284 PROCEEDINGS OP THE ACADEMY OP 



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 

 tnore distinctly green, they are twice as long as the head and thorax united, 

 and nearly cover the abdomen, which is subacute at tip. The antennae 

 are half as long as the body, with the second joint a little shorter than the 

 third. 



Anobium gi bbic olle, fuscum, pube subtilissima sericans, valde elonga- 

 tum, thorace latitudine fere sesqui longiore, antice angustatum, lateribus sin- 

 uatis, apice basique rotundato, medio utrinque ad latera oblique profunde 

 impresso, disco postice melio valde elevato, ad angulos posticos profnnde im- 

 presso, angulis rotundatis marginatis, elytris, thorace latioribus striis puncta- 

 tis interstitiis paulo convexis. Long. '22. 



One specimen, Punto de los Reyes : Mr. Davidson. Belongs to the division 

 having 11-jointed antennse : 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, pnbescens, 

 capite confertim punetato, thorace brevi aequaliter convexo, lateribus rotunda- 

 tis late marginatis, confertim punctulato, elytris thorace haud latioribus sat 

 dense punctulatis ; antennis articulis 3 ultimis singulatim prsecedentibus 

 duobus sequalibus. Long. -l^lS. 



Two specimens, Punto de los Reyes. Very similar to A. convexifrons 

 Mels. , but differs by the punctures of the elytra being less close. The antennae 

 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 op a c u s , apterus, ater opacus, capite thoraceque densissime punc- 

 tatis, 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 striati3, interstitiis haud convexis, rugosis et con- 

 fertim 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. 



Hypulus fulminans, elongatus piceus, parce pubescens, sat dense pro- 

 funde punctatus, thorace latitudine haud breviore, lateribus rotundatis, angulis 

 posticis subobtusis, basi utrinque late et profunde foveato, elytris fasciis tri- 

 bus valde angulatis, lma obliqua, intus cum secunda connexa, maculaque 

 magna ante apicali pallidis, antennis fuscis basi testaceis, femoribus tibiisque 

 medio fuscis. Long. '21. 



Oregon. Mr. Davidson. This species so resembles in its characters Dircasa 

 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 spars us , elongatus, testaceus nitidus, pallide pubescens, capite 

 thoraceque rufo-tinctis, hoc globoso, cornu elongato, apice fortiter marginato 

 et Cdncavo, crista subito elevata, supra marginata et paulo concava, elytris 

 thorace paulo latioribus, parcius subtiliter punctatis, gutta utrinque subscu-
