One male from New York, Mr. Guex. This species has nearly the form, sculpture 

 and sexual characters of the preceding, but there are no hairs on the upper surface 

 except between the eyes. From the next species it differs by its more cylindrical 

 form, more sparsely punctured thorax, and by the more strongly margined and less 

 emarginate clypeus.

clypeo emarginato, tenue marginato, thorace parum convexo, antrorsum angustato, lateribus obtuse sub-

One male found at Lake Superior. Body oblong, less convex than usual, reddish 

 brown, darker on the head and thorax. Head strongly and closely punctured, with

 as its length, obtusely angulated at the middle of the sides, narrowed in front, but 

 not behind, strongly but not densely punctured, with the sides partly ciliate, and 

 towards the base slightly serrate. Scutellum with two groups of punctures. Elytra
