XX, No. 1 January, 1944 APPLIED ENTOMOLOGICAL TAXONOMY* BYH. H. KEIFER Bureau of Entomology and Plant Quarantine State Department of Agriculture, Sacramento, California Governmental, that is tax-supported, institutions are assuming increasing responsibilities for the welfare of the general public. Tax-supported economic entomology is no exception to this, and governmental organizations are the principal places where eco- nomic entomologists find employment. When tax money is spent for arthropod taxonomy in connection with economic organiza- tions, that taxonomy must be the kind that can be directly ap- plied to pest control, because pest control is the chief entomo- logical interest of the tax payer. Thus, most tax-supported tax- onomists work with arthropods as they relate to legislative pest control, surveys, insect eradication, chemical control, and biol- ogical control. He must furnish identifications of species, and bionomical and distributional data. I have been engaged in this type of work for the past fifteen years, and this has given me a considerable opportunity to gain experience with, and to ob- serve, what sort of taxonomic work is required, how adequate the existing taxonomic literature is, how specialists in this subject meet their problems, what attitude these taxonomists take toward their work, and how the institutions that need this work support their taxonomists. From this experience I have developed the conviction that applied taxonomy can have more definite objectives than it now seems to show, with resulting benefits to economic entomology. But the responsibility and vision for maintaining such objectives must rest largely in the organizations hiring taxonomists. We may define applied taxonomy as that portion of arthropod classification dealing with the specific identification in and the bionomical coordination of, anthropod groups containing spe- cies in competition with or dangerous to the human animal; or in groups which contain species that help control effectively the * Presidential address read before the Pacific Coast Entomological Society on DecembtFr 18, 1943. 2 THE PAN-PACIFIC ENTOMOLOGIST [yoL. XX, NO. 1 harmful kinds. In other words, this form of taxonomy is a re- stricted activity. Arthropod groups having the greatest number of important species receive the most attention, with those having fewer important species receiving proportionately less. Taxonomy in its broadest and most fundamental aspect is principally the search for facts bearing on the origin of, and interrelationships and differences between, organisms and groups of organisms. Any restriction of taxonomy such as that here treated, must rest on the fundamentals. Our gauge, as to the direction in which the energies of ap- plied taxonomy are expended, rests on evaluating each group of arthropods according to the number of economic species it con- tains. I use the word group because taxonomy is a science of comparison, and the taxonomist knows important species thor- oughly only after he has carefully compared them with all similar species. Thus, a group may be anything from a portion of an order to part of a family. For example, a worker who compares and describes species in the scale insect group, continually sharpens his wits on identifying a considerable number of eco- nomic species. Opposed to this, a person studying dragonflies could not, by that activity, identify any economic species. This does not mean that the taxonomy of dragonflies, mayflies, and other groups we might mention, is worthless. Such studies ob- viously have a definite place in entomology, but are inappro- priate when supported by economic organizations. The most important activity of the applied taxonomist is the identification of species. In taxonomy which seeks the funda- mentals of arthropod correlation, the identification of species may well be of secondary significance. But in economic entom- ology the identification of an important species is the key to the situation. It is the first step of an economic operation. It gives the control man access to the past literature on the pest, and enables the orderly recording of new data. Our most notable recent example of the role of taxonomy in economic operations is the identification of a single caterpillar from Orange County (California) in October, 1942, as the larva of the oriental fruit moth. There followed many meetings of fruit growers and en- tomologists consuming considerable time and traveling expense. The State Legislature appropriated over $850,000 for various phases of investigation and control. Between 500,000 and 600,- 000 moth specimens that were caught in the oriental fruit moth JANUARY, 1944] KEIFER— APPLIED TAXONOMY 3 traps were identified in order to segregate the actual oriental fruit moths and learn the range of that species in California. While the moth was discovered here too late to allow eradica- tion, taxonomy has opened the way for control procedures and investigations before the pest has overrun commercal fruit orchards. With the principal activity of applied taxonomy in mind, namely the dispensing of specific determinations, it follows that the next most important thing is that of seeking new and better methods for differentating species, and for the recording of new species — a large task. Increased knowledge on species differen- tiation has in recent years had a profound effect on the control of screw-worm flies, red, yellow, and related scales, tomato pin- worm, and others. As little planning was done looking toward such results, we can only wonder how many more such things remain to be discovered by the chance of personal initiative. The application of taxonomy to economic entomology has been, and is being, practiced in a very limited fashion. Not many tax-supported entomological organizations give it a definite place in their set-ups. It enters into the planning of almost no eco- nomic projects. Commercial insecticide organizations freely consult governmental taxonomists but assume no responsibility themselves for the development of knowledge on insect identifi- cation. Applied taxonomy is not taught anywhere as such. Aside from what research the man on the job can do himself, the most he usually obtains from outside sources is an occasional chance article which is partly useful. The main reason our systematic data so often fails the applied taxonomist is that he must examine material and use techniques not popular with the usual taxonomist. This material consists mainly of species in the order Homoptera and of holometabolous larvae. While the source material in the Homoptera is in most respects fragmentary or preliminary from the applied viewpoint, one family of scale insects, the Diaspididae, has recently been well clarified. Let me point out that scales have perhaps more economic species than any other group of comparable size, and that the worker who has thus helped us is not employed by an economic organization. It is in the research on and knowledge of immature forms that we find the most discrepancies in data available to the ap- plied taxonomist. We have some valuable leads toward identi- 4 THE PAN-PACIFIC ENTOMOLOGIST [vOL. XX, NO. 1 fying holometabolous larvae but most of them are barely intro- ductory. Keys for identification of caterpillars by Fracker, for coleoptera larvae by Boving and Carigbead, and for part of tbe more primitive maggots by Mallocb, are among tbe best ex- amples of comprebensive literature on holometabolous larvae. In many particulars tbe identification features of important immature stages are at best in tbe minds of but a few people. Tbe medical side of applied taxonomy is probably in tbe best position, with considerable tborougbly-developed literature, es- pecally on mosquitoes and tbeir larvae. In contrast to tbis, in spite of all tbe years that tbe cotton boll weevil and relatives bave been serious pests, we still bave no careful analysis of tbe larvae of species in tbe antbonomine group. We know very little about immature Homoptera and Hemiptera. Immature stages, especally bolometabolous larvae, are usually tbe ones found doing tbe damage, and tbeir identification is the key to the situa- tion, as pointed out in connection with the oriental fruit moth. This is vital to economic entomology, but there is no clearly- defined effort to do anything about it. Research on new and better methods of species differentiation includes other activities as well as critical laboratory analytical methods. The collection and study of arthropods in the field by the taxonomist not only enables him to get adequate material, but gives him invaluable perspective on his work. This is true in re- gard to quarantined insects that do not occur in the area in which the applied taxonomist works, but the identification of which gives a meaning to legislative control. And, in order for the taxonomist to correlate the visble structures he studies with the habits or activity of the species, and to disclose the true nature of poly- morphism, applied taxonomic studies should be conducted in connection with greenhouses and rearing rooms. If we stopped our consideration of applied taxonomy right here, this branch of classification would be abundantly worth- while. But there is more to it than that. The simplest way tax- onomy aids insect control beyond species identification is by enabling the economic entomologist to borrow methods from the control of species similar to the one under suppression. An example would be the use of established scale control methods on new scale pests. Thus, taxonomy serves as an orderly basis for thinking, and correlates control methods. The spectacle of an economic entomologist fastening his attention entirely on one JANUARY, 1944] KEIFER— APPLIED TAXONOMY 5 \ species gives the impression that he will sooner or later be operating with a poverty of new entomological ideas. The cod- ling moth control fraternity is perhaps the best example in this case. Another way taxonomy can go farther than species naming is that of defining genera whenever possible, so that they not only have a structural significance, but also a bionomical or geo- graphical aspect. Geographical considerations are of prime im- portance in parasite explorations. In this connection, biological control organizations seem to have neglected what we might term the “geo-taxonomy” of the insect groups that contain species they seek to control. Taxonomy is primarily based on the comparison of arthro- pod structures. These structures are present because of some mechanical value to the individual arthropod. Structures are visible mechanisms, and the taxonomist, by comparing them, makes logical arrangements of these visible mechanisms. Impor- tant control methods are based on such things as oral mechan- isms, skin structures, and gland secretions. These have definite places in taxonomy, which has a wealth of comparative data on such structures. It is of profound significance that serological studies indicate that the chemical similarities of arthropods closely follow their mechanical aflEnities. Since taxonomy proceeds largely by the process of thorough comparison, therefore comparison is at the basis of taxonomic reasoning. With this fact in mind, let us momentarily analyze present practices in arthropod-control research. We immediately see a strong tendency to treat arthropod pest species as unrelated entities. For example, there are many articles in existence de- scribing the reactions of one species of insect to numerous control chemicals. That is perfectly correct as far as it goes, but taxo- nomic reasoning indicates that if the reverse aspect of this is not also investigated the whole thing is lop-sided. In other words, the reactions of numerous arthropod species to single chemicals will give interspecific variations in reaction, and these variations can then be correlated with visible mechanisms and biochem- istry. This does not imply that such a thing ought to be done in connection with each control project, but as a standard practice to give valuable data to control projects. The significance of the reciprocal toxicity of sulfur and cyanide to arthropods lack- ing or possessing spiracles would be a good subject for an in- 6 THE PAN-PACIFIC ENTOMOLOGIST [vOL. XX, NO. 1 vestigation of this type. The chemical side of the problem is the “what” side; the arthropod side the “why” side. I am not re- ferring in this case to attempts by insecticide companies to sell their products as cure-alls. Remarks have already been made leading up to the statement that applied taxonomy needs some special literature. There is no better origin for such literature than with the applied taxo- nomists themselves who owe it to their profession to publish the identification problems they solve. The type of literature needed is not that which is illustrated by a photograph or general sketch, but by figures drawn on the basis of interspecific and inter- generic comparison, analyzing the body comprehensively. There is enough information in existence scattered through books and periodicals, preserved in collections, and in the minds of a few people, to form a valuable manual or manuals, on preparatory methods and characters for the identification of economic arthro- pods and near relatives. With this as a basis we could build further knowledge in a really effective form. Let me conclude by repeating that the application of arthropod taxonomy to economic operations means restriction to study of pertinent arthropod groups. This taxonomy, as well as being restricted, has certain definite procedures and objectives, the most important objective being species identification. Applied tax- onomy depends for its future development squarely on the intel- ligent support of the organizations that need it. While the eco- nomic value of taxonomy is conceded, there is a general passive policy, both expressed and implied, that the solution of pertinent taxonomic problems must be largely based on the chance co- incidence of opportunity and ability or inclination. Amateur taxonomists have done important work, but economic entomology is a large and growing profession, and the amateur or passive slant on applied taxonomic development cannot assure such progress as is needed. Economic entomological organizations will find that the only effective applied taxonomy is that for which they are willing to be actively responsible.

REES University of Utah, Salt Lake City In October, 1934, and April, 1942, the available mosquito records for Utah were published by the author in this Jour- nah. 2 . The following constitutes a new genus and species record for the state. Mansonia PERTURBANS (Walker) Utah: Ogden, Weber County, July 8, 9, 10, 16, August 11, 27, 1943 (Rees). Adults of this mosquito, both males and females, were taken on the above dates on the Weber River directly south of Ogden in what is known as Riverdale. No larvae were collected, but conditions in the vicinity were suitable for their development. Adults were collected at this locality in a light-trap, by hand while feeding, and in rabbit hutches and other out-buildings. The adults were fairly abundant but were more numerous in this locality during July than in August. The author was unsuccessful in finding this species in other parts of Ogden or at several other localities along the Weber River that were inspected for this purpose; but undoubtedly this genus will be found to occur in other parts of the state as this work is extended. ^ Rees, Don M. 1934.

Head finely, closely punctate posteriorly, virtually impunctate in the testaceous portion before the eyes; a median impressed line on the occiput. Eyes moderately small; about one-fourth the length of the head in the female, a little less than one-third the length of the head in the male. Mandibles dentate; armed with a single strong, rather blunt tooth on the inner margin of the apical third of each mandible. Antennae slender, subcylindrical, those of the female relatively shorter and stouter than those of the male; second joint about two-fifths the length of the third in the male, about one- half the length of the third in the female. Clypeus pyramidal, apex acutely emarginate. Thorax subquadrate; anterior margin evenly arcuate or with a very slight sinuation at apex (some females) ; anterior angles not prominent, obtuse; posterior angles subacute but blunt; disk nearly impunctate, with only a few fine scattered hairs, these more abundant anteriorly; side margins bordered by a definite, heavier marginal pubescence, blunt, especially ante- riorly where the marginal pubescence is most abundant; rufo- testaceous, a little darker on disk than at sides; thorax of female relatively shorter than that of male and broadest anteriorly, mar- ginal pubescence less evident. Elytra rugose, with a soft, cinere- ous, primary pubescence, and stiffer, longer, black secondary pubescence. Tarsi moderately stout; anterior tarsi of male short and expanded. Anterior claw of protarsi of male cleft at tip, toothed at base, anterior meso-and metatarsal claws of male cleft at tip and with a blunt basal projection; anterior claws of all tarsi of female cleft at tip, toothed at base.

McClay; two specimens, Sequoia National Park, June, 1937, collected by F. T. Scott. This species has long been confused with Cantharis lautus Lee. because of the fact that LeConte’s type series of C. lautus is a species complex. Lautus was described in 1851, from a unique female with yellow legs. Later, LeConte associated a black-legged male with the type of lautus and subsequent references to C. lautus were rather to this male. Thus, for many years, C. dentatus has been determined as lautus, which is apparently a much rarer insect. Mr. C. A. Frost very kindly compared the types of C. dentatus with LeConte’s type series of lautus and concluded that it is “the same as the male associated with the type lautus” {in litt.) . The Male genital armature of C. dentatus Fender. 1, dorsal; 2, lateral, and 3, ventral view. female type of lautus does not have the last abdominal sternite modified as in this species. Lautus belongs with the notatus, perpallens, ingenuus, and ochropus group, whereas dentatus belongs with divisus, which also has the mandibles dentate. From divisus it may be easily distinguished by the immaculate thorax, and cinereous vestiture (golden in divisus), and from all other species by the ungual formation. The blunt basal projection of the anterior claws of the meso- and metatarsi of the males may, in some lights, almost appear to be a definite tooth (as is found in divisus), but in no case does it appear to be as acute as the basal tooth of the other ungues. I have seen a few females of divisus having the thorax imniaculate, but from these, dentatus females may be distin- guished by the peculiar formation of the last visible abdominal 22 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

Green for the loan of the specimen from Kernville, California, and for his having called the author’s attention to the fact that this species has the mandibles dentate, as in divisus.

The type material is distributed as follows: holotype, allotype and Glenada paratype in author’s collection. Two paratypes in Fender’s collection. The Seattle paratype in Dr. Hatch’s collec- tion. This species runs in Horn’s key to intrusus from which it differs having only 8-10 antennal joints transverse, 3 discal rows of punctures instead of one, coarser puctulation on the dorsal side of the abdomen and different coloration of the last two segments. It is also considerably larger than Horn’s species. This species is named after Mr. Jean H. Kremer of New York City, with whom the writer has spent many days in the field. Boletobius ruber Malkin, new species Reddish, shining, legs testaceous. Head: black, moderately elongate, highly polished, widest at base. Maxillary palpi testa- ceous; fourth joint short, conical, shorter than third; the first three sparsely pubescent. Antennae, as long as thorax and head. Basal joints testaceous, 5-11 piceous.

In Horn’s key it should be placed between dimidiatus and intrusus. Boletobius kelleyi Malkin, new species Color in general reddish -testaceous. Head black, twice as long as wide, highly polished with sparse, minute punctures. Maxillary palpi yellow, strongly prolonged. Fourth joint as long as the third.

M. & D. M. Fender, collectors. Type and 2 paratypes in author’s collection, 1 paratype in the collection of the California Academy of Sciences, 1 paratype in Fenders collection. This species is very closely related to B. anticus Horn and it has probedily been mistaken for that species in collections. It can be separated from the latter by having the thoracic spots posteriorly located instead of anteriorly, much broader yellow area on the fifth abdominal segment, and a very coarse punctu- lation on the ventral side of the abdominal segments. The specimens on hand exhibit very little variation except for the extent of the elytral spot and the number of punctures in the lateral row. The dorsal row is quite uniform as well as the ex- tent of the thoracic spots. Boletobius cascadensis hatchi Malkin, new subspecies Head oblong oval, black, shining. Maxillary palpi yellow all joints of nearly equal length. First two delicately pubescent. Thorax slightly wider than long; red, with disc indefinitely JANUARY, 1944] MALKIN— STAPHYLINIDAE 29 clouded, polished, very delicately, transversely alutaceous. Elytra as long as wide, polished. The black spot variable in size some- what posteriorly located, not attaining the suture. Dorsal series irregular, usually of 9 punctures, sutural of 10, lateral 8-10, irreg- ular but distinct. Abdomen piceous, segments broadly yellow in the apical, posterior portion. Yellow area of fifth segment occu- pying the entire apical half. Punctures sparse but distinct with the golden pubescence. Surface transversely alutaceous. Lateral spinules short. Ventral side: femora, tarsi, tibia red-testaceous. Epipleura black, except in the apical portion where they are reddish-testaceous. Mesosternum and metasternum as in kelleyi. Color the same as on the dorsal side. Segments very coarsely punc- tured, thickly pubescent. The punctures on the last two segments feebler toward the apex. Length, 3.5 mm.; width, 1.25-1.6 mm. Type and 26 paratypes of undetermined sex collected by M. H. Hatch on Mr. Bonaparte, Washington, July 12, 1931. Type and 17 paratypes in Hatch collection. Four paratypes in author’s collection. One paratype each in the collections of : California Academy of Sciences, Oregon State College, K. M. & D. M. Fender, C. A. Frost, and H. B. Leech. The series studied vary greatly in size and in coloration, par- ticularly in the extent of the elytral spot and in coloration of thorax. In some specimens the latter is almost piceous on the disc, but the margins are usually more pale in all specimens. This form differs from cascadensis by having the epipleura black in the posterior half, more conspicuous pubescence on maxillary palpi, absence of a definite pattern on thorax and con- siderably smaller in size and more robust body. B. cascadensis subsp. hatchi is undoubtedly, like the original form, mistaken in the collections for B. anticus. In Horn’s key it should be placed between cascadensis and pygmeus Fab. At present time the writer considers hatchi as a subspecies but it is quite possible that in the future it will be separated as a distinct species. Boletobius intrusus wallisi Malkin, new variety This form resembles the original form very closely except for the following differences: Smaller size, abdomen of much paler color and more coarsely punctured surface of the abdominal segments. Length, 5 mm.; width, 1.5 mm. Holotype, male and allotype, female. No. 5268, WINNIPEG, Manitoba, 27. VI. 1915, in the Canadian National Collection, both collected by Mr. J. B. Wallis. 30 THE PAN-PACIFIC ENTOMOLOGIST [vOL. XX, NO. 1 COPROPORUS VENTRICULUS (Say) In Dr. Hatch’s collection of Tachyporini a specimen of Copro- porus ventriculus (Say) has been found taken at Pierce, Idaho, on July 27, 1939. This is apparenty a new record for the state. Blackwelder in his revision of the genus* lists Oregon, Nevada, Washington and California and several Eastern and middle- western states as habitat of the species, but does not mention any Idaho records. There are also in the same collection 16 old specimens labeled “Seattle, fungus” which confirms its presence in that state. In spite of the literature records, this only represen- tative of the genus seems to be not common in the Northwest. The present writer has never been able to find any in Oregon, nor was he able to discover any in the Oregon collections as well as in other collections from the Northwest which he examined. Acknowledgments: In addition to writer’s own collection the following individuals contributed material for study through loan: Mr. H. B. Leech, Mr. J. B. Wallis, Dr. Melville H. Hatch, Professor James N. Macnab, Mr. and Mrs. Kenneth Fender, and Mr. L. G. Centner. Thanks are also due to Mr. R. L. Post, cura- tor of the entomological collection at Oregon State College, for the loan of certain material in his custody and to Mr. J. L. Shuh for the loan of the Boletohius material from his collection. The writer is also indebted to Dr. W. J. Gertsch of the American Museum of Natural History, to Dr. D. C.

