 tral. The males have the thorax and elytra darker reddish-brown, 

 and the latter much more cciarscly punctate. 



C. pimen'anuni Lee. S. 5-10. 5 mm. in length, is recorded by Casey 

 from Indiana. I have not seen a speiimeu from the State. Its 

 usual range is Texas to California.

This genus was created by Casey to include those species hitherto 

 a.scribed to ('riipfaliutin which have the first and si cond ventrals of 

 male without a trace of pit or fovea and the last ventral distinctly 

 notched at apex. I include with them srrpnitinum LeConte, as the 

 characters separating it are not sufficient to erect a new genus.
