FALL Issued November //, 1901 SAN FRANCISCO CALIFORNIA ACADEMY OF SCIENCES 1901 LIST OF THE COLEOPTERA OF SOUTHERN CALI- FORNIA, WITH NOTES ON HABITS AND DISTRIBUTION AND DESCRIPTIONS OF NEW SPECIES. BY H. C. FALL. INTRODUCTION. THE Coleoptera of California, or of any considerable part thereof, have never been made the subject of exclu- sive treatment by any of our entomologists. Portions of the State have, it is true, formed a part of much more ex- tensive areas treated in some of the earlier faunal papers of Le Conte, but in none of importance have the Califor- nian species been so numerous as to constitute a majority of those listed. Of these papers, two are especially worthy of mention, viz: The Report on the Insects col- lected on the Pacific R. R. Survey adjacent to the 47th parallel (1857), and the Catalogue of the Coleoptera of the Region adjacent to the Mexican boundary line (1858). In the former, 1,173 species are listed from Northern California, Oregon, Washington, and Alaska, of which 520 are Califomian; in the latter, of about 1,000 species mentioned, 300 are credited to Southern California. To both of these, short supplements were added in 1858 and 1859. In an earlier paper (1851), Le Conte had published descriptions of 335 species from various parts of California, all of which are incorporated in the two lists above mentioned. [ l ] December 29, 1900. 2 CALIFORNIA ACADEMY OF SCIENCES. Previous to the time of Le Conte our knowledge of the Coleoptera of the Pacific Coast was due entirely to the writings of Eschscholtz (1829) and Mannerheim (1843- 1853). Both of these authors confined their attention to the fauna of the northern coast region — more especially of Alaska — and, as is remarked by Le Conte, at the close of Mannerheim's labors, the fauna of that region was more completely developed than that of any other part of the continent. In 1859 Le Conte published a list of 147 species col- lected by Xantus at Fort Tejon. The number is insig- nificant, but the list is interesting in the present connection, since Fort Tejon lies at the southern end of the San Joaquin Valley, on the northern slope of the mountains which separate the valley from Southern Cal- ifornia. Of the 147 species named, 120 are now known to occur south of the mountains. From 1859 to 1876 several papers of a faunal nature were contributed by Le Conte, Horn, and Ulke, none of which, however, are so important as to require special mention. In these, as in the two first named, the refer- ences to Californian species are for the most part con- tained in lists covering a much wider territory. Since 1876 only a few local lists have appeared, the most important being that contained in the report of the Death Valley Expedition;* the Tenebrionidse, Cicindelidse, Histeridae, and Coccinellidse observed in San Diego County by Dr. F. E. Blaisdellf and two lists presented by the author, one of a collection made in the San Bernardino Mts.,J and the other of the Coleoptera known from the Southern California islands.;/ * North American Fauna, No. 7, 1893.

It were desirable for many reasons that the scope of the present work be enlarged to cover the fauna of the entire State. I do 'not, however, at present feel suffi- ciently familiar with the northern fauna to warrant so great an undertaking. Indeed, I have many times been tempted to indefinitely postpone the present paper, because of the very meager knowledge which we possess of the great majority of even the commoner species of our district. With a view to completeness, however, and in order to increase the usefulness of the present list, I have in the " Notes " added at the end of each genus the names — nearly always with localities, but usually without further comment — of all other species known to have occurred within the State. It is not unlikely that a certain number of these, recorded by the older writers simply from "California," may have been found within the limits of Southern California; but I have very rarely ventured to include a name in the list without definite knowledge of its occurrence within the limits of the territory here treated. Briefly described, the term Southern California, as here used, includes that part of the State lying to the south and east of a line drawn from Point Conception eastward along the Santa Inez Mountains, then curving to the north and east around the southern end of the San Joaquin Valley, and along the desert slopes of the Sierra Nevada Mountains through Kern and Inyo counties, to the Nevada state line. The region thus defined is by no means a distinct zoological district, but its northern boundary line is as nearly an interfaunal one as it is possible to draw across the State. Its area is approximately one-third that of the entire State, and includes San Diego, Riverside, San Bernardino, Orange, Los Angeles, and Ventura counties; the southern part 4 CALIFORNIA ACADEMY OF SCIENCES. of Santa Barbara, the eastern part of Kern, and the greater portion of Inyo counties. To the student who is unacquainted with the topog- raphy and climatic conditions of California, the follow- ing brief sketch of the natural features, more especially of the region under consideration, will be of service. The State lies approximately between the parallels of 33° and 42° of latitude, and is crossed by two great mountain systems, lying along and in general parallel with its eastern and western borders. The former — the Sierra Nevada — extends from near the northern border to about the 35th parallel. Its average eleva- tion is from 5,000 to 8,000 feet, but there are occasional ridges of 9,000 and 10,000 feet altitude, and individual peaks that exceed 14,000 feet. The eastern slope descends quite abruptly to the Great Basin, itself 4,000 to 5,000 feet above the sea level; the western slope is much more gradual. The Coast Range consists, like the Sierra Nevada, of numerous nearly parallel ridges, and extends the entire length of the State. Its general altitude is from 2,000 to 6,000 feet. These two systems are united near Mt. Shasta in the north by a series of cross ranges, and again in the south near the northern boundary of Los Angeles County, thus inclosing the great central valley, some 400 miles long and 60 miles wide, drained by the Sacramento and San Joaquin rivers, which, after their junction, find their way to the ocean through a gap in the Coast Range at the Golden Gate. South of this junction of the Sierra Nevada and Coast Range, the two systems are continued as a single one, running in a generally southeasterly direction toward the Colorado River, sending off, however, at about the middle of its length, a branch to the south, known as the San Jacinto- COLEOPTERA OF SOUTHERN CALIFORNIA. 5 Range. The principal chain, extending from the Tejon to the Colorado River, has received various local names, the central and highest portion being known as the San Bernardino Mountains. Taken as a whole, it is for convenience frequently referred to in the following pages as the Southern Sierras. To the east of these mountains lie the Colorado and Mojave deserts, while to the west the country is broken, especially toward the coast, by numerous short ranges of no great altitude, between which lie fertile valleys. The climate of Southern California varies much according to locality, but it is in general mild and dry. Along the coast the mean temperatures of January and July differ by but little more than 10°, but toward the interior the difference between summer and winter tem- perature becomes rapidly more marked. Except in the higher parts of the mountains, the mercury rarely drops below 28° Fahrenheit in winter, but not infrequently rises to or even exceeds 100° in the summer months in the interior valleys. The summers in the desert region of the southeast are excessively hot, a temperature of 130° being at times experienced at Yuma and other points along the lower Colorado River. In all parts of our territory the year is divided into two well defined seasons, a rainy and a dry. The for- mer usually begins toward the end of October and lasts till April. During this season the fair days greatly out- number the rainy ones, and the precipitation is on the average less than that during any period of equal length on the Atlantic slope. The average rainfall at Yuma is less than 4 inches; at San Diego 10 inches; at Los Angeles 20 inches, and becomes somewhat greater as we ascend the western slopes of the mountains. Snow falls every winter at altitudes of 3,000 feet and over, but 6 CALIFORNIA ACADEMY OF SCIENCES. lasts only a short time, except on the highest peaks, where, in sheltered spots on northern slopes, it may be seen in midsummer. At intervals of many years the ground is whitened for a few hours in the valleys. The locally diverse conditions of temperature and rainfall are of necessity accompanied by a variation in the character and abundance of the vegetation, and consequently of the insect fauna. Only along the crests or upper slopes of the higher ranges — notably of the San Bernardino Mountains — is there anything approaching forest growth. At these altitudes — 5,000- 8,000 feet — there are considerable areas covered sparsely with pine, cedar, fir, and scattered oaks. Alders line the streams in the mountain canons, while willows, sycamores and cottonwoods grow along the water courses at lower levels wherever the supply of moisture is suffi- ciently permanent. Oaks of several species are more or less common throughout the lower foothills, and occur here and there in park-like groves in the valleys. The foothills are everywhere covered with a mixed growth of scrub-oak, Ceanothus, greasewood, manzanita, and a variety of other bushes and low trees, which, in some places, form almost impenetrable thickets. The valleys are green in the rainy season and in early spring are bright with a profusion of wild flowers, but are burned dry and brown by the sun in summer and autumn. The vegetation of the Colorado and Mojave deserts is naturally limited in amount and peculiar in kind, con- sisting mainly of Yucca, cactus, and mesquite, with the usual "sagebrush". From the preceding remarks it may be seen at once that Southern California is separable into two principal faunal districts — one the desert region to the eastward, occupying more than half the entire area and extending COLEOPTERA OF SOUTHERN CALIFORNIA. 7 far to the north and east beyond the State line; the other, the more copiously watered country lying between the principal mountain range and the coast. To these two we may add two others of very limited area, but quite as well denned, viz, the timber belt of the higher ranges; and the beaches, salt flats, and sand dunes immediately adjoining the seashore. While it is true that a large proportion of the species occurring in each of these districts is to be found in none of the others, yet our acquaintance with many parts of the territory here considered is still too imper- fect to permit the expression of these facts in figures. In the preparation of the following list I have care- fully searched all the literature at my command, and I believe that omissions of this sort will not be numer- ous; there doubtless are, however, a considerable num- ber of species in collections, which are not here included, for the simple reason that they have not been recorded. Of such as these, and of omissions or cor- rections of any kind, I would be very glad to be notified in order that they may be incorporated in any revision or supplement which may appear in the future. Notwithstanding the inevitable shortcomings incident to any preliminary list — and this can scarcely claim to be more — the number of species here credited to South- ern California is larger than that of any other faunal list yet published in North America.* The Southern California list proper contains 2,197 species and 17 varieties, and to these may be added 1,220 species and 4 varieties from other parts of the State, to which refer- ence is made in the notes, making a total of 3,417 species and 21 varieties for the entire State. * A catalogue of the insects of New Jersey by John B. Smith has appeared since the above was written and contains the names of 2,845 species of Coleoptera- a number greater than that here recorded for Southern California, but considerably smaller than that here credited to the whole State. 8 CALIFORNIA ACADEMY OF SCIENCES. Following the notes on distribution, etc., there will be found descriptions of a considerable number of the new species mentioned in the list. There are still many others left undescribed, chiefly for the reason that their proper definition would require a more extended investigation than is now possible. A few allied spe- cies from other parts of the country have also been described. Finally, it is a pleasure to acknowledge the kind and ready assistance of entomological friends in the prepa- ration of the following pages, more particularly of my fellow Californians, Messrs. Fenyes, Daggett, Fuchs, Van Dyke, Rivers and Ricksecker. To Mr. Fuchs I am especially indebted for a careful examination of the manuscript and the consequent detection of a few errors and the addition of a number of species based upon his own collection.

Cal." by Horn ("The Coleoptera of Baja California ")* without definite locality; it was described from the Gila River, and should occur along the Colorado; in the type the sutural stria is very feeble, but I suspect that this may be merely an individual variation. *Proc. Cal. Acad. Sci., 2nd Ser., Vol. IV, 1894, p. 313. COLEOPTERA OF SOUTHERN CALIFORNIA. 53 Hygrotus. — H. hydropicus, rather rare, Pomona and San Diego. Ccelambus. — C. medialis, rather common everywhere: fraternus, Colorado River: pedalis, not common, River- side and Pomona, May and June: lutescens is quite com- mon in middle California, — San Francisco, San Jose, Sacramento: impressopunctatus , one specimen, Lake Tahoe (Fenyes). Deronectes. — D. griseostriatus, not common, Redondo, December and February: striatellus, exceedingly abun- dant everywhere. Hydroporus. — H. addendus, rare at Pomona and Ojai Valley, more common a little further north: fortis, rare, San Diego; subpubescens, not common, though widely diffused: axillaris, southeastern region, probably Yuma: vilis and latebrosus, common in most localities. The following species are also reported from the State and some may possibly occur within our limits, though the species of the genus are as a rule more northern in habitat: eximius, rivalis (=sanmarlci Sahib, according to Fauvel), terminalis and hardyi. Mr. Fuchs has a record of H. funereus from San Diego. This is quite likely correct, but needs verification. Coptotomus. — C. interrogatus is common at Needles in August (Wickharn). Hydrotrupes. — H. palpalis is one of our rarest species, occurring in the mountain streams of the southern Sierras. Ilybiosoma. — /. regularis is plentiful everywhere. Agabinus. — A. glabrellus, rather scarce as a rule, but once found in some numbers in a small spring on Cata- lina Island. Agabus. — A. lugens, abundant everywhere- lineellus, very rare, Pomona, April and May: morosus, Pomona, 54 CALIFORNIA ACADEMY OF SCIENCES. San Diego; not common: obsoletus, San Diego (Le Conte); lecontei, rather common, various localities. The follow- ing species are found farther north: inter sectvs, brevicol- lis, confertus, strigulosiis, tristis (Lake Tahoe), xuturalis, erichsoni. Rhantus. — R. bmotatus, common generally: anisony- chus, much rarer, Pomona: jtavogriseus and sinuatus are reported from the State, but I have not seen specimens from the south. Colymbetes. — C. strigatus, rare; a single specimen taken at San Bernardino in April: sculptilis is recorded from the State by Crotch: seminiger occurs in the north- east. Eretes. — E. sticticus is a cosmopolitan species which has occurred once at Soldiers' Home (Van Dyke). Hydaticus. — H. ntagnalis is recorded from "Cal." (Horn, " The Coleoptera of Baja California"*). Dytiscus. — D. marginicotti8,8C&YCQ; several specimens taken by Mr. Daggett in Bear Valley, elevation 7,000 feet, June; one example taken by myself at Santa Monica. Thermonectes. — T. basilaris var. intennedius, one example, Pomona, September: marmoratus, near San Diego (Fuchs). Cybister. — 0. explanatus, not rare, many localities: ellipticusy Colorado River. Both species are frequently attracted by electric lights. GYRINID^. This family is very poorly represented in Southern California. *Proc. Cal. Acad. Sci., 2nd Ser., Vol. IV, 1894, p. 314. COLEOPTERA OF SOUTHERN CALIFORNIA. 55 Gyrinus. — G. plicifer occurs in the small streams of the mountains and foot-hills, while consobrinus gene rally prefers larger and more permanent waters; the former is not rare about San Francisco, more especially in the small streams of the redwood region, a few miles north of the Bay; the latter extends its range into Oregon. I have seen hundreds of consobrinus about the electric lights at Riverside, in May. Le Conte mentions having two examples of affinis from middle California, and I have a species of doubtful identity from the middle Sierras. Gyretes. — G. sinuatus, occurs at Yuma (Le Conte). HYDROPHILID.E. Helophorus. — H. obscurus, common and widely dif- fused: species doubtful, one example, Ventura, March: fortis, San Francisco (Le Conte): angustulus, northern. Hydrochus. — Uudescribed species, Ojai Valley, March; San Bernardino Mountains, July; rare: variolatus, San Diego (Le Conte): vagus, Colorado River. Ochthebius. — The species occur sometimes in great numbers in the mud or silt or under stones in the shal- low water of the margins of streams or pools, where any agitation of the bottom brings them to the surface, upon which they float and are easily taken. 