 rugulose elevation in front of a rather deep, smooth depression ; last seg- 

 ment vaguely and transversely impressed. Female \Aith pubic process long, 

 deeply forked, the branches truncate at tip. Length 16-20 mm. (PI. II, 



flg. asn.) 



Lake, Porter, Putnam and Perry counties; scarce. April 22- 

 July 16. Ranges from New York to Illinois and southward. The 

 more slender, obloni^- body, distinct suhmarginal eosta and coarsely 

 and irregularly punctured thorax should readily distinguish this 

 species.

 18 mm., is a rare species described from Maryland and Iowa.

 Elytral punctures finer and more dense than those of thorax, somewhat 

 rugulose on the sides; the costre usually ver.\- feeble, iletasternum densely 

 punctured, the hair not long or dense. Male with antenual club equal to or