JANUARY, 1944] POTTS— ACRAEINAE 31 SYSTEMATIC NOTES CONCERNING AMERICAN ACRAEINAE, II ( Lepidoptera : Nymphalidae) BY ROBERT W. L. POTTS University of California, Berkeley This article, with a previous one^ makes available the princi- pal changes and additions to the genus Altinote resulting from preliminary studies for a proposed revision of the American Acraeinae. I should like at this time to express my grateful appreciation to E. Gorton Linsley; to Wm. T. M. Forbes for the loan of ma- terial from the Cornell University collection; to Lawrence S. Dillon for the loan of material from the collection of the Read- ing Public Museum; and to Charles D. Michener for the loan of material from the collection of the American Museum of Natural History. Altinote (Abananote) carmentis Potts, new species Male. Dull black with faint whitish gloss. Forewing above marked only by red-orange streak in subcostal cell similar to that in erinoTYie, and by a series of five light buff spots beyond cell be- tween veins, traces of buff near anal angle and above radius; first three spots nearly equal-sized, ovate; fourth much larger, sub- triangular with long point toward outer margin; fifth smaller, elliptical. Hindwing unmarked. Underneath buffy-grey with first four buffy spots coalesced in a band, fifth spot slightly separated; orange subcostal streak re- peated; apex with faint, even intervenal stripes. Hindwing evenly striped, slightly darker at outer margin. Forewing (base to apex) 23 mm., total expanse 43 mm. Holotype male from Moyobamba region, Peru, December 15, 1925, from the Bassler collection in the American Museum of Natural History. Very similar in appearance to the female of euryleuca, but the band of spots entirely beyond the discal cell by about one- half the length of the first of the buff spots. Shape and size, as well as the red-orange stripe, are suggestive of erinome. ^ Potts, Robert W. L., Systematic Notes Concerning American Acraeinae, Pan- Pac. Ent., 19(1) :31-32, January, 1943. 32 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX, NO, 1 Altinote (Altinote) alcione mengeli Potts, new subspecies Male. Brown-black, more to black; similar to sodalis except forewing with basal area extended outwardly, orange, the orange apical band very narrow and not above radials, of three or four obsolescent spots; dark discal band widened, directed toward point slightly above anal angle. Similar underneath; hindwing with color striping much re- duced, yellow-orange at base ; greyish band barely apparent on disc ; striping between dark venal-intervenal stripes mainly brownish. Forewing 26.0 mm., expanse 49 mm. Holotype male from Jepelacis, Peru, without further data, in the Mengel collection of the Reading Public Museum. One paratype from Jepelacis and another from RiO HuALLAGA, AcHl- NAMIZA, Peru, also in the Reading collection. Two paratypes in the author’s collection, one from Jepelacis and one from Inca Pechetea, Peru. Similar to sodalis, but distinguished from it by the obsolete apical band, the heavier discal band, and the greater extent of the basal area. Variation of forewing in the paratype series is from 22.5 mm. to 26.0 mm. Altinote (Altinote) alcione bassleri Potts, new subspecies Male. Dark brownish. Forewing above with basal area pale orange, almost without reddish tone, extended to include lower angle of cell and spot in cell M 3 , with less than normal basal in- fuscation; apical band scarcely indicated; discal band not black, but dark brownish, only barely perceptible. Hindwing without marking. Forewing beneath similar to upperside, weakly striped in costal area, hence this more a dark stripe than normal, color striping in apex nearly absent; apical band very narrow, entirely between Rs and M2 or M3. Hindwing beneath very weakly striped, orange virtually absent, greyish band barely, if at all, apparent. Forewing 22.5 mm., expanse 42 mm. Holotype male and three paratypes from Moyobamba REGION, Peru, with no additional data; holotype and one paratype in the Bassler collection of the American Museum of Natural His- tory, the other two paratypes in the collection of the author. Similar in appearance to mengeli, but conspicously smaller, paler, and with somewhat more striped appearance beneath. Size variation of forewing from 20.5 to 22.5 mm. in the short series available for study. JANUARY, 1944] POTTS— ACRAEINAE 33 Altinote (Altinote) alcione moneta Potts, new subspecies Male. Dark brownish-black; forewing above closely similar to mengeli, but basal area red-orange, not so extended and scal- loped at veins at outer margin; apical band absent; discal band directed to well above anal angle. Beneath similar; discal band almost parallel to inner border in first half thence sharply angled toward anal angle, barely exceed- ing Cu 2 , not extending into normal dark outer border ; apical band very narrow, yellowish at outer edge; apex weakly striped, ground tone blackish. Hindwing more regularly striped than other alcione forms, yellow at base not strong, orange tinted, nebulous dark area at end of cell barely apparent, greyish discal band weak, tinted orange; dark outer border not strong; ground tone strongly blackish. Forewing 26.0 mm., expanse 45 mm. Holotype male, in the collection of the American Museum of Natural History, from 2-4° S, 78° W., Ecuador. Paratype with similar data in the author’s collection. Altinote (Altinote) alcione hermosa Potts, new subspecies Male. Brown-black, closely similar to sodalis, with normal basal area, medium discal band, comparatively extensive apical band, but color of basal and apical bands rose-orange. Forewing 24.0 mm., expanse 45.0 mm. Holotype male from Hermosa, 1600 M., Peru, May 6, 1935, in the author’s collection. Easily distinguished from all but the following subspecies and incarum by the rose color; distinguishable from incarum by the presence of the apical band, and from the next subspecies by the opacity of the colored areas. Altinote (Altinote) alcione leucothoe Potts, new subspecies Male. Similar to hermosa, except apical band longer, discal band somewhat more curved, directed more toward anal angle; basal area and apical band rose-orange, more rose than hermosa, and basal area in particular semi-transparent. Forewing 24.0 mm., expanse 45.0 mm. Holotype male and seven paratypes from region of Iquitos, Peru, according to data received. 1 should not be surprised, however, if the locality were farther to the west. Paratype variation exhibits a widening of the dark discal band, some variation in transparency from a specimen in which the pin label may be read through the basal area to translucence. 34 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX, NO. 1 The specimens are not rubbed, but fresh and in excellent condi- tion. Easily distinguished from hermosa by this transparency. In my opinion this series of alcione subspecies are more nearly genetic varieties, but without a considerably greater amount of material to study it seems better to conform to the usual prac- tice and give names to the recognizable forms. It is my belief that it will be found that virtually every range and valley from Colombia to Bolivia will exhibit a slightly different alcione form readily distinguishable by the student from series collec- tions, but difficult to describe or key out. Altinote (Altinote) ozomene alicunde Potts, new subspecies Male. Black with green irridescence over entire ground surface; larger than typical ozomene, otherwise similar. Forewing 28.0 mm., expanse 54.0 mm. Holotype male and two paratypes in the author’s collection, from Colombia, probably taken in February or early March, locality unknown, but believed to be near Queremal or Buena- ventura, altitude about 3000 to 4000 meters. The principal differences between this and the typical are in the definitely greenish irridescence, whereas the typical usually runs to purplish blue, never more than slightly greenish blue, and in the considerably larger average size, one paratype being slightly smaller, the other slightly larger than the type. Altinote (Altinote) stratonice albunea Potts, new subspecies Male. Similar to aereta, but with dark discal spots heavier above and forming an entire band both above and beneath; basal colored area almost eliminated by dark suffusion from base. Basal area beneath without suffusion. Disco-apical band light orange above, huffy underneath. Forewing 24.0 mm., expanse 44.0 mm. Female. Similar but larger, grey-black, with colored area prox- imal to transverse dark band clearly indicated, distally buffy- yellow. Beneath, forewing proximal area buffy brown-orange, distally buffy-yellow; costal area uniformly striped. Forewing 28.5 mm., expanse 54.0 mm. Holotype male and allotype female from RiO JONDACHI, near Archidona, 800 M., Ecuador, collected by F. Martin and Hazel Brown in November, 1939. In the author’s collection. This is the most extremely marked of all the stratonice sub- species known to me. PACIFIC COAST ENT. SOCIETY 35 PACIFIC COAST ENTOMOLOGICAL SOCIETY M. A. Stewart V ice^President H. H. Keifer President E. G. Linsley Secretary Proceedings One Hundred and Seventh-seventh Meetim The one hundredth and seventy-seventh meeting of the Pacific Coast Entomological Society was held at 2:30 p.m. on February 27, 1943, in the entomological laboratories of the California Acad- emy of Sciences, San Francisco. President Keifer in the chair. The following members were present: H. H. Keifer, E. G. Linsley, R. C. Miller, A. E. Michelbacher, C. D. Duncan, M. A. Stewart, E. 0. Essig, T. F. Kelley, R. W. L. Potts, R. F. Smith, and W. Y. Chong. Visitors were present as follows: F. M. Prince, G. L. Smith, 0. G. Bacon, L. L. McRae, S. Vrana, F. M. Frost, R. King, T. Algard, J. Guttseburg, C. Madsen, H. Madsen, P. H. Arnand, W. K. Brainerd, M. Gutterman, B. Prendergast. The minutes of the previous meeting were read and approved. The secretary reported recent action of the Executive Board in amending Article VI, Sec. 4, of the By-laws to permit the sale of 20 life memberships in 1943 on a budget payment plan extend- ing over not more than five years and including payments of not less than $10.00 per annum. Professor Essig reported that the Publication Committee had appointed Dr. Linsley as editor of the Pan-Pacific Entomologist to fill the vacancy left by Dr. Usinger, now in the armed forces. The membership committee proposed the following names: Carl J. Drake, F. M. Prince, and Harold Madsen. They were duly elected to membership. Dr. Duncan exhibited photographs of the larviform females of a phengodid beetle, as well as a slant-faced locust and lined June beetle (Polyphylla) . He also announced the completion of a key to the butterflies and skippers of Santa Cruz County. Dr. Linsley discussed retarded development and delayed emer- gence of Buprestis aurulenta Linn, in structural timbers. He sum- marized 12 cases ranging from 9 to 26 years, O’bserved in Califor- nia over a five-year period. He pointed out that the location of the infestations in the buildings, geographical areas involved, and general habits of the species all argued that the infestations orig- inated in the lumber yard (or possibly the forest) and existed prior to construction. The president then presented Dr. Linsley, who read a paper entitled “Natural habitats, sources, and reservoirs of insects asso- ciated with stored food products.” Dr. Linsley stated that these 36 THE PAN-PACIFIC ENTOMOLOGIST [yOL. XX, NO. 1 insects shared a number of characteristics which combined to make them pests. (1) They have a wide and more or less cosmopolitan distribution. (2) Most of the species reproduce more or less con- tinuously when conditions are favorable, a fact which renders them independent of seasonal and daily cycles. (3) Their small size makes them easy to overlook, making" it possible to transport them unnoticed from place to place and to fail to discover their presence until a population reaches injurious numbers. (4) Some species are able to survive relatively long periods without food enabling them to endure unfavorable food conditions as well as increasing their ability to survive transportation. (5) Most stored food prod- ucts insects have a wide range of food habits and many include the majority of dry food and drug products of plant and animal origin in their diet. This food range is greater than that generally attributed to most other insects. (6) Many of the species appear to have a wide range of tolerance for physical factors in the en- vironment, especially humidity. Because in any given environment the extremes may be more significant than the means, it is likely that these insects can tolerate more extreme conditions of tempera- ture and humidity than many less widely distributed forms. This is particularly evident with regard to the moisture content of food materials and most of the important species can survive in food- stuffs with a moisture content far below the optimum. (7) Finally, although these insects have a broad tolerance for extremes of humidity (and frequently temperature), man maintains suitable (probably optimum) conditions for most of the species in many buildings, warehouses, and food storage units. Dr. Linsley then discussed the original habitats and natural reservoirs of several hundred species associated with stored food products, from which the following conclusions were drawn: (1) Stored food products insects are widely distributed in nature as well as in the warehouses, granaries, and households of mankind. (2) Several of the species involved (bruchids, Sitophi- lus, Sitotroga, etc.) are seed infesting species which infest these same materials in nature. These insects have become pests with- out having to undergo further evolution of food habits. (3) A large number of insects (cryptophagids, mycetophagids, lathri- diids, acarids, etc.) associated with stored food products are actu- ally fungus feeders and their presence is due to molds and fungi existing in the foodstuffs. In nature these species are found under bark, in nests of birds, mammals and insects, in decomposing plant materials, any place where molds and fungi are present. (4) Many food products pests are general scavengers on dead plant mate- rials. The majority of these are moths (phycitids, pyralids, etc.) but a few other groups (Anobiids, nitidulids, etc.) are involved. (5) A similar source is found in the scavengers on dead animal materials. Included are Dermestes, Piophila, Tineola, etc. (6) A very important natural source of stored products pests is among the scavengers or semi-predators living under bark. To this source JANUARY, 1944] PACIFIC COAST ENT. SOCIETY 37 we must credit almost all of the tenebrionids (flour beetles, meal- worms, etc.), cucujids, ostomatids, etc., and to a wood boring origin, the ptinids, anobiids, bostrichids, and scolytids. (7) Insect nests have also offered a number of pests. Several of the gal- leriids, phycitids, ptinids, and dermestids, in particular, may have come from this source. The pollen stored by bees may have had an important role in the evolution of the food habits of some of the species by serving as a bridge between zoophagy and phyto- phagy. (8) Many of the insects in stored food products are preda- tors and parasites of other insects present. A few of these, espe- cially histerids, clerids, anthocorids, etc., are probably attracted to the products and habitat directly rather than by any specific in- sects present. (9) Primary natural reservoirs are to be found in the following habitats: (a) bark and decomposing wood, (6) nests and food caches of other insects, especially bees, wasps, and ants, and (c) nests of birds and mammals. After a discussion of this paper, the meeting adjourned. — E. G. Linsley, Secretary. One Hundred and Seventy-eighth Meeting. The one hundred and seventy-eighth meeting of the Pacific Coast Entomological Society was held at 2:30 p.m. on May 27, 1943, in the entomological laboratories of the California Academy of Sciences, San Francisco. President Keifer in the chair. The fol- lowing members were present: H. H. Keifer, E. G. Linsley, E. C. Van Dyke, E. 0. Essig, M. A. Stewart, A. E. Michelbacher, R. W. L. Potts, G. L. Smith, R. F. Smith, F. M. Prince, R. C. Miller, P. Moorhead, and P. A. Harvey. The minutes of the previous meeting were read and accepted. President Keifer announced the appointment of Dr. M. A. Stew- art to the publication committee and Dr. A. E. Michelbacher to the program committee. Mr. R. F. Smith reported that the alfalfa butterfly, Colias eurytheme Bvd., and lygus bugs, Lygus spp., were abundant on alfalfa in the San Joaquin Valley, indicating the possibility of damaging populations in that area later in the season. President Keifer then presented Dr. Van Dyke, who addressed the Society upon “Entomological Type Localities on the Pacific Coast.” Dr. Van Dyke confined his discussion largely to those localities which have had their names changed or which have been obliterated from various causes. He suggested that a list of such places should be compiled and published in order that future workers might know where they were. Hetch Hetchy Valley was destroyed as a collecting grounds when it was turned into a reser- voir; so also was Crystal Springs in San Mateo County, a type locality for many of G. R. Crotch’s species. Other places, like some of the old frontier forts vanished when the government abandoned them. Many of those near the larger communities like Los Angeles and San Francisco were destroyed by advancing cities. 38 THE PAN-PACIFIC ENTOMOLOGIST [vOL. XX, NO. 1 The localities listed by the early Russians in Alaska and Cali- fornia are mainly easily placed since they are either existing com- munities like Unalaska, Sitka, and San Francisco, places like Fort Ross (Colony Ross) and Sutter’s Fort (New Helvetia) which have been preserved as historical monuments, or stable landmarks like Point Reyes and Mt. St. Helena. Many of the J. L. LeConte locali- ties of the eighteen fifties are cities like San Diego or San Jose, others like Isabella are small places which, however, still retain their names. The famous G. H. Horn localities of Civil War days are Fort Independence in Owens Valley, with the fort destroyed but the site preserved by the town of Independence which has grown up around it, and Fort Tejon, now an historical monument. A few of the other noted localities mentioned by Dr. Van Dyke were Clarks’ Corners, now the famous resort Wawona; Tallac, at the lower end of Lake Tahoe, now no longer a resort; Havilah, long past its zenith but still maintaining a post office; Sissons, now called Shasta City, and Soda Springs, now called Upper Soda Springs, in the upper Sacramento Valley. Smaller suburban col- lecting sites have suffered greatly. Redwood Canyon in Marin County has become Muir Woods, Laguinitas Canyon is a water district and closed to the public. The main San Francisco collec- ting ground of Henry Edwards and Behr is now the heart of Chinatown; Lone Mountain is occupied by the Catholic Women’s College; Mountain Lake is in the Presidio and closed to the public, and Lake Merced scarcely remains as a collecting ground. The famous Sylvania was Ricksecker’s ranch, near what is now Camp Meeker, and Camp Taylor on Paper Mill Creek in Marin County, is preserved as a picnic ground. Following a discussion of Dr. Van Dyke’s paper, the meeting adjourned. — E. G. Linsley, Secretary. One Hundred and Seventy-ninth Meeting. The one hundred and seventy-ninth meeting of the Pacific Coast Entomological Society was held at 2:15 p.m. on September 25, 1943, in the entomological laboratories of the California Academy of Sciences, San Francisco. President Keifer in the chair. The following members were present: H. H. Keifer, E. G. Linsley, C. D. Duncan, E. C. Van Dyke, M. A. Stewart, F. M. Prince, F. J. Driver, R. W. L. Potts, and R. C. Miller. Visitors were present as follows: Oscar G. Bacon, A. M. Adamson, Barbara Prendergast, and Joseph E. Ryus. The minutes of the previous meeting were read and approved. President Keifer announced the appointment of a nominating committee consisting of Mr. Potts, Dr. Van Dyke, and Prof. Essig (chairman), and asked that they report at the next meeting. Dr. Van Dyke and Dr. Miller reported recent visits from ento- mologists in the service who were on their way overseas. Their remarks were supplemented by various others who had had recent JANUARY, 1944] PACIFIC COAST ENT. SOCIETY 39 visits or communications from members in the service. The secre- tary requested that he be kept informed of the most recent ad- dresses, ranks and branches of the service of Society members. Mr, Prince reported the results of recent plague surveys by the U. S. Public Health Service in western United States. He reported the collection of infected fleas from Neotoma and Citellus in New Mexico, prairie dogs in eastern Colorado and parts of Montana. His remarks were followed by considerable discussion of the geog- raphy of plague. Dr. Duncan called attention to the interesting paper on Rosalia funehris Mots, by Prof. Essig in the last number of the Pan-Paciflc Entomologist. In view of the apparent rarity of this species, he suggested that it might be of interest to know that Rex and Norma Bartges had collected 20 or 30 specimens on California laurel {Umbellularia calif omica) . Dr. Van Dyke commented that Mr. Ricksecker had collected several hundred from a skid row made of laurel, but that he, in 50 years of collecting, had taken only three live specimens. Mrs. Prendergast spoke of her studies on the life history and habits of an as yet unidentified species of Megachile in San Fran- cisco. The bees line their cells with petals from the California poppy (Eschscholtzia calif omica) and appear to be rather com- monly parasitized by a species of Coelioxys. The president then presented Dr. A. M. Adamson, Professor of Entomology, Imperial College of Agriculture, Trinidad, who addressed the Society on “The Biology of Trinidad Termites.” Dr. Adamson briefly discussed the geographical features of the island Trinidad, situated off the coast of Venezuela near the mouth of the Orinoco River. He also remarked on the richness of its fauna and flora, pointing out that biologists wishing to spend a short visit in the tropics will find Trinidad an exceedingly favorable location, with tropical rain-forests, large swamps of fresh and brackish water, savannas and other varied types of collecting grounds within easy reach of the capital, Port-of-Spain. In the neighboring island of Tobago are superb barrier reefs of coral. There is probably no region as near to the United States where so great a variety of animals and plants can readily be seen within a small area. The termites of Trinidad number over 70 species in some 20 genera. Two features of their biology were selected by Dr. Adam- son for special consideration, their systems of defense and their feeding habits. The most remarkable and highly developed defense practiced by termites is probably that of the genus Nasutitermes, in which the head of the soldiers is drawn out like a spray nozzle for the ejection of poisonous liquids. These “mobile units of chemical war- fare” are very numerous, swift, and aggressive. In action they appear to be very effective against ants, the principle natural enemies of termites. 40 THE PAN-PACIFIC ENTOMOLOGIST [yOL. XX, NO. 1 Large amounts of soil were found by Dr. Adamson in the ali- mentary canal of a large number of trinidad termites, especially in numerous species of Anoplotermes which live almost exclusively in the ground. However, other genera were also involved. It ap- pears that these termites swallow soil after the manner of earth- worms, in order to digest organic matter which it contains. This habit is probably common among tropical termites, although the literature contains few references to it. It is conceivable that termites may profoundly affect the soil in areas where abundant. In at least some of the genera studied. Dr. Adamson found soil in the alimentary tract of soldiers, as well as workers, but not in nymphs or members of the reproductive caste. Further observa- tions along this line should shed some light on the diet of the vari- ous castes, a subject difficult to investigate by other methods and about which almost nothing is known. After a general discussion of Dr. Adamson’s paper, the meet- ing was adjourned. — E. G. Linsley, Secretary. One Hundred and Eightieth Meeting. The one hundred and eightieth meeting of the Pacific Coast Entomological Society was held at 2:30 p.m. on December 18, 1943, in the entomological laboratories of the California Academy of Sciences, San Francisco. President Keifer in the chair. The fol- lowing members were present: H. H. Keifer, E. G. Linsley, E. 0. Essig, A. E. Michelbacher, R. F. Smith, R. C. Miller, W. H. Lange, E. C. Van Dyke, M. A. Stewart, F. M. Prince, W. M. Pearce, P. Moorehead. One visitor was present, Mr. Joseph Ryus. The minutes of the previous meeting were read and approved. Prof. Essig reported for the nominating committee the follow- ing nominations for officers for 1944: president, M. A. Stewart; vice-president, F. P. Keen; secretary, E. G. Linsley, and treasurer, R. C. Miller. It was moved, seconded, and passed that the secre- tary cast a unanimous ballot for the candidates. Mr. Keifer then turned the gavel over to the new president. Dr. M. A. Stewart. Dr. Stewart paid tribute to the services of the retiring president and called attention to the increasing obligation of the Society to help maintain scientific values, support funda- mental work, and maintain continuity of effort during the present world crisis. He urged that all members make a special effort in attendance at meetings and in helping to make the meetings inter- esting and worthwhile. President Stewart then presented the retiring president, Mr. Keifer, who addressed the Society upon “Applied Entomological Taxonomy” (see p. 1). Following a general discussion of the sub- ject, Mr. Keifer reported upon his investigations of eriophyid mites, as an example of applied taxonomy. Considerable discussion followed Mr. Keifer’s paper, after which the meeting adjourned. — E. G. Linsley, Secretary.