0. rectus is our commonest species and occurs nearly everywhere; I have taken it plentifully in muddy irrigating ditches at Riverside, in clear streams, and at San Diego on a salt marsh which is covered by tide- water: interruptus, Riverside, San Diego, Redondo; common at the latter place, living in algse in a small lake much salter than the ocean: discretus, widely diffused and moderately common: puncticollis, rare, San Bernardino Mountains, Ojai Valley: sculptus, rare, Ventura: costipennis, one 56 CALIFORNIA ACADEMY OF SCIENCES. example, Ventura, March: holmbergi, Santa Monica and San Diego, not very common: lineatus, abundant at Yuma, July: nitidus, Yuma (Le Conte). Dr. Horn records Icevipennis from Fort Tejon, and I have taken cribricollis at San Francisco and Lake Tahoe. Hydraena. — H. pennsylvanica, common everywhere in same situations as Ochthebius. Hydrophilus. — H. triangularis, not rare, comes quite often to electric lights: insularis, said by Horn ("The Coleoptera of Baja California ")* to occur in Southern California. Tropisternus. — All the species common and generally distributed except salsamentus, which has occurred only in the Redondo salt lake, April to June, and in salt pools at Santa Barbara, August. Hydrocharis. — H. glaucus, three examples taken by Mr. F. D. Twogood in a watering trough at a lumber camp in the San Bernardino Mountains, elevation 5,000 feet, September; found also on Santa Cruz and Santa Rosa islands, but everywhere rare; and by Dr. Blaisdell in Calaveras Mountains, Mokelumne Hill and on Mt. Diablo (Fuchs): obtusatus, one example in mountains near Pomona, elevation 4,000 feet, August: rickseckeri occurs near Santa Rosa (Ricksecker). Berosus. — B. punctatissimus, not rare, Pomona to San Diego: miles, plentiful at Yuma: subsiynatus , Colorado River: salinus, Redondo salt lake, not rare in early spring; found also in salt pools at Santa Barbara in Au- gust: infuscatus, Yuma, San Diego, Redondo, Pomona, etc., rather common: rugulosus, very rare, only two examples found, Pomona, June and September. Chsetarthria. — All three species are found about equally common by washing the sandy margins of streams. *Proc. Gal. Acad. Sci., 2nd Ser., Vol. IV, 18H p. 315. COLEOPTERA OF SOUTHERN CALIFORNIA. 57 Limnebius. — L.piceus, common enough when found, but inclined to be local; I have found it in numbers in the streams of the foot-hills near Pomona and Pasadena; jwl'itus, alutaceus and congener are names given by Casey to forms occurring from San Francisco north; they are, I think, based merely on local or individual and sexual variations of piceus. Laccobius. — L. ellipticus is extremely abundant every- where. Philhydrus. — P. carinatus and P. nebulosus are com- mon and widely diffused: diffusus, not rare in the Redondo salt lake, also in salt marsh at Santa Barbara: cuspidatus and hamiltoni are recorded from the northern part of the State. Specimens taken by myself at Sacramento are by their color to be referred to hamiltoni ; this differ- ence, however, is of little consequence, and they are structurally not materially different from diffusus of Southern California. P. californicus is from an unre- corded part of the State/ 'probably northern": conjunctus occurs at Lake Tahoe. Helochares. — If. normatus is found in most localities, but nowhere very common. Cymbiodyta. — C. punctatostriata, found only in moun- tain streams: dorsalis, common and generally distrib- uted: imbellis occurs from Fort Tejon north, and is not rare in the neighborhood of San Francisco. Hydrobius. — H. fuscipes, not common, Pomona, Riv- erside, San Bernardino: lotus t extreme north: scabrosus, San Francisco and north. Creniphilus. — C. subcupreus, not very frequent; Po- mona, San Bernardino Mountains, Yuma: elegans* not common, in the salt lake at Redondo: rujiventris, rare at * Specimens of this species recently received from Mr. Schwarz were taken by the late Henry G. Hubbard in salt springs at Salton on the Colorado Desert. 58 CALIFORNIA ACADEMY OF SCIENCES. low altitudes, but more plentiful in the higher parts of the Sierras: infuscatus, common: dissimilis, San Fran- cisco and north. Dactylosternum. — D. cacti, one example, Los Angeles County (Van Dyke); occurs abundantly in decomposing cactus (Cereus) in Arizona, but is thus far rare in Southern California. Cercyon. — 0. fimbriatus, everywhere abundant along the seashore in decomposing seaweed: luniger, much less frequent in same situations, and on Catalina Island, where fimbriatus has not yet been found: fulvipennis, common in excrementitious matter: lugubris, not rare, about the roots of grass in marshy places, and in decay- ing vegetable matter: nigriceps, rare, San Diego, Pomona. C. depressus, quisquilius, lateralis, tristis and navicu- laris are quoted from California in Horn's Revision. Megasternum — M. posticatum, rather common in de- composing vegetable matter, especially along the moun- tain streams. SILPHID.E. Necrophorus. — N. marginatus, rare; one specimen taken at Riverside, June: guttula, numerous on San Clemeute Island, May and June, rather scarce on the mainland: puztulatns var. nigritus, not rare on both islands and mainland; numerous specimens taken in electric light trap at Pasadena, April and May; var. melsheimeri is northern. Silpha. — 8. lapponica and S. ramosa are generally common: opaca, one specimen mentioned by Dr. Horn as taken near Mono Lake. Necrophilus. — N. hydrophiloides , from middle and northern part of State. COLEOPTERA OF SOUTHERN CALIFORNIA. 59 Agyrtes. — One example of longulus taken at Pomona under live-oak chips, February 15, 1896 ; one example also taken by Dr. Fenyes at Pasadena, January, 1898. Sphserites. — 8. glabratus is northern. Pinodytes. — One dead and mutilated specimen of cryptophagoides (?) found with ants at Pasadena (Fenyes). Platycholeus. — Several specimens of leptinoides were taken by me in very rotten wood at Lake Tahoe, July; the species is termitophilous (Koebele, Hubbard, Fenyes). Choleva. — C. basillaris from middle and northern part of State. Ptomaphagus. — P. consobrinus, Pomona, San Bernar- dino Mountains, uncommon; one specimen found at Pomona with ants in March: calif ornicus, "San Diego northward" (Horn): pusio, northern: fisus, Owens Valley. Colon. — C. clavatum and G. inerme are both northern. Triarthron. — T. lecontei, "high Sierras east of Visalia." Hydnobius. — H. latidens, one example, so referred by Dr. Horn, Ojai Valley, March: longulus, northern. Anisotoma. — Specimens of this and the preceding genus are rare, and are most often taken on the wing an hour or two before sunset on warm days in early spring: paludicola has thus occurred at Pomona and Pasadena, January, February: obsoleta ('/), Ojai Valley, March: humeralis, one example taken by Dr. Fenyes in leaves beneath chopped meat which had been placed as a bait for Cychrus, Pasadena, January: curvata and col- laris are northern: difficilis is found in Owens Valley. Liodes, — One specimen of confusa was found at Lake Tahoe (Fenyes). 60 CALIFORNIA ACADEMY OF SCIENCES. Cyrtusa. — A single specimen of picipennis was taken by myself in the San Bernardino Mountains, August. Agathidium. — A. revolvens, rare, San Bernardino Mountains, July: concinnum, Pomona, May, not com- mon, more frequent farther north: virile, found rarely at Pomona and Riverside in early spring: pulchrum, taken on decaying mushrooms at Pomona, February: californicum and sexstriatum occur in the middle and northern parts of the State. Clambus. — One example of a species near seminulum, but smaller; Pomona, April. SCYDM^NID.E. This family is poorly represented in California, only seventeen species being known from the entire State, &nd of these but six have been found in Southern Cali- fornia; moreover all of these six are of greater or less rarity, a state of affairs surely not due entirely to the small size of the specimens or lack of proper investigation. Connophron. — C. occidens and G. digressum are repre- sented, the first by a single specimen taken at or near 'San Bernardino by Mr. W. G. Wright, and now in the collection of Captain Casey, the latter by three speci- mens taken by myself about the roots of grass in a marshy locality near Pomona. Scydmaenus ovipennis. — A single specimen has been taken at Pasadena by Dr. Fenyes in February. The three other species listed are doubtless all members of the Sonoran fauna. V. colon has occurred in San Diego County, and C. deformata is said to have been collected by Crotch at Los Angeles. Papusus macer. — This was described from a unique example taken by me under a stone at Palm Springs, on COLEOPTERA OF SOUTHERN CALIFORNIA. 61 the western border of the Colorado desert, in April. Captain Casey writes me that the type which was sent to him with other specimens for study has been lost. The remaining California!! species with their localities are as follows: Lophioderus gracilis, San Jose; L.myops, San Francisco; Drastophus Icevicollis, San Francisco; Scyd- mcenus sparsus, San Jose; 8. pacificus, San Francisco and north; S. fuchsi, San Francisco; 8. calif ornicus, northern; S. catalinus angustus, San Jose; Cephennium anophthalmicum, San Francisco; Veraphis impressa,. Lake Tahoe; Scydmcenus ovithorax Bndl., Santa Clara County. According to Casey's recent revision, the last- named species would not be a true Scydmcenus, and would perhaps require the erection of a new genus for its reception. PSELAPHID.E. Adranes. — An undescribed species found by Mr. Hub- bard in a colony of Lasius rubripes at Lake Tahoe. Articerus fuchsii var. californicus. — Occurs at Los Angeles in March (Fuchs); specimens were taken near Los Angeles by Mr. Koebele, in the nests of Cremasto- gaster lineolata. Biotus. — B. formicarius, found living in the nests of a pale brown ant, Los Angeles (Casey). Sognorus. — S. pulvereus, San Jose (Le Conte). Ctenisis. — Several specimens of dispar were taken at an electric light, Pasadena, April (Fenyes). Tyrus. — T. corticinus is not uncommon under bark of fallen conifers at Lake Tahoe. Valda. — V. frontalis, Siskiyou County (Casey). 62 CALIFORNIA ACADEMY OF SCIENCES. Tychus. — A single example of the tiny species T. tenellus was taken on the wing at Pomona in January: kexagonus, three examples also taken flying, on a warm day in March, in the Ojai Valley; and six examples taken in like manner by Dr. Fenyes at Pasadena in February: puberulus occurs at San Jose (Le Conte): sonomce, Men- docino County. Pselaptrichus. — P. tuberculipalpus was taken in the neighborhood of San Francisco in some numbers by Mr. Fuchs. Scalenarthrus. — S. hornii was found at Needles, on the Colorado River, by Mr. Wickham, and by myself further down the river at Yuma, in July, under vege- table debris accumulating in damp situations along the bank of the stream. Decarthron. — D. brendeli, Riverside and Pomona, April, in damp places near streams. Pselaptus. — P. belfragei is described from Texas, but is said to occur as far west as Yuma (Casey). Reichenbachia. — R. defortnata and R. tumidicorni* are both easily obtained in numbers by sifting along the margins of streams and in moist places nearly every- where: sagax is far rarer, having been taken by myself once at Santa Monica in early spring, and by Dr. Fenyes at Pasadena by sifting, March: the types of falli and turgidicornis were both taken by me under dead fish on the ocean beach at Santa Monica in Feb- ruary, 1892, and no other specimens were obtained until March, 1897, when both species were again found by Dr. Fenyes and myself on the ocean beach at Redondo. It is probable that the occurrence of these species on the ocean front is due to winds or other fortuitous COLEOPTERA OF SOUTHERN CALIFORNIA. 63 circumstances. The following species are also Califor- nian: informis, fundata, tumorosa, and fusticornis from the north; compar and taphrocera from the middle region; and nevadensis from western Nevada and the adjacent parts of California. Bryaxis. — B. foveata, Yuma, San Diego, Riverside, Pasadena; not common: loripes, Southern California (Casey). Batrisus. — B. zephyrinus, B. monticola and B. cicatri- cosus are from the middle Sierras: occiduus and denti- cauda from the north: pygidialis is described from "pal.." Rhexidius. — R. granolusus and R. asperulus both occur in the vicinity of San Francisco. Oropus. — Two examples of a species near, if not iden- tical with, abbreviatus ; Pasadena, March, by sifting (Fenyes). The other species, striatus, convexus, mon- tanus, interruptus and cavicauda, are all from the mid- dle or northern parts of the State. Morius. — M. occidens, Santa Cruz County (Casey). Sagola. — S. isabellce, not rare in moist situations, especially along the small streams of the foot-hill canons: grandiceps, rubida and longicollis are from the middle, and cavifrons, corticina and subsimilis from the northern portions of the State. Euplectus. — E. drbiceps, Los Angeles County (Casey): calif ornicus, not common, Pomona, Pasadena, Ojai Val- ley; by sifting; March to June. Actium. — A. californicum occurs in same situations as the preceding, and in about equal numbers: candidum, marinicum and brevipenne are described from middle California, and politum, robustulum, testaceum and pacificum from farther north. 64 CALIFORNIA ACADEMY OF SCIENCES. STAPHYLINID^E. The members of the Aleocharini are very numerous, but for the most part unstudied, and are consequently much neglected by most collectors. Falagria. — F. Iceviuscula is very common along the margin of streams in the foot-hills: an undescribed species occurred in the San Bernardino Mountains (ele- vation 5,000 feet): cavipennis was described by Le Conte from San Pedro: occidua and laticollis are described from a little south of San Francisco (Santa Clara County). Echidnoglossa. — Several species occur in the wet moss in mountain canons; some of these are probably the same as some of the following species described by Casey from the middle and northern portions of the State, viz., valida, eximia, brevicornis, gracilis, grandi- collis. Hoplandria. — A. species referred with some doubt to this genus was taken in the Ojai Valley in March. Pontomalota. — P. opaca is usually plentiful on the sands of ocean beaches: californica and nigriceps are closely allied forms found at San Francisco and Santa Cruz. Colpodota. — C. parva is said by Fauvel to occur at Mariposa. Atheta. — This genus will contain many of the species hitherto lumped under Homalota. The species are numerous, and while no special effort has been made to collect them there are in my collection some twenty or thirty species from Southern California. A. picipennis> Mann, and oraria and coriaria, Kraatz, are mentioned by Hamilton and Fauvel as having been found in Cali- fornia. COLEOPTERA OF SOUTHERN CALIFORNIA. 65 Lomechusa. — L. angusta has occurred twice, the first specimen having been found with ants in the interior of an oak gall at Pasadena (Fenyes), and the other under rubbish at Redondo beach (Daggett): montana was originally described from a specimen found under a stone at Truckee, near the summit of the middle Sierras; it has since been taken by Dr. Fenyes under bark with ants, at Lake Tahoe, and farther north at Castle Crag in like manner. Tarphiota. — T. pallidipes and T. fucicola are common on sea beaches. Tachyusa. — Four species occur more or less commonly along streams, where they may be taken in numbers by " washing " the banks. It is not yet known whether they are identical with any of the following middle and northern species: experta, linearis, laticeps, faceta, har- fordi, crebrepunctata. Tinotus. — Two examples of caviceps were taken at Pomona in January. Myrmedonia. — M. sonomce is described from Sonoma County, and M. fauveli is said by Casey to occur near Los Angeles. Anepsiota. — A. insignis, San Francisco. Phlceopora. — Two species so referred were found at Pomona and San Diego. Calodera. — C. attenuata, middle California (Monterey and Napa counties). Polystoma. — P. arenaria, not very abundant at Redondo beach, San Diego, Santa Monica, and the islands off the coast. I have seen one specimen from 5 June 5, 1901. 66 CALIFORNIA ACADEMY OF SCIENCES. San Bernardino, but all others are from the immediate vicinity of the coast. P. pacifica is described from Santa Barbara. Microglossa. — Fauvel mentions the occurrence of suturalis in " California." Aleochara. — A. vulcicollis occurs only on the beaches, where it is quite abundant; several other species are generally common in excrementitious matter. One example of what seems surely identical with the Euro- pean puberula has been taken at Pomona. Maseochara. — M. valida, found at Pasadena, April to July, under decaying fruits and vegetables: puberula, one example at Arrowhead Hot Springs, May 31. Thiasophila. — Several specimens of a species taken at Pomona early in September: asperata occurs at Lake Tahoe and Truckee. Isoglossa. — A fine species, doubtfully referred to this genus, occurred in the San Bernardino Mountains in July: arcuaia was described from Lake Tahoe. Oxypoda. — About five species of this genus are known to me from Southern California. Casey describes fusti- ger from Humboldt County, and californica from "Cal." Myrmecochara. — An undescribed species from Lake Tahoe (Schwarz). Autalia. — A. elegans, Lake County. Thinusa. — T. maritima is described from Oakland. I have found a closely allied if not identical species on the beach at Santa Barbara. Silusa. — S. vesperis, Humboldt County. Bolitochara. — B. calif ornica, common throughout the State in or about fungi: nigrina is found near San Francisco and in Humboldt County. COLEOPTERA OF SOUTHERN CALIFORNIA. 67 Leptusa. — A single specimen of a species taken at Pomona. Oligota. — A minute species is sometimes beaten abun- dantly from the branches of trees; it is quite likely not separable from pusillima. Sipalia. — S. frontalis, "California."

