margin with a short perpendicular groove. Elytra distinctly 

 punctate-stnate ; their epipleurae very broad, concavei and continued 

 to the apices; posterior femora strongly thickened; tibije not 

 channelled, the posterior ones with a short spine ; the first joint of 

 the posterior tarsi as long as the two following joints together ; 

 claws appendiculate. Prosternum broad, one half longer than broad. 

 Me^osternum transversely quadrate. Anterior coxal cavities open. 



Ihe rounded convex shape, the short perpendicular basal grooves 

 ot the thorax, in connection with the punctate-striate elytra, the 

 broad prosternum, and open coxal cavities separate this genus.

Head impunctate, the clypeus thickened ; labrum margined with

 thickened angle before the middle; surface finely but distinctly and 

 not very closely punctured, black. Scutellum fulvous. Elytra