The Pan-Pacific Entomologist Vol. XX, No. 2 April, 1944 A NEW GENUS — HEBENARUS — AND THIRTEEN NEW SPECIES OF LEAFHOPPERS CLOSELY RELATED TO CLOANTHANUS (Homoptera, Cicadellidae) BY DWIGHT M. DeLONG Department of Zoology and Entomology, Ohio State University In working over the species of leafhoppers collected in Mex- ico, which belong to the Platymetopius groups, some 50 species have been placed in the genus Cloanthanus, one in Scaphytopius, while others did not seem to belong to any of the described genera. A series of rather closely related species have, there- fore, been separated out and a new genus Hebenariis is being erected to include these thirteen species. Scaphytopius ritanus Ball is being placed in this genus and new species are described in the present treatment. Unless otherwise indicated all the holo- type, allotype and paratype specimens are located in the author’s collection. Hebenarus DeLong, new genus Related to Cloanthanus Ball but differing' from it by a flat vertex which is usually bluntly angled and as a rule is about as wide or slightly wider than long. The sides of vertex are usually rather convexly rounded to the blunt apex. The vertex is also characteristically marked by a pale margin bordered above and below by a black line. This marking on the vertex margin is more like Scaphoideus. The face is not angled above as in Cloanthanus and is usually banded just beneath the apex. The venation is simi- lar to that of Cloanthanus with numerous short costal veinlets. The species of this group are not marked with peppered or stip- pled pigment spots as is so frequently found in the color patterns of species of Cloanthanus. The types of genitalic structures of both male and female, although differing among the species of this genus, are distinct from those types found in the species of Cloanthanus. Genotype Hebenarus pallidus DeLong. 42 PAN-PACIFIC ENTOMOLOGIST [VOL.XX,NO. 2 Hebenarus pallidus DeLong, new species Resembling ritanus in general appearance but with shorter head, pale vertex and scutellum and with distinct male genitalia. Length 4.5-5 mm. Vertex short, bluntly angled, distinctly wider between eyes than median length. Color: Vertex and scutellum white tinged with yellow, margin of vertex pale bordered above and below with a brown line. Face with a narrow white band just beneath the lower black line, below this is a darker band between the eyes, and the remainder of the face is white. Pronotum white tinged with yellow, the disc appear- ing brown. Elytra subhyaline with dark brown veins. Genitalia: Female last ventral segment with posterior margin almost truncate, punctured either side of a broad, shallow, U- shaped notch on median third. A broad black stripe extends from this portion of margin to base of segment. Male plates short, triangular. Style with a long finger-like process arising on inner margin and extending outwardly. Aedeagus composed of an L- shaped dorsal portion the base of which is bifid and about as long as the stem. This is attached to the base of the ventral portion which is composed of a pair of proximal pieces which in ventral view are tapered from the base to slender pointed tips. In lateral view each piece has a prominent spine on the dorsal side formed at the base of the arrowhead tip. Holotype male and allotype female from Mexico City, D. F., Mexico, elevation 7,500 feet, collected September 1, 1939, by the author. Paratype male collected at same locality September 13, 1939, by the author.

Vertex bluntly angled, a little longer on middle than basal width between the eyes in female, about one-fourth longer than basal width in the male. APRIL, 1944] Delong— HEBENARUS 43 Color: Yellow tinged with orange, margin of vertex paler, bordered above and below with a slender brown line. Face dull orange brown a conspicuous pale arc just below margin. Elytra tinged with orange on basal portion with numerous pale spots and areas, posterior portion almost pale hyaline, veins orange. Genitalia: Female last ventral segment broadly, slightly pro- duced. Male plates short, triangular, apices blunt. Style with a long finger-like apical process arising on inner margin which curves outwardly. Aedeagus composed of a dorsal and a ventral portion. The dorsal portion in lateral view is L-shaped with the base of the “L” extending vertically in the basal portion of seg- ment. This is attached to the ventral portion by a narrow basal strip. Ventral portion composed of a single piece. When viewed laterally it is broad at base and tapers to a slender apex which bears a pair of long spine-like processes extending laterally. This species was originally described from specimens col- lected at Tucson, Santa Rita Mountains and Pima County, Ari- zona. A pair of specimens were collected in the Santa Rita Mountains and compared with the types by Dr. Oman and through his kindness have been available for study and dissec- tion. This species has not been collected in Mexico, but un- doubtedly occurs in some of the northern mountain ranges of that country.

LARVAL LONGEVITY IN BUPRESTIS AURULENTA LINN The writer has recently reviewed^ available information on larval longevity and delayed emergence of Buprestis aurulenta Linn, from structural timbers. Subsequently an interesting record from Guam was noted in an article by Swezey^. Swezey states, “One specimen of this American species was obtained in our residence at Piti, July 9, [1936]. It had apparently issued from a porch floor board as there was an exit hole which appeared fairly fresh. Two other similar holes had an older appearance. The boards were of Douglas fir which had been shipped from the Puget Sound Region. The house was constructed prior to 1915.” Although Swezey expresses the doubt that the larva could have existed for that length of time before maturing, I think there is now little question but that this was actually the case. — E.

WOLCOTT Downer’s Grove, Illinois A third of a century has elapsed since the writer prepared his synopsis of the Trichodes^. At that time ten species were known from our fauna, later two other species were described, the first of these being bicinctus Green, the other hasalis Van Dyke, thus bringing the number of known species to an even dozen. As it is likely that few, if any, remain to be discovered the present time appears to be opportune for the presentation of an amended and augmented table of species. It is very probable that eventually the name Trichodes Herbst, will have to be dropped in favor of Clerus Fab. John Curtis^ in 1824 designated Attelahus apiarius Linn., as the genotype of Clerus, in which move he was followed by a number of other writers. In 1840 F. W. Hope^ also designated T. apiarius Lirin., as type of Clerus Latr., and synonymized it with Trichodes Fab. Dr. E. A. Chapin (m litt) who has thoroughly investigated the status of these two generic names finds that they are isotypical and that Clerus Fab. (1775) has priority over Trichodes Herbst (1792). Thus in conformity with the rules of nomenclatural procedure it will be necessary to substitute Clerus Fab. for the name Trichodes of Herbst. The present writer retains the name Trichodes merely as a matter of convenience. Key to the American Species of Trichodes 1.

Linsley has very kindly supplied the writer with an excellent sketch of the elytral markings of the type specimen of this species, a copy of which is presented (Fig. 1). Dr. Linsley also sent some helpful and valuable notes pertaining to this species, which are quoted in their entirety “In form it resembles a slender specimen of oresterus Wolcott, the basic elytral pattern is also similar to some examples of oresterus. However, the pale areas of the elytra are clear yellow without any reddish or orange tint. The pronotal pubescence is yellow and a little longer (pos- sibly also denser) than in my series of oresterus. The punctures of the pronotum and elytra are coarse but less deep than those of oresterus. Likewise the legs and entire under surface is brownish-yellow in contrast to the blue color and red abdomen of oresterus.^’ (Linsley, in litt.) Type locality: Imperial County, California. Trichodes bicinctus Green Trichodes bicinctus Green, 1917, Ent. News., 28:367. Dr. J. W. Green very generously gave the writer one of the two males mentioned in his original description of this species. The specimen is from Green Valley, Brewster County, Texas, July 14, collected by J. W. Green. It agrees with the description in every detail. A figure of the elytral pattern is shown (Fig. 2). Dr. Linsley also presented the author with a pair of this spe- cies, male and female, taken on flowers at Laredo, Texas, June 12, 1932. In both of these specimens the body beneath is green, the abdomen greenish black. The black elytral markings reduced to two transverse maculations on each elytron and the apex with a narrow lunate maculation. This form is represented by the fig- ure given (Fig. 3). The elytral apex is rounded in both sexes. Trichodes horni Wolcott and Chapin Trichodes homi Wolcott and Chapin, 1918, Bull. Brooklyn Ent. Soc., 13:107. Trichodes illustris Horn, 1876, Trans. Amer.

In a specimen from Parma, Idaho, the basal three-fifths of the elytra red, the posterior margin of this portion truncate, the red portion has the humeral umbones and a very small oblique maculation at the middle blue, the apical two-fifths blue, with the usual oblique yellow fascia of this part. In another specimen from the same locality the elytra are entirely red, with a small postmedian marginal maculation and the apices narrowly blue. In a specimen from Aspen Lake, Klamath County, Oregon, the elytra are entirely blue, with a very small transverse yellow maculation distant from lateral margin, at middle of each elytron. To the localities in which T. ornatus and T. nutalli occur in common Pike’s Peak, Colorado, may be added. Trichodes omatus var. nov. obsoletus Wolcott Form rather robust, Elytra at base nearly one-half as broad as long, sides straight and parallel, scutellar area deeply and broadly depressed, base midway between the scutellar depression and the humeri depressed, thus causing the humeral umbones to appear very prominent, each elytron with a deep, rather broad groove parallel to the suture, extends from the scutellar depression nearly to the elytral apex. Head dark green, rather shining with slight aeneous lustre, coarsely roughly sculptured, antennal clava broad, short. The antennae, palpi, tibiae and tarsi fulvous, clothed with short, rather dense fulvous pile. Pronotum green, with distinct aeneous lustre, coarsely, rather sparsely, irregularly punctate. Elytra cyaneus with cupreous lustre, moderately shining, coarsely, densely punctate, sutural bead very dark blue, elytral markings arranged as in T. ornatus, but practically obsolete, faintly badius and this covered by a faintly sordid whitish surface gloss.

Trichodes apivorus var. borealis Wolcott and Chapin This name (which appears in the key) was proposed by the authors to replace the preoccupied name interruptus LeConte. HIBERNATION OF DASYMUTILLA AUREOLA PACIFICA On January 21, 1944, while collecting under rocks near Pat- terson Pass, Alameda County, Calfomia, elevation 1150 feet, two unworn female Dasjmutilla aureola pacifica (Cresson) were found in hibernation. Under the same rock was a broken 3-cell nest of Sceliphron servillei (Lepeletier) which apparently had not produced adult wasps. MickeP cites common records of aureola pacifica from March through November, while a single December and a single Janu- ary record are also given for Berkeley. Mickel also notes that a very great size variation is known in the female, indicating the probability of a variety of hosts. In his general summary of the life history of a Mutillid it appears that hibernation is normal for the prepupal stage. Bohart and MacSwain^ give the activity record for another species {D. sackenii (Cresson) as June to November and state that pupation occurs in spring or early sum- mer, after hibernation in a prepupal stage. It would appear possible that in this case Sceliphron had served as the host and that the life cycle was such as to produce fresh adult females in the late fall or winter months. Such a cycle is at variance with those reported by Mickel and by Bohart and MacSwain, although Mickel lists specimens taken in the winter months. It is possible that these also were hibernating. Determination of the mutillids was made by Mickel; of the wasp nest by E. Gorton Linsley. — R.W.L. Potts and R.F. Smith. ^ Mickel, C.

T. Padgen and R. A. Lever and sent to the writer by Sir Guy A. K. Marshall, Director of the Imperial Institute of Entomology, British Museum (Natural History). Seven species, including an unidentifiable one, are represented in this material. Of these two are known forms and four are described as new. The types of the new species are temporarily placed in the Field Museum of Natural History, Chicago, Illinois, while paratypes remain in the collection of Eugene Ray. Mordella lottini Boisduval (Fig. 1) Mordella lottini, Boisduval, 1835. Voy. Astrolabe 2 :291. One specimen: Tulagi, November 25, 1934 (H. T. Padgen).

Body densely covered 62 PAN-PACIFIC ENTOMOLOGIST [vOL. XX, NO. 2 with fine, recumbent pubescence, partaking of ground color, ex- cept for the following albo-pubescent areas: head completely, pro- notum wtih a thick line at base, broken at middle, scutellum com- pletely, elytra with a pre-median rounded spot on disc of each, which in some specimens tends to extend obliquely toward humeri, a postmedian discal spot which varies from a rounded condition to a thick oblique one, meso- and metasternum and legs completely but less densely than on head, and basal margins of abdominal segments. Antennae .9-1.1 mm. long, segment 2 shorter than 1, 2-3 equal in length, the former broader, 4-10 each two-thirds longer than 3, feebly serrate, 11 longer than 10 but narrower, sides and apex rounded. Terminal segment of maxillary palpi enlarged, with the form of a scalene triangle. Pronotum broader than long (.76-1.25 x .6-.95 mm.), anterior margin and sides rounded, broadest before base, arcuate, midbasal lobe short, broad, subtruncate. Scutellum large, broadly triangu- lar, sides and apex rounded. Elytra but twice as long as broad (1.6-2.43 x .76-1.25 mm.), broadest near base, sides curved from the broadest point to apex, apices individually rounded. Anterior and intermediate tibiae equal to their tarsi in length, penultimate segments of the latter expanded, distal margins straight. Anal style robust, abruptly narrowed before middle, thence attenuate to apex, between 2.3 and 2.6 times length of apical ventral segment (.8-1.27 x .35-.48 mm.). Posterior tarsal claws with three teeth, two equal in size, one before, the other after the middle, the third one terminal. Length: to apices of elytra, 2.2-3.38 mm.; to tip of anal style, 3-4.65 mm. Ten specimens: Type, male, TuLAGi Is., March 31, 1934, taken from low herbage on ridge (H. T. Padgen) ; a male para- type, type locality, November 25, 1934 (H. T. Padgen and R. A.

In Blair’s key to the Mordella of the Fiji Islands (Ann. Mag. Nat. Hist.

Body densely covered with fine, recumbent golden pubescence, somewhat coarser on the venter than elsewhere. Antennae 1.9 mm. long, slender, filiform, reaching beyond base of abdomen, segments 1-3 short, 2 and 3 each successively shorter than the preceding, 4 as long as 2 and 3 together, 4-10 elongate, each somewhat broader at apex than at base, 11 distinctly longer than 10, broadest before apex, sides strongly curved. Three distal segments of maxillary palpi enlarged and fiattened in both sexes, terminal segment subquadrate in male and smaller than the isosceles-triangular segment in female; second segment greatly enlarged and bell-shaped in male, of normal size in female; third segment large in both sexes, ovate in male, quadrangular in female.

Posterior tibiae with four equal, oblique, parallel ridges (excluding sub- apical one) ; basitarsi with four, second and third segments each with two ridges. Anal style slender, slightly curved ventrad, at- tennuate to apex, but twice length of apical ventral segment (1.4X.65 mm.). Posterior tarsal claws with six teeth, the basal one before middle, others successively larger distad. Length: to apices of elytra, 3.64 mm.; to tip of anal style, 5.04 mm. Nine specimens: Type, male, two male and two female para- types, Tulagi Is., October 29, 1934, on Hibiscus flower (R. A. Lever) ; one male paratype, Guadalcanal, March 4, 1935 (R. J.