Somatium. — S. oviforme is occasionally found in some numbers at Pomona, usually by beating. Gyronycha. — G. obscura, rather common at times along the banks of streams, Pomona; a smaller form found in the Ojai Valley seems different. G. attenuata occurs at Monterey and in Napa County. Bamona. — B. falliana is not rare at Pomona along the margin of streams. Myllaena. — One example of a species taken in Los Angeles County. Acylophorus. — A. pronus, taken only in small num- bers at Pomona, January, and Palm Spririgs in April. Heterothops. — H. fumatus var. californicus and H. carbonatus occur not uncommonly near springs or streams: pusio is less frequent in like situations: occi- dentis was taken deep in the detritus of hollow oak stumps at Pomona, February. Quedius. — The species occur for the most part under stones or drift along the margins of streams in the foot- hills and mountains, though fulgidus is likely to be found almost anywhere. Q. capucinus and Q. limbifer are 68 CALIFORNIA ACADEMY OF SCIENCES. most often taken: explanatus and erythrogaster are rather scarce: desertus is found east of the mountains: prostans is rather common in wet moss, at considerable elevations, but is only rarely taken in the lower valleys: debilis and seriatus are northern; of the latter I secured several examples near San Francisco (Marin County). Thinopinus. — T. pictus is not rare on various beaches from San Diego northward; specimens in my collection were taken at Redoiido, February; Coronado, June; Santa Monica, August. Creophilus. — G. villosus, wide-spread, but usually not abundant; very common on San Clemente Island in May and June, about the carcasses of birds and foxes shot by hunters. Hadrotes. — H. crassus is taken on sea beaches; Redondo, March to May; Santa Barbara, February; San Diego; not numerous.

Belonuchus. — B. ephippiafus was taken abundantly by Dr. Fenyes and myself under rotting squash, etc., Pasa- dena, Pomona, etc., July to October. Specimens of an apparently undescribed species were taken in decaying yucca, in mountains near Pomona, May. Philonthus. — I have found nitescens only along the wet margin of a small salt lake or pond at Redondo, April: alutaceus, taken sparingly in a low, marshy spot COLEOPTERA OF SOUTHERN CALIFORNIA. 69 near Pomona, November to January: semiruber, rare; two examples only taken along a stream in foot-hills near Pomona: hepaticus, very scarce, same locality as preceding: flavolimbatus , has occurred at Pasadena in November, but is *very rare west of the mountains; not rare at Yuma: grandicollis, not common; my specimens were taken in the bed of the Los Angeles River, near the city, in August: longicornis, widely distributed, but not very common: discoideus, rare at Pomona about stables: alumnus, the form with red thorax and elytra is very common at Yuma, on the river shore: pettiti and trian- gulum, not rare, many localities: ferreipennis , rather infrequent, Pomona, June to September: sordidus, com- mon about houses and stables: versutus, two speci- mens only, San Bernardino Mountains, elevation 5,000 feet: virilis, not rare, same locality as the last: nigritu- lus, everywhere abundant: instabilis, has occurred on one occasion at Mojave: quadmlus, not infrequent in the foot-hills near Pomona: lecontei, not common, but widely dispersed. In addition to the above the follow- ing occur within the State: politus and albionicus, from San Francisco, north; dunalis, at Alameda; puberulus, from Tulare, north; theveneti, crotchi, punctatellus and picicornis, in the middle Sierras and Lake Tahoe region ; decipiens, bidentatus , siegwaldi, bucephalus, varians and caurinus, from the north; furvus and ventralis, from "Cal.," but probably not southern. There are in my collection several probably undescribed species, for the most part represented by females only. Actobius. — A. ocreatus, not uncommon at Los Angeles, Pomona, etc.: sobrinus, one specimen, Fort Yuma (Horn): puncticeps, abundant everywhere in the foot- hills and mountains; rare in the valleys: gratus, widely diffused, but nowhere common: pcederoides, very common 70 CALIFORNIA ACADEMY OF SCIENCES. everywhere from the sea-level to moderate altitudes, both east and west of the mountains: formosus, not common, Pomona and Pasadena: eltgantulus, usually not plentiful, but at times found in numbers, Pasa- dena and Pomona. All the species are found only in the vicinity of water. The following occur in middle California: senilis, infanus, and semipunctatus — the lat- ter now identified with Bisnius procerulus Grav. Cafius. — The species of this genus are confined to the seacoast, and are often found in great numbers in or beneath decaying seaweed, or other littoral rubbish. C. canescens is our most abundant species, but seniinitens, lithocharinus, and luteipennis often occur nearly as plen- tifully: decipiens is said to occur rather commonly at San Diego: sulcicollis and opacus are rather rare. All the species, except setiiinitens and decipiens, have been reported from one or another of the islands. Xantholinus. — X. cephalus, not rare in the Sierras, under bark: picipennis, common in fields and pastures beneath stones, cow-droppings, etc.: dimidiatus, "San Bernardino, Mojave Desert," Pomona, May; in decaying yucca; rare: obscurus, not rare in damp situations near Pomona, September to February: nanus, San Diego; not seen by the writer: pusillus, not frequent, Riverside and Pomona. Leptacinus. — L. brunnescens, common in most locali- ties under any object upon the ground, especially from November to May: pallidulus, one specimen, Fort Yurna (Le Conte). There are three undescribed species from Southern California in my collection, of which one, at least, is not rare. L. grandiceps was described from San Francisco and parcus from San Jose; 1 have taken the latter at Sacramento. COLEOPTERA OF SOUTHERN CALIFORNIA. 71 Othius. — 0. calif ornicus, Mann, "Alaska and Califor- nia." I have seen specimens taken at Stewart's Point (Ricksecker), and at Monterey (Fenyes). Baptolinus. — B. punctiventris is not uncommon under bark at Lake Tahoe; found also by Mr. Daggett, on Mt. Whitney, at an elevation of 11,000 feet. Stenus. — 8. renifer, S. incultus and 8. gilw occur on the Colorado River, the two latter being moderately com- mon in Yuma early in July: sculptilis and californicus are very abundant along mountain streams, the former also occurring occasionally in the valleys: costalis, less common in same situations: terricola, one example, San Bernardino Mountains: znnicus and pacificus are found everywhere in the lower country, the former common at times, the latter always abundant: insignis, not rare at Pomona, November to May: vestalis, one example, Riverside: sayi, found in some numbers about the roots of grass in marshy spot near Pomona, January; not seen elsewhere: pinguis, common in many localities, occurring in prodigious numbers at times; hundreds have been found on every square yard of ground about a small lake near Pasadena, great numbers flying about and swarming on the shrubbery about the lake at the same time: Icetulus, rather rare, Ventura, Riverside, Pomona; March to May: alveolatus, one example, so named, San Diego: lucidus, a single example taken at Pomona, May. The following additional species are recorded from the State: tristis, luctuosus, luculentus and vacuus from the middle regions; corvus from Fort Tejon; dives and subgriseus from the north; ellipticus, colonus, villosus, exilis, and pollens from " California " without definite locality. 72 CALIFORNIA ACADEMY OF SCIENCES. Cryptobium. — This genus is not well represented in California, californicum being the only species known from west of the mountains; it is not rare, especially in the foot-hills and mountains. C. tumidum is recorded from California, Arizona and Utah, and is doubtless confined to the region east of the mountains. I have taken females of an undetermined species at Yuma. Lathrobium. — L. puncticeps, rather rare : jacobinum, very common along any of the streams from the Sierras: californicum, rare, Pomona, May ; Redondo beach, March : lituarium, a few specimens taken at Indio and Yuma : subseriatum occurs in the northern part of the State. There are three undescribed species in my col- lection, one from Southern California (Pasadena), and the other two from the north. Caloderma. — C. rugo.m, C. mobilis and C. reducta are all abundant under vegetable debris near water, occurring sometimes in great numbers in damp places in the mountain canons: continens is recorded from San Diego; it is probably not different from rugosa. Three species not yet determined have been found in the canons near Pomona. The other species described by Casey — angulctia, con- tracta, luculenta and tantilla — occur in the middle and northern parts of the State. Oligopterus. — 0. cuneicollis, San Francisco. Medon. — M. malaca occurs in the same situations as the species of Caloderma, but specimens are not quite so numerous: latuiscula, li Southern California and Lake County" (Casey). Several unidentified species are from Southern California, while the following are from mid- dle and northern California: sinuaticollis , convergens, COLEOPTERA OF SOUTHERN CALIFORNIA. 73 tepida, puberula, sublesta, consanguine a, contigua, luc- tuosa, retrusa, gregalis, mimula, languida.

Sci., 2nd Ser., Vol. IV, 1894, p. 319. 74 CALIFORNIA ACADEMY OF SCIENCES. Tachinus. — T. agilis and T. debilis are both rather widely distributed and moderately common. The genus is better represented farther north, semirufus and angus- tatus occurring in the middle regions, and tachypo- roides, pallipes and instabilis in the upper portions of the State. A female specimen taken at Lake Tahoe is referred somewhat doubtfully to memnonius. Tachyporus. — T. calif ornicus, exceedingly abundant nearly everywhere; often seen flying at twilight in spring and early summer: natidulus, rare, Pomona, Lake Tahoe. Cilea. — One example of G. silphoides from Pasadena, taken in February (Fenyes). Erchomus. — A single specimen of E. punctipennis w&B taken in the San Bernardino Mountains.

A single specimen of a possibly undescribed species has been taken at Pomona. Mycetoporus. — M. hiuuidus, " Michigan to Florida and west to California;" I have not yet seen it here: splendidus or a closely allied species has been found in the Santa Cruz Mountains. Habrocerus. — H. tarsalis is described from San Mateo. Olisthaerus. — 0. megacephalus, included on the author- ity of Fauvel; it is unquestionably northern. COLEOPTERA OF SOUTHERN CALIFORNIA. 75 Pseudopsis. — P. obliterata, P. detrita and P. minuta occur not uncommonly, and occasionally in large num- bers, in the vegetable detritus along our mountain streams; the first named species was described from the valley of the Gila. Oxyporus. — Specimens of an undescribed species have been taken at Lake Tahoe in Nevada by Mr. Schwarz, and on the California side of the lake by Dr. Fenyes. Bledius. — The species are numerous, and are found for the most part burrowing in wet sand or mud on the margins of fresh-water streams and ponds. B. diago- nalis is recorded by Le Conte as occurring on salt marsh at San Diego: cribricollis appears to be confined to the sea-coast; I have seen it in abundance on the beach at Santa Barbara in February, but it is likely to be plenti- ful at all seasons: ferratus, jacobinus, flavipennis and eximius are all reported from San Diego, but I do not know them in nature: opacifrons, San Diego and Los Angeles: luteipennis, San Bernardino: armatus, River- side, Pomona, Long Beach; not common: nitidiceps, Los Angeles, Wilmington (Le Conte), Pomona, one example in nearly dry bed of brook, November: relictus, two examples, Pomona: laticollis, common, many locali- ties: rusticus, rare, Pomona: ruficornis, abundant every- where: clarus, Riverside, Pomona, not common; pleu- ralis, occasionally common; once taken in numbers in San Dirnas Canon near Pomona, April: ornatus, not rare near the sea-coast, rare inland; taken in numbers at Redondo, February: forcipatus, Yuma (Le Conte): punctatissimus and phytosinus are recorded from "South- ern California" without definite locality. A single speci- men of a small black species not yet determined has been taken at Pomona. The following occur further 76 CALIFORNIA ACADEMY OF SCIENCES. north: deceptivus, sp. nov, Kern County; of Casey's species, strenuus and monstratus occur at San Fran- cisco, lectus, foraminosus, gentilis, gracilis and bicolor somewhat farther north, parvicollis in Mendocino County, monticola at Lake Tahoe, and villosus from « California". Platystethus. — P. americanus occurs chiefly about cow-droppings, both east and west of the mountains. Oxytelus. — 0. sculptus, not rare about stables, etc.: sobrinus, one example, Pomona, December: laqueatus, nitidulus, vegrandis, and niger are found near San Fran- cisco and farther north, the last-named species and montanus occurring at Lake Tahoe. Haploderus. — H. flavipennis and H. cephalotes are both often taken in the vegetable detritus which collects in damp situations along streams or ponds: linearis is quite surely more northern in habitat: annectens, reported from San Francisco and Sonoma County. Trogophlceus. — T. giice and T. pacificus are common under rubbish about gardens and along water courses at Pomona: diffuses occurs along streams in the higher parts of the Sierras: prominens, one example, Los Angeles (Casey): confinis, deMlis, and blediimus are described from San Diego: paupercuLus &ndfilum, from Yuma: armatus, occiduus, and lithocharinus are from the middle coast region: lapsus and obliquus, from the mid- dle Sierras (Truckee and Lake Tahoe): sculptilis, from Sonoma and Lake counties: insolitus, from Hoopa Valley, Humboldt County. Wickham reports giice, dentiger, and tantillus from Yuma. There are several unidentified species in my collection, some of which may be unde- scribed. COLEOPTERA OF SOUTHERN CALIFORNIA. 77 Apocellus. — A. analis and A. gracilicornis are both rather common near water, especially about reservoirs^ irrigating ditches., etc., in cultivated regions: sphceri- collis, one example, Pomona, April. Ancyrophorus. — A small colony of A. planus was once taken in drift in a mountain canon near Pomona. Thinobius. — T. hesperius, Yuma (Casey): two uniden- tified species from Southern California, one of which is quite surely undescribed, and the other is probably oxytelinus. The following species are described from farther north: macropterus , "various localities" (Le Conte); sonomce, Sonoma County; gracilicornis, Santa Clara to Sonoma counties: validus, Marin County and north. Zalobius. — Z. serricollis, common under rubbish near water, more especially in the foot-hill and mountain canons: spinicollis, middle and northern parts of the State; found in situations similar to the last. Asemobius. — A. ccdatus, "California" (Horn, " Cole- optera of Baja California," Supp. I.)-* Deleaster. — D. concolor, from San Francisco and north, Geodromicus.- — G. temporalis, quite rare along moun- tain streams, near Pomona, September: kumboldtianus, northern.

