species Size of pulverosa but with broader elytra; uniformly polished fuscous brown with a small white stigmal spot. Length to tip of abdomen, 5 mm.; expanse, 16 mm. Head broad as in tristicula; median length of vertex one- seventh its width, no median carina; front transverse, its sides elevated, broadly arcuate; discal carinse complete, connecting with subapical transverse carina, prominent basally, becoming evanes- cent apically; median compartment longitudinally obscurely stri- ate; clypeus ecarinate. Pro- and mesonotum as in sigillata.