This species is closely allied to the group that includes! the Fijian Mordellistenu dodoneae (Montoruzier) and M. consimilis Blair. It is similar in general appearance, but differs in its larger APRIL, 1944] RAY— MORDELLIDAE 65 size, the shorter second and third segments of the antennae and the additional oblique ridge of the posterior ba&itarsi. No men- tion is made of peculiarities of the maxillary palpi in the liter- erature pertaining to these allied species and it is thus assumed that the palpi are of normal form. The writer has received word that, of the species sent for study, none can be identified with forms described by Blair and others in the collection of the British Museum and it is therefore assumed that additional, un- deseribed differences exist. Mordellistena abrupta Ray, new speeies (Figs. 10, 11, 13) Form elongate-ovate, narrow, slightly but distinctly curved. Derm fusco-castaneous, legs, antennae and mouth parts castane- ous, ridges of posterior legs black. Body densely covered with fine, recumbent pubescence, partaking of ground color and distributed equally finely over entire surface. Antennae 1.6 mm. long, slender, filiform, reaching distal ab- dominal segment, segments 2-3 short, together equal in length to 4, 4-10 equal in length, but becoming successively narrower distad, 11 distinctly longer than 10, broadest beyond middle, sides strongly curved. Three distal segments of maxillary palpi enlarged, flat- tened, terminal and penultimate segments subquadrate, the former much the larger of the two, antepenultimate segment almost as large as terminal one, subtriangular. Pronotum distinctly broader than long (1.13x.94 mm.), ante- rior margin and sides rounded, broadest before base, base arcuate, midbasal lobe short, broad, subtruncate. Scutellum large, broad, base concave, sides slightly convex. Elytra narrow, more than three times as long as broad (2.2 x .7 mm.), broadest near base, curved from a postmedian point to apex, apices individually rounded. Anterior and interfiiediate tibiae longer than their tarsi, penultimate segment of the latter broadened at apex, its apical margin excised. Posterior tibiae with three, equal, oblique, parallel ridges (excluding subapical one) ; basitarsi with three, second and third segments each with two ridges. Anal style slender, slightly curved ventrad, attenuate to apex, almost three times length of apical ventral segment (.95 x .35 mm.) ; posterior tarsal claws with four teeth, the basal one postmedian, others successively large distad. Length, to apices of elytra, 3.14 mm.; to tip of anal style, 4.09 mm. One specimen: Type, male, Guadalcanal Lunga, March 4, 1935 (R. A. Lever). 66 PAN-PACIFIC ENTOMOLOGIST [vOL. XX, NO. 2 This species is most closely allied to maxillaris, new species, described above, but may be separated by its darker color, smaller size, and differences in the ridges of the posterior legs, the peculiar maxillary palpi, and in the tarsal claws with a smaller number of teeth. From consimilis Blair it may be sep- arated by its larger size, longer antennae and the shorter tibial ridges, in addition to the peculiar maxillary palpi. When the female of this species is found it seems probable that sexual differences in the shape of the maxillary palpi will be found to exist. Mordellistena oceanica Ray, new species (Figs. 4, 7, 8) Form elongate, sides subparallel, derm generally black, with the following exceptions: front and clypeus castaneous, sides of pronotum broadly rufo-castaneous, connected by a narrow, sub- apical, transverse band (only in male!); legs flavocastaneous; tibiae and femora of hind pair darker. Body densely covered with fine, recumbent pubescence, generally partaking of ground color, except on venter, where it is whitish, and on pronotum and elytra, where it is condensed to form whitish bands, as follows, on pro- notum, a thick, premedian line curved anteriorly to meet the an- terior angles and extending along sides to base, a line along base with three short vittae extending into disc; scutellum entirely; elytra with a curved band surrounding humeri, a short, subbasal, subsutural line curving inward to meet scutellar area; a median area formed like an M, but broken at suture; a small, circular area lateral to the previous one; a postmedian, inverted, M-shaped area, reaching lateral margins, but broken at suture; and a short, transverse, apical area. Antennae 1 mm. long, elongate, narrow, filiform, reaching meso- sternum; 4 one-third longer than 3; 5-10 each as long as 3 and 4 together; 11 distinctly longer than 10, sides curved, one distinctly convex, the other almost straight, broadest premedially. Terminal segment of maxillary palpi enlarged, with the form of an isosceles triangle, distal margin transverse, straight. Pronotum distinctly broader than long (.8-.65 mm.), anterior margin and sides rounded, base arcuate, midbasal lobe short, broad, rounded. Scutellum broad, rounded-triangular. Elytra two and two-third times as long as broad (2.35 x .8 mm.) , sides gently curved from base to postmedian point, thence strongly curved to apex, apices individually rounded.

This species belongs to the same group as the previous two species, but may easily be separated by the difference in the rela- tive lengths of the antennal segments, the striking pattern of pubescent markings on the pronotum and elytra and the smaller size. PREY OF THE ROBBER FLY CALLINICUS CALCANEUS LOEW (Diptera: Asilidae) BY E. GORTON LINSLEY University of California, Berkeley In May, 1942, near Oakhurst, Madera County, California, the writer had several opportunities to examine the insects captured by Callinicus calcaneus Loew. In this area the species was fly- ing about over a hillside covered with mountain mizery, Cha- maebatia foliolosa Benth., and was apparently preying almost entirely upon bees which were visiting the blossoms of this plant. Twenty-two specimens of the robber fly were captured with their prey. The prey consisted entirely of megachilid and andrenid bees as follows: Species Specimens Osmia brevis Cresson .... 9 Osmia cara Cockerell .... 5 Osmia densa pogonigera Cockerell . 1 Osmia lignaria Say .... 1 Andrena auricoma Smith ... 3 Andrena angustitarsata Viereck . . 1 Andrena carliniformis Cockerell . . 1 Andrena saccata Viereck ... 1 68 PAN-PACIFIC ENTOMOLOGIST [VOL. XX, NO. 2 Although the above sample is probably too small to be in- terpreted as significant of the food preference of Callinicus cal- caneus Loew, it is interesting to note that the genus O'smia repre- sented nearly three-fourths of the prey examined, Andrena only about one-fourth, although the seventeen species of Andrena present individually outnumbered the eight or nine species of Osnda by about five to one, as determined by analysis of 536 specimens captured by indiscriminate sweeping of the blossoms. It might be pointed out, however, that all of the Osmia captured are brilliant metallic green or blue, whereas the andrenids, with the exception of the golden Andrena awricoma, are dull, incon- spicuous species. It is well known (Banks, 1913; Bromley, 1914-36; and Mc- Atee & Banks, 1920) that many of our North American robber flies prey primarily upon aculeate Hymenoptera, although most of the records involve the honey bee and other social bees {Bombus) and wasps [Vespa, etc.). Among the species which do appear to prey to some extent on solitary bees may be men- tioned Saropogon dispar Coq. (Halictididae, Andrenidae), Diog- mites texanus Bromley (Halictidae) , D. Symmachus Loew (An- thoporidae, Andrenidae), D. angustipennis Loew (Halictidae), D. umbrina Loew (Andrenidae, Halictidae, Megachildae) , Proc- tacanthus philadelphicus Macq.

APRIL, 1944] BOHART— STENODYNERUS 69 STENODYNERUS FUNDATUS AND RELATED SPECIES IN NORTH AMERICA ( Hymenoptera, Vespidae) BY RICHARD M. BOHART University of California, Los Angeles The various species of the fundatus group of Stenodynerus are among the commonest solitary wasps. Their range covers most of North America as far south as northern Mexico. They are all moderate in size, fairly slender, and possess the two pits on the front face of the pronotum which are characteristic of the genus Stenodynerus. They are more particularly distinguished by having no acarinarium under the short first abdominal tergite, by having a fine abundant silvery pubescence on the sides of the thorax and by the fact that the third abdominal tergite has a complete apical band.

XX, NO. 2 A NEW SPECIES OF CICINDELA AND TWO NEW RECORDS OF COLEOPTERA BY BERNARD ROTGER San Luis, Colorado Cicindela theatina Rotger, new species Head and thorax shining' green tinged frequently with coppery lustre, anterior and basal impressions of thorax purplish. Elytra dark reddish cupreous, opaque; at times greenish toward the base, with basal reflection purplish or green. Legs and underside of body metallic green. Labrum short, white, and more than three times wider than long, with a small tooth. Head hairy between the eyes, with many interocular striae; palpi pale, with last joint green. Prothorax sparsely covered with long white hairs, sub- quadrate, scarcely wider than long and convex. Elytra granulate- punctate, punctures rather distant generally, and green, but more closely spaced toward base; interspaces reddish cupreous; elytral markings consist of humeral lunule almost reaching, and in sev- eral instances actually reaching middle band and merging into it, middle band obliquely bent with long extremity not hooked at tip, but sometimes dilated, and apical lunule; all markings widely united at margin. Palpi, four front trochanters, femora, sides of abdomen as well as of thorax very hairy. Elytra more parallel in male, wider and subparallel in female, apex being flnely serru- late. Tarsal claws long. Length, including labrum, 12-14.50 mm. Holotype male, allotype female, and topoparatypes in the Rotger collection. I believe that this species might be placed between Cicindela lengi and C. limhata Say. This species inhabits the edge of the Great Sand Dunes in the San Luis Valley, Colorado, at an altitudef of about 8,200 feet, where it was found by the author in three field trips, on the 26th of June, the 28th of August, 1942, and on the 19th of May, 1943. It was discovered on the side of Mosca Pass where the road ap- proaches the Sand Dunes, in spots of scanty vegetation and where the shfting sands begin. It was not found farther in the sand where there was no vegetation. The beetle runs rapidly upon the sand and it emits an orange liquid from its moiith. This tiger-beetle emerges in August, when the most perfect specimens can be obtained, and probably hibernates in the sand until spring. By the reason of frequent sand storms to which this species is subjected, the specimens caught in June lack most of APRIL, 1944 ] ROTGER— COLEOPTERA 77 the hair on the front and on the upper side of the thorax. During the month of August a few specimens were taken belonging to the preceding generation, and are of a dull green bronze. On July 5, 1937, Mr. R. P.

Two years after, on August o, 1 found four specimens of the same subspecies, at Farmington, New Mexico; the following year on July 13, at Canon Largo about eight miles from Blanco, New Mexico, I Fig. 1. Elytral pattern of Cicindela theatina Rotger. caught eleven specimens of the same. Mr. Mont A. Cazier who identified this form informed me that it had never before been taken in New Mexico. Looking after butterflies, I was forced by the cloudy day to pay more attention to Coleoptera, and luckily so, for I found among small ants a few specimens of Fustiger knausi Schfr. This is the first time that the Clavigeridae family has been col- lected in Colorado. The species was found as I was descending from Mesa Reservoir, near Durango, on April 30, 1941. Mr. Alan S. Nicolay made the identification. 78 PAN-PACIFIC ENTOMOLOGIST [vOL. XX, NO. 2 HOST PLANT RECORDS OF WESTERN LYGUS (Hemiptera, Miridae) BY ROBERT L. USINGER University of California, Davis The pratensis group of the genus Lygus is rich in both speci- mens and species in western North America. For several years I have kept careful host records in an attempt to define the limits of variation within species in this difficult group. The following records appear to be new: 1. Lygus distinguendus Reuter. Three specimens of this species were beaten from willow, Salix sp., Malahat Drive, Van- couver Id., B. C., June 26, 1940 (R. L. Usinger). The variety tahoensis Knight was taken on the same host on the trail to Glen Aulen, Yosemite National Park, California, July 27, 1939 (R. L. Usinger). 2. Lygus hradleyi Knight. A long series was collected on Yel- low lupine along the beach at Areata, California, July 8, 1940 (R. L. Usinger). 3. Lygus stratus Knight. Common on lupine at Miguel Mead- ows, Yosemite National Park, California, July 11, 1941 (R. L. Usinger) . 4. Lygus per plexus Stanger. Common on forest anemone. Ane- mone sp., near timberline (5500 ft.). Paradise, Mount Rain- ier, Washington, June 22, 1940 (R. L. Usinger). 5. Lygus convexicollis Reuter. This and the variety coloratus Knight were common on Madia at Miguel Meadows, Yosemite National Park, California, July 7, 1941 (R. L. Usinger). 6. Lygus usingeri Stanger. The type series was collected on cream bush, Holodiscus discolor, on the trail to Nevada Falls, August 14, 1938 (R. L. Usinger). No specimens have been found earlier in the season. This and the following species belong to the nubilus-nubilatus group. Nubilus Van Duzee, as noted by Van Duzee, occurs on elderberry, Sambucus. I have found it common on Sambucus in the Oakland Hills and in the San Jacinto Mountains. 7. Lygus nubilatus Knight? Specimens which I have tentatively placed here were collected sparingly on Spiraea douglasii in the Blue Mountains, Oregon, July 4, 1940 (R. L. Usinger) and along the Malahat Drive, Vancouver Id., B.

This species is rather common over much of California and Oregon. A NOTE ON THE HIBERNATION OF MISCHOCYTTARUS FLAVITARSUS IN A NEST OF DOLICHOVESPULA ARENARIA. On about February 1, 1944, a nest of Dolichovespula arenaria (Fab.) was brought into the Division of Entomology and Para- sitology, University of California at Berkeley. The nest contained no live D. arenaria. This was to be expected at that time of year since the colonies commonly die out from midsummer to early fall and the nests are deserted through the winter. Oddly enough, however, the comb contained a large amount of brood including many individuals which had transformed to the adult stage but had died before emerging. The cause of their death was un- certain. They did not appear to have died of any disease. They may have been killed by cold, or more likely, they were unable to emerge due to lack of nourishment in the late larval stages when the colony was declining. Another very interesting fea- ture of this nest was the fact that it contained nearly a hundred adults of Mischocyttarus flavitarsius (Sauss.). This unusual number of M. flavitarsus no doubt represented females bibem- ating in the abandoned nest. However, it is not uncommon to find small groups of the overwintering females collected in pro- tected places. — Ray F. Smith.

L. CRAWFORD’S SPECIES OF THYSANOPTERA BY STANLEY F. BAILEY University of California, Davis As a part of a study of California thrips it has been neces- sary to carefully review all the previous work done in order to accurately identify valid species and to avoid creating additional synonymy when describing new forms. In former papers the writer has reviewed other published works on western Thysanop- tera. The present report covers the species described by D. L. Crawford^. The two genera, the sixteen species, and five varieties described by Crawford are listed below in the order they appeared and un- der the names assigned them.

The writer has previously studied the types of Ankothrips rohustus D. L. Crawford, 1909 (Bailey, 1940 Pan-Pac. Ent. 16(3) :97-106) and Thrips abdominalis D. L Crawford, 1910 (Bailey, 1937, Canad.

The remaining species, Aeolothrips longiceps, Heterothrips decacornis, Anaphothrips longipennis, Dictyothrips reticulatus, Hoplandrothrips raptor, Liothrips mexicana, and Dicaiothrips angusticeps, have not to the writer’s knowledge been previously situdied and reported upon.

This species, represented on the type slide by two females, is distinct from all other species in this genus in that it has the scales on the posterior margin of the dorsum of the abdominal segments fused together (see fig. 4).

Anaphothrips zeae Moulton, U. S. D. A., Bur. Ent., Tech. Ser. 21:41, PI. 5, figs. 31-34. New synonymy. Two female specimens are present on Crawford’s type slide; one severely treated in eaustic, is mounted dorsally and the other ventrally. As is shown in figure 6 the cleared specimen shows an incomplete comb on the posterior dorsal margin of the eigthth abdominal segment. The ventrally mounted specimen has a fully developed comb as is the usual case in the species. Crawford’s original description did not mention this comb nor did he illustrate it. Moulton in his review of the North American species omitted longipennis (although other species of Crawford are listed) and did not compare zeae with it. The writer has studied a long series of this common species (ineluding macropterous males and brachypterous forms of both sexes) and notes that in some specimens the comb is very sparse and the number of bristles of the vein of the fore wing is variable (as are all the minor bristles on the head and pronotum) . One female speci- men has forked sense cones on the third antennal segment! Fig- ure 1 illustrates the dorsally mounted specimen of longipennis as it actually appears on the type slide and figure 3 the third and fourth antennal segments. There is no doubt that the two species are synonymous when normal variation is considered. Ctenothrips reticltlatus (D. L. Crawford) 1910. Dictyothrips reticulata D. L. Crawford, Pomona Coll. Jour.

C. reticidatus shows afl&nities with both Taeniothrips and Odontothrips ; the reticulations on the pronotum and particularly the dorsal ridge anterior to the ocelli, however, readily separate it from group II, D. of Taenio- thrips in Steinweden’s key.

Hoplandrothrips raptor, Hood, Entom. 48:102-107. Crawford’s illustration is of the head of the male of H. raptor and not of the female. The latter sex is illustrated in this paper (fig. 10) from the type slide which has on it one specimen of each sex, both ventrally mounted. The species in the genus Hoplandrothrips are most difl&cult to separate and Hood (1927, Entom. Amer. 7(n.s.) :230) states that “for some years I have busied myself in studying the species alive in the laboratory, and in rearing them; but the results accomplished lie more in the number of slides available for study than in any definiteness of concept regarding specific limitation.” From the limited number of species of this group in the writer’s collection, and the published descriptions of the others, raptor appears to be valid (Hood, 1941, Rev. de Ent. 12(3) :556, Brazil ) . It seems desirable, however, to supplement the original description as follows: The eyes are prolonged much more dors- ally than venfrally (see fig. 10) . The number of auxiliary bristles on the posterior margin of the fore wing is nine on the female and twelve on the male. At the base of the fore wing, on the anterior margin there are three strong bristles, all dilated at the tip on the female and on the male only the inner two dilated. As in most thrips of this group, the second antennal segment is darker than the first. The sense cone formula is as follows: HI, 1+2; IV, 2+; V, 1+1; VI, 1 + 1 (+1?). Faint reticulation can be seen in the center of the lateral margins of abdominal seg- ments one to six. The measurement of the principal bristles on the female are (in mm.) po, 0.0561; on the pronotum aa, 0.0594, nl, 0.0561, pa, 0.0726. July, 1944 ] BAILEY— THYSANOPTERA 89 Liothrips mexicanus D.

