than any of the other species of the genus. The male is one of the finest entomological prizes which will reward the collector in Western America. Differs from our other two species by the color, and by the base of the thorax being less sinuate, whereby the posterior angles become more rectangular.

Lachnosterna errans, fusco-ferruginea, oblongo-ovata, convexa, capite fortiter hand confluenter punctato, clypeo fortiter marginato, fere integro, thorace antice angustato sat dense punctato, lateribus angulatis, longe ciliatis, elytris haud costatis fortius punctatis, pygidio parce subtiliter punctato, pectore longe villoso, unguiculis dente mediocri armatis, Long. 70.

One male, Contra Costa, California; Mr. J. Child. Resembles closely in form and sculpture L. cephalica Lec., Journ. Acad. Nat. Sci. Phila., 2d series, 3, 245, but the sides of the thorax are fringed with long hairs, angulated at the middle and then narrowed with a concave outline to the apex: the clypeus is scarcely emarginate. The antennæ are 10-jointed, the club is as long as the basal portion; the penultimate ventral segment has a transverse crest concave posteriorly, and finally the fixed spur of the posterior tibiæ is very short, the moveable one about twice as long, curved, flattened and subobtuse.

✔Dichelonycha pallens, breviuscula, testacea, parce pubescens, clypeo reflexo, angulis rotundatis, thorace latitudine duplo breviore, apice fere truncato, antice angustato, lateribus valde rotundatis, medio subangulatis, angulis posticis valde obtusis, confluenter dense punctato, elytris punctatis subcostatis, antennarum clava nigro-picea. Long. 30.

One specimen, Punto de los Reyes. Resembles D. testacea Kirby, but is much smaller, comparatively wider, the clypeus less rounded at apex, the thorax more rounded on the sides, with the posterior angles more obtuse.

Adelocera rorulenta, rufo-picea, punctata, nigro-squamosa, squamisque aureis parce conspersa, thorace latitudine paulo longiore, late profunde canaliculato, ante medium magis angustato, lateribus rotundatis, angulis posticis planis haud divergentibus, elytris depressis vix obsolete striatis, tarsorum anticorum sulcis parum distinctis. Long. 59.

Steilacoom, Dr. Suckley, one specimen. Resembles A. aurorata, and in the absence of a specimen for comparison, was incorrectly referred by me to that species (P. R. R. Expl.. xi. 18,); it is, however, less elongated, with the posterior angles of the thorax not divergent, and the tarsal grooves on the under surface of the prothorax are much less apparent.

Dascyllus Davidsonii, fusco-piceus, dense pubescens, confertissime punctulatus; thorace latitudine plus duplo breviore, antrorsum angustato, lateribus rotundatis, basi late bisinuato, elytris striis approximatis, punctatis antice obliteratis, antennis valde serratis, articulo 3io sequenti æquali. Long. 48-52.

Punto de los Reyes, Mr. Davidson, to whom I take great pleasure in dedicating this fine species. It differs from those previously described by the strongly serrate antennæ; these organs are half the length of the body in the female, and a little longer in the male; the second joint is small, the third, fourth and fifth are triangular, and nearly as wide as long; the following ones gradually diminish in breadth; the eleventh is oval elongate and constricted at the end. The last segment of the abdomen is marked towards the base with a semicircular impression, with the concavity behind, as though it were formed by the union of two segments.

Charopus moerens, nigro-virescens, alutaceus opacus, tenuissime pubescens, thorace latitudine sublongiore, ovato, postice subangustato, margine pone medium anguste testaceo, postice transversim vage impresso, elytris (feminæ) elongatis postice sensim latioribus, apice rotundatis, abdomine paulo brevioribus. Long. 13.

One specimen, Punto de los Reyes, Mr. Davidson. The first example of the occurrence of the genus upon this continent. The head is slightly wider than the thorax: the latter is feebly sinuate on the sides behind, the elytra are more distinctly green, they are twice as long as the head and thorax united, and nearly cover the abdomen, which is subacute at tip. The antennæ are half as long as the body, with the second joint a little shorter than the third.