Artochia. — A. productifrons, from Santa Clara County. Unamis. — U. truncata, from Middle Sierras. Lesteva. — L.fusconigra, from Eldorado County. * Proc. C'al. Acad. Sci., 2nd Ser., Vol. V, 1895, p. 238. 78 CALIFORNIA ACADEMY OF SCIENCES. Brathinus. — B. californicus was found in some num- bers by Mr. Hubbard at Lake Tahoe, where it occurred in wet moss along a mountain stream; other specimens were found at Sisson. Amphichroum. — A. floribundum, very abundant in many localities, especially on flowers of Ceanothus, in April: puberulum, described from San Diego; specimens taken in the San Bernardino Mountains are so referred with some doubt. The species are more numerous in the middle Sierras, and from there north to Vancouver. The following are recorded from the State : sparsum, scutatum, opaculum, flavescens, pallidum and maculatum from the middle Sierras (Mariposa and Tahoe); bino- tatum, pilosellum, alutaceum, modestum, from the region about and to the north of San Francisco; testaceum and crassicorne from still further north. Tanyrhinus. — T. aingularis occurs in the Santa Cruz Mountains, but is quite rare. Lathrimaeum. — One example of L. subcostatum obtained in the mountain canon near Pomona, March. The fol- lowing are recorded: pictum, northern; nigropiceum, Santa Cruz County; spretum, Siskiyou; atrocephalum, Tahoe (Fauvel). Homalium. — This genus is numerously represented in California, about half our listed species being recorded from the State. H. plagiatum has occurred in mushrooms, at Pomona, in early spring, and theveneti at Santa Barbara and Redondo, on the ocean beach, in March; but, aside from these, I am able to find definite records of only four species from Southern California, viz.: strigipenne, San Diego; repandum, "Southern California and Texas" (Fauvel); humilet San Bernardino Mountains, identified by Casey; alutaceum, San Diego (Fauvel). When the COLEOPTEKA OF SOUTHERN CALIFORNIA. 79 whole State is considered, we must add the following: algarum and rugipenne, from San Francisco; ater, from Santa Cruz; pacificum, from Siskiyou; longulum, pusil- lum, megarthroides, rivulare, lapponicuvti, ccesum and fractum, from "California," without indication of local- ity. It is probable that few, if any, of these latter will be found within our region. Several species in my collection from Southern California are as yet un- identified. Anthobium. — A. atriventre and A. nigerrimum occur on flowers, the former very abundantly at Pomona, in April. Two other unidentified — possibly undescribed — species are known to me from Pomona, Ojai Valley and Palm Springs. The species of this genus are somewhat numerous, but not identifiable as the literature now stands. The following are to be added to the above: aurifluum, diversicolle and subangulatum, from Lake Tahoe; gilvipenne and punctatum, Santa Cruz County; fraternum, northern; calif ornicum, "California." Orobanus. — 0. rujipes, San Diego and Pomona; one example from the bank of a mountain stream near Pasadena. Protinus. — Two species of this genus have been found on decaying mushrooms at Pomona, in early spring; neither species has as yet been identified. In the mountains of the middle coast region occur limbatus, basalis and salebrosus: maklini is middle or northern: sulcatus is described from the middle Sierras. Megarthrus. — M. pictus, reported from middle and northern portion of the State. Lispinus. — L. calif ornicus , not rare in many locali- ties, under bark: linearis, less frequent, Riverside, 80 CALIFORNIA ACADEMY OF SCIENCES. Pomona and Palm Springs — at the last-named locality found under cottonwood bark. Trigonurus. — All our species occur from middle Cali- fornia north, under bark of conifers. T. edivardsii has been taken in Los Angeles County (fide Fuchs). Micropeplus. — M. punctatus, occurs at San Diego (Crotch): a single example of a probably undescribed species was taken at Pasadena, in March, by sifting (Fenyes): tesserula and brunneus are more northern. TRICHOPTERYGID.E. These minute things have not been systematically searched for, and the number recorded from Southern California, and indeed from the whole State, is very inconsiderable. * Actidium.— Four species are on record: robustulum, granulosum and attenuatum from the middle coast region (Santa Cruz), and poliium from " California." Motschulskium. — M. sinuatocolle occurs plentifully at times on various beaches from San Diego northward. Ptilium. — An unidentified species has been taken sparingly at Pomona: columbianum, humile and collani are said to be from " California." Ptenidium. — P. pullum, quite common in vegetable detritus near water at Pomona, etc. Trichopteryx. — T. laticollis] ' 'Southern California," in- Horn Collection: californicus and crotchii bear " Califor- nia" labels in the Le Conte Collection; and sitkaensis bears a gilt locality label which is supposed to signify a like origin. Smicrus. — S. filicornis, from Colorado River; Le Conte Collection. COLEOPTERA OF SOUTHERN CALIFORNIA. 81 HYDROSCAPHID.E. Hydroscapha. — H. natans is probably not a rare in- sect, though very seldom taken; when one is discovered a considerable number may usually be obtained by patient search. I have taken it close to the bank in a mountain stream, and also in a muddy spot in a cow pasture near Pomona; Crotch took the first examples in the Los Angeles River. Sphaerius. — S. politus is rather common on the sandy margins of streams, and is often started in numbers by "washing" the banks. SCAPHIDIID.E. Scaphisoma. — S. castaneum, not very common, found in and about decaying and fungus-grown wood in damp or wet places: rufulum, occurs at Yuma (Le Conte). PHALACRID.E. The species of this family are for the most part com- mon on flowers; they are difficult to identify with cer- tainty, and have been generally neglected by collectors. Phalacrus. — P. ovalis, common at Pomona, Riverside, etc.: of penicillatus (so named by Casey) a number of specimens were taken in the San Bernardino Mountains: conjunctus, same locality as the last; also San Diego (Casey). The species here called ovalis is possibly not that species; it was pronounced " n. sp." by Casey, to whom specimens were sent for identification, but a com- parison with Le Conte's types shows scarcely any tangible 6 July 15, 1901. 82 . CALIFORNIA ACADEMY OF SCIENCES. difference; in fact, the three species here named are separated by characters of very doubtful significance. Olibrus. — 0. wickhami, sp. nov., Southern California (Casey); many specimens collected in San Diego County by Dunn. Acylomus — A. nebulosus, taken at Yuma, in March (Daggett). Eustilbus. — E. apicalis, widely distributed and rather common; I have beaten it in some numbers from a very tall dried grass at Pasadena, in February: obtusus and nanulus both occurred plentifully about the roots of grass in a marshy spot near Pomona, in January: notab- ilis occurred sparingly in the same situation: aquatilis, described from San Jose. CORYLOPHIDJS. Sacium. — S. amabile, found under bark of sycamores, sometimes in large numbers. I took on one occasion over seven hundred examples from beneath the bark of a fallen sycamore in the Ojai Valley, early in March: decolor, rare, Pomona: scitulum, described from Yuma (Le Conte). Sericoderus. — S.flavidus is found in debris near water, Riverside, Pomona, etc. Orthoperus. — Two apparently undescribed species have been taken; one of these was found plentifully about grass roots, in moist situations, in winter; of the other there is but a single example from the Ojai Valley. ^)nigmaticum. — ^E. calif ornicum, not rare, Santa Bar- bara, Ventura, San Diego; found by beating. COLEOPTERA OF SOUTHERN CALIFORNIA. 83 COCCINELLID^;. Since the following notes were written there has come to hand a Revision of the American Coccinellidse by Captain Casey. Among the large number of new species are many that are accredited to California, but as not a few appear to me to be merely slight color variations of old forms, I have thought it best to exclude them till the matter could be more carefully investigated. Except in the case of Exochomus, no reference will be made to this paper. Anisosticta. — A. seriata, plentiful in September, along the shore of San Diego Bay (Blaisdell). Nsemia. — N. episcopalis, one specimen, swept in marshy spot at Tallac, Lake Tahoe (Fenyes). Megilla. — M. maculata, Colorado River and Palm Springs; I have not seen specimens from the maritime slope as yet: vittiyera, not uncommon, especially 011 weeds or low herbage, in river bottoms. Eriopis. — E. connexa, " California" (Mulsant). Hippodamia. — H. ambigua and H. convergens are exceed- ingly abundant at nearly all seasons throughout Southern California, and intermediates are common: parenthesis, very rare, on squash vines, at Poway (Blaisdell): 5-sig- nata, an example in Mr. Fuch's collection from Los Angeles County, and bearing the label lecontei, is scarcely distinguishable from eastern specimens of 5-signata; it is more than likely that lecontei is only a slight variety of Kirby's species: spuria, San Diego County (Fuch's collection). Coccinella. — Blaisdell records 9-notatafrom San Diego County, but I have not yet seen typical specimens from 84 CALIFORNIA ACADEMY OF SCIENCES. our region; the var. franciscana is found in most local- ities, and is not rare. C. transversoguttata var. trans- versalis was abundant during the season of 1897, on the islands, and occurred rather frequently at Pasadena, but I do not recall seeing it either before or since: calif or- nica is rather common every season, and in nearly all localities: monticola has been taken by Dr. Fenyes at Lake Tahoe (Mt. Tallac, elevation 9,000 feet), and pro- longata is said by Crotch to occur in California; these two species are exceedingly closely related, and I am inclined to doubt their distinctness. According to Fauvel, the European 11-punctata Linn, has been taken in California. Cycloneda. — C. sanguinea is common and widely dif- fused: oculata, rare, Pasadena: abdominalis , moderately common, especially in cultivated grounds. Adalia. — A. frigida, " California," must be northern: bipunctata var. humeralis, one example, Santa Rosa (Ricksecker). Harmonia. — H. picta, common on pines in the Sierras. Anatis. — A. rathvoni, " California, Oregon ": subvit- tata, middle and northern Sierras: an undescribed spe- cies from Lake Tahoe, elevation 9,000 feet (Fenyes). Mysia. — M. hornii, San Bernardino Mountains, July; one example beaten from a pine (identified by Dr. Horn); it is not easy to distinguish this from speci- mens from the middle Sierras which pass as Anatis sub- vittata, in fact, I believe they are the same thing; it is possible that we do not know Mulsant's species. Psyllobora. — P. %0-maculata var. tcedata, very com- mon everywhere, by beating. COLEOPTERA OP SOUTHERN CALIFORNIA. 85 Chilocorus. — C. bivulnerus, plentiful about, orchards and cultivated grounds everywhere: cacti, generally much less frequent, probably more common in the southeast. Exochomus. — E. pilatii, generally quite rare; on one occasion I found it in some numbers in an olive orchard at Pomona, where it was feeding on the black scale with which the trees were infested; it has also been found rather plentifully at Pasadena, by Mr. Daggett, on cer- tain pepper trees (Schinus molle) infested by this same scale. E. californicus occurs in the Sierras from the San Bernardino Mountains to Siskiyou, and also in Marin County: fasciatus is common throughout our district: childreni has occurred at Pasadena and Redondo: histrio, Pomona, in the foot-hills. Cryptognatha. — C. pusilla, abundant near Pomona, on live-oak, October: catalince, a small number taken by beating on Catalina Island, August; probably not differ- ent from the preceding. Smilia. — S. reversa, occurs on pines in the Sierras (San Bernardino and Lake Tahoe), and is apparently not uncommon: ovalis, specimens so referred are com- mon on live-oak at Pomona, September to November. Hyperaspis. — The species occur by beating and sweep- ing the shrubbery and herbage of uncultivated ground. H. fimbriolata and its variety dissoluta are represented in my collection by single specimens taken at Pomona in May and June: lateralis is our commonest species: undulata (?) is also rather common and very variable: tceniata, not rare at Pomona and Pasadena: excelsa, rare, Pomona, November; Pasadena, April; San Bernardino Mountains, July: spiculinota, not common at Pasa- dena and Pomona; usually if not always on a species of Ob CALIFORNIA ACADEMY OF SCIENCES. tall grass or rush both living (June) and dead (Novem- ber): annexa, not rare; Pomona, June to November: tristis, specimens so referred by Dr. Horn were bred in numbers from cactus by Professor A. J. Cook, at Clare- mont: postica was described from northern California, and osculans and 4-oculata from " California " simply. Hyperaspidius. — H. trimaculatus, widely dispersed but not very common: arcuatus, Colorado River (Le Conte). Scymnus. — A few specimens of tctdatus were beaten from pines in the San Bernardino Mountains: sordidus, scarce; San Bernardino, Pomona: guttulatus, occurs at Pomona, Pasadena, Redondo, Catalina Island, etc., most frequently in March and April, but at no time common: nebidosus, tolerably common in the foot-hills near Pomona; taken also in the Ojai Valley and at Cata- lina Island: pollens, common on live-oak nearly every- where, especially from October to February: mimus, two examples only; Riverside and Pomona: cinctus, moderately common and wide-spread: pacificus, rare; Sierras, 3,000 to 5,000 feet elevation: flebilis, two ex- amples taken at Yuma: cervicalis, rare; Pomona and Catalina Island: mceginicoiList our commonest species and the only one occurring in orchards as well as on wild growth: ardelio, nearly as abundant as the pre- ceding and very widely dispersed, but does not occur on cultivated lands: punctum, common, especially on live-oak, in many localities: nanus, less frequent than the preceding but equally wide-spread: coniferarum, very abundant on pines in the southern Sierras. The fol- lowing species are more northern in habitat: debilis, San Jose and Alameda; bisignatus, Siskiyou; phelpsii, northern; caurinus, Owens Valley (Horn). Scymnillus. — 8. aterribus is moderately common in the San Bernardino Mountains, probably on pines; taken by beating. COLEOPTERA OF SOUTHERN CALIFORNIA. 87 Cephaloscymnus. — C. occidentalis, rare; Long Beach, Pomona, Catalina Island: ornatus, generally uncom- mon; Pomona, San Diego, Catalina Island, San Ber- nardino Mountains. These two species are not con- generic, and it is probable that a new genus will have to be erected for the latter. Rhizobius. — R. lopanthce is now found quite fre- quently in many localities west of the mountains; it is the only one of the introduced species that has so thoroughly established itself as to be independent of artificial support. ENDOMYCHID^E. Two specimens of an undescribed species allied to Mycetcea were found in rotten wood in a canon near Pomona in June. Phymaphora. — P. californica, " San Francisco and western Nevada'* (Horn). Xenomycetes. — X. morrisoni is found at Castle Crag in fungus (Fenyes). Aphorista. — A. morosa and A. Iceta occur rather un- commonly at various places in the foot-hills and moun- tains; both are fungivorus. Mycetina. — M. hornii occurs sparingly under bark at Lake Tahoe: limbata is probably from the middle regions. EROTYLIDJE. Languria. — A single specimen of californica was taken at Redondo, on Astragalus crotala,rce: convexicollis, Owens Valley. 88 CALIFORNIA ACADEMY OF SCIENCES. Dacne. — D. californica, common at Pomona, Pasadena, Ojai Valley, etc., in fungi; March: picea, described from "California." Tritoma. — T. californica is found abundantly in fungi, Ojai Valley, March. COLYDIID^E. Rhagodera. — R. tuberculata, rare, Pomona, May. Anchomma. — A. costatum is usually rather rare, occur- ring singly or in small numbers under stones; once taken in considerable numbers beneath a stone with Pheidole hyatti at Redondo in April. Megataphrus. — M. tenuicornis is northern (Casey). Synchita. — S. variegata, rare; taken occasionally on the wing on warm days in January and February at Pomona; once taken in some numbers under bark at Pasadena in February (Fenyes). Ditoma. — D. ornata,, not rare under bark; Pomona, Yuma, San Bernardino, etc.: sulcata, usually not com- mon; once found in numbers under the bark of an old dead stump nearly covered with a woody fungus; Pomona. D. suffusa is probably a color variety of ornata; it occurs at Yuma under bark with the typical form. Phloeonemus. — P. catenulatus, Yuma (Horn). Coxelus. — C. serratus and 0. pacificus occur in the middle coast regions. Lasconotus. — L. linearis, not common; on trunks of recently felled alders, San Bernardino Mountains, Au- gust: servus, a single specimen, flying at twilight; San Bernardino Mountains: pusillna, common under pine COLEOPTERA OF SOUTHERN CALIFORNIA. 