" Little convex, little shiny, black, head and prothorax sub-bronze- 

 black, briefly flavous pubescent, the pubescence, however, longer on 

 the head and on the declivity of the prothorax ; head smooth and 

 having only a few sparse punctures, clypeus and genus rugose, the 

 former hardly sinuate, frontal part arcuately carinate, vertex having 

 between the eyes in the 3 a short, erect lamina truncate at apex, 

 and in the 2 a somewhat long, straight carina ; prothorax entirely 

 but not closely asperate punctate, briefly and strongly carinate in the 

 middle, the said carina oftener excised in the centre ; sides hardly 

 sinuate behind, base marginate ; elytra broadly striate, intervals 

 plane, sparingly granulate ; pygidium moderately strongly punctate.

 the $ situated between the eyes and at about the middle, and in the