Hood raised mexicanus to specific rank in the above reference but did not expand its description or give any comparison with umbripennis or other species. Since Crawford devoted only a few lines to the original description (without illustration) it seems desirable to more fully describe and illustrate (figs. 9 and 11) mexicanus from the holotype female (ventrally mounted and partly cleared). Female (macropterous) . Length 2.288 mm. Color uniform dark brown. Antennal segments I and II concolorous with the body, III and basal half of IV clear yellow, remaining segments brown. All legs and tarsi brown. Wings brown in the basal half becoming gradually lighter toward the tip, marginal bristles light brown. Head about 0.247 mm. in length and 0.221 mm. in width behind the eyes. Mouth cone long and pointed extending beyond the pro- sternum. Cheeks nearly straight and faintly notched at margin. Dorsum of head with fine lateral striations near the posterior. Three ocelli present and compound eyes extending posteriorly somewhat more on ventral side than on dorsum. One postocular bristle, blunt at the tip. Sense cones on antennae as follows: III, 0-M; IV, 1-^2; V, 1 + 1 (-^1). Pronotum 0.104 mm. in length at center and 0.312 mm. in width at posterior angles; anastomosing lateral striations present on posterior. Four bristles on anterior margin, one mid-lateral, one at each posterior-lateral angle, and two somewhat forward of posterior margin. All bristles blunt at the tips. Fore femora en- larged and an appressed claw present on fore tarsus. Three strong, blunt bristles equal in length present on anterior margin of fore wing near its base. Fourteen interlocated or auxiliary bristles on posterior margin of fore wing. Measurements (in mm.) : Length of abdomen, 1.417 (including tube); length of tube, 0.195; postocular bristle, 0.079; midlateral bristles, 0.062; posterior-angular bristles, 0.112; antennal seg- ment I, 0.049; II, 0.066; III, 0.095; IV, 0.089; V, 0.085; VI, 0.072; VII, 0.066; VIII, 0.033; total length, 0.557. This expanded description is based on the type, slide No. 376, of the Canadian National Museum collected at Guadalajara, Mexico, by D. L. Crawford. Because of the size of the genus Liothrips and the difficulty of 90 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX NO. 3 determining species from some of the too brief, older descrip- tions (often inadequately illustrated), the writer is at present unable to give any synonymy for L. mexicanus. Moulton’s dumosa (also from Oak) appears closely related but this species likewise has never been clarified. Elaphrothrips angusticeps (D. L. Crawford) 1910. Idolothrips angtisticeps D. L.

Bull. 168:72. 1929. Elaphrothrips angusticeps, Moulton, Pan-Pac. Ent. 6(1): 12. This species has all the characteristics of the genus Elaphro- thrips Andre (1940, Proc. Ent. Soc. Wash. 42(4) :75-76) and is apparently distinct (based on the descriptions) from the three other Mexican species in this group: alhospinosus Moulton and teller Pr. are much smaller in size; dampfi Hood has much shorter interocular and postocular bristles; Crawford, however, did not state upon which sex his measurements were based. The type slide has mounted upon it two females and one male, all of which are badly broken up. The most intact speci- men (male) has been illustrated in fig. 8 as it actually appears. Crawford based his description on fifteen females and seventeen males from Belize, Havana, Cuba, San Marcos and Chinandega, Nicaragua, and Guadalajara, Mexico. Not all of this material has been available for study and it is quite possible that other species are among them. A detailed study of a series of the Central American species of this group should readily establish the validity of angusticeps. Of the two genera described by D. L. Crawford, Ankothrips is a well-established, valid genus. Of the twenty-one species and varieties described by him twelve are, as far as can be ascer- tained at present, valid. It is hoped that the new illustrations and expanded descriptions of those species in the more difiicult genera will enable other workers to more accurately place these and other related North American forms. With the exception of the type of Chirothrips mexicanus (Hood, 1927, Ent. News 38: 122; 1939, Rev. de Ent. 10(2) :464-466 Brazil), all of D. L. Crawford’s type material is at present deposited at Ottawa, Canada.

An- tennae with scape obscure yellow, remainder brown; flagellar seg- ments oval, rather strongly constricted at the sutures; verticils shorter than the segments; terminal segment pointed, only a trifle longer than the penultimate. Head with front and anterior vertex yellow; posterior vertex darkened and heavily pruinose; anterior vertex (female) nearly three times the diameter of scape. Pronotum brownish yellow. Mesonotum brownish yellow, the central portion of praescutum weakly darkened but not forming distinct stripes; posterior sclerites of notum similarly darkened. Pleura chiefly buffy, the posterior sclerites, and the pleurotergite more pruinose. Halteres with stem whitened, the knob abruptly dark brown. Legs with coxae and trochanters yellow; remainder of legs long and slender, yellow, the terminal tarsal segments passing into black. Wings strongly tinged with light yellow, the prearcular and costal fields clearer yellow; a large and very con- 92 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

News, 19:5-7; 1908), this fly runs to Limonia {Dicranomyin) citrina (Doane), an entirely different species. In its general appearance, especially the conspicuous wing stigma, the fly is more like L. {D.) ctenopyga Alexander or L. (D.) melleicauda (Alexander), but is quite distinct. Both of these latter forms have the male hypopygium unusually complex and it is possible that the male of the present fly will show a comparable condition. Besides the type, three further females from the same date and place were sent by Professor Macnab. These differ sufi&ciently from the type to make me unwilling to consider them as being conspecific, while at the same time agreeing in most details. In these specimens, three praescutal stripes are more or less devel- oped and vein 5ci is definitely longer. Oxydiscus (Oxydiscus) pacificus Alexander, new species Size large (wing, male, over 5 mm.) ; general coloration of tho- rax yellow, virtually unpatterned; antennae dark brown through- out; tibiae spurred; wings subhyaline, the stigmal area vaguely darkened; relatively abundant macrotrichia in outer cells of wing; cell Ml present; male hypopygium with the basistyle produced beyond the point of insertion of the dististyles as a long, obtusely- pointed lobe that is provided with unusually strong black setae; blades of gonapophyses relatively narrow; spines of ventral fork of aedeagus relatively short and straight, exceeding the short straight aedeagus. Male. Length about 4.5 mm.; wing 5.4 mm. Rostrum light brown; palpi darker. Antennae dark brown throughout, 16-segmented ; basal three flagellar segments enlarged, JULY, 1944] ALEXANDER— WESTERN TIPULIDAE 93 the second and third more or less fused, possibly indicating the beginnings of a fusion segTnent; succeeding segments passing through oval to elongate-oval, with verticils that much exceed the segments. Head dark brown; anterior vertex about three times the diameter of scape. Thorax almost uniform polished yellow, the central portion of praescutum a trifle more darkened but not forming an evident stripe. Halteres elongate, yellow, the knobs darkened. Legs with the coxae and trochanters pale yellow; remainder of legs brown- ish yellow, the terminal tarsal segments blackened; tibial spurs of middle and hind legs long and distinct (fore legs broken) ; claws simple. Wings whitish subhyaline, the stigmal area vaguely dark- ened; veins obscure yellow; trichia dark. Macrotrichia of outer cells relatively abundant, from cells to Cu, inclusive. Venation: Sci ending just before level of fork of Rs, Scz about one-third as long as Sci', Rs long; i? 2 + 3+4 about two and one-half times the basal section of Rs; R2 faint, apparently placed a little more than its own length beyond fork of i?2+3+4; cell Mi present, about one-third its petiole; m-cu beyond mid-length of cell 1 st M2, Abdomen dark brown, the posterior borders of the more proxi- mal sternites paler; hypopygium yellow. Male hypopygium with the basistyle produced beyond point of insertion of the dististyles as a strong, stout lobe, much longer and stouter than in ameri- caniis, obtuse at apex, provided with unusually strong and power- ful blackened setae. Outer dististyle unusually slender, at apex with a major axial spine, with a smaller subapical outer spine and a series of microscopic denticles on inner or lower margin before apex. Inner dististyle very obtuse at apex. Gonapophyses appear- ing as relatively narrow, subcultriform blades, narrower than in americamis. Ventral fork of aedeagus with the spine widely sep- arated at base, nearly straight, simple and unusually short.

Holotype, $ , Carlton, Meadow Lake Road, June 5, 1942 (Fender) ; Alexander Collection, through Professor Macnab. The present species is the first member of the genus to be discovered in the western Nearctic region. It is most similar to the eastern Nearctic Oxydiscas {Oxy discus) americanus (Alex- ander), differing especially in the larger size, body coloration, and, especially, the structure of the male hypopygium, as com- pared above. All of the known American species show strong hypopygial characters. Besides the four known at present from the eastern Nearctic, a few others are now known from Mexico, southward to Ecuador. 94 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

Professor James A. Macnab, to whom 1 am much indebted for many inter- esting species and records of Tipulidae from Oregon. The fly is very different from the other regional members of the genus, especially in the venation and the structure of the male hypo- pygium. The wing venation is much as in Pterochionea Alex- ander but the fusion-segment of the antennae is short, as in Cladura. In the light of this new discovery, it seems possible that Pterochionea will best be placed as a subgenus of Cladura Osten Sacken. Gonomyia (Idiocera) brookmani Alexander, new species Belongs to the blanda group; allied to calif ornica; rostrum darkened; antennae with scape blackened on lower face, yellow above; sublateral praecsutal stripes present; thoracic pleura con- spicuously striped longitudinally with yellowish white on a brown- ish gray ground; wings patterned with brown, as in the group; Ri +2 and R3 very closely approximated to confluent at wing margin; abdomen brownish black, the segments conspicuously ringed caud- ally with pale yellow; male hypopygium with the outer lobe of basistyle pale throughout, terminating in an acute pale spine; outer and intermediate dististyles blackened, both obtuse at tips.

The vertex is distinctly depressed just above margin, the margin being em- phasized by the depressed line. The first anteapical cell is quite short, the second is long. The male plates are long and tapered at apex as in OshorTiellus. The aedeagus is simple and not com- posed of paired structures as in Omanana. Genotype Premanus hebatus DeLong. This genus seems to be somewhat intermediate between Os- bornellus and Omanana, but in general appearance it resembles the latter more closely. Premanus hebatus DeLong, new species In general form and appearance resembling Omanana but with distinct vertex, color pattern and genitalia. Length 6-7 mm. Vertex produced, rather broadly rounded, more than twice as wide between eyes at base as median length. Color pale brown with dark brown markings. The ocelli are white between which in the female is a pale broken line. In the male there are only faint traces of this line. Just above ocelli is a black transverse band interrupted by a pale depressed transverse line. On basal half of vertex there is a round black spot next either eye and a broad longitudinal spot either side of middle. Pro- notum irrorate with dark brown. Scutellum pale brown with a white dash surrounded with dark brown in each basal angle, the apex, midway on each side between these, and one either side of middle on anterior margin equidistant from the spots in basal angle and from each other. Elytra smoky, veins dark brown and with a few white areolar spots. Spots along costa and apical margin dark brown. Face black with traces of pale arcs and a white band below ocelli in female.

Hartnack Publish- ing Co., Tacoma, Wash. 226+62+112+160 pp., illus., 1943. Price $12.00, plus 20c postage. This is Volume I of a comprehensive two- volume handbook on household pests. It is written in four parts, the first of which considers the more general features of the biology and ecology of household pests and their control. Part two takes up plants, both as pests themselves like the wood-rotting fungi, and in their rela- tion to animal pests. Parts three and four treat respectively of the invertebrates and the vertebrates, but exclusive of the insects, which are reserved for the second volume. Insects, however, loom very large in this first volume in connection with the introductory section on general principles and in relation with household plants and vertebrates; moreover, 92 pages in the section on invertebrates are devoted to crustaceans, myriapods, and arachnids, which come under the perview of the practical if not of the theoretical ento- mologist ! Dr. Hartnack’s ideal is that of a unified science of the plant and animal ecology of the household. He insists that one’s first step should be an understanding of the habitat relationships involved, and that only then is one in a position to effect control measures that are more than palliative and temporary in effect. Among some of the more unusual topics treated in the book may be mentioned sections on the origin of housepests, the climate of the house, the identification of pests by means of the traces they leave behind them of themselves and their activities, the decay of cadavers, and keratin or hair -eating pests. In addition there are, of course, the extensive materials on life-habits and methods of prevention and control that one expects such a book to provide. Like its predecessor, “202 Common Household Pests,” the present work is amply illustrated and indexed and printed on the best enameled paper. This attractive book should be available to all who are interested in or have occasion to advise others on problems related to the flora and fauna of the household. May the reception accorded it warrant its author in completing his second volume! — Melville H. Hatch. JULY, 1944] HATCH— STAPHLINIDAE 101 STUDIES ON NORTHWESTERN STAPHYLINIDAE I: ANTHOBIUM STEPH.

From allied species, farrarae is distinguished by its testaceous color, the first four abdominal segments of the male black, its densely punctate, alutaceous, ungrooved pronotum with arcuate sides, its unmodified sixth male abdominal segment, and its feebly dimorphic elytral apices. It is somewhat related to pothos Mann., which is the commonest species in western Washington, in which the pronotum is less densely punctate and grooved along the meridian line, the male with the first four and one half abodminal segments black, the fifth emarginate along its poste- rior margin, and the elytral apices scarcely at all sexually dimorphic. Anthobium (Eusphalerum) grayae Hatch, new species Color testaceous, the median portions of the head and pro- notum and the outer portions of the antennae dusky, the meso- and metathorax and abdomen piceous black, the latter slightly paler at the extreme apex in the male; head and pronotum punctate and alutaceous, the latter densely and strongly so, the elytral punctures larger and dense but not so clear cut; pronotum about three-fourths as long as wide, the apex about four -fifths as wide as the base, the front angles broadly rounded, the side margins broadly rounded in front, oblique or subsinuate in front of the narrowly rounded hind angles, the side feebly explanate toward the hind angles, the middle line more or less evidently grooved; elytra about two and one-half times as long as the pronotum, cov- ering four or more abdominal segments; the elytral apices in the male arcuately truncate, the outer angles broadly, the inner angles less broadly arcuate, in the female obliquely truncate, the sutural angles slightly divergent and narrowly arcuate, the apical margin just laterad to the sutural angles feebly sinuate; male with the sixth ventral abdominal segment emarginate along the posterior margin, the seventh ventral consisting of a broad median lobe and JULY, 1944] HATCH— STAPHLINIDAE 103 a narrower longer lateral lobe on either side; hind tarsi with the first four segments subequally short, together shorter than the fifth; length 2.1-2.25 mm.

This species is distinguished from other American species of the subgenus Eusphalerum by the slightly sinuate apices of the female elytra. From farrarae and pothos it is furthermore dis- tinguished by its dusky head and pronotum and black female abdomen. Anthobium (Anthobium) bonnelli Hatch, new species Piceous black, the elytra and appendages testaceous; head and pronotum finely distinctly punctate, the pronotum more evidently alutaceous than the head, the elytra more coarsely but less dis- tinctly punctate than the head and pronotum; pronotum about seven-tenths as long as wide, the apex seven-tenths as wide as base, the sides evenly arcuate, the fore and hind angles broadly rounded, the side margin feebly explanate in front of the hind angles; elytra (male) two and one-half or more times as long as the pronotum, covering the three or four basal abdominal seg- ments, the apices broadly arcuate into the more narrowly arcuate sutural angles; elytra (female) more than three times as long as the pronotum, longer than the abdomen, the apices broadly curving into the acutely produced slightly divergent sutural angles, the apical margin just la ter ad to the sutural angle strongly sinuate; male with fifth abdominal segment unmodified, the sixth abruptly and semi-circularly thickened at the middle, the semi-circular area being separated from the posterior edge by a narrow membranous margin; hind tarsi with the first four segments subequally short, together shorter than the fifth; length 1.8-2.25 mm.

By its dimorphic elytra and the structure of the sixth abdom- inal segment in the male, this species is related to tihiale Csy. from Arizona, from which it differs by its more strongly arcuate pronotal side margins (subparallel, very feebly arcuate in tihi- ale) and longer male elytra (about twice as long as the pro- notum in tihiale, exposing four abdominal segments, as opposed to only two or three in honnelli ) . 104 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

Type male, allotype and one paratype female: Olympic Hot Springs, Wash. May 31, 1931, M. H. Hatch. Ten additional paratypes; Cooks, Lake Crescent, Lewis and Clark State Park, Seattle, and Swauk Creek (Kititas Co.), all in Wash- ington. Related to fraternum Casey from northern California by the fissure of the posterior margin of the fifth ventral abdominal segment in the male, but distinguished therefrom by the black color of the four basal segments of the male abdomen, which is pale in fraternum. Casey makes no mention of the fissure in his species being itself at the apex of a triangular incision, as in minskae. In farrarae and minskae described above and in such previ- ously described species as convexum Fauv. and fraternum and punctatum of Casey the structure of the tarsi is such as to raise the propriety of retaining them in Anthobium. In these species the first two segments of the tarsus are longer than the next two, the first four together longer than the fifth. I leave the problem to future students of the group. JULY, 1944] BEER— OREGON ACMAEODERA 105 NOTES ON THE HOSTS, HABITS AND DISTRIBUTION OF OREGON ACMAEODERA (Coleoptera, Buprestidae) BY FRANK M. BEER Salem, Oregon This paper is a record of the Acmaeodera of Oregon, mainly collected by the writer during the past seven years. A majority of the species have been taken in the Rogue River Valley where they inhabit their usual hosts which encroach from the Sierra Nevada Range and adjoining foothills. The earlier records for the state are woefully incomplete, the species in reality occurring far more commonly and abundantly than previous reports would indicate. Dr. Chamberlin’s^ paper in 1929 was the last to report this genus and list new material actually taken by an Oregon col- lector. In his catalogue, Chamberlin^ lists four species found in Oregon, and an additional one, flavosticta, as doubtful, while Barr^ lists five in his recent excellent resume. After intensively collecting through the state the number of species has been increased to fourteen and two varieties, and the range of several materially extended. Since a large part of the collecting was done during the winter and early spring by cutting the adults from their pupal cells and a few having been reared from larvae, exact host plants can be given for the majority of the species. Though host plants may not in general be consid- ered to have a great deal of significance, however, after much careful observation, the species have been consistently found in- habiting the same host plant or plants. Acmaeodera acuta LeConte This species is by far the most common collected in south- western Oregon. It is generally found feeding on the flowers of Eriophyllum lanatum (Pursh) Forbes, a yellow composite oc- curring in the foothills of the Rogue River Valley and southward across the Siskiyou summit into California. The insect also oc- ’ Chamberlin, W. J., 1929, Remarks of the Buprestidae of the North Pacific Coast Region with descriptions of new species, Pan-Pac. Ent., 5:111. - Chamberlin, W.