89 bark in the same locality as the preceding: complex is northern, while vegrandis, pertenuis, nucleatus and api- calis inhabit the middle coast region. Aulonium. — A. longum, rare under pine bark; San Bernardino Mountains: paratttlopipedum, one specimen taken in "California" (Horn). Aglenus. — A. brunneus, one or two examples were taken each morning from beneath a portion of the trunk of a recently cut fig tree; others were sifted from stable refuse near by; Pomona, October, February. Oxylaemus. — A few specimens of calif or nicus were taken flying at twilight about lumber piles; San Ber- nardino Mountains. Deretaphrus. — D. oregonensis, middle Sierras and north. Cerylon. — C. castaneum, not common; found once under oak bark in the San Bernardino Mountains: californicum and sylvaticum are described by Casey from Lake Tahoe. Lapethus. — L. discretus, found under bark; Humboldt County (Casey). RHYSSODID^E. Rhyssodes. — R. hamatus, not common, under bark of fallen conifers, San Bernardino Mountains; much more plentiful at Lake Tahoe and further north. CUCUJHXE. Silvanus. — $. xurinamensis, occurs commonly in stored cereals, etc. : bidentatus, "not very common, occurs with the preceding;" San Diego County (Blaisdell): 90 CALIFORNIA ACADEMY OP SCIENCES. imbellis, one example; San Diego (Blaisdell): nitid- ulus, now referred to planatus, was described from Cali- fornia. Cathartus. — C. advena, common about gardens, stables, etc.: opaculus, not very common but generally diffused; Yuma, San Bernardino, Pomona; once taken in some numbers under bark of eucalyptus in December. Nausibius. — N. davicornis, "Commercial storehouses occasionally" (Blaisdell). Prostomis. — P. mandibularis is northern. Narthecius. — N. grandiceps is very rare; I once took about a dozen specimens from the burrows of Pityoph- thoruspubipennis, San Bernardino Mountains, in August. Casey has described simulator from Santa Cruz County. Pediacus. — P. depressus, not common, under bark, San Bernardino Mountains: fuscus has been taken near San Francisco (Marin County) by Van Dyke. Cucujus. — C. clavipes var. puniceus, Lake Tahoe and north. Laemophlceus. — L. biguttatua, usually not common; found flying late in the afternoon of warm days in early spring; occurs at times in large numbers under decay- ing and fungus-covered bark of dead sycamores (Blais- dell): nitens, one or two examples taken at Pasadena in March by Dr. Fenyes: horni, sometimes found in large numbers under bark of dead sycamores, several hundred having been once taken in this way in the Ojai Valley in March: cephalotes, rare, under bark of various trees, Pasadena, Los Angeles, San Diego, etc.: ferrugineus, not common, Los Angeles: puaillua, Colorado River (Le Conte). COLEOPTERA OF SOUTHERN CALIFORNIA. 91 Lathropus. — L. vernalis, not common; about a dozen specimens once taken under bark at Pasadena in Feb- ruary (Fenyes). A careful comparison of the type of pubescens satisfies me that this is merely a specimen of vernalis in which the pubescence of the upper surface is more distinct than usual. This pubescence is plainly visible in specimens of vernalis in my own and in the Le Conte Collection, and, I suspect, may always be seen in fresh specimens. Brontes. — B. dubius var. truncatus is rather common in many localities, especially under oak bark. CRYPTOPHAGIDJE. Henoticus. — H. serratus, not rare, Pomona, Ojai, etc.; taken most frequently on the wing about houses and gardens on warm evenings. Cryptophagus. — A species quite common at Pomona is referred with confidence to debilis; the species was described from San Diego: cellarisis said to occur at San Diego; it must be closely allied to debilis if it is really distinct: lecontei, occurs at Yuma. Two other species in my collection, from Pomona and San Bernardino Moun- tains, are not identified. Atomaria. — At least three species are more or less common under debris and about the roots of plants in damp places; one of these is probably Icetulus (described from San Jose), which is somewhat variable in color according to the series in the Le Conte cabinet. A. fits- cicollis is said by Fauvel to occur in California. MYCETOPHAGID^E. Mycetophagus. — M. californicus and M. plurigvMatus are both uncommon, occurring in fungus; both species 92 CALIFORNIA ACADEMY OF SCIENCES. have been taken in Pasadena rather early in spring, and I have found the former in the San Bernardino Moun- tains in August. Litargus. — L. balteatus, common in decomposing vege- table matter; found in many localities. Typhcea. — T. fumata, plentiful everywhere. Berginus. — B. pumilus,Yurna, Pomona, Redondo, San Diego, Long Beach; sometimes abundant on certain composite flowers, especially near the coast. Myrmechixenis. — M . latridioides, taken not rarely about houses and gardens, Riverside, Pomona, Pasa- dena. Diploccelus. — An undescribed species taken at Yuma (Wickham). DERMESTID^E. Byturus. — B. grisescens has been beaten in numbers from live-oak at Pomona and Santa Barbara, during January and February. Dermestes. — D. marmoratus, D. mannerheimii and D. vulpinus are everywhere common: talpinus is less com- mon: tristis, rather scarce: carnivorus, not rare, but occurs, so far as I know, only in the southeastern region: rattus, a species quite distinct from caninus, is found in the middle coast region and also in the middle Sierras: lardarius, has been taken at Lake Tahoe by Dr. Fen yes. Perimegatoma. — P. varieyatum, rare, Pomona and Pasadena: cylindricum and falsum are also Californian, but I do not know from what locality. Attagenus. — A. piceus, occurs everywhere, in houses and on flowers: varicolor, southeastern region (Horn): COLEOPTERA OF SOUTHERN CALIFORNIA. 93 perplexus has been taken at Castle Crag (Fenyes): hornii, recorded from the "Pacific States" by Jayne, but I have seen no specimens from California; it is rather frequent in Arizona, and it is likely that it may occur in the adjacent desert region of California. Trogoderma. — T. ornatum, common and widely dis- persed: sternale, much rarer; I have taken a single example on Catalina Island. Anthrenus. — A. scrophularicv and A. verbasci are both abundant everywhere on flowers; the latter has on one occasion been reared from larvae found in one of my duplicate boxes. Cryptorhopalum. — C. apicale, common on blossoms of willow in April: bcdteatum, much scarcer; on flowers, Pomona: ruficorne, two examples; Pomona and Yurna. An undescribed species is not rare at Pomona and Pasadena. Orphilus. — 0. niger is common nearly everywhere on flowers. HISTERID.E. Hololepta. — H. yucateca is said by Blaisdell to be rather plentiful at San Diego from May to November, in decaying fruit of Cucurbita, Echinocactus viridescens, and leaves and stalks of Opuntia occidentalis. I once found a dozen or more examples in a decaying flower-stalk of Yucca ivhipplei, near Pomona in June. These latter were apparently the form described by Blaisdell as pervalida, and are easily separable from Arizona specimens of the typical yucateca, and it is not unlikely that Blaisdell's name will be restored to specific standing. H. cacti is abundant at San Diego in decaying cacti, and is fre- quently taken from beneath bark of decaying and water- soaked wood of the willow (Blaisdell); I have never seen 94 CALIFORNIA ACADEMY OF SCIENCES. the species near Los Angeles: vicina, common in decay- ing fruit of Cucurbita, also between the leaves and in the decaying flower-stalk of Yucca whiqppteii neglecta, rare, in decaying squashes; San Diego (Blaisdell); unknown to me: populnea, not common; one example, under bark, Riverside, May; more common in the desert portions of San Bernardino and San Diego counties. Hister. — H. sellatus, " not common, in spring and early summer flying about sandy places near streams; also found about the roots of plants" (Blaisdell); I have found it rarely in spring at Pasadena, and in small numbers under plants growing near the beach at Santa Monica, August: lucanus, Southern California (Horn): simplicipes, one example, San Diego County: sexstriatun, not common, occurring in early spring, fly- ing or resting beneath boards or about the roots of plants in grassy places; Riverside, Redondo, Pomona, San Diego: militaris, Yuma (Horn); in some seasons quite common, frequenting the sandy banks of streams; San Diego (Blaisdell): bimaculatus, one example found dead near a small stream, Riverside: lecontei, specimens in the Horn Collection from the southeastern portion of the State: punctiger, common under pine bark in the Sierras: remotus, recorded from Tejon (Horn): fracti- frons, Lake Tahoe: umbilicatus, Marin County: immunis, from " California," in Horn Collection. Tribalister. — T. marginellus, "rare, taken from beneath rocks in moist places" (Blaisdell);! cannot help thinking there is some mistake here, as marginellus is a rare east- ern species, the only examples known to me being the type described from Maryland, and a single example taken by myself in Rhode Island. Tribalus. — T. californicus is common under leaves and stones in moist places near water courses. COLEOPTERA OF SOUTHERN CALIFORNIA. 95 Epierus. — E. regularis, San Diego, San Bernardino: planulus, San Diego, Yuma (Horn): nasutus, Yunia, under cottonwood bark (Horn). All these are doubtless more common in the southeastern part of the State, and are probably all to be found under the bark of various trees, but especially cottonwood. Hetaerius. — No species of this genus is yet recorded from Southern California, but calif ornicus has been found at Sonoma, tristriatus at Calaveras, and morsus at Fort Tejon. Onthophilus. — 0. lecontei, very rare; three examples taken at Pasadena, in December, under rotten squash. Paromalus. — P. difficilis, Mojave (Horn); San Diego (Fuchs): mancus is described from Humboldt County by Casey. Carcinops. — C. 02mntice, not common at Pomona; more abundant in San Diego County and the southeast, in decaying Opuntia : tejonicus, a single specimen taken under pine bark in the San Bernardino Mountains: gilensis, one example, under chips on a freshly cut oak stump, Pomona; common in Arizona in decomposing cacti (Cereus): consors, said by Blaisdell to be common in decaying vegetable matter in San Diego County. A species found in numbers in decaying Yucca ivhipplei, near San Bernardino, was identified by Horn as consors, but a comparison with the type of this species makes this reference doubtful: tenellus, Colorado River, under bark. Casey mentions seeing a specimen of 14-striatus from Lake County, and I have recently seen the same species from Lower California; it will probably be found in our region. Anapleus. — A. marginatus, San Diego County. The species was described by Casey under the name compactus, but is considered identical with marginatus by authorities. 96 CALIFORNIA ACADEMY OF SCIENCES. Saprinus. — Numerous species inhabit Southern Cali- fornia, occurring in or about decomposing animal or vegetable matter. S. discoidalis, moderately frequent at Redondo beach, especially in spring; occurs also in Owens Valley and in Arizona: interstitialis , rare at Pomona, February to March; Catalina Island, and Placer County, early spring: pectoralis, not rare from the mountains to the sea, in early spring (February to March); there can scarcely be a doubt that behrensi is nothing more than an unusual form of pectoralis, in which the prosternal striae have become united in front. I have seen intermediate forms. S. obscurus occurs with pectoralis and is about equally common; they are cer- tainly very closely allied, if, indeed, they be distinct: pceminosus, moderately rare; Pomona, Ojai, Pasadena, San Diego: alienus, occurs only in the desert regions from Owens Valley to San Diego County: lugens, exces- sively abundant at times and always common, widely distributed: oregonensis, not rare; many localities: liti- colus, rather common on Redondo beach, December to April: scissus, common on sea beaches; I have never seen it inland: laridus, numerous examples taken on the beaches at Redondo and Santa Monica; Wickham re- ports it from Needles — possibly an error: insertus, two examples, Riverside, April: ciliatus, Colorado River, rare: vitiosus, found once at Yuma; occurs also in Owens Val- ley and is common in Arizona: lubricus, abundant everywhere: plenus, desert regions of the southeast: fimbriatus, very common and wide-spread: coerulescens, found once at Riverside in April, about decaying fish; Blaisdell says, "quite common in summer about the dead bodies of snakes and small animals," San Diego: intritus, San Diego (Casey): consobrinus, one example, Yuma, July; bigemmeus, common on all beaches; speci- mens received from Wickham are labeled Los Angeles: COLEOPTERA OF SOUTHERN CALIFORNIA. 97 estriatus, several examples taken near San Diego in the bed of the San Diego River, August; also on margin of salt pool at Santa Barbara, August: lucidulus, plentiful in the sand dunes at various beaches: propensus, San Diego (Casey): gaudens, San Diego, Ventura; uncom- mon on sea beaches: serrulatus, rare; sea beaches, Sari Diego, San Pedro: sulcifrons, common on beaches. The following species are also Californian: rotundatus, near San Francisco arid in Placer County (Van Dyke); cequipunctatus , ciliatus and vestilus, from near San Fran- cisco; lentus, Truckee; opacellus, northern. Plegaderus. — P. fraternus and P. nitidus are usually common under pine bark in the Sierras: consors I have seen labeled "San Diego County:" molestus, described from Lake Tahoe. Teretrius. — T. placitus, one example found flying early in March at Pasadena (Fenyes): ohliquulus has been taken at Santa Monica by Mr. Albright. Abraeus. — A. bolteri, San Bernardino (Le Conte). Bacanius. — B. globulinus, one example taken at Pasa- dena is thus referred; it is not typical, but as northern specimens show considerable variation, notably in the development of the elytral striae, it is likely that the differences shown are not specific. Acritus. — A. maritimus, rare, on sea beaches; San Diego and Santa Barbara: volitans, several specimens taken flying in the early evening; Pomona, August; others at electric light, Pasadena (Fenyes). . — &. basalis occurs near Yuma. August 1, 1901. 98 CALIFORNIA ACADEMY OF SCIENCES. Brachypterus. — B. troglodytes is occasionally numerous. on nettles; Pasadena, Pomona; April, May. Cercus. — G. sericans, plentiful on flowers of elder (Sambucus glaucus) throughout Southern California and the adjacent islands; very variable in size and color. Amartus. — A. tinctus and A. rufipes are found on flowers, in March; the former is the more common and has been taken most often from poppies (Eschscholtzia) . Athonaeus. — A. agavensis, San Diego and Los Angeles; on flowers of Agave. Carpophilus. — G. yucccv, Mojave desert, in unopened flower heads of yucca (Crotch): hi'mi/>ff,ru8t abundant: dimidiatus, decipiens and discoideus, less common, in decaying fruit in orchards; September to November: pallipennis, plentiful in cactus blooms in all localities: brachypterus , northern part of the State: niger, recorded from "California" (Santa Cruz, Fuchs). Colastus. — C. truncatus, frequent under bark of freshly cut trees; most specimens are of the form limbalis. Conotelus. — C. nt<'..rican.iix, southeastern California. Epuraea. — One example (a female) of a species near rufa was taken in the San Bernardino Mountains: ter- minalis was plentiful in the same locality under rubbish along streams: avara, one example, same locality: ovata, not common at Pomona, in decomposing mushrooms: February. According to Crotch, monogama occurs " throughout the Sierra Nevada, in a small white globu- lar fungus growing on dead pines, each fungus having a pair of the species." E. ambigua and E. truncatella are northern: a^tiva t I have taken on flowers at Lake Tahoe in July. COLEOPTERA OF SOUTHERN CALIFORNIA. 99 Nitidula. — N. ziczac, not very common at Pomona and in the southern Sierras, about dried animal remains, old bones, etc.; more common farther east. Omosita. — 0. discoidea,, not common, in decomposing organic matter, Pomona, San Bernardino Mountains. Perthalycra. — P. murrayi, San Francisco and north, also at Lake Tahoe (Fenyes). Several specimens taken in the San Bernardino Mountains are not quite typical but doubtless belong here. Pocadius. — P. dorsal-is, "California" (Ulke). Meligethes. — M. brassicce, common on willows in early spring; Pomona, Pasadena, Ventura, etc. Cybocephalus. — C. californicus is not rare on live-oak, taken by beating; Pomona, Pasadena. Cryptarcha. — C. concinna, one example, by sweeping near brook at Pasadena, August. Ips. — /. vitattus and /. cylindricus are northern. Pityophagus. — P. rufipennis, not common in the Sierras from San Bernardino north. Smicrips. — S. hypocoproides, Palm Springs (Hubbard). Rhizophagus. — R. scalpturatus , Placer County (Van Dyke). LATHRIDIIDJE. Holoparamecus. — H. kunzei, one example taken on the wing in the early evening, at Riverside, July; others have been taken in "Los Angeles County" by Coquil- lett: pacificm, one example, under bark of decaying log at Pomona, April; also taken by Coquillett in " Los Angeles County:" caularum, taken in flight, also under bark, by Dr. Fenyes, at Pasadena in February and again 100 CALIFORNIA ACADEMY OF SCIENCES. in September; found about grass roots at Palm Springs,, and in debris along the Colorado River by Mr. Hubbard. Dasycerus. — Specimens of angulicollis have been taken by Dr. Fenyes at Monterey, under the fungus- grown bark of a decaying stump. Metophthalmus. — M. rudis, Ojai Valley, Los Angeles > and Panamint Valley; specimens were taken by me in March at the former locality, occurring in the interior debris of a woody fungus: trux, one specimen taken on the under side of a log in a moist situation in the San Bernardino Mountains, July: parviceps, found in the region about and to the south (San Jose) of San Fran- cisco Bay. Lathridius. — L. armatulus, a rather common species in Southern California from the foot-hills of the Sierras to the coast and as far north as San Francisco, commonly obtained by beating and sweeping; it is not confined to any one plant, but I have taken it most commonly near Pomona on Solanum nigrum, in October and Novem- ber. L. costicollis is plentiful near San Francisco. Coninomus. — C. constrictus and C. australicus are not rare in our region and probably occur nearly every- where in the State; the former is a well known cosmo- politan species; the latter was described from Australia. C. nodifer has been taken in some numbers near San Francisco. Enicmus. — E. suspectus, Pomona; Panamint Moun- tains; not common: desertus, Palm Springs and Yuma (Hubbard): minutus, occurs everywhere, but is not com- mon in Southern California: crenatus, plentiful about the roots of herbage and in vegetable debris through- out Southern California: tenuicornis, Pomona, rare; COLEOPTERA OF SOUTHERN CALIFORNIA. 