slightly rugose at sides and in front; clypeus feebly einarginate in front, 

 the angles each side of notch obtuse. Thorax with distinct basal marginal 

 line, hind angles nearly rectangular ; disk finely and sparsely punctured at 

 middle, more coarsely and densely on sides. Elytra as wide at base as tho- 

 rax, a little broader behind the middle ; striae fine, deep, closely but not 

 coarsely punctured: intervals very flat, each with two indistinct rows of

Henry and Vigo counties , scarce. January 13-March 10. Hi- 

 bernates beneath cow dung and partly buried logs. Horn says 

 the clypeus is without tubercles. Say, in his original description,

 guishing characters. Traces of the tubercles are present in all 

 specimens at hand and in some of them they are quite distinct.
