190 Coleopterological Notices, III. 



Abdomen densely clothed with longer cinereous pubescence and sparsely 

 speckled with rather coarse subdenuded punctures. Legs short and but 

 moderately robust. Length 7.5-9.5 mm. ; width 3.2-3.6 mm. 



New Mexico (Las Yegas and Coolidge) ; Wyoming (Cheyenne). 



A rather isolated species, somewhat resembling collaris or can- 

 escens at the first glance, but distinguished from both by its much 

 shorter less dense vestiture and very coarse punctuation, and from 

 collaris in addition, by its much less constricted prothorax and 

 narrower less depressed form. In proportion to the size of the 

 body the beak is larger than in any other of our species. 



C. "bicarinatus. — Short, robust and convex, black throughout, the 

 head and pronotum dull and more pubescent, the elytra polished and in 

 great part glabrous, the vestiture cinereous, short and subsquamiform, form- 

 ing two narrower and indefinite discal vittse and a denser marginal line on 

 the pronotum, the elytra pubescent near the base, also feebly on the third 

 interval near the apex, the fifth behind the middle, the ninth throughout, 

 and on the eleventh or marginal interval partially and sparsely. Head very 

 finely, densely punctulate, the beak sparsely so and with large, rather densely 

 rugulose punctures ; beak robust, dilated at apex, scarcely shorter than the 

 prothorax, broadly carinate toward base and separated from the head by a 

 transverse impression between the eyes. Prothorax slightly wider than long, 

 the sides very feebly convergent and nearly straight to apical third or fourth, 

 then more convergent and feebly sinuate to the apex, which is slightly arcuate 

 and scarcely three-fifths as wide as the base, the latter broadly cusped ; disk 

 broadly, feebly impressed before the scutellum, feebly subcarinate thence to 

 the apex, finely, strongly, very densely punctulate throughout and with large 

 deep scattered punctures. Elytra four-fifths longer than wide, three times as 

 long as the prothorax, and, behind the middle, fully two-fifths wider than the 

 latter, broadly parabolic and distinctly notched at apex, the humeri exposed 

 and slightly tumid ; disk with unimpressed rows of rather coarse distant 

 punctures, the series obviously impressed near the suture ; each elytron with 

 a short, strongly tumid carina in the middle toward base. Under surface 

 rather densely clothed with long coarse hair, densely speckled on the abdomen 

 with large subdenuded punctures. Legs rather short and slender, rugulose, 

 very sparsely pubescent. Length 10.0 mm. ; width 4.2 mm. 



Texas (near Austin). 



A distinct species, not closely related to any other known to me, 

 and notable chiefly for the dense punctuation of the anterior por- 

 tions of the body, and the short convex polished and almost glabrous 

 elytra which are bicarinate toward base. 



C lecontei. — Elongate, suboval, strongly convex, deep black, the in- 

 teguments extremely sparsely pubescent and polished, except in the narrow