101 commoner further north: nigritus and ventralis have both been taken at Los Gatos and in the middle Sierras: sulcatulus bndfictus are Californian without more definite locality. Cartodere. — C. argus, several examples on drying yucca pith at Pomona: quadrifoveolata, a single specimen, Los Gatos. Revelieria. — R. californica was taken in company with Metophthalmus rudis, in woody fungus, Ojai Valley, March. I have seen specimens from "Los Angeles County" and Los Gatos. Corticaria. — The various species occur under bark, and are frequently taken on the wing at sunset or in the early evening, and occasionally come in numbers to electric lights. None of the species appear to be very abundant, but several would doubtless prove com- mon enough if properly looked for. I have seen specimens of planula from Pomona, Pasadena, Ojai Valley, and also from several locations in the central and northern part of the State; the majority of speci- mens have been taken flying, in early spring evenings. •C. serrata, C. elongata and (7. ferruginea are cosmopolitan species; a moderate number of the last two have been seen from Los Angeles County: serrata is apparently rare in this region: occidua and tenuipes have thus far occurred only in the Sierras, the latter being known only by the type, which was taken in the San Bernar- dino Mountains: inopia is known from the Tahoe region: prionodera is from the middle coast region. Melanophthalma. — The species of this genus occur on vegetation, and may usually be taken plentifully by beating and sweeping. M. casta has been taken at Pomona, Pasadena and Redondo, by sweeping weeds: 102 CALIFORNIA ACADEMY OF SCIENCES. simplex occurs on both sides of the mountains, but not very abundantly: insularis is known only from San Clemente Island: distinguenda, gibbosa and americana are all very common all over the State (I have not seen any gibbosa that were taken in the desert but it may occur there): incompta is represented by only two examples taken at electric light in Pasadena by Dr. Fenyes: similata is plentiful near the coast from San Diego to San Francisco: tenellais based upon two examples in the Le Conte Collection that were found at San Jose: villosa has occurred in the Lake Tahoe region ; other examples in the Horn and Le Conte collections are probably from the desert, though this is not certain. Fuchsina. — F. occulta, "Los Angeles County;" one example seen, collected probably by Coquillett. The specimen in my collection was taken by Mr. Fuchs in Mill Valley, near San Francisco, by sifting earth about the roots of a redwood. A specimen in the Hubbard and Schwarz Collection is labeled Los Gatos. TROGOSITID.K. Alindria. — A. teres is rare; found under Pine bark, San Bernardino Mountains. Trogosita. — T. vire.scens, not rare under bark through- out Southern California in and near towns; it is not un- usual under the loose layers of bark of eucalyptus: yucc desert region in the northeast; humeralis and elegans> northern coast region; estriatus, davicornis and parvi- collis, about San Francisco, the second named species being very abundant in the sand-dunes on the ocean front; dentipes, common to the south of San Francisco; prominens, San Luis Obispo County; granulata, granosa and cuneaticollis , exact locality not named, though it ia probable that the first two occupy the desert region of the northeast and possibly come as far south as Owens Valley; cordata, middle region, from San Francisco to Lake Tahoe, also ranging both north and south of this- latitude in the central valley; scabricula, Sacramento and Lake Tahoe. Embaphion. — E. depressum, Vallecito (Le Conte). Trogloderus. — T.costatus, San Diego County (Fuchs). Eulabis. — E. grossa is not rare on San Clemen te Island, and has also been taken on Santa Barbara and COLEOPTERA OF SOUTHERN CALIFORNIA. San Nicolas islands: rufipes, pubescens and laticornis are more or less common from San Diego north through the western portions of our district, especially under stones and rubbish in dry places in spring: crassicornis is described from "So. Gal.," and must resemble the preceding in habits: obscura is plentiful along the sea beaches: bicarinata occurs in the San Joaquin Valley. Cerenopus. — C. concolor and C. costulatus are taken in the Colorado Desert; the former is moderately common at Palm Springs, the latter is said by Blaisdell to be rare in San Diego County. Argoporis. — A. costipennis and A. bicolor, Colorado Desert: inconstans, San Diego (Horn). Amphidora. — A. littoralis is common everywhere west of the mountains; found beneath logs, rocks, bark, etc.; as remarked by Blaisdell, the name is not at all appropriate: nigropilosa occurs along the seashore and may usually be found in numbers about the roots of plants on and adjacent to the sand-dunes, or concealed beneath any object that will offer shelter. Cratidus. — G. osculans is common and widely diffused: fuscipilosus occurs, according to Blaisdell, on the sum- mits of the mountains about Julian; it is, perhaps, not specifically distinct from the preceding. Stenotrichus. — 8. rufipes, San Diego, Riverside, Po- mona, Santa Monica; not very common. Alobates. — A. pennsylvanicus is northern. Iphthimus. — I. serratus and its variety, sublcevis, occur under bark, in the Sierras; the latter has been taken in the San Bernardino Mountains. Ccelocnemis. — G. dilaticollis is found in the higher parts of the southern Sierras, under bark, logs, etc.: 170 CALIFORNIA ACADEMY OF SCIENCES. obesa is not rare in the foot-hills near Pomona, Pasadena, etc.: magna, Central Valley: rugosa, Los Angeles County (Coquillett). Centronopus. — C. parallelus, middle Sierras, under bark. Cibdelis. — C. blaschkii, San Diego County, "mountain- ous districts, under bark " (Blaisdell); commoner far- ther north: bachei, Santa Barbara, San Clemente and Santa Catalina islands: Icevigata, Santa Barbara. Tenebrio. — Specimens of obscurus have been found in grain at Pasadena; perhaps a mere sporadic importa- tion: tenebrioides is rare, under bark, in the San Bernar- dino Mountains. Bius. — One example of estriatus was found under pine bark in the San Bernardino Mountains, July; it is one of our rarest species. Doliema. — D. plana is generally rare, but is occasion- ally found in large numbers under the bark of dead sycamores; I have taken it thus in the Ojai Valley, in March, and Blaisdell reports similar captures in San Diego County; occurs also at Yuma (Wickharn). Alaephus. — A. pallidus, Palm Springs (Fenyes), Fort Tejon (Horn). Mr. Wickharn reports a species of Alcephus " near pallidus " from Needles, on the Colorado River. Eupsophus. — E. castaneus, Palm Springs, not rare in spring; Owens Valley, flying by night (Horn). Mecysmus. — M. angustus is found rather abundantly flying at night at Yuma (Horn), Mojave Desert, Pomona and Riverside; under stones and on sidewalks at the latter places (never on the wing in my experience): tennis is described from "So. Cal." COLEOPTERA OF SOUTHERN CALIFORNIA. 171 Trichoton. — T. sordidum occurs at Palm Springs, in April, under boards, stones, etc., as is generally true of the Blapstini. Ulus. — U. crassus is common in many localities: latus, along the San Diego River (Blaisdell). Blapstinus. — B. longulus, Yuma, San Diego (Blais- dell): validus, "So. Gal." (Casey); probably from the Colorado Desert: dilatatus, common everywhere: histri- cus, Los Angeles County (Newhall): coronadensis , rather common at Coronado (Blaisdell): rufipes, our common- est species: cequcdis, San Bernardino: funebris, South- ern California (Casey): brevicollis, Riverside, Santa Monica, Pomona; not very abundant: pubescens, San Bernardino, Pomona, San Diego: sulcatus, Riverside, San Diego, Ojai Valley; rather common. The follow- ing species are described from the middle and northern parts of the State; their identification is a matter of much difficulty: fulginosus, discolor, gregalis, pulveru- lentus, parallelus, and inquisitus. Conibius. — G. parallelus is said by Blaisdell to be rather common about San Diego and Poway, but I have not yet detected it in the vicinity of Los Angeles; it was described from San Jose: seriatus is common in Los Angeles County, and occurs as far north as Sylvariia; it was described from the Colorado Desert. The distinct- ness of this and the preceding species I believe may fairly be questioned. C. elongatus is said by Horn to be rather common under stones, in Owens Valley: crassipes is described by Casey from " So. Gal." Notibius. — N. puberulus, Colorado Desert, Needles (Wickham), not rare at Palm Springs in April: puncti- collis, rather frequent at Riverside, Pomona, and Pasa- dena; often seen on city streets and walks: granulatus, 172 CALIFORNIA ACADEMY OF SCIENCES. Palm Springs, Yuma: gracilis, Indio (Casey): sulcatus, Riverside, San Diego, San Cleinente Island; not common. Cnemeplatia . — C. sericea is generally rare; it was once taken in some numbers, under boards, amid stable refuse at Pomona; it is occasionally taken on the wing toward evening, and at San Francisco comes to electric lights, at times in great numbers. Horn speaks of the species as being rare in Owens Valley, under stones. Alaudes. — A. singularis is a very rare species origi- nally taken by Dr. Horn in Owens Valley, where it was found living under stones, with a small black ant. A few specimens were next taken by Wickham — some twenty-five years later — in eastern Oregon, then a single example by Koebele, in the Argus Mountains of southeastern California, not far south of the original habitat. In November and December of 1893 and 1895, I secured about a dozen examples from under boards in my garden at Pomona, under conditions which apparently indicated no connection with ants; and since then Dr. Fenyes has taken about an equal number at Azusa, Los Angeles County, this time with ants. I know of no other instances of its capture. Tribolium. — T. ferrugineum and T. confusum are both found in ground cereals, the former being less common in my experience. Blaisdell speaks of ferrugineum as being rare, under the bark of trees, at San Diego. Phthora. — P. americana occurs at Lake Tahoe. Gnathocerus. — G. cornutus occurs with Tribolium in ground cereals. Echocerus. — Several specimens of maxillosus have been taken at Pasadena in March. COLEOPTERA OF SOUTHERN CALIFORNIA. 173 Ulosonia. — U. marginata occurs along the Colorado Kiver, under cottonwood bark. Merotemnus. — M. elongatus labeled " Gal." is prob- ably from the southeast. Aphanotus. — A. brevicornis is rather common in the eastern portion of San Diego County (Blaisdell); very rare at Pomona, a single dead specimen being all that I secured in seven years' collecting. Alphitobius. — A. ovatus and A. piceus have both found their way into our territory, though neither is as yet common. Of the former species, I secured a specimen under bark at Indio, in the Colorado Desert, and several examples of the latter have been taken at Pasadena by Dr. Fenyes. Cynaeus. — G. angustus is reported from the Colorado Desert: depressus is rather common in and upon the de- caying base and roots of Yucca ivhipplei in various local- ities; I have found it near Pomona in May. Metaclisa. — M. marginalia is rather rare, occurring under bark of pines in the San Bernardino Mountains; also found at Julian (San Diego County). Uloma. — U. longula is not rare under bark, in the Sierras. Phaleria. — P. rotundata is very abundant everywhere on our seacoast from San Diego to San Francisco, oc- curring beneath kelp. I have no hesitation in uniting limbalis with the preceding; a long series shows every grade in coloration from uniform testaceous to typical limbalis, which is in great part black; a precisely analo- gous variation is observable in the common testacea of the Atlantic coast. P. debilis is reported from Yuma: 174 CALIFORNIA ACADEMY OF SCIENCES. globosa is common on the seashore, near San Francisco: kumeralis is said to be from " Cal." Anemia. — A. calif ornica, Owens Valley. Platydema. — P. subquadratum, Colorado River. Mr. Wickham reports it as not rare in August at East Bridge, just across the river from Needles. P. oregonensis is rather common about fungus on old stumps, under bark, etc., in the Sierras from San Diego County north. Alphitophagus. — A. bifasciatus is not especially un- common of late at Pasadena and in the neighboring mountains. Hypophlceus. — H. substriatus occurs in the Sierras, under bark: opaculus is very scarce; two examples were taken in March from the burrows of Monarthrum scutel- lare, in live-oak. Pentaphyllus, — P. californicus is northern. Eleates — E. explanatus and E. occidentalis both occur on fungus growing on logs in the region about Lake Tahoe; the former also inhabits the forests to the north- ward of San Francisco. Megeleates. — M. sequoiarum, middle Sierras — Lake Tahoe and Calaveras. The larva has been taken by Dr. Blaisdell in a species of woody fungus, and has been de- scribed by Wickham. Apocrypha. — A. anthicoides, Pomona, Pasadena, San Diego; uncommon. All specimens seen have been taken in early spring. Dr. Fenyes once found it associated with ants, but perhaps accidentally, as this habit has not been elsewhere noticed. A. dyschirioides is said by Blaisdell to occur rarely near San Diego: divinoides is found in Owens Valley. COLEOPTERA OF SOUTHERN CALIFORNIA. 175 Helops. — H. edwardsii is not rare, under bark, in the San Bernardino Mountains: ovipennis, Mojave Des- ert: rugicollis, Owens Valley and Tejon: strigicollis, " So. Gal.," probably near San Diego (Horn): attenuatus, Val- lecito (Colorado Desert) and Owens Valley. H. bachei and H. blaisdelli are said by Blaisdell to occur under mari- time plants growing on the sand-dunes near San Diego, and one of these or a closely allied species I have found very common in similar situations at Redondo Beach; bachei was described from the Santa Barbara Islands, and typical examples are perhaps found only on the islands: discipula is described from the vicinity of San Diego. The following species are more northern: opacus> San Francisco and north, also Sacramento; punctatus, "Gal.;" rugulosus, San Francisco; angustus, Tejon ; californicus, San Jose, Lake Tahoe (beaten from pines in July); tumescens, "Gal., Coll. of Ulke." ^GIALITID^E. ^)gialites. — The exact locality of californicus is not stated; it is doubtless northern, if really from the State: fuchsii has been obtained in some numbers from Mendo- cino County and Farallon Islands, by Mr. Fuchs. CISTELID.E. Xystropus. — Horn expresses a belief, which I think well founded, that X. californicus is an accidental im- portation from Mexico or further south. The original specimen was found at Martinez, on the shore of San Francisco Bay, and has never since been duplicated. Stenochidus. — I have taken specimens that are refer- able to gracilis and cyanescens, at Pomona and Pasa- dena, during May and June, but have not yet succeeded 176 CALIFORNIA ACADEMY OF SCIENCES. in separating them to my satisfaction. It is certain that the color of the legs is not a specific character, these being usually red in the males and black in the females. Hymenorus. — H. infuscatus, Los Angeles, Pomona, June; Catalina Island, July: grandicollis, specimens occurring at light on Echo Mountain were so identified by Casey; a different species in the collection of Dr. Fenyes, and taken at Palm Springs, fits the description of grandicollis still better: fusicornis, Riverside and Pasadena, April and May; rare: fusculus, Coronado, in decaying sunflower blossoms (Blaisdell): macer, Poway, common, (Blaisdell): punclatissimus, Riverside, Po- mona; June to October; not rare. Blaisdell reports inquilinus as occurring in the nests of the agricultural ant, in Calaveras County, in September. H. punctula- lus, H. discrepans, and H. uniseriatus are Calif ornian, but without definite locality. Mycetochares. — M. longipennis is rare at Pasadena, March (Fenyes): procera, Los Angeles (Casey); Pasa- dena, April (Fenyes): pubipennis, Pasadena and Re- dondo, March. All the above are more or less rare. M. nevadensis I have beaten from pines at Lake Tahoe, in July: crassulipes and pacifica are also described by Casey from California, the former from Humboldt County, the latter without precise locality. Isomira. — 1. variabilis is exceedingly common on ilowers, especially of greasewood, in the foot-hills, and up to moderate elevations in the Sierras; it occurs also on Catalina Island and is probably found throughout the region to the west of the mountains. 