C. inflatlis n. sp. — Eobust, strongly convex and shining, the elytra 

 inflated. Head rather less than one-half as wide as the prothorax, not very 

 coarsely but densely punctate, the punctures usually sparser toward the 

 middle ; epistoma extremely densely punctured. Prothoi-ax about twice as 

 wide as long, the apex nearly three-fourths as wide as the base, the latter 

 broadly truncate, the angles narrowly and abruptly produced posteriorly, very 

 acute ; sides feebly arcuate, more strongly so near the apex ; disk moderately 

 densely, very coarsely and deeply punctate laterally, more sparsely and much 

 more finely so near the middle ; side margins very finely, acutely beaded. 

 Elytra about three times as long as the prothorax, and, at posterior third, 

 distinctly wider, rather coarsely but not densely punctate, the punctures 

 becoming much smaller toward apex. Abdomen sparsely but rather strongly 

 punctate. Length 6.5-7.4 mm. ; width 3.4-3.9 mm. 



Nevada (Reno). 



Differs considerably from either obesus or suhglaher in its much 

 more robust form, inflated and relatively longer elytra, and the 

 much more conspicuous setEe toward the apex of the latter. The 

 scutellum in the three specimens before me is much smaller and more 

 acute than in obesus, and very slightly smaller than in suhglaher. 



C. otoesilS Lee. — Coniontis oh. : Ann. Lye. N. Y., V, p. 131 nota. — Robust, 

 subparallel, convex, rather strongly shining. Head well developed, finely, 

 rather densely punctate, more sparsely so near the middle. Prothorax fully 

 four-fifths wider than long, the apex three-fourths as wide as the base, the 

 latter transversely truncate, the angles very narrowly, abruptly and moder- 

 ately produced posteriorly, very acute ; sides feebly arcuate ; disk rather 

 densely and decidedly coarsely punctate, less coarsely and more sparsely so 

 toward the middle ; side-margin very fine and acute, extremely narrowly 

 refiexed. Elytra nearly two and one-half times as long as the prothorax, 

 abruptly narrowed in apical third which is angulate and acutely rounded at 

 apex ; disk rather coarsely, deeply and moderately densely punctate, the 

 punctures a little more sparse and feeble toward apex. Abdomen sparsely, 

 rather finely but very distinctly punctured, the punctures rounded. Length 

 6.0 mm. ; width 3.1 mm. 



Colorado (Long's Peak). Cab. LeConte. 



The description refers to the original type which is unique. The 

 elytral seta; toward apex, when viewed along a line tangent to the 

 surface, are seen to be rather fine, erect, not dense and about one- 

 half as long as the third joint of the posterior tarsus. The lateral 

 pronotal punctures are coarse, very slightly longer than wide, and 

 not at all coalescent. 



C. SlllbglalJer n. sp. — Form as in obesus. Head moderate, xerv finely, 

 densely punctate. Prothorax nearly as in obesus, the disk unevenly, very
