Diagnosis. — Among the species with one setigerous puncture on 

 the submargin of the head and one on the costa, the males of this one 

 may bo recognized by the lack of ventral, subbasal angulation on the 

 hind tibia coupled with the presence of but four spines on the postcro- 

 vcntral margin of the posterior tibia.