1. luscitiosa is also quite common in the Sierras, in company with the preceding: monticola is described from Lake Tahoe, COLEOPTERA OF SOUTHERN CALIFORNIA. 177 and discolor from " Gal." Hopping alludes to the lat- ter as being common at from 1,000 to 7,000 feet eleva- tion along the Kaweah River, in Tulare County. Cistela. — C. opaca is common on flowers in the south- ern Sierras from April to June. The color of the legs is not a specific character, the femora being about as often red as black. The specimens taken by Blaisdell in San Diego County and referred to theveneti, are doubtless the red-legged form of opaca, theveneti occur- ring in the middle Sierras, so far as known. OTHNIID^E. Othnius. — 0. longicornis, Yuma. MONOMMIDJS. Hyporhagus. — H. gilensis, San Bernardino County (Fuchs). MELANDRYIDJE. Carebara. — C. longula is rather plentiful on pines, in the San Bernardino Mountains, in July. Phloeotrya. — P. river si, P. bicincta, and P. vaudoueri are all northern, the two former being from Sonoma County. Eustrophus. — E. repandus is from the extreme north. Nothus. — N". luteus, Pomona and Pasadena in June; taken on oaks. Lacconotus. — L. pinicolus, Pomona and Pasadena; rare during May and June; found always on oaks, not- withstanding its name. 12 September 22, 1901. 178 CALIFORNIA ACADEMY OF SCIENCES. Mycterus. — M. concoLor is not rare in the San Bernar- dino and other ranges of the southern Sierras, in June and July; the variety flavipennis occurs rarely with the type: quadricollis is said by Crotch to occur on flowers of Agave, at Temescal: canescens is found also in the Sierras, but farther north. PYTHID^E. Priognathus. — P. monilicornis, Tallac (Lake Tahoe), under bark (Fenyes). Cononotus. — G. macer, Owens Valley: punctatus, San Jose: sericans, San Jose and San Diego. Salpingus. — 8. alternatus is northern. Rhinosimus. — R. ceneirostris, about San Francisco. (EDEMERID^E. Calopus. — C. angustus, "Cal.," probably northern. Ditylus. — D. quadricollis, from the northern and middle Sierras. Nacerdes. — N. melanurus, Long Beach; a single dead specimen washed up by the waves. I have not thought it wise to place this species in the foregoing list on so slender a basis. Xanthochroa. — X. calif ornica, middle Sierras: cen- tralis, Sylvania (Ricksecker): 'marina, Marin County. Copidita. — C. quadrimaculata is rather common, un- der rubbish along the sea beaches at Santa Monica and San Francisco: bicolor is northern: cyanipennis, "Coast Range below San Francisco." Asclera. — A. nigra, San Bernardino County: excavata, foot-hills near Pomona, April and May: discolor is northern. Chrysanthia. — C. repanda, Yuma. COLEOPTERA OF SOUTHERN CALIFORNIA. 179 Oxacis. — O.fragilis, San Diego: bicolor, not rare on the wing at dusk in the San Bernardino Mountains, alti- tude 5,000 feet: 0. sericea, Owens Valley: lucana and debilis are from Yuma. Rhinoplatia. — R. ruficollis, Owens Valley. CEPHALOID.E. Cephaloon. — C. tenuicorne, northern: bicolor, Sonoma and Placer counties. Drachylis.— D. simulans was recently described by Casey from Placer County. MORDELLID^. Pentaria. — P. nubila is abundant everywhere: hirsuta, Southern California: pusio, common and widely dis- persed, frequently beaten from oaks, but nearly always obtainable by promiscuous beating and sweeping; this species has been wrongly included with Anaspis. Anaspis. — A. atra and A. collaris are both frequent on flowers, though the former is more plentiful farther north: militaris and sericea are quoted from " Gal.," but I am unable to ascertain precise localities. Two specimens of an undescribed species were taken by me in the San Bernardino Mountains, in July. Mordella. — M. scutellaris is very common and widely dispersed; it is extremely variable in size. A single specimen of an undescribed species was secured at Po- mona some years ago. Mordellistena. — The species of this genus are rather numerous in our district and many are undescribed. The greater number are black without ornamentation and will prove difficult to define. The following are 180 CALIFORNIA ACADEMY OF SCIENCES. now credited to the State: vilis, San Diego, Los Ange- les, etc., common; comata, San Diego; aspersa, San Diego (teste Smith); tosta, Yuma (Horn); nubila, San Diego (Le Conte), Riverside, one example identified by Smith; unicolor, Pomona, not common; injima and cequalis also inhabit the State according to Smith. ANTHICID.E. In a recent revision of this family Casey has estab- lished a large number of new genera, especially for the reception of the species now included under Anthicus and Xylophilus. It may be that some of these will stand but the writer is convinced that many of them will not, and until proper discrimination is possible, it has seemed best to employ the genera recognized by Le Conte and Horn in the " Classification." Eurygenius. — E. constrictus is not very common; it is taken by beating and sweeping, in the foot-hills near Pomona and Pasadena, during May and June. Stereopalpus. — 8. pruinosus is moderately common on willows, near Pomona, in June: nimius and incanus are described from " So. Cal." and Los Angeles County, re- spectively: variipes, indutus, and impreesicollis are de- scribed from the northern part of the State. Corphyra. — C. distinguenda is not rare, Pomona dur- ing April and May: bardii, Ventura, Santa Barbara, Pasadena; not common: inconspicua, Riverside, Po- mona, Pasadena; not rare. The males of all these species are much rarer than the females, and as the lat- ter sex are mutually nearly indistinguishable in many cases, it is quite likely that we shall find other species are inhabitants of our territory when the males are known. The following species are also California!!: COLEOPTERA OF SOUTHERN CALIFORNIA. 181 ftabellata, Lake Tahoe and north; crotchii, middle coast region; abnormis, Lake Tahoe; funebris, " widely dif- fused in Cal.;" punctulata, middle and northern; lewisii var. monticola, "Cal.;" vittata, "Cal." Formicomus. — F. mundus is found under rubbish along the banks of the Colorado River, at Yuma, in July. Anthicus. — A. tennis is not uncommon at Yuma, in similar situations to the preceding: pinalicus, canon- icu8t bipartitus, and turgidicollis belong to the genus Lappus of Casey; they are arboreal in habit, canonicus being an especially abundant species in the foot-hills above Pomona, Pasadena, etc., occurring on many trees and shrubs. Specimens taken at Arrowhead Springs are referred with some doubt to pinalicus: bipartitus oc- curs at Yuma: turgidicollis is from "So. Cal.:" cali- fornicus is widely diffused, being known to me from Santa Monica, Long Beach, Riverside, Santa Catalina and San Clemente islands, Bakersfield and San Francisco: con- Jinis is plentiful throughout our district; it is found about the roots of grass, on the borders of lawns, and often comes to light: formicarius is not frequent; I have seen specimens from Pomona and Pasadena, the only specimens taken by me being found in stable refuse: rufulus occurs at San Diego (Le Conte): cribratus, Riverside and Pomona, in May and June; not common: hecate, margins of streams, in the foot-hills near Po- mona: luteolus, common along the Colorado River: pinguescens, common and widely dispersed from South- ern California to the Columbia River: ovicollis, Los An- geles (Casey): biguttulus, Riverside, May and June; also middle California and Vancouver: punctulatus, abun- dant and widely dispersed in the true Pacific region: $eminotatus, Los Angeles and Kern counties: nanus, San 182 CALIFORNIA ACADEMY OF SCIENCES. Diego (Le Conte): obliquus, very common in Los An- geles County, coming often to light in swarms during May and June: militaris, mountains near Pomona, but not common: bdlulus, Pasadena in March and San Diego; not common: herifuga, San Bernardino, Riverside, Po- mona, Pasadena, etc.; rather common: maritimus, not abundant on the sea beaches; Long Beach, June: cor- ticalis, Yurna: obesus is rather plentiful, and in much variety of size and color; various beaches of Southern California and at San Francisco. A. albicans and A. parviceps are merely varieties which would occur in any considerable series taken at any one locality. The following are either from the middle or northern regions- or are mentioned without definite locality: vigilans,. nitidulus, franciscanus, nigritulus, protectus, mercurialis, prceceps, auriger, inscitus, amwnus, obscurellus and helvinus. Tanarthrus. — The writer has not yet met with salinus, which is said to occur around the southern salt lakes: alutaceus is not rare at San Diego and Redondo; I have taken specimens at the latter locality in March and April, on the muddy border of a small salt lake. Notoxus. — N. spatulifer, Los Angeles County (Casey): denudatus, rare, Pomona and Los Angeles: debilitans^. San Diego: conformis, Southern California (Horn): sparsus, not rare in the foot-hills near Pomona: con- strictus, exceedingly abundant nearly everywhere: ro- bustus, Los Angeles County: alamedcv, at times plentiful on the sand beneath and about the roots of plants, above the beach at Redondo: cavicornis, rare; found under bark and on the wing, at Pomona, in November and December: calcaratus , common and widely dispersed in COLEOPTERA OF SOUTHERN CALIFORNIA. 183 our region: lustrellus is described from San Francisco: humboldti, described from Hurnboldt County: nevadensis has been found at Tallac, by Dr. Fenyes: serratus and apicalis are both credited to California by Dr. Horn, but there is reason to suspect that his specimens were not properly referred. Three other species of doubtful standing, but probably undescribed, are known to me from Southern California. Mecynotarsus. — M. delicatulus, Yuma and Pasadena, April; several examples taken at electric light. Xylophilus. — X. brunnipennis is not common; I have seen examples from San Bernardino, Pomona, and Pasadena. This is the species described by Casey as saginatus, but there appears to be no need for a new name. X. brunnescens , X . nucleus and X. constrictus are known only from one or two specimens each, and all are from the higher parts of the southern Sierras; constrictus has also been found at Lake Tahoe. PYROCHROID.E. Pyrochroa. — P. californica was recently described by Dr. Horn, from specimens taken in Los Angeles County by Coquillett; it is undoubtedly a rare insect. Cysteodemus. — C. armatus occurs at many places on the Colorado Desert; taken in numbers at Yuma, in March, by Mr. Daggett. Meloe. — M.barbarus, Santa Barbara Islands (Le Conte): strigulosus, a specimen so referred was taken by me at Palm Springs: opacus is northern. Nomaspis. — N. sublcevis, from Fort Tejon. 184 CALIFORNIA ACADEMY OF SCIENCES. Poreospasta. — P. polita, from "Southern Coast Range of Gal." (Gabb). Nemognatha. — The species of this genus are moder- ately numerous on flowers, chiefly Composite, from June until October. There is much variation within specific limits, which renders the proper separation of species difficult. N. apicalis and N. dubia are common on sun- flowers, in September, at Pomona, Pasadena, etc.; two undescribed species occur with them, but more spar- ingly: lutea probably inhabits the Colorado Desert, but I have not yet recognized specimens with certainty: nigripennis is not common; I have seen specimens from Los Angeles, Pomona (May), and the San Bernardino Mountains (5,000 feet elevation), July: scutellaris is very common on low Composite, near Pomona, Pasadena, etc., in June and July: dichroa and piezata are reported from the State, but I have been unable to determine the exact localities. Gnathium. — G. nitidum, Owens Valley. Zonitis. — One example from Barstow is referred to flavida. I have seen a specimen in Dr. Van Dyke's collection of an apparently undescribed species from Southern California. Epicauta. — I have specimens of alphonsii said to have been collected at or near San Diego; the species was described from Mariposa County: puncticollis, oblita, and straba are found on flowers in the foot-hills in Los Angeles County, from September to November; the first is always common, the second rare, the last is rather rare, though occasionally met with in abundance: fallax is found in Owens Valley: maura, San Diego: niaculata, though no locality is named, doubtless occurs only in the deserts of the east or southeast. COLEOPTERA OF SOUTHERN CALIFORNIA. 185 Cantharis. — Three examples of melcena in my collec- tion are from Southern California, one from Temescal, the other two without definite locality: magister, Colo- rado River, Owens Valley: vulnerata, common at times at Pomona and Pasadena, on flowers, in September; Owens Valley (Horn): childii, near Los Angeles, April (Van Dyke); in Composite; San Diego (Horn): tenebrosa, San Diego; Arrowhead Springs, April: mcerens, Santa Mon- ica, Owens Valley, Tejon, Sacramento: insperata, Mojave Desert and San Diego, in April: occipitalis and incom- moda are recorded from "So. Cal.:" stygica, San Ber- nardino Mountains, at an altitude of 6,000 feet; 4 ' Oregon to the borders of the Colorado Desert:" auriculata, Riverside, Pomona, Pasadena, etc., not rare, on low Compositee, in early spring: ceneipennis, found in the same localities and at the same time as the pre- ceding: crotchii, San Diego, March: nitidicollis , Pasa- dena, Riverside, San Diego in May; rare at the former places, more common at San Diego: lugens, not common at Pomona and San Diego in May: compressicornis , Owens Valley; Los Angeles County (Van Dyke): cyani- pennis, refulgens and rathvoni are found in middle Cali- fornia: ulkei is recorded simply from ''Cal." Calospasta. — C. elegans, Cariso Creek, western part of Colorado Desert, in San Diego County: perpulchra, rather rare on flowers, Pomona, in August and Septem- ber: mirabilis, desert regions of Los Angeles and San Diego counties: mces^a, Southern California, exact local- ity not known: nemognathoides, Owens Valley and Yuma: opaca, desert or semidesert regions near Los Angeles: fulleri is simply reported from "Cal." but is probably, like nearly all the species of the genus, from the deserts of the east or southeast. 186 CALIFORNIA ACADEMY OF SCIENCES. Tegrodera. — T. erosa, San Diego, Riverside, Owens Valley (race latecincta). Certainly very rare at River- side, but common enough at times at various places on the Desert. Horn states that it occurs in Owens Valley in "the latter part of June, on a low plant bearing blue flowers. " Phodaga. — P. alticeps, Indio, Owens Valley. RHIPIPHORID^E. Rhipiphorus. — R.flavipennis and R. cruentus are rather uncommon, on flowers in the southern Sierras, at an altitude from 1,500 to 5,000 feet; I have taken them in the San Gabriel and San Bernardino ranges; var. rufus of the latter species has occurred at Los Angeles (Fuchs). Myodites. — M. californicus, Los Angeles County (Van Dyke). RHINOMACERID^E. Rhinomacer. — R. comptus and R. bombifrons occur on conifers, in the Lake Tahoe region: pilosus is described from "Cal." Diodyrhynchus. — D. byturoides is found in the middle Sierras (Placer County). RHYNCHITID.E. Auletes. — A. nasalis is found near San Diego, also in Los Angeles County; not common: lalifrons, Southern California (Casey). Rhynchites. — R. bicolor, Pasadena, May; San Bernar- dino Mountains, August; common wherever wild roses occur: aureus, Riverside, San Diego, and Ojai Valley, from February to May; San Clemente Island, June 1. A blue variety, supposedly of this species, has been taken in the San Bernardino Mountains. R. ceratoides COLEOPTERA OF SOUTHERN CALIFORNIA. 187 is abundant on Eriogonum cinereum, at Redondo, in April and May; it has also been found in the foot-hills near Pomona, but on what plant I am not now able to say: velatus occurs in the " Sierra Nevada Mts. — Mor- rison:" naso is described from " Gal." Deporaus. — D. glastinus is common on live-oaks,, especially when in blossom, throughout our region. OTIORHYNCHID.E. Minyomerus. — M. languidus, Fort Tejon (Horn). Stamoderes. — S. uniformis, Sonoma County. Agasphaerops. — A. nigra, Mendocino County. Trigonoscuta. — T. pilosa is abundant throughout the year in the sand-dunes along the ocean front. Eupagoderes. — E. argentatus, E. desertus and E. varius inhabit the Colorado Desert, while geminatus and plum- beus occur farther north, in Owens Valley. It is almost certain that plumbeus is not distinct from varius. Spec- imens of a species of this genus have been found at Claremont, by Professor A. J. Cook; these are possibly vurius, but so far as seen they are uniformly vittate and I am inclined to believe them different from anything described. Rhigopsis. — R. effracta is common on and about the roots of various weeds, at Pomona, Pasadena, San Ber- nardino, etc. Horn reports it as having been found "feeding on yucca.'7 Amotus. — One example of gracilior was found on the beach at Santa Barbara, in February; it is not rare at Santa Monica (Albright): longisternus seems very close to the preceding, and like it was described from Los Angeles County. 