 erect ; antennae and legs paler. Head and thorax finely and sparsely punc- 

 tate. Elytra with somewhat coarse punctures in more or less regular rows;

Oval, moderately elongate, convex. Black, shining, clothed with fine, 

 recumbent grayish pubescence; tibue more or less reddish; antennas and 

 tarsi paler. Joints of autennal club ernarginate on their apical edge in 

 female, so deeply ernarginate as to become branched in male. Thorax short, 

 with sides strongly convergent and nearly straight; surface finely punctate. 

 Elytra with well marked trace of third lateral stria; surface with punc- 

 tures distinctly