XX NO. 3 curs in the Willamette Valley as occasional specimens have been taken on the blossoms of wild rose {Rosa pisocarpa Gary) . The larvae mine the smaller dead branches and stems of the Garry oak {Quercus garryana Dough) from which adult specimens have been cut. AcMAEODERA ANGELICA FaLL Numerous specimens of this little Buprestid have been taken in southwestern Oregon, most of them beaten from the foliage or dug from dead wood scars of buckbrush {Ceanothus cuneatus Nutt.), though a few have been cut from dead branches of Cali- fornia black oak {Quercus californica [Torr.] Coop.) The variety nexa Fall occurs through the same region and has been taken from buckbrush. Recently a specimen was reared from mountan mahogany {Cercocarpus betuloides Hook.). Acmaeodera bishopiana Fall The only record we have of this species is of three specimens taken by Mr. M. C. Lane at Adrain, Oregon, on May 28, and re- ported by Dr. W. J. Chamberlin It apparently occurs through- out the Great Basin region, as the original specimens came from Owen’s Valley, California, and the writer has specimens reared from the Walker Lake region in Nevada. The host in its southern range is the wingscale {Atriplex canescens [Pursh] Nutt.). This plant extends northward into Oregon. Acmaeodera connexa Fall This species occurs commonly through the southwestern part of the state wherever the host plant is found. Many adult speci- mens and numerous larvae have been dug from the scars and dead trunks of the Garry oak {Quercus garryana Dough). Dur- ing June, it can be taken on one of the willow herbs {Epilohium sp.) and occasionally on the composite, Eriophyllum lanatum (Pursh) Forbes. \ Acmaeodera fenyesi Fall This uncommon form has not previously been recorded from the state and to my knowledge the host plant has not been re- ported. The species is apparently quite rare in our range as ^ Chamberlin, W. J., 1929, Pan-Pac. Ent., 5 :111. JULY, 1944] BEER— OREGON ACMAEODERA 107 literally days of cutting thruogh manzanita {Arctostaphylos viscida Parry) has produced only seven specimens. These are somewhat larger than specimens from southern California, and one female is noticeably more maculate. All specimens have been taken from the foothills of the Rogue River Valley. Acmaeodera gemina Horn Though this species is never taken in abundance, it is occa- sionally found feeding on several varieties of flowers or is swept from grass. Careful search over several years has not revealed its host. The species has been taken from the floor of the Rogue River Valley to the high mountains in the vicinity of Crater Lake. The variety nehulosa Horn is apparently rare in this region, as only one specimen has been taken, that from near Crater Lake. Acmaeodera hepburni LeConte This is another common species which has a wide range of distribution. It is found throughout the foothills of southwestern Oregon' where its larvae infest the Garry oak [Quercus garryana Dough). It is also taken abundantly on the flowers of the com- posite Eriophyllum lanatum (Pursh) Forbes, along with acuta, connexa and labyrinthica. Acmaeodera labyrinthica Fall Many specimens of this beautiful species were collected in the Siskiyou Mountains of southern Oregon, the specimens being most numerous on the upper Applegate in the vicinity of Copper, Jackson County, near the Oregon-California line. Two specimens were dug from dead scar tissue of living Garry oaks {Quercus garryana Dough). In early June many specimens were taken feeding on the blossoms of Eriophyllum lanataum (Pursh) Forbes. This species is considered as distinct by some writers and as a variety of connexa or acuta by others. However, in any series it can be easily distinguished by its breadth and bronze lustre. In the last respect it more closely resembles hepburni, from which it differs by the shape of the pronotum and the emargination of the prosternum. A rather interesting observation was made upon the group acuta, connexa, hepburni and labyrinthica which would seem worthy of mention. Numerous specimens of labyrinthica with lesser numbers of acuta, connexa and hepburni were observed on 108 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX NO. 3 three occasions while they were feeding on the previously men- tioned yellow composites. During this time numerous pairs were seen mating, hut at no time did specimens outside the species succeed in copulating, though occasional attempts were made. Although the four species are distinctive enough to he separated on external features, this hit of information lends more proof to the helief that there are four distinct species. AcMAEODERA MARIPOSA HoRN This distinctive species is not abundant, hut a couple of dozen specimens have been taken. About one-half of them have been dug from their pupal cells in mountain mahogany [Cercocarpus beta- loides Hook.) where they work through dead trunks or through dead patches in living trees. During the spring of 1940, several specimens were swept from the foliage of antelope brush {Put- schia tridentata [Pursh.] D. C.) on Roxy Anne Butte, five miles east of Medford, Jackson County, Oregon. All specimens have been taken on or near the floor of the Rogue River Valley, none apparently occurring above 2500 feet elevation. Acmaeodera plagiaticauda Horn Because this species is seldom obtained while sweeping it is considered rare. After learning the habits of the larvae, and col- lecting accordingly, recently transformed adults are quite easily obtained by cutting through the dead patches of manzanita [Arctostaphylos viscida Parry) . It ranges over most of south- western Oregon, extending as far north as Azalea, Douglas County. Acmaeodera purschiae Fisher This species was first found in the state near Medford, Jackson County, where two specimens were cut from antelope brush {Purschia tridentata Pursh.). On June 12, 1940, about thirty specimens were taken while sweeping the host plants on Roxy Anne Butte, Jackson County. Previously, five specimens had been cut from the host plant at the base of Mount Shasta, near Weed, Siskiyou County, California. The range of this spe- cies is thus extended northward by several hundred miles and into a third state. JULY, 1944] BEER— OREGON ACMAEODERA 109 AcMAEODERA SINUATA VAR. SEXNOTATA VaN DyKE Numerous specimens of this beautiful variety have been col- lected, all having been dug or swept from buckbrush {Ceanothus cuneatus Nutt. ) . They range over most of southwestern Oregon, especially through the Siskiyou Mountains. No examples of the species sinuata Van Dyke have as yet been taken. AcMAEODERA VANDYKEI FalL This widely distributed species has seldom been found in its pupal cell. It is not common but is found throughout the por- tion of the state where the deer brush {Ceanothus integerrimus H. & A.) occurs. One specimen was also taken from sticky laurel {Ceanothus velutinus Dough), which must also be listed as a host plant. Specimens have been taken in the Wallowa and Blue Mountains of northeastern Oregon, Hood River County, and south along the eastern slope of the Cascade Range, and across into the Rogue River Valley and the adjoining foothills. AcMAEODERA VARIGATA LeCoNTE This species has the widest distribution in the state. Speci- mens have been taken from the following Oregon counties: Douglas, Grant, Hood River, Jackson, Josephine, Klamath, Lake and Wheeler. The specimens have been cut from two species of mountain mahogany {Cerococarpus betuloides Hook, and C. ledifolius Nutt.) and from service berry {Amalanchier sp.) and are generally found above 3000 feet in elevation. Two varia- tions are noticeable, the specimens cut from service berry are smaller and the specimens taken near Glendale, Douglas County, are more abundantly maculate. I am indebted to Mr. James H. Baker of Baker, Oregon, for permission to include a series of fourteen specimens of A. vari- egata Lee. from his collection. Nine of these were taken near Baker, Baker County, the other five were collected at Hiatt Lake, Jackson County. His series, which is typical, thus extends the species into the northeastern comer of the state. 110 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XXNO. 3 A NEW DOBSONFLY(MEGALOPTERA)FROM CALIFORNIA BY EDWIN C. VAN DYKE California Academy of Sciences, San Francisco, California In 1908, Banks published a paper on the classification of the Corydalinae, in which he defined the various genera of the group, at the same time establishing two new genera at the ex- pense of older genera. One of these was Neohermes which was to include the following previously described species: fHicornis^ Banks, the genotype, calif ornicus Walker, angusticollis Hagen, cinerascens Blanchard, and humeralis Banks, The genus Neohermes is defined by Banks as having the anal vein of forewings with two forks, the anal cells subequal in length, the lower with two veins, the upper with one, and no cross vein between the first branch of the anal vein and the vein from anal cell, the costal cells about as long as broad, the antennae as near to the ocelli as to the eyes, the branches of the median vein simple, and but three cross veins from radial sector to radius. Neohermes nigrinus Van Dyke, new species Of moderate size and entirely black except the anterior part of head which is somewhat fulvous and a few cross veins on the outer portion of both wings which are white. Head widest across eyes which are of moderate size and protuberant, convergent in front and gradually narrowed behind, the ocelli conspicuous, and with two elongate callosities centrally located behind; antennae fili- form, with segments slightly longer than broad and somewhat moniliform, and almost three-fourths length of forewing. Pro- thorax longer than broad, with sides parallel and disk opaque except for sides and medial area behind, which are smooth and shining. Wings about four times as long as broad, the hind pair with sides more parallel as usual. The wing venation agrees with the genus and such typical species as calif ornicus Walker. Holotjpe (No. 5430, Mus. Calif. Acad. Sci., Ent.) and one paratype. Holotype, expanse of wings, spread, 5 cm. 2 mm., length of body 2 cm. ; paratype, expanse of wings 4 cm. 2 mm., length of body 1 cm. 5 mm. Both specimens were collected by me at Richardson’s Spring, Butte County, California, the holotype. May 12, 1944, and the paratype May 18, 1944. The black color, moderate size, a rather small head as com- pared with californicus, and simple filiform antennae should readily separate this species from any of the others in the genus. ’ According to Weele, Coll. ZooL, Selys Longchamps, 1910, filicornis Banks as also angusticollis Hagen, concolor Davis, and minutus Davis are synonyms of cali- fornicus Walker, therefore the last would be the genotype. JULY, 1944] LINSLEY AND USINGER— ARADIDAE 111 FURTHER NOTES ON THE HABITS OF SOME FLAT BUGS WITH A DESCRIPTION OF THE MALE OF ARADUS PATIBULUS VAN DUZEE (Hemiptera, Aradidae) BY E. G. LINSLEY AND R. L. USINGER University of California The following observations on aradids were made between May 10th and June 15th, 1942, in the Sierra Nevada Mountains of Madera and Mariposa counties in the vicinity of the south entrance of Yosemite National Park, California. As in our previous paper,^ biological observations are by E. G. Linsley, taxonomic notes and identifications by R. L. Usinger. Aradid spring dispersal flights were observed at Miami Ranger Station, Madera County. The flights began on May 19th, which was the third of three successively warmer days after the end of the spring snow storms and rains. On May 19th, the flight began at approximately 5 P.M. P.S.T. and was over by 6:15 P.M. A sample of 102 specimens was taken. This included 6 species, of which 51 per cent of the examples were Aradus behrensi Bergr. On May 20th a second flight occurred. The day was warm but overcast in the late afternoon. The flight began at approximately 4 P.M., was over by 5:30 when the temperature began to fall. The same sampling method yielded only 39 examples of two species, with A. behrensi again predominant. On May 21st, a third flight occurred, this time on a warm but wholly overcast day. The flight began at about 4 p.m., lasted until approxi- mately 6:00. Forty-three examples were taken representing six species, of which more than 50 per cent were again behrensi. On this date three species appeared which had not been repre- sented in previous samples. This was the last flight observed. On both May 22nd, and 23rd, one example of behrensi was taken but no further examples were captured in flight between May 23rd and June 15th (termination of observation) . Associated with the aradids in their dispersal flights were numerous species of Coleoptera (fig. 1). Although the samples ^ Linsley, E. G. and R. L. Usinger, 1942.

XX NO. 3 obtained are too small to be of significance as far as most of the individual species are concerned, the totals clearly indicate that the flights of these insects as a group were correlated with those of the aradids. Of further significance would appear to be the fact that the majority of these species are bark inhabitants, as are aradids, the remainder mostly wood borers. This suggests that the same factors which initiate aradid dispersal also influ- ence emergence of other insects which occupy the same habitat. ARADINAE , Aradus ampliatus Uhler This species was not encountered until the third day of dis- persal flights. This is of interest in view of the fact that in the Mt. Lassen area adults were taken in flight two days prior to the flights of other species. Aradus patibulus Van Duzee Taken in flight only on May 19th. Adults later found under bark of western yellow pine at Fish Camp, Mariposa County. Not previously observed in dispersal flight. Male. Antennae and pronotum as in the female (Usinger, Ann. Ent. Soc. Amer., 29:515, plate 1, fig. 4A, 1936) but size smaller, 7 mm. long, 2^ mm. wide across pronotum, and 3% mm. wide across the abdomen. Male genital capsule similar to that of ampliatus Uhler (Usinger, Loc. cit., fig. 4) but narrower than long, 27 : :29; more narowed basally with shallower, rounded basal sinuation ; and apical lobes a little more strongly produced, extending beyond general contour of abdomen.

XX NO. 3 Aradus debilis Uhler Small flight on May 19th. This species overwinters as adults or last instar nymphs. First instar nymphs were found on Polyporus volvatus fungi on fallen western yellow pine on May 28th, 9 days after the dispersal flight was observed. Adults were also found in large numbers on the dark upper surface of the fungus, Pomes penicola, on fallen white fir at Mariposa Big Trees, June 6th. Because of perfect cryptic coloration they were very difl&cult to detect and several minutes were required to com- plete examination of each fungus. The maximum number of individuals encountered on a single fungus was fourteen. Aradus blaisdelli Van Duzee In flight on May 19th. Dispersal flight not previously recorded.

JULY, 1944] TILDEN AND MANSFIELD— COENONYCHA 115 NOTES ON THREE SPECIES OF THE GENUS COENONYCHA HORN ( Coleoptera, Scarabaeidae) BY J. W. TILDEN AND G. S. MANSFIELD In view of the somewhat limited information available on species of the genus Coenonycha Horn, it was thought the fol- lowing notes concerning three recently described species might prove of interest. The type series of C. howlesi Cazier was collected about three miles northeast of Benton, Mono County, California, by J. W. Tilden and C. W. Bowles. The first specimens taken were at- tracted to a gas lantern at dusk. The remainder were collected from the tips of Artemisia tridentata, one person collecting while the other held the light. Most of them had the forelegs extended, a habit common to species of this genus. They seemed indifferent to light that was held on them, though some were attracted to the light if it remained stationary for a period of time. The vegeta- tion of this area is predominantly Artemisia tridentata, with an admixture of other bushy composites. C. howlesi may occur on other plants, although to date it has not been taken elsewhere. C. testacea Cazier, described from Cuyama Canyon, Santa Barbara County, California, was taken in large numbers about ten miles west of Simmler, San Luis Obispo County, by the authors on March 20-22, 1940. This species was closely associ- ated with Eriogonum fasiculatum here as in the type locality. On each of the three evenings in the Simmler area the first speci- mens noted came to a gas lantern shortly after sundown. Mat- ing pairs were observed about dark and commonly later in the evening. The insects were taken in numbers from the tips of the plants, and normally sat with the forelegs extended as in howlesi. They have well developed flight wings but seem averse to flying. The number taken at light was very small in proportion to the popu- lation that was found to exist in the immediate area. The few that came to light must have flown there, since the collecting sheet was clear of the ground. Specimens were taken from the plants until about 12:00 P. M. No doubt they could have been taken later, although we found the insects less numerous in the late hours than they were earlier in the evening. 116 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX NO. 3 A third species, C. ampla Cazier, was also found near Simmler, but on Juniperiis californica, the only tree in the vicinity. The first was taken by beating about 10:00 P. M., March 21. Exten- sive beating and inspection yielded several others on the same night. On the succeeding night, these were observed carefully. At first we thought them rare, since so few were found, but one location was discovered where about 18 were taken. Though relatively common, they did not approach testacea in numbers, in this area at least. Careful approach enabled us to observe these insects without disturbing them. Each was found at or near the tip of a twig. This species proved to be negatively phototropic. They would nearly always drop at the close approach of the light, or would edge around to the other side of the twig. They were seen to extend their forelegs as did the other two species. It was noted also that they dropped if our breath was blown on them. Whether this was due to objection to the air current or to another factor we do not know. At first no feeding was observed. It occurred to us that this might be due to the light. Such proved to be the case. When the light was weakened, the beetles became active and fed. When in moderate to strong light they suspended activity. One of us obsrved while the other slowly removed the light. The beetle was seen to crawl deliberately along the limb and begin to feed. With a slow return of the light, the beetle first ceased to feed, then stopped all movement, and as the light grew stronger, ex- tended its legs and dropped to the foliage beneath. It made no effort to extricate itself from the position in which it landed as long as the light was present. With the removal of the light, activity was resumed gradually. Several were observed to behave in this same manner, and although the quiescent individuals were conspicuous at all times, they made no effort at concealment. This habit might easily lead to their dropping before being taken by beating, and it seems likely that the species is more common than our collecting results show. All three were found at the tips of their respective forage plants with forelegs extended, but in the case of ampla this ap- peared to be the first stage in a negative response to light, for with an increase in the intensity of the light they extended the other pairs of legs as well, and dropped from the trees. JULY, 1944] TILDEN— PHOEBIS SENNAE MARCELLINA 117 None of these species was found in daytime, all activities of mating and feeding being strictly nocturnal, nor were any taken on any plant other than the one listed for each species. BREEDING OF PHOEBIS SENNAE MARCELLINA CRAM. IN SAN JOSE, CALIFORNIA ( Lepidoptera, Pieridae) In October, 1941, Piazza first noted larvae of this species on cultivated shrubs of Cassia tomentosa, and later located pupae and eggs. Reared specimens emerged continuously during the fall. Piazza and Tilden took a considerable number of all stages from a shrub of the same species, on December 2, 1941, and these were reared by Tilden. From 17 chrysalids removed from the shrub and kept indoors, 2 perfect males, 4 perfect females emerged, while 6 females emerged with damage from defective chrysalids. Two chrysalids were parasitized. Three failed to produce adults. Emergence dates range from December 4 to January 9 (1942). The propor- tion of females seems unusual, there being 8 females and 4 males, a ratio of 2:1. Adults reared from specimens collected as larvae emerged in better condition than those obtained from specimens that had pupated before being taken, suggesting probable damage to the chrysalids in removing them from the food plant. Emerged specimens refused to mate in captivity. Eggs taken on December 2 did not hatch before the project was abandoned in June, 1942. All specimens taken as larvae matured and pu- pated; some still had not emerged in June, indicating a long pupal stage under some conditions. Although adults of P. s. marceilina Cram, have been noticed repeatedly in the San Jose area over a period of several years, this appears to be the first time that the entire life cycle has been observed at any locality so far north. Santa Barbara County is given by Dr. J. A. Comstock as the usual northern limit of the (breeding?) range. It is possible that the species may be establishing itself in the San Jose area, probably due to the cultivation of suitable food plants, which enable stragglers of this strong-flying butterfly to form at least temporary colonies north of its normal range. — J. W. Tilden. 118 THE PAN-PACIFIC ENTOMOLOGIST [vOL. XX NO. 3 A BRIEF NOTE ON THE HABITS OF AMOBIA (PACHYOPHTHALMUS) FLORIDENSIS TOWNSEND (Diptera, Sarcophagidae) BY E. GORTON LINSLEY University of California, Berkeley Amohia {Pachyophthalmus) floridensis Townsend appears to be a common inhabitant of the nests of Sceliphron servillei (Sauss.) in California. On numerous occasions the writer has found pupae of what was apparently this species in the mud cells of this wasp. In February, 1944, however, in connection with another study, large numbers of Sceliphron nests from vari- ous localities in the San Joaquin Valley were examined and a small percentage from each locality contained pupae of this fly. Pupae were found in sealed cells under conditions suggesting that larvae or eggs were deposited during the provisioning period. The larvae had apparently fed on the Sceliphron larvae as well as on the stored spiders. Seven adults reared on April 4 from a cell series taken under a culvert at Chowchilla, Madera County, on February 15, were sent to H. J. Reinhard, v/ho identified them as Amohia {Pachyophthalmus) floridensis Townsend. Allen^ summarizes the known habits of Pachyophthalmus as follows: “The members of the genus, so far as known, are biologically superimposed on wasps which build mud nests under shelter or in hollow stems, including members of the families Sphecidae and Eumenidae. The manner in which the female establishes her progeny and the subsequent larval development have not been ob- served. Rau found the puparia of one species lodged in a hollow stem containing the nests of Odynerus. When associated with the common “dirt daubers” Pelopaeus and Trypoxylon, which build their nests indoors, it is not known whether the maggots pupate within the. mud cells of their hosts or leave them to seek other shelter for the transitional stage. The members of the genus Pachyophthalmus are more distinctly aerial in habit than the other North American genera of Miltogrammini. So far as is known, all of the activities of adult, larval, and pupal stages take place in a stratum extending from a foot or more to several feet above the ground. This is a noteworthy biological specialization in a group of flies, most of which pass the immature stages underground, and never rise, as adults, but a few inches above the ground.” A. {P.) floridensis has been previously recorded from cells of Sceliphron cementarium (Drury) in Maryland and Mississippi. ^ Allen, H.

