Hetaerius setosus n. sp. 



Form broadly quadrate oval. Color ferruginous. Punctate and setose. 



Head but slightly concave at vertex, which is evenly, moderately 

 punctate, each puncture bearing a long bristle-like seta ; front impunc- 

 tate, shining, minutely rugose ; labruin smooth shining. 



Prothorax twice as wide as long ; minutely rugose except in the 

 oblique depression which, is smooth and impunctate ; disc evenly, mod- 

 erately punctate and setose, the setae long, recurved and tapering to a 

 sharp point, minutely plumose along cephalic margin. Lateral areas more 

 closely punctured and setose, these setae becoming coarser, longer and 

 more evidently plumose at the outer edge ; sides evenly rounded from 

 transverse sulcus to apex ; inner carina of the oblique sulcus bends 

 sharply inward opposite the transverse sulcus, by this separation pro- 

 ducing a deep triangular depression opposite the bulla and narrowing 

 the oblique depression at this point. Bulla smooth shining on inner half, 

 outer portion punctate and bordered by coarser and longer plumose 

 setae. 



Elytra shining and minutely rugose; space between the first dorsal