188 CALIFORNIA ACADEMY OF SCIENCES. Dyslobus. — D. signis is found only in the most north- ern parts of the State. Amnesia. — A. tumida, Santa Cruz Mountains: rauca, decidua, elongata, and tesselata, from the vicinity of San Francisco: sculptilis, discors, and granulala, from the -extreme north: decorata, middle Sierras. Adaleres. — A. ovipennis and A. humeralis are quite -common on live-oaks, especially in early spring. The differences named by Casey seem illusory and intercur- rent in a large series. Nomidius. — N. abruptus, "California." Orimodema. — 0. protracta, Mojave Desert (Horn). Nocheles. — N. vestitus, Lake Tahoe (Fenyes). Mimetes. — M. setulosus, San Diego, April to June; Ventura: seniculus is probably from farther north, but the exact locality is not known to me. Phymatinus. — P. gemmatus, "Cal. and Oreg." Miloderes. — M. setosus, Kern County. Sciopithes. — Specimens taken on San Clernente Island in June are identified by Casey as 8. setosus, var. ; the species was described from north of San Francisco (Marin and Napa counties). 8. obscurus occurs from San Francisco north, and is quite common; significans , brumalis, arcuatus, and angustulus are described by Casey from the same region. Agronus. — A. cinerarius is abundant on conifers, at Lake Tahoe: deciduus, San Francisco. Paraptochus. — P. sellatus, foot-hills near Pomona, in June. COLEOPTERA OF SOUTHERN CALIFORNIA. 189 Stenoptochus. — 8. inconstans, Riverside and Pasa- dena; swept from weeds* in April and May. Orthoptochus. — 0. squamiger, "Cal." Mylacus. — M. saccatus is northern. Thricolepis. — T. inornata is not rare in the San Ber- nardino Mountains, in July: simulator is described from Fort Tejon. Peritelopsis. — P. globiventris, central California. Peritelodes. — P. obtectus, Monterey County. Peritelinus. — P. variegatus, Lake Tahoe. Geoderces. — One example of puncticollis was taken at Pomona, in February. Two undescribed species, one of them quite common, have been taken at Pomona and Pasadena. G. incomptus occurs from San Francisco north. Geodercodes. — G. latipennis, Monterey, in June. (Casey and Fenyes). Aragnomus. — A. griseus, Tulare County: hispidulus, Los Angeles County. Dysticheus. — D. insignis, Southern California (Horn). Eucyllus. — E. vagans, from the southeast. Thinoxenus. — T. squalens, "Not rare near the seacoast of California." Rhypodes. — R. dilatatus, "near the seacoast at San Diego." I have an example taken near Pomona in June. Panormus. — P. setosus, Monterey County. Dirotognathus. — D. sordidus, Fort Mojave (Crotch). Elissa. — E. constricta, Yuma. 190 CALIFORNIA ACADEMY OF SCIENCES. Aramigus. — A. fulleri is rapidly spreading through- out Southern California and attacking a variety of trees and shrubs. I have found the beetles from September to November, most frequently on rose bushes. Scythropus. — 8. californicus is an abundant species in the middle Sierras. Specimens taken on pines in the San Bernardino Mountains are probably distinct, but &re left here for the present: lateralis is described from Lake County, ferrugineus from Marin County, cinereus from Lake Tahoe. CURCULIONID.E. Sitones. — 8. sordidus, "San Francisco and San Diego;" it is unknown to the writer: crinitus, one example taken at Pomona is so referred: nebulosus, one example, Pomona, July: hispidiceps is the commonest species in the vicinity of Los Angeles; identified by Capt. Casey, who writes that his prominens and angustulus are to be considered synonymous with this species: explicitus, not rare at San Diego in February. I have taken one spec- imen of a very distinct and undescribed species in the San Bernardino Mountains in July. The following are credited to the State, but their recognition is practically impossible as our literature now stands: californicus, 4t Cal. and Oreg.;" vittatus, San Francisco; varians, sparsus and osculans, Humboldt County; margaritosus, Santa Cruz and Monterey; procerus, Napa; occidentalis , Sonoma; montanus, Placer County; alternans, "Cal.;" apacheanus, "So. Cal. or Ariz." Triglyphus. — T. ater, middle Sierras: a fine species which appears to be decidedly rare. Apion. — A. pennsylvanicum is one of our rarer species, occurring at Pasadena in May and August; it is widely COLEOPTERA OF SOUTHERN CALIFORNIA. 191 diffused throughout the United States, but much more common in the Atlantic district: hesperum has been found only by Coquillett in the desert portions of Los Angeles County: sordidum is an abundant species in the desert but very uncommon west of the mountains; specimens have been taken in May at Pomona and Pasadena; it has been bred from galls on several occa- sions— notably by Mr. Koebele from "Cecidomyid and dipterous galls on Artemisia calif arnica/' and by Mr. Schwarz from " bud-like gall on stems of Hymenoclea monogyra in Arizona: antennatum is not rare, on pines in both the southern and middle Sierras, July; taken also at Pomona in January, Catalina in July, and Ven- tura in March: cedorhynchum is common throughout our region, April to October: opacicolle, Ojai Valley, March; uncommon: troglodytes is plentiful from San Diego to San Francisco, December to May: proclive is abundant nearly everywhere both east and west of the mountains; it has been beaten from willows at Pomona, March to October: cribricolle is widely distributed throughout the State, and is generally abundant; common on Eriogo- num cinereum at Redondo in Spring, but occurs on a variety of plants and trees. A. cordatum is rare at Pomona, where specimens have been beaten from willows in October: varicorne is plentiful at Yuma, in July, on a species of Dalea: ventricosum is very abundant on the desert, occurring on mesquite: attenuatum is rather rare; specimens have been taken at Pomona, Pasadena and Riverside. Two other species — protensum and walshii — have been found within the State; the former is known by the unique type taken at San Francisco, while the latter has been found only in the north. Podapion. — P. gallicola, middle and northern Sierras; not common. Lepyrus. — L. perforatus is northern. 192 CALIFORNIA ACADEMY OF SCIENCES. Listronotus. — Two undescribed species of this genus are known from our district. One of these is near tere- tirostris; it has been taken at San Diego, Pomona, and Antelope Valley. Of the second species, a small form near gracilis, one example only has been found by me at Long Beach . Macrops. — M. hyperodes and M. californicus are known from the central or northern parts of the State. Emphyastes. — E. fucicola is not uncommon along the sea beaches, beneath sea-weed, etc. Lixus. — L. asper, not frequent at San Bernardino, on Rumex (Wright): perforatus, not rare at Pomona, March to June: semivittatus, specimens which do not appear to differ from typical Arizona examples of this species are not rare on and about the roots of a plant growing along the sand-dunes near the beach at Santa Mon- ica: auctus is northern: parcus is described from San Francisco. Dinocleus. — One specimen of pilosus found at Coro- nado in July is scarcely different from the Le Conte type. The type is without exact locality but is doubt- less from the south, and probably from the same region. D. jacobinus is described by Casey from San Diego: farctus, from "near the southern boundary:" albovesti- tus is not rare near Los Angeles in August and Septem- ber: molitor is common on the desert at Indio and Yuma: wickhami was taken by Mr. Wickham at Indio. Cleonus. — C. inornatus, Owens Valley: jxicificus, one example at Redondo in April, on Astragalus crotalarce: erysimi, not rare at Redondo on flowers of Erysimum asperum, March and April: lobigerinus, from the south- east: vittatus, Owens Valley, if Casey is correct in his COLEOPTERA OF SOUTHERN CALIFORNIA. 193 disposition of Le Conte's virgatus: modestus, common at Pomona, Ojai Valley, etc., in flowers of Lupinus in spring; specimens apparently identical have been col- lected in the San Bernardino Mountains: pleuralis, one example taken at Pomona in January. Dorytomus. — D. incequalis, Los Angeles (Casey); San Diego, March; probably affects cottonwood as do the closely related mucidus and brevipilosns of the East: hystricula is very abundant: luridus is tolerably com- mon on willows when in blossom; Pomona, Pasadena, Riverside, etc.: hirtus was described from San Diego; this species is either a rarity or else an unusual form of the common thing which Casey has called hystricula: rufus, one example beaten from willows at Yuma: cuneatulus and marginatus are described by Casey from more northern parts of the State. Pachyphanes. — P. earns is described from "Cal. ;" it is probably not from our region: corpulentus is repre- sented by a single specimen, so named for me by Dietz, taken near San Francisco in August. Desmoris. — D. constrictus is abundant everywhere on sunflowers: fulvus and sordidus are reported from the State, and it is quite probable that both are found in the desert regions of the east or southeast. Dietz also describes incertus from the State. Smicronyx. — S. pusiUus, San Bernardino (collections of Horn and Dietz): cinereus, common and widely dif- fused: instabilis, rather rare at Pomona and Pasadena: defricans, not common, same localities as preceding: nubilus, Pasadena, Redondo, Palm Springs; not rare: calif ornicus, Pomona, Pasadena, Palm Springs; April to August: obtectus, Pomona, Long Beach, San Diego; 13 September 25, 1901. 194 CALIFORNIA ACADEMY OF SCIENCES. especially abundant at the latter place in March. Two or three undescribed species are in my collection. All the species are obtained, and usually in numbers, by sweeping flowers in spring and early summer. Of the following, also from the State, seriatus was originally from Mariposa, while perplexus, tardus, resplendens, pusio, scalator, and ornatipennis are not definitely located. Synertha. — S. imbricata, Mojave; San Bernardino Mountains, on pines. Promecotarsus. — P. maritimus, San Diego. Phyllotrox. — P. nubifer, Santa Barbara, February; Lake Tahoe, July. Endalus. — One example of limatulus from Los Ange- les County (Van Dyke): ovalis, Pomona; found about the roots of grasses in swampy places in winter: ceratus, Yuba County. Stenopelmus. — S. rufinasus, Santa Monica and Ven- tura, February and March; not common, San Diego (Crotch and Le Conte). Bagous — B. californicus, San Diego (Crotch). Phycoccetes. — P. testaceus is common at times under seaweed, from Santa Barbara to San Diego. Schizonotus. — 8. ccecus, San Francisco. The species was discovered by Mr. Fuchs, by sifting mouldy earth among the redwoods north of the Bay. Otidocephalus. — 0. vittatus, Owens Valley (Horn). Magdalis. — M. cuneiformis and M. lecontei may be beaten from coniferous trees along the higher portions of the southern Sierras. The former is comparatively COLEOPTERA OF SOUTHERN CALIFORNIA. 195 scarce, the latter not rare in the San Bernardino Moun- tains in July. An undescribed species depredates upon alders in the locality just mentioned. M. gracilis is apparently not rare in central and northern parts of the State: subtinctais described from Gilroy (Crotch): gentilis occurs at Lake Tahoe. Magdalinops. — M. vittipennis, "Cal." Macrorhoptus. — M. hispidus, San Diego, June; Po- mona, May: estriatus is recorded from Santa Barbara and Warner's Ranch (Crotch). Tachypterus. — T. quadrigibbus, "Gal." Cionistes. — One example of insolens was beaten from a sycamore at Pomona in October. I have seen numer- ous specimens collected near Bakersfield in April. Anthonomus. — Several specimens of peninsularis were taken at Palm Springs in April by Coquillett: confusus, Los Angeles County; rare: sycophanta is common on willows in the vicinity of Los Angeles: apertus, Los Angeles, Riverside, Pasadena; not common; taken by sweeping weeds along roads in April and May: albopi- losus is from the southeastern portions of the State: ceneolus is usually rare, but was taken in some abun- dance during October and November of several successive years, on Solanum nigrum in a canon near Pomona: ater, one example, on sunflowers at Pomona, April: ochreopilosus, Riverside and San Diego; quite common near the latter place in May: pauperculus , common at Riverside, Pomona, San Diego, and many other places in our district; taken by sweeping in waste places: ornatulus is found in similar places but is less common than the preceding: figuratus is unknown to me; it is said to have been taken at Santa Monica: inermis, 196 CALIFORNIA ACADEMY OF SCIENCES. southern Sierras from 3,000 to 5,000 feet altitude; not rare: stolatus, San Diego; several examples from Mr. George H. Field. The species following are also reputed to be Californian: brunnipennis, Geysers; moru- lus, near San Francisco; effetus, squamosus, hirtus, sub- vittatus, canus, and ajjinis are recorded from "Gal."1 simply; tahoensis is described from a small series taken at Tallac (Lake Tahoe) by Dr. Fenyes. Several of these doubtless were taken in the desert regions of the east and southeast, but I suspect that the identifications are not exact in all cases, and it would be well to await further evidence before placing the names in our list. Epimechus. — E. mimicus is not common; taken by sweeping in the foot-hills near Pomona in May and June: soriculus is found in the same localities as the preceding but is still less common; January, April, June, also Long Beach in April: nevadicus occurs a little more frequently than either of the preceding; Pomona, April to July: cemulus, one example from San Diego: adspersus has been taken by Dr. Fenyes at Monterey. Elleschus. — E. ephippiatus is rather plentiful on wil- lows in spring; Riverside, Ojai Valley, etc. Orchestes. — 0. parvicollis is common at Los Angeles, Pomona and San Diego from June to August: puberulus is not rare in the southern Sierras and the foot-hills near Pomona, Pasadena, etc: salicis is found near San Francisco: ephippiatus and rufipes are said to occur within the State; it is probable that they are northern or central. Tychius. — T. lineellus is abundant in flowers of Lupinus at Pomona and in the Ojai Valley; March to COLEOPTERA OF SOUTHERN CALIFORNIA. 197 May. Of T. prolixus one specimen has been found, also on Lupinus, at Pomona in May: setosus is obtainable in numbers on mesquite in the Colorado Desert; and with it is what appears to be an allied, undescribed species: semisquamosus is reported from Tejon.

Rhyncholus. — R. dorsalis, San Diego: angularis, Col- orado Desert, under willow bark: oregonensis, San Bernardino Mountains: R. spretus, San Bernardino Mountains, on freshly cut alder. Casey has described pattens from the vicinity of San Francisco, and dil- atatus from "Cal." Wollaston has described from Cal- ifornia, cylindricollis , calif ornicus , and protensus, all of which are unknown to American entomologists; but there is doubtless some synonymy involved in Casey's recent descriptions. SCOLYTID.E. Monarthrum. — M. scutellare and M. dentigerum have both been taken in March from burrows extending into the solid wood of live-oak; the latter species has been taken on the wing from April to June.

Hypothenemus. — H. striatus is recorded from both Lower and upper California, and is therefore undoubt- edly from our district. An undescribed species is fre- quently taken in spring, at Pomona, by sweeping and beating in waste places. Xyloterus. — X. lineatus, Sylvania, April (Ricksecker). Cryphalus. — C. terminates is described from California, but is not recognized by any of our authors.

An undescribed species occurs in Los Angeles County (Coquillett). Scolytus. — Specimens referred to ventralis have been taken on Douglas Spruce, in the San Bernardino Moun- tains. Specimens have also been received from Mendo- cino County, where they affected the same tree according to Dr. Van Dyke. S. prceceps is reported from Calaveras (Crotch): subscaber is from the north: californicus is without other locality than that indicated by the name. COLEOPTERA OF SOUTHERN CALIFORNIA. 203 Hylesinus. — H. aspericollis is not rare in the southern Sierras: specimens referred to imperialis have been seen from the vicinity of San Francisco: sericeus is found in the middle and northern Sierras.

Hylurgops. — H. subcostulatus occurs throughout the Sierras: granulatus and rugipennis are thus far known only from the more northern parts of the State. ANTHRIBID^. Toxotropis. — T. approximatus was beaten from dead twigs of live-oak, near Pomona, in June. Gonops. — G. fissunguis, " Big Trees.7' Brachy tarsus. — I have seen four species from the State, none of which are identified with certainty; one of these is certainly exceedingly close to, if not identical with, the eastern alternatus; specimens have been taken at Redondo by sweeping. Two other species are from Southern California. 204 CALIFORNIA ACADEMY OF SCIENCES. The following table shows by families the number of genera and species mentioned in the preceding pages, both for Southern California and for the entire State. Between these is introduced for comparative purposes similar data from Dr. Hamilton's List of the Coleoptera of Southwestern Pennsylvania. The number of spe- cies named by Dr. Hamilton being substantially equal to the number here recorded from Southern California, a comparison of figures will give a very good idea of the relative abundance of the various families on the Atlantic and Pacific slopes. A few numbers in the Pennsylvania list are marked with an asterisk (*) to indicate that in these cases the record is incomplete: — COLEOPTERA OF SOUTHERN CALIFORNIA, 205 FAMILY. SOUTHERN CALIFORNIA.