JULY, 1944] HEMMING— NOMENCLATURE COMMISSION 119 RECENT WORK BY THE INTERNATIONAL COMMISSION ON ZOOLOGICAL NOMENCLATURE BY FRANCIS HEMMING Secretary to the International ComTnisisoyi on Zoological Nomenclature The International Commission on Zoological Nomenclature are now engaged in the publication of decisions taken before the out- break of war in 1939. These decisions have been embodied in Opinions 134-183 and Declarations 10-12. Of these, Opinions 134- 155 and the three Declarations have already been published or are in the press. The remainder are ready for printing and will be published as soon as funds are available. These Opinions are of particular interest to entomologists, since in addition to nine Opinions relating to the interpretation of vari- ous aspects of the International Code, no less than 38 of these Opinions are directly concerned with entomological subjects. The Opinions relating to the interpretation of the Code are: Opinions 138 (meaning of phrase “definite bibliographic refer- ence" in Article 25) Opinion 141 (naming of families) ; Opinion 145 (status of names first published in invalid works) ; Opinion 147 (generic names of same origin and meaning as older generic names) ; Opinion 148 (status relating to names published as emen- dations of, or substitutes for, older names) ; Opinion 164 (position as regards types when two or more genera are united) ; Opinion 168 (supplementing Opinion 65 regarding genera based upon erro- neously determined species) ; Opinion 172 (status of type — desig- nations of genera in abstracts, etc.) ; and Opinion 183 (interpreta- tion of Article 8 relating to form in which generic names should be published) . Of the Opinions specially concerned with entomological subjects, six deal with the status of particular works or with the dates of such works: Opinion 136 (Latreille, 1810) affects all Orders of insects; Opinion 135 (“Erlangen List," 1801) is of special interest to hymenopterists ; Opinions 134 (Freyer, Neue Beitrdge) , 138 Hubner, Sarmnl. exot. Schmett., 1807 and Fabricius Mag. Insek- tenk. (Illiger) 1807) and 150 (Hubner, Verz.hek. Schmett) are concerned with Lepidoptera and Opinion 152 (Meigen, 1800) with Diptera. Opinions 140 and 143 deal with certain family names in insects. The remaining 30 Opinions deal with particular generic names in various Orders of insects. These Opinions either fix the types of these genera or add the names to the Official List of Generic Names in Zoology, or do both. Three of these Opinions are con- cerned with Orthoptera; 13 with Hymenoptera and 14 with Lepi- doptera. Each Opinion is published separately but Opinions are consecu- 120 THE PAN-PACIFIC ENTOMOLOGIST [vOL. XXNO. 3 lively paged to facilitate the publication of an index on the com- pletion of the volume concerned. The International Commission are most anxious to secure that O'pinio'ns are published as rapidly as possible but they are greatly hampered by lack of funds. The Commission therefore appeal to scientific institutions and individual scientific workers for dona- tions to a special fund to be used for the issue of publications. Full particulars of this appeal are given in Part 2 of the Com- mission’s official organ, the Bulletin of Zoological Nomenclature, published in 1943. Contributions, however small, will be warmly welcomed and will be acknowledged in the Bulletin. Bankers’ drafts, checks, and money orders should be made payable to the International Com- mission on Zoological Nomenclature and sent to the Commission at their publications office, 41 Queen’s Gate, London, S.W.7. All orders for the Commission’s publications should be sent to the same address. Inquiries relating to the work of the Commission should be addressed to me at 83 Fellows Road (Garden Flat), London, N.W,.3. CLOVER LEAF WEEVIL IN CALIFORNIA The clover leaf weevil, Hjpera punctata (Fab.), an introduced species, has spread over much of California and occurs on both cultivated and uncultivated areas. Although acreage of clover in this state is very limited, the spring brood is common on Melilo- tus and other wild clovers. We have records of its presence on alfalfa in only the following counties; Alameda, Butte, Merced, Sacramento, San Joaquin, Stanislaus, and Yolo. Its presence can be expected on alfalfa anywhere it is grown in northern and central California and in some parts of southern California. However, the clover leaf weevil has not caused economic damage to alfalfa in California although it has been reported as an im- portant pest of clover and alfalfa in other sections of the United States. On only two occasions have we found it in abundance in California. Once it was found commonly on Melilotus indica growing along a roadside on the lower southern slope of Mt. Diablo, Contra Costa County. More recently (July, 1941) it was taken in the same area on a very small patch of dry-farmed young alfalfa. Our climatic conditions in the spring are appar- ently so favorable for the development of a fungus disease that destructive numbers are generally checked before serious damage occurs. Limited acreage of clover may also partially account for the fact that this insect is not an important pest in California. — Ray F. Smith and A. E. Michelbacher.

XX, No. 4 October, 1944 NOTES ON THE NORTH AMERICAN SPECIES OF THE ZODION FULVIFRONS GROUP (Diptera, Conopidae) BY SIDNEY CAMRAS Chicago, Illinois In a previous paper (Ent. News, 54:187-191, 1943) the Oblique-fasciatum Group species has been covered and the sources of material acknowledged.- As a result of the present study of the large series of specimens that has been aggregated, a number of species previously recognized appear to be synonyms. Some of these may prove to be separable in the future, and the necessity of depending on descriptions, since most of the types have not been seen, increases this possibility; but I believe that the present contribution will aid considerably in a better under- standing of this difficult group. While the majority of specimens fail into definable species, individual variation frequently over- laps two species so that an artificial line of division must be established. This refers to species occurring in the same region as well as to intermediates between geographical races. ZODION FULVIFRONS SaY Zodion fnlvifrons Say, 1823, Jour. Acad. Nat. Sci.

XX, NO. 4 This species is characterized by the larger size: usually 6-8 mm.; the short, wide, thick female genital plate; and the reddish abdomen of the male. The female abdomen is usually dark, but may be reddish on the basal segments. The first posterior cell is practically always open. There are two main forms of this species. One has the dorsum of the thorax covered with bluish pollen and with two dark lines ; the other has more brownish pollen and five lines on the dorsum of the thorax {= sayi) . Most individuals however are somewhat intermediate, and the intergradation is complete. With the de- crease in thoracic lines and more bluish pollen, the abdomen is usually more reddish, and the proboscis tends to become longer. Such individuals are more common in the West. A further ex- treme are those examples with so much pollen that the dorsal thoracic lines are indistinct. Obscurum seems to be based on such specimens. In the past, it has been considered that the abdomen of the male of this species may be reddish or entirely dark; but I have found no contra-indication to referring all specimens with en- tirely dark abdomens to intermedium, although there is com- plete intergradation between the two types. There is also com- plete intergradation between this and a smaller species for which the name ahitus is used here. Formerly, abdominale was used for this smaller species, but the name clearly belongs to a species “rather more than one-fourth of an inch” in length. The speci- men mentioned by Say under abdominalis as “less than half the above size” does of course belong to the smaller species. I have set the dividing line between the two species at 5^2 mm., but the majority of individuals are well above or below this size. I have examined the type of lativentre and find it to be a greasy specimen of the present species. Bilineatum based on an example with a very long third antennal joint, will, I believe, prove to be an aberrant individual. Distribution: Southern Canada, United States, and Mexico. 363 specimens examined. ZODION INTERMEDIUM BaNKS Zodion intermedium Banks, 1916, Ann. Ent. Soc. Amer. 9:193 (Pennsylvania: Pocono Lake). Zodion occidentale Banks, 1916, Ann. Ent. Soc. Amer. 9:194 (Ore- gon: Montaville). OCT. 1944] CAMRAS— ZODION 123 Zodion reclusum Banks, 1916, Ann. Ent. Soc. Amer. 9:194 (Cali- fornia: Redlands). Zodion basalis Van Duzee, 1927, Proc. Calif. Acad. Sci., 16:586 (Idaho: Moscow Mountains). This specieg differs from fulvifrons by the long, narrow, thin female genital plate, and the entirely dark abdomen of the male. As in fidvifrons there is similar variation in the thoracic lines and length of the prosboscis. Basale is based on indistinct thor- acic lines, and reclusum on a long proboscis. There is a certain amount of variation in the size and shape of the genital plate, and intermediates bridge intermedium with occidentale. The relative length of the genital plate is frequently deceptive, and when the abdomen is extended may resemble that of perlongum which is proportionately longer and narrower. The border of dark striations is narrow in intermedium and perlongum, but very wide in fulvifrons. Distribution: Southern Canada and United States. 162 speci- mens examined. Zodion perlongum Coquillett Zodion perlongum Coquillett, 1902, Canad. Ent., 34:199 (Nerv Mexico: RioRuidosa). This species is characterized by its large size: 7-9 mm.; very long, narrow, thin female genital plate; and the long, narrow abdomen due to the third and fourth abdominal segments which are longer than wide. This species is known with certainty only in the female sex. The males are probably large individuals with reddish abdomens that cannot be distinguished from fulvifrons. Distribution: United States and Northern Mexico. 22 speci- mens examined. Zodion abitus Adams Zodion abitus Adams, 1903, Kans. Univ. Sci. Bull., 2:33 (Kansas). Zodion bicolor Adams, 1903, Kans. Univ. Sci. Bull., 2:35 (Kansas Douglas County). This species is characterized by its small size: usually 4%-5 mm., reddish abdomen of the male, and usually closed first posterior cell. The abdomen of the male is usually entirely reddish except for the first segment, with yellow pollen on the sides and distal 124 THE PAN -PACIFIC ENTOMOLOGIST [vOL. XX, NO. 4 segments. Some specimens have dark markings representing in- tergradation with the entirely dark male abdomen of cinerei- ventre. Such individuals and those with an open first posterior cell are more common in the Western portion of the range of the species. The first posterior cell varies from narrowly open to petiolate as long as the anterior cross-vein. The palpi are short, not clavate, and about as long as the width of the proboscis. The use of the name abitus instead of abdominale is explained under fulvifrons. Abitus is based on the female, and bicolor on the male. Distribution: Southeastern Canada and Eastern United States, west to Colorado (Boulder, Buena Vista, Ridgway). 73 speci- mens examined. ZoDION CINEREIVENTRE VaN DuZEE Zodion cinereiventris Van Duzee, 1927, Proc. Calif. Acad. Sci., 16:585 (California: Huntington Lake, Fresno County). This species is characterized by its small size: 4^2-5 mm., the dark abdomen of the male, and the open first posterior cell. This species is similar to abitus in the female and differs only in that the first posterior cell is always open. It is probable that this cell may be closed, showing variation similar to abitus, but in the East such individuals are referable to abitus and on the West Coast to triste. Females with rather wide first posterior cells have been seen from Michigan and New York, but may be considered extremes of abitus. Typical dark abdomened males have been examined from as far east as Illinois. Distribution: Western United States east definitely to Illinois. 34 specimens examined. Zodion triste Bigot Zodion triste Bigot, 1887, Ann. Soc. Ent. France (6)7:203 (Cali- fornia). ' This name is used here for a species in which the female genital plate is long, moderately wide, and thin in antero- posterior dimension ; and yellowish narrowly edged with the dark striations. The first posterior cell is closed or narrowly open. The length is 4^-5 mm., and it is otherwise similar to cinere- ventre. The males in which the first posterior cell is open cannot be distinguished from cinereiventre and would be referred here only when associated with the female.

Nat., 81 A., h.4, 97 (Cali- fornia) . Zodion hirtipes Van Duzee, 1927, Proc. Calif. Acad. Sci., 16:587 (California: Melrose, Alameda County). This species differs from the other members of the genus by the characteristic fourth vein, the last segment of which ends about halfway toward the wing margin. This character has proved constant in the twelve specimens examined and was mentioned in the original descriptions of both nigrifrons and hirtipes. The species in general has long hairs and is very dark, the front and antennae being usually almost entirely dark, and the thorax so dark that the darker dorsal lines may be quite indistinct. The palpi are short, about l]4x width of the proboscis, and not clavate. Length, 4]4-5 mm. Distribution: California (Melrose, Alameda County; Berke- ley; Fish Ranch, Berkeley Hills). 12 specimens examined. Zodion americanum Wiedemann Zodion americana Wiedemann, 1830, Auss. Zw. Ins., 2:242 (Monte- video) . Zodion nanellum Loew, 1869, Berl. Ent. Zeitschr., Cent. VIII, 75 (District of Columbia). Zodion pygmaeum Williston, 1885, Trans. Conn. Acad., 6:381 (Cal- ifornia) . "I Zodion occidensis Walker, 1849, List. Dipt. Brit. Mus., 3;676 (Ohio). This species is characterized by its small size: 3-5 mm., con- stantly open first posterior cell, and relatively sharply defined black markings of the thorax and abdomen. This species differs from cinereiventre and the other small forms in being covered with finer pollen which is bluish or green- ish; and in having the dark markings usually more extensive, more opaque, and more sharply defined. The variation in dark markings is very great and completely bridges the difference between nanellum and pygmeum. Three males from New Mexico (Highrolls, Alamogordo) completely lack the thoracic lines and spots, and have less black on the abdomen than usual. These may repreesnt another species. Nor- 126 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX, NO. 4 mally patterned specimens heve been examined from Highrolls. Krober has compared the type of americanum with nanellum and considers them the same species. I havie seen examples of this species from a number of localities in South and Central America. Distribution: Southern Canada, United States, Central Amer- ica, and South America. 226 specimens examined. ZODION PALP ALE RoBERTSON Zodion palpalis Robertson, 1901, Canad. Ent., 33:284 (Illinois: Carlinville) . This species is characterized by the black, long, clavate palpi; which are 2V^-3x the width of the proboscis at the level of the palpi. The first posterior cell usually has a long petiole, but it may be narrowly open. The labellae of the proboscis are quite long, about one-fourth the total length of the proboscis. They are much shorter in the previous species but apparently are long also in lovetti and parvum. When the labellae are together it may be difficult to decide their length. The abdomen of the male has the second and third segments yellow, more reddish on the distal part of the third; and is relatively long and slender. The legs are rather slender and entirely dark. Length, 5 mm. ; 1 $ 4 mm. Distribution: Illinois (Carlinville) and North Carolina (Raleigh). 19 specimens examined, including the type. Zodion scapulare Adams Zodion scapularis Adams, 1903, Kans, Univ. Sci. Bull., 2:34 (Ari- zona) . This species has not been seen by the writer, but has been in- corporated into the key. It represents a species between palpale and parvum, having the abdomen of the former and the palpi of the latter. Very few specimens are known of this group of species and additional material may show that some of these represent individual variation. Distribution: Arizona. Zodion parvum Adams Zodion parvis {parvus in key) Adams, 1903, Kans. Univ. Sci. Bull., 2:34 (Arizona). This species is characterized by its small size: 3% mm.; long petiole of the first posterior cell: 3x anterior cross- vein; short, OCT. 1944] CAMRAS— ZODION 127 pale, non-clavate palpi, lx width of proboscis; and dark ab- domen of the male. The legs are slender and dark, and the label- lae about one-third the length of the entire proboscis. Distribution: Arizona and Colorado (no locality). One speci- men examined. ZODION LOVETTI VaN DuZEE Zodion lovetti Van Duzee, 1934, Ann. Ent. Soc. Amer., 27:323 (Colorado: Fort Collins). This species is characterized by its long (2x width of pro- boscis), but not clavate palpi; entirely dark abdomen of the male; and small size: 4 mm. The first posterior cell is closed in the wing margin to petiolate as long as anterior cross-vein. The legs are slender and entirely dark. This species represents another link between pal pale and par- vum, having the long, though not clavate palpi of the former, and the dark abdomen of the latter. Distribution: Colorado (Fort Collins, Tennessee Pass). One specimen examined. The following species, each based on a single female, are not known to the author, and have not been included in the key: Zodion albifacies Van Duzee, 1927, Proc. Calif. Acad.

Pubescence: Pale throughout; long and dense on face, clypeus, cheeks, pleura, propodeum, and base of abdomen, front tarsi with a rather thin white fringe; segments 2-4 of abdomen with entire white apical fasciae, the fifth not fasciate but with some basal white tomentum, the sixth with dense white tomentum covering most of disc above. f Holotype female Douglas, Arizona, August 16, 1936 (W. W. Jones), allotype male, topotypical (W. W. Jones), [both Tim- berlake]. The male of suhparallela differs from that of parallela in the following respects: The definitely 3-dentate mandibles (either obscurely or distinctly 4-dentate in parallela) ; the absence of a median tubercule on the clypeal margin; the median apical teeth of the sixth tergum are truncate and carinate (usually slender and acute in parallela but subject to considerable varia- tion) ; the seventh tergum lacking the slight median indentation found in parallela’, and the lack of a distinct apical fascia on the fifth tergum. The range of variation in parallela is consid- erable, but this form seems to lie outside that range. The female of subparallela runs to sahinensis in the key re- cently published.^ However, sahinensis is much larger and the 3 1943, Pan-Pac. Ent., 19 :12. OCT. 1944] MITCHELL— MEGACHILE 135 clypeal margin is relatively straight, the median tubercle being minute and not delimited by the emarginations found in suh- parallela. Moreover, in sabinensis the scopa on the sixth sternum is entirely black, this being almost entirely pale in suhparallela, and the sixth tergum bears conspicuous white tomentum medi- ally, with darker erect basal hairs and appressed fuscous tomen- tum apically. In suhparallela the disc of this segment is quite uniformly covered with rather sparse suberect yellowish pubes- cence, with neither definitely black nor white hairs in evidence. Subgenus Delomegachile Viereck Megachile (Delomegachile) frigida Smith Before her death. Dr. Grace Sandhouse called my attention to the fact that I was in error in my use of the name vidua instead of frigida for this species. Smith proposed both names, vidua for the female on p. 192 and frigida for the male on p. 193 (Cat. Hym. Brit. Mus. 1, 1853). As the name vidua has page preced- ence, it was thought proper to use. HoweVer, Cresson in his Synopsis of Hymenoptera, p. 303, 1887, made vidua a synonym of frigida, in spite of the page precedence of vidua, and accord- ing to article 28 of the International Rules of Zoological No- menclature, “If the names are of the same date, that selected by the first reviser shall stand.” Subgenus Xeromegachile Mitchell Records of four species, namely deflexa^ manifesta, nevad- ensis, and wheeleri, are omitted in the following list, since they add little to the present knowledge of their distribution.

