1. C. collaris, n. sp. 



Black, thickly clothed with short dirt-colored pubescence ; beak not di- 

 lated at tip, sides suddenly deflexed, nearly fiat above, with a very tine 

 slightly elevated line, gradually becoming impressed in front, and not 

 reaching the tip, ending behind in a small frontal fovea. Protliorax Avider 

 than long, sides irregularly rounded, bent obliquely inwards near the base, 

 suddenly I'ounded and narrowed near the apex, which is bisinuate, and 

 strongly impressed at the sides ; disc sparsely cribrate, obsoletely carinate 

 before the middle, very deeply excavated behind, sides with a curved im- 

 pression which makes the outline sinuate when viewed from above. Ely- 

 tra each with a deep rounded sub-basal impression, and an oblique lateral one 

 at about one-fourth of the length ; strice composed of large somewhat dis- 

 tant punctures, which appear somewhat unequal in size, as they are more 

 or less covered with the pubescence ; the first and marginal interspaces 

 seem to be tesselated with darker. Beneath clothed with dirt-colored pu- 

 bescence and speckled with black. Length 11 mm. ; .45 inch. 



One specimen from Colorado. Dr. Horn. The front and middle tarsi 

 are spongy beneath, with the third joint broad and bilobed ; the hind tarsi 

 are not spongy, the third joint is shorter than the second, but scarcely 

 wider, and deeply emarginate rather than bilobed.

3. C.inornatus. u. sp. 



Black, head densely punctured with a few coarse punctures, beak coarsely 

 punctured, the latter distinctly carinate, and marked with two vittse of 

 pale-brown hair ; protliorax longer than wide, gradually narrowed from 

 the base forwards, feebly rounded on the sides, not constricted and but 

 feebly impressed on the sides towards the tip ; base bisinuate, middle lobe 

 broadly rounded ; disc denselj^ punctured, sparsely and very coarselj^ 

 punctured, broadly but not deeply foveate-atbase, distinctlj' carinate in front 

 of the impression, with four stripes of pale-brown hair, the discoidal ones 

 being sinuate, the outer ones lateral. Elytra without imiiression, humeri 

 rounded, sides parallel, strise composed in front of rather distant punctures, 

 but becoming definitely impressed toward the tip ; densely clothed with 

 rather coarse pale brown pubescence, which is a little thinner on the sec- 

 ond and eighth interspaces. Beneath similarly pubescent, speckled with 

 black. Length 13.5 mm. ; .53 inch.
