slightly dilated and thickened laterally; apex hroadly arcuate; punctures 

 strong and very close-set, the interspaces polished. Elytra short, scarcely two- 

 thirds longer than wide, broadly rounded at apex, the sides parallel and very 

 feebly arcuate; humeri somewhat widely and transversely exposed at base; 

 scutellar impression very feeble, the omoplates obsolete; disk densely and 

 deeply but only moderately coarsely iiunctate. Ahdomen polished, finely, 

 closely punctate, the legs very slender. Length 2.0 mm. ; width 0.7 mm. 



California 



Tliis small and inconspicuous species is sufficiently differen- 

 tiated from the preceding by its short elytra, small and more 

 rounded prothorax, and other characters as heretofore stated. I 

 have placed with the California type, taken b}' Mr. Wickham, two 

 pale specimens, one with nubilate elytra taken in the southern 

 part of the State b}- Mr. Dunn, also a specimen taken at Poca- 

 tello, Idaho, by Mr. Wickham, which has the pubescence still 

 longer and more shaggy, and finally a larger blackish specimen 

 from New Mexico. 



The species in this particular part of the series are so closely 

 allied and apparently so indefinite, that I can only select at pres- 

 ent a few of the more obviously distinct ones for description as 

 landmarks ; much more extensive material will be required to 

 enable the future reviewer to fully differentiate them. 



55. A. iiilliidlis n. sp. — Moderately narrow and convex, shining, rufo- 

 testaceous, the entire under surface of the hind body black; elytra black, with 

 two large humeral areas meeting near the scutellum, and two oblique oval 

 apical spots meeting on the suture at apex, of palerufo-testaceous; pubescence 

 rather long, coarse, cinereous and conspicuous. Head subquadrate, convex, 

 somewhat wider than long, minutely and not densely punctured, with a nar- 

 row impunctate line, broadly arcuate at base ; eyes moderate in size but promi- 

 nent, not as long as the tempora, the latter nearly straight and perceptibly 

 convergent from the eyes to the basal angles, which are obtuse but only nar- 

 rowly rounded; antennaj slighly shorter than the head and prothorax, very 

 feebly incrassate, joints eight to ten, aliruptly much shorter than the preceding, 

 equal in length, the tenth not as long as wide. Prothorax small, distinctly 

 narrower than the head, not as long as wide, narrowly rounded at apical 

 fourth, tlie sides thence oblicjue and straight to the basal margin ; disk rather 

 finely but deeply, not very closely punctate. Elytra two-thirds longer than 

 wide, twice as wide as the prothorax, the sides parallel and feebly arcuate; 

 apex not broadly rounded ; humeri widely and transversely exposed at base; 

 post-scutellar impression somewhat narrow and distinct; omoplates obsolete; 

 disk strongly but not coarsely, rather densely punctured. Atxlomoi. polished, 

 finely punctate, tlie legs very slender. Length 2.1 mm.; widtli 0.75 nun.