Subgenus Derotropis Mitchell Four species of Derotropis are known in both sexes, gravita ( 9 astata) , pascoensis ( 9 gabrielensis) , xerophila and astragali. Four other species are known only in one sex, the male only of alamosana and the females only of anograe, suhanograe'^' and laurita. It now seems probable that alamosana is the male of anograe, judging from the range, these being the easternmost in distribution, and from the similarity of the two forms to the respective sexes of gravita and pascoensis. This relationship, however, remains to be demonstrated. Some evidence concerning the identity of the male of subanograe can now be presented, but that of laurita still has to be discovered. Megachile (Derotropis) subanograe Mitchell A series of five females of this species received from C. D. Michener was accompanied by three males of M. {Xer omega- chile) maurata Mitchell, the two series bearing identical data as to locality, date and flower record. This suggests their common identity, and if proven correct, results in obscuring the distinc- tions between the males of Xeromegachile and Derotropis. They are quite similar in size and in general appearance, and to that degree the association seems a reasonable one. An additional question concerns the range of variation of the females of this species. A number of specimens from Arizona, California, Nevada, and Texas have been received, all bearing strong resemblances to typical subanograe, but with enough dif- ferences to indicate the possibility, at least, that they represent different species. Were these accompanied by males, a more * The specimen recorded on p. 174, Pan-Pacific Ent. 14, 1938, evidently is a. female, not a male as indicated. 140 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

XX, NO. 4 STUDIES AMONG THE COCCINELLIDAE— No. 9 (Coleoptera) BY F. W. NUNENMACHER Piedmont, California Zenora tricolor Nunenmacher, new species Light yellow, black and brick red. Head and pronotum yellow, with the exception of a faint trace of black in front of the scutellum where the black of the elytra overlaps. The simplest way to de- scribe the elytra is to say they are black with yellow margins and a brick red disc on the suture at about the center. The size of this disc is from about one-fourth the elytral length to beyond the mid- dle, and from not quite the center of each elytron. Unequal coarse punctures. The little remaining pubescence is white. Ventral sur- face, mouth parts, antennae, legs, sides and segments yellow, breast a little darker. Length 3 mm., width 2.25 mm. Holotype female, in the author’s collection, from Para Ama- zon, no other data. Crotch, Revision of the Coccinellidae, pp. 277-278, gives the following description: Z. revistita Muls. Var. E. Elytra metallic green, the margins from the shoulder to the apex pale ochrous but the disc pale. I do not think my species belongs to this group. Th. Dobzhansky, in Beetles of the Genus Hyperaspis Inhabit- ing the United States, 1941, says he cannot place the following three of my species: falli, floribunda and walcotti. I would like to make this clear to the students: falli is a true Hyperaspis’, floribunda and walcotti belong in Hyperaspidius. And to clear the note part of his statement, at that time I did not think that the genus Hyperaspidius would stand. The genus is principally based on the fova or depression of the epipleura which receives the knees of the hind pair of legs. I was then working on a lot of South American species of Hyperaspis and had noted that in many cases this fova is very shallow, and must be viewed in a very good, clear light to be seen. I still think it is a weak genus. The following three species of Hyperaspidius are undescribed, and I take this opportunity to make them known. OCT. 1944] NUNENMACHER— COCCINELLIDAE 145 Hyperaspidius juniperus Nunenmacher, new species Head straw yellow. Pronotum rufescent, margins and angles lighter. Elytra about as long as wide with tip slightly truncate, with a median and a common sutural black vitta. The median vitta somewhat broader than the light space at either side, starting at the callus and running parallel to the margin about five-sixths the length where it curves, becoming a narrow line which joins the sutural vitta. The sutural vitta at base a little wider than the scutellum, gradually widening, broadest at about one-third the leng-th, then narrowing to about two-thirds, from here remaining about the same width as at base to the tip of the elytra. Very finely punctured. Ventral surface and legs rufescent. Length 2 mm., width 1.25 mm.

Elytra longer than wide, tip slightly truncate; with a narrow yellow marginal band starting at the side of the scutellum to about the middle where it is interrupted for a short space, then it starts again just around the humeral angle along the margin not quite to two-thirds the length where it is a little broader; also a small spot at the tip, the same distance from the sutural margin and the tip of the elytron*, and a small elongate spot at two-thirds, about its own width from the suture and about twice as long as wide. Finely punctured, a little stronger than on pronotum. Ventral surface and legs black, anterior tibiae and tarsi pitchy. Length 2 mm., width 1.25 mm. Holotype female, in collection of author, from Oregon, July, 1938, with no other data. This pretty little specimen was kindly given to me by Dr. E. S. Ross some years ago. Hyperaspidius shauli Nunenmacher, new species Yellow and black. Head and pronotum rufescent, margins and angles lighter; females slightly darker than males. Elytra about as long as wide, tip not truncate. With a median and a common sutural black vitta. The median vitta starts at the callus and runs parallel to the margin to about five-sixths, where it curves and be- comes a narrow line joining the sutural vitta. In the male this vitta is only about half as broad as in the female. The sutural *I think a series of specimens will show this band and also the spot at the tip united to form a solid vitta. 146 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX, NO. 4 vitta starts at the base, just covering the scutellum, and is the same width to the tip. Very finely punctured. Ventral surface rufescent, the epipleura yellow. Length 2 mm., width 1.25 mm. Holotype male, allotype female and four paratypes, all from Perryton, Texas, August 13, 1937, collected by R. E. Shaul. Types and two paratypes in the author’s collection, one paratype female in J. E. Blum’s collection. This species is narrower, lighter in color, and the vitta are narrower than in oblongus Casey, as I remember his type. Coccinella ampla var. rufa Nunenmacher, new variety Coccinella ampla seems to be very variable even among those with complete maculations to albino forms. In July, 1937, A. R. Mead collected Coccinellidae in Mexico for me. Among his ma- terial I find seven specimens of this species collected in Oaxaca, Mexico, that are rufescent. The color and pattern of the prono- tum is fairly constant, with the exception of a yellow border, which in one or two specimens has a pale reddish color. The elytra are rufescent with a narrow pale margin. In the darkest colored specimens there is a trace of the black markings of the type form. This variety may take the name rufa Nunemacher, n. var. Types and five paratypes remain in the author’s collection. AN ABERRANT SPECIMEN OF AGLAIS ANTIOPA (LINN.) On September 3, 1944, while collecting in the open forest- land near the Donner Summit Inn, at an altitude of approxi- mately 7,000 feet an aberrant specimen of Aglais antiopa was seen. The specimen was observed closely, although it subse- quently evaded capture and disappeared. It was undoubtedly of the type which has been named hygiaea Heydenr., as all other named aberrations of this species vary in other respects than the great widening of the yellow border and loss of the sub- marginal band of purple spots. In this specimen the yellow border was greatly broadened and diffused inwardly, occupying at least one-third of the width of the wing. In this respect it equalled, or perhaps even surpassed the width in the specimen figured by J. A. Comstock in Butterflies of California, Plate 42, figs. 3 and 5. Only a slight darkening apparently remained of the submarginal band of spots. — R. W. L. Potts and R. F. Smith. OCT. 1944] VAN DYKE— OSTOMIDAE 147 NEW SPECIES OF NORTH AMERICAN OSTOMIDAE (Coleoptera) BY EDWIN C. VAN DYKE Calif of-nia Academy of. Sciences, San Francisco In 1915, I published in the Bulletin of the Brooklyn Ento- mological Society, descriptions of a number of new species of the genera N emozoma and Corticotomus and gave a short review of the known species found north of Mexico. In 1916, in the same journal, I described another N emozoma, the name of which had to be modified later because it was found to have been previ- ously used in the same genus. In 1918, in the Journal of the New York Entomological Society, Schaeffer contributed an arti- cle in which he described new species in both N emozoma and Corticotomus while in 1916, Casey described in his Memoirs, a closely related genus and made certain remarks concerning Corti- cotomus. Recently, other undescribed species of both N emozoma and Corticotomus as well as a related species which will have to have a new genus erected for it, have come into my hands. These recent additions I will now describe and inasmuch as there is still considerable confusion concerning previously described spe- cies and some new information, make revised synopses of the two genera. Nemozoma cupressi Van Dyke, new species Elongate, about five times as long as broad, cylindrical, moder- ately shining, black with a rufous patch covering a little more than a fourth of the base of the elytra yet not reaching the lateral margins, and the three segments of the antennal club also' some- what rufous. Head about one-eighth longer than broad, deeply sulcate anteriorly and with an acute angular emargination in front with the apices of its lateral boundaries slightly everted, with distinct and well spaced punctures and a linear groove at the bot- tom of the sulcus and at the base of the head in line with it; antennae 11 — segmented, reaching the base of head, segments 2-8 small, 3-8 gradually broader and as a whole subequal in length to the club the first two segments of which are almost three times as broad as the eighth segment; eyes moderately large but much flat- tened as seen from above as they hardly project beyond the side margin of the head. Prothorax equal to the head in length, nar- rower at base than elytra, gradually broader toward apex where about equal in breadth to head and elytra, disk convex, with punc- 148 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

Elytra about twice as long as broad, sparsely, finely and irregularly punc- tured except near base and suture where arranged in rows, the general surface also less shining than head and pronotum, and the apex with the sutural striae well impressed. Beneath rather finely and sparsely punctured on head and entire thorax and still more finely punctured on abodmen. Length, 6.5 mm.; breadth, 2 mm. Holotype (No. 5426, Mus. Calif. Acad. Sci., Ent.) and one paratype^ the latter 7.5 mm. in length, both beaten from Sargent cypress at Occidental, Sonoma County, California, August 1, 1939, by Arthur T. McClay. The paratype is in the collection of Mr. McClay. This species is in general a bit larger than N. fissiceps (Fall), our largest species hitherto described and somewhat similar ex- cept that the latter has the pronotum an orange red and the legs as well as base of elytra reddish, and elytral punctures more regularly arranged. N. attenuatum Van Dyke is smaller and much narrower, more attenuated, has somewhat rufous legs as well as 10 segmented antennae; N. punctulata Van Dyke is simi- larly colored, smaller, has the orange patch at base of elytra more extensive and the elytral punctures more regular; while N. schwarzi Schaeffer is very much smaller, has shorter elytra and orange patches near apices of elytra as well as near the base. Nemozoma fenyesi Van Dyke, new species Elongate, not quite five times as long as broad, cylindrical, mod- erately shining, head, pronotum and narrow basal area of elytra black, the greater portion of elytra a bright red, and the antennal club, legs and entire under surface more or less rufous. Head almost as broad as long, deeply sulcate anteriorly as usual but with the frontal margin feebly trisinuate, almost transverse, the median portion narrowly and feebly emarginate, not deeply and angularly cleft as in our Pacific Coast species, with distinct and well spaced punctures and the median linear groove not apparent in the sulcus nor at the base of the head; the antennae 11 — seg- mented, reaching the base of the head, with segments 2-8 small, as a whole subsqual in length to the club, the club three-segmented as usual and very distinctly unilaterally dilated; the eyes moder- ately large but flattened as in the preceding species. Prothorax equal to the head in length, just perceptibly narrower at base, the sides straight and parallel, disk convex, with punctures similar to those of head but finer and denser, side and basal margins fine but distinct. Elytra more than two and a half timesi as long as broad, striate, the sutural stria well impressed and complete, the discal distinct but the lateral lacking, the strial punctures fine and close together OCT. 1944] VAN DYKE— OSTOMIDAE 149 medially, less regular laterally. Beneath rather finely and sparsely punctured. Length, 7 mm.; breadth, 1.75 mm. Holotype (No. 5427, Mus. Calif. Acad. Sci., Ent.), a unique from the Fenyes’ collection of the California Academy of Sci- ences, collected by Dr. Fenyes at Cordoba, Mexico. This species is very distinct from any of our species, by its color pattern and physical characters, particularly the modifica- tions at the front of the head, and the distinct elytral striation, and from the Guatemalan species, signatum Sharp, by the color pattern. Dr. Sharp did not clearly describe the peculiarities of the head in his species but from the illustration given in the “Biologia,” I am inclined to believe that fenyesi and signatum have the front of the head quite similar.

Br. Col., Or. and northeastern California, on pines. 4. 5-5. 5 mm punctulata Van Dyke 150 THE PAN-PACIFIC ENTOMOLOGIST [VOL. XX, NO. 4 As indicated in the table, attenuatum is the only species in our fauna which agrees with the European elongatum L,, the type of the genus Nemozoma of Latreille, in having ten-segmented antennae. Its geographical position is also significant in this connection for it is strictly a member of the Vancouveran insect fauna, the fauna which has in many ways a close relationship to the Eurasian fauna. All our other species have eleven-seg- mented antennae and hence fall into Monesoma of Leveille which is generally considered, and I think correctly so, to be but a subgenus of Nemozoma. The bulk of the species in the subgenus are confined to the New World: western North Amer- ica, Mexico, Central and South America. Our Pacific Coast spe- cies are somewhat similar in having the head very deeply sulcate in front and angularly divergent apically, also with a somewhat similar color pattern. Our Arizona species, schwarzi, is some- what different in that it has the head narrowly grooved in front, the elytra short and quadrimaculate. The Mexican species, fenyesi, which I have described above, differs from all the species found north of it in not having the apex of the head distinctly and triangularly notched but by being almost transverse. The Guatemalan species, signatum, I believe also approaches it in this regard. Genus Corticotomus Sharp The members of this genus superficially resemble those of Nemozoma and have quite similar habits, also often have similar color patterns. They differ by having the head flattened above or even somewhat concave, with the mandibles directed upward, not downward as in N emozoma, and as discovered by Casey, have the elytra with a perforate foramen within the humeri. It is entirely a New World genus, found in both North and South America. In the Leng Catalogue, the species are correctly placed but in the Coleopterorum Catalogus, they are placed partly in N emozoma and partly in Corticotomus. The genus Parafilumis Casey with the single species, estriata Casey, is very closely re- lated to Corticotomus and apparently only differing from cali- fornicus Van Dyke by having the elytra diffusely punctured, not with the punctures more or less regularly arranged in rows. Three of the species of Corticotomus are found on the Pacific Coast, three on the Atlantic Coast, with one subspecies in south- ern Texas. Parafilumis is from Oregon. OCT. 1944] VAN DYKE— OSTOMIDAE 151 Corticotomus apicalis Van Dyke, new species Small, elongate, about four times as long as broad, moderately con- vex above, more or less flattened as seen from the side, shining black, with antennae, palpi, legs and disk of elytra anteriorly testaceous. Head almost as broad as long, depressed in front and with a feeble yet distinct triangular excavation, apical margin transverse, man- dibles prominent and feebly upturned, punctures well impressed and dense in frontal impression, more sparse at base and some- what aciculate at sides; antennae 11-segmented, reaching several segments behind base of head, segments 2-8 small, gradually broader outwardly, club well developed, distinctly unilaterally dilated, segments 9-10 triangular and eleventh elliptical; eyes of fair size and feebly convex and projecting from the side of head as seen from above. Prothorax somewhat longer than head, rounded at base and with sides straight and parallel, side and basal mar- gins fine but distinct, punctures rather evenly placed and well spaced. Elytra testaceous over three-fourths of area anteriorly and piceous at apex, the dark area extending forward along suture and sides, about one^fourth longer than head and prothorax to- gether, at least twice as long as broad, feebly striate at sides of disk, more obscurely so toward suture and side margin, punctures fine and close in striae, more vague where striae, poorly defined, intervals flat and with a series of fine punctures, generally close to the strial punctures giving at times the appearance of double striation, and a perforate foramen within the humeri. Beneath finely, sparsely punctured in front, abdomen quite smooth. Length, 3.5 mm.; breadth, 1 mm. Holotype (No. 5428, Mus. Calif. Acad. Sci., Ent.), from Mt. Wilson, California, August 5, 1924, in the Blaisdell collection of the California Academy of Sciences, and two paratypes; An- derson’s Valley, California, March 12, 1914, from Sugar pine and Mt. St. Helena, California, March 29, 1931, collected by myself from the burrows of Cryphalus in Douglas fir. The para- types have the elytral striae less marked than they are in the type. The specimens mentioned above, I have had set aside for sometime, considering that they perhaps belonged to a pygmy race of caviceps. Upon more critically reexamining them, how- ever, I find characters which set them aside from that species. It is not only smaller, but proportionately narrower, more shin- ing, the prothorax longer than broad, about as broad as long in caviceps, and with finer and less dense punctuation. The elytra have a different color pattern and are less convex, in fact the entire insect is more depressed, with a dorsoventral measurement much less than in the other. 152 THE PAN-PACIFIC ENTOMOLOGIST [VOL.

Muir has stated that consohrina and ustulata Stal are not typical tentatively leaving forty-nine spe- cies with discrepans provisionally included in Pintalia. Un- doubtedly intensive collecting will more than double the number of known species. Unless stated otherwise all types are in the author’s collection. Pintalia dorsovittata Van Duzee (figs. 1, la) If I interpret this species correctly it has been confused with delicata Fowler. In a series of twenty specimens from Florida, South Carolina, Tennessee, and Virginia the elytra are not always unicolorous with the distinct dorsal stripe. The intensity of color has a wide range and most of the specimens have a more or less mottled elytra. Aspersa Dozier^® from Mississippi either belongs to this species or is new.

Pint ALIA aspersa Fowler (Figs. 12, 12a) This is a short and compact species with the lateral carinae of the frons wide and flattened. This latter character is similar to discrepans Muir which Muir only provisionally places in this genus. Likewise Fowler believed that aspersa may not belong in Pintalia. However, from the species and specimens before me this character appears to be gradational with several species ex- hibiting carinae with varying degrees of flatness making it im- possible to draw any definite line between the two groups. Most of the specimens with flattened carinae have the radius usually four-branched but this is not consistent. Most of the specimens before me are darker than the illustrations in the Biologia (pi. 9, fig. 24) with the mid-dorsal stripe less pronounced. The size ranges between 5 and 6.4 mm. with several females as well as males only 5 mm. The most spines visible on the hind tibiae are four with three being more common. The lateral margins of the male pygofers have a rather long, acute projection caudad and well dorsad; medio-ventral process is very small. Specimens from Oaxaca, San Luis Potosi, and Vera Cruz in Mexico, and two from Guatemala. Pintalia neoaspersa Caldwell, new species (figs. 13, 13a) Length, 6-6.5 mm. Color and marking identical to aspersa, the elytra with possibly more solid colors. Upper third of lateral carinae of frons similar to that species. Lateral margins of male pygofers truncate, straight; medio- ventral process small, triangular. Styles sharply excavate on inner third of basal margins. Apex of anal segment slender. Aedeagus with coarsely serrated spur on right side of apical portion; peri- andrium serrate around joint of aedeagus.

XX, NO. 4 Holotype male, and paratype male, Esmeralda, Chiapas, Mexico, November 18, 1930, male paratypes Santa Isabel, Chiapas, Mexico, November 17, 1930, allotype female, and five female paratypes Santa Isabel, Chiapas, November 17, 1930 (Dampf), and one male paratype Jesus Carranza, Vera Cruz, Mexico, Oct. 14, 1941 (De Long, Good, Caldwell & Plummer). Pintalia acarinata Caldwell, new species (figs. 14, 14a) Length, 6 mm. Head and thorax concolorous with lateral com- partments of mesonotum darker. Elytra clear to clouded with brown; a definite white spot present at union of claval veins; another extending from apex of clavus almost to apex of elytra; area around stigma clear; a definite fuscous stripe originates at fork of medius and projects toward apex of costal margin, this stripe is sometimes broadened to include the entire apex of the elytra in which case the fuscous is broken by white areas. Apical terminations of veins thickened, white. Carinae of face similar to aspersa. Male styles with inner margins deeply excavate in basal fourth, contiguous in next fourth, divergent in next fourth, and parallel in apical fourth. Anal segment relatively short. Holotype male, and two paratypes from B. Esperanza, Guate- mala, December 15, 1925 (Dampf). This species and neoaspersa can be separated from aspersa by their much more slender appearance, greater length, and distinct male genitalia. D. B. MACKIE PERPETUAL MEMORIAL LOAN FUND The California Entomology Club is sponsoring the establish- ment of a D. B. Mackie Perpetual Memorial Loan Fund for the benefit of graduate students in Entomology at the University of California. The immediate goal is $1,000.00 of which more than $750.00 has already been subscribed. Mr. Mackie’s entomological work is an especially suitable memorial for such a fund since he so greatly benefited California Agriculture through his pioneer work in vacuum fumigation, both with cyanide and methyl bro- mide. Contributions may be sent to H. H. Keifer, Secretary- Treasurer, California Entomology Club, State Office Building No. 1, Sacramento, California. OCT. 1944] INDEX TO VOLUME XX* 161 Acarina, 7.
