This insect is so nearly allied to C.fralernus, (differing chiefly in 

 the form of the lower border of the face,) that at first I had consi- 

 derable hesitation in considering it as more than a local variety of 

 that species ; as, however, it comes from an entirely different loca- 

 lity, I have thought it better for the present to keep it distinct. 

 The epistome, instead of being trilobate as in C. fraternus, is 

 truncate, produced in the middle into a distinct lobe, the sides 

 being each distinctly but slightly concave. The thorax is slightly 

 broader and obsoletely excavated on either side the disk. In the 

 form and sculpturing of the elytra it does not present any differ- 

 ence from C.fralernus.
