70 J. L. LECONTE, M. D. 



BL.APSTINUS Latr. 



B. Inf ifroiiN. — Oval, rather elongate, moderately convex, di-ll black, 

 densely fmnctured, finely pubescent; front wider before the eyes and distinct- 

 ly angulated at the sides; prothorax a little wider than the elytra, twice as 

 wide as long, narrower in front, much rounded on the sides, base sinuate to- 

 wards the sides and broadly truncate at the middle; hind angles obtuse, well 

 defined ; disc broadly convex, sides widely depressed. Elytra a little narrow- 

 er than prothorax, elongate, sides parallel, tip rounded, striae fine, finely punc- 

 tured, not deeply impressed, interspaces nearly flat. L. 9.7 mm.; .38 inch. 



One specimen, Vancouver Island; Mr. Crotch. Near B sordidtis, 

 but larger, narrower and distinct by the clypeus being angulated at 

 the sides, the prothorax narrowed towards the base, and more strongly 

 rounded on the sides, and by the interspaces of the elytra not alterna- 

 tely more convex. 



ASC'LERA Schmidt. 

 A. discolor. — Black, finely pubescent; mouth, prothorax and elytra dirty 

 yellow; prothorax very finely punctulate, narrowed and constricted behind, 

 disc with two very large excavations and a smaller one near the base; elytra 

 densely ami finely punctureb, with Ihe usual 3 elevated lines, the inner one 

 less distinct; dusky towards the tip; legs dusky, tip of thighs and base of 

 tibise yellow. Length .2" inch; 7 mm. 



(■aliCornia; Mr. Crotch, eight specimens. This species precisely 

 resembles ^4. excavata and ni[/ra JiCC, diiFering only in color. 



RHI^'A Kirby. 

 R. fronfnlis. — Black, shining; bead sparsely coarsely punctured, beak 



straight, as long as the prothorax, coarsely and comewhat densely punctured, 

 obsoletely s>ulcate and 3f)arsely setose each side; frontal fovea distinct; eyes 

 nearly contiguous beneath, but widely separated above; prothorax a little 

 longer than wide, narrowed in front, and broadly rounded at the siiles, apex 

 tubularly constricted, disc coarsely but not densely punctured, base nearly 

 straight, margined ; elytra cylindrical with rounded humeri, sides parallel, 

 apex rounded, strife finely punctured, interspaces flat, with a few distant 

 small punctures; prothorax with the flanks and under surface densely and 

 coarsely punctured, trunk and abdomen sparsely punctured, front tibire with 

 5 — t") small teeth on the inner edge. Length .32 — .45 inch ; 8 — II mm. 



Mojave Desert, under bark of Vucca j Mr. Crotch. This species 

 differs from the others by the eyes not extending on the upper sur- 

 face of the head, so that the front is broad and convex. The appear- 

 ance is that of a gigantic Cossonide. The pygidium is almost covered 

 by the elytra, but projects a little as in R. barbirostris. 



Further study may require this to be separated as a distinct genus. 



CRYPIIAL,US Er. (emend.) 



C. cariimlatus.— Cylindrical, less elongate than usual, black or brown, 

 thinly clothe*! with long erect hairs; prothorax one-third longer than wide, 

 sides parallel, apex rounded, hiud angles obtuse and rounded, disc rough in
