 not coarsely punctate; pubescence coarse and conspicuous. Length 1.5- 

 2 mm. 



Starke, Putnam and Posey counties; a single specimen from 

 each. March 20-December 6. One was taken from beneath chunk 

 in a fence row on the latter date.

 were taken from a freshly cut maple stump where they were feed-

 the hind coxal cavity, sometimes touching, at the apex of the curve, 

 the first suture and ending nearly at the outer front angle of the 

 segment. (Pig. 194. No. 4.)

 &. Elytra pale at apex, either merely bordered with yellow T or with an