Anobium gibbicolle, fuscum, pube subtilissima sericans, valde elongatum, thorace latitudine fere sesqui longiore, antice angustatum, lateribus sinuatis, apice basique rotundato, medio utrinque ad latera oblique profunde impresso, disco postice me lio valde elevato, ad angulos posticos profunde impresso, angulis rotundatis marginatis, elytris, thorace latioribus striis punctatis interstitiis paulo convexis. Long. 22.

One specimen, Punto de los Reyes: Mr. Davidson. Belongs to the division having 11-jointed antennæ: the joints 4-8 are very small; the 3d is a little longer; the 2d is longer and thicker, though not as large as the basal joint: the 9th, 10th and 11th are equal, narrow, and each one is as long as the joint 3-8 together. The body is still narrower than in A. foveatum Kirby, and the posterior angles of the thorax are rounded: the sides near the anterior angles are emarginate, so that the latter become distinct, though deflexed: the eyes are small and convex, and the head is transversely impressed just behind them.

Anobium punctulatum, rufo-testaceum, cylindrico-ovale, pubescens, capite confertim punctato, thorace brevi æqualiter convexo, lateribus rotundatis late marginatis, confertim punctulato, elytris thorace haud latioribus sat dense punctulatis; antennis articulis 3 ultimis singulatim præcedentibus duobus æqualibus. Long. 13-18.

Two specimens, Punto de los Reyes. Very similar to A. convexifrons Mels., but differs by the punctures of the elytra being less close. The antennæ as in it are 11-jointed: the joints 2, 4, 6 and 8 are a little shorter than the others, the 9th, 10th and 11th are each equal to the 7th and 8th together.

Helops opacus, apterus, ater opacus, capite thoraceque densissime punctatis, hoc latitudine sesqui breviore, modice convexo, lateribus tenue margin. atis rotundatis, postice subangustato, basi truncato, angulis posticis subrectis, elytris connatis oblongo-ovatis, convexis, thorace paulo latioribus, postice valde declivibus, punctis oblongis striatis, interstitiis haud convexis, rugosis et confertim punctatis. Long. 53.

One specimen, Sacramento, California, given me by Mr. Rathvon. The three joints of the anterior and middle tarsi are densely hairy beneath, but scarcely

dilated.

Long. 21.

Oregon. Mr. Davidson. This species so resembles in its characters Dircea Holmbergii Mann., Bull. Mosc., 1852, 347, that I cannot help suspecting that they are identical. A renewed examination of Mannerheim's type would be necessary, however, before such a suggestion could be admitted.

Notoxus sparsus, elongatus, testaceus nitidus, pallide pubescens, capite thoraceque rufo-tinctis, hoc globoso, cornu elongato, apice fortiter marginato et concavo, crista subito elevata, supra marginata et paulo concava, elytris thorace paulo latioribus, parcius subtiliter punctatis, gutta utrinque subscu

Long. 13.

Punto de los Reyes, one specimen. Of the same form and size as S. virescens Lec., but with the striæ of punctures of the elytra more plainly marked, and without the interstitial rows of equally large punctures, which are so obvious in that species.

Cossonus scrobiculatus, niger nitidus, elongatus, rostro punctato, ad apicem subito parum dilatato, capite fere lævi, thorace latitudine longiore, antrorsum angustato, lateribus late rotundatis, rude punctato, dorso postice paulo deplanato, medio subcarinato, elytris convexis, cylindricis, thorace paulo latioribus, striis cribrosis, interstitiis striis haud latioribus. Long. 20. Punto de los Reyes, Mr. Davidson. The rostrum has an oblong impression at the middle, and the front is marked with a small fovea.

Punto de los Reyes. Similar to C. æreum Newman, but differs by the head being finely punctured, the thorax more densely punctured, and by the abdomen being testaceous.

Brothylus conspersus, nigro-piceus, pube brevi griseo-sordida densa variegatus, thorace latitudine haud breviore, lateribus subrotundatis vix obsolete tuberculatis, postice sinuatis, rude parce varioloso, cailo utrinque discoideo alteroque postico parvis, elytris thorace latioribus, granulis elevatis, punctisque minus densis, postice sensim subtilioribus; fasciis duabus vagis obliquis minus pubescentibus. Long. 73-77.

Oregon, Mr. Davidson and Dr. Kennerly. Similar to B. gemmulatus Lec., Proc. Acad., 1859, 80, but differs by the lateral tubercles of the thorax being obsolete. The antennæ of the male are as long as the body, those of the female one-fourth shorter.

Chrysomela sigmoidea, nigro-ænea, oblongo-rotundata, thorace sat dense, ad latera fortius punctato, elytris thorace parum latioribus albo-testaceis, sat dense punctatis, sutura, vitta confluente antice breviter discreta, vittis duabus curvatis, interiore antice, exteriore postice abbreviatis, guttisque externis paucis nigro-æneis. Long. ·32.

Oregon; a specimen kindly given me by Mr. Henry Ulke. More nearly allied by its markings to C. dislocata Rogers than to any other of our species, but differing by the much wider thorax, and more dense punctures

both of thorax and elytra, as well as by the markings of the latter. The inner curved stripe extends from one-sixth from the base to one-third from the apex; the outer one is contiguous to it, connected with a humeral spot, and abbreviated behind at the middle.

Haltica æruginosa, oblongo-ovalis, modice convexa, obscure cuprea, subnitida, thorace convexo, subtilissime punctulato, linea transversa postica obsoleta, antrorsum subangustato, lateribus parum rotundatis, elytris thorace latioribus, dense punctulatis. Long. 16.

Table Mountain, below San Francisco, Mr. Davidson: two specimens. These three species belong to the division Graptodera Chevr.

Dibolia ovata, ovata, convexa, nigro-ænea, nitida, subtiliter punctulata, elytris seriebus punctorum subtilibus postice haud distinctis, antennis nigris basi testaceis, tibiis tarsisque anterioribus testaceis, femoribus obscuris. Long.

.12.

One specimen, Punto de los Reyes. The posterior thighs are black, and the tibiæ and tarsi dark brown. Broader and more ovate than D. area Mels., with the rows of punctures of the elytra very fine, not impressed, and obliterated behind.

Luperus smaragdinus, elongatus, cyaneo-viridis, antennis nigris basi fuscis, thorace convexo, quadrato, lateribus paulo rotundatis, anticis prominulis rotundatis, parce subtiliter punctulato, elytris sat dense punctulatis. Long. 23.

Punto de los Reyes, three specimens, Mr. Davidson. Resembles L. varipes Lec. but differs by the entirely black legs, and by the thorax being much less densely punctulate. The second and third joints of the antennæ together are equal to the fourth; the third is one half longer than the second.

Coccinella melanopleura, ovalis, modice convexa, capite thoraceque haud dense punctulatis, illo maculis duabus albis, hoc limbo antico, lateribus late (macula nigra inclusa) lineola apicali, maculisque duabus basalibus albis, scutello nigro, elytris ferrugineis, confertim subtiliter punctatis; subtus nigra, tibiis tarsisque fusco-testaceis. Long. 21.

Table Mountain, Mr. Davidson, one specimen. Closely resembles the varieties of C. pict a, with immaculate elytra, but differs by the body being entirely black beneath, and by the elytra being more finely punctured. It is probable that varieties will occur with white thorax having black spots, and also with elytral markings.

Coccinella barda, hemisphærica, capite punctulato, albo, postice nigro, thorace parce punctulato, nigro, macula magna utrinque, limboque antico albis, elytris subtiliter dense punctatis, ferrugineis, fascia transversa communi pone basin nigris, scutello, suturaque ad basin nigris; subtus nigra, epimeris albis. Long. 21.

Punto de los Reyes, one specimen, Mr. Davidson. There is no trace of any posterior spots on the elytra: the band stops on the humerus, and is slightly widened there.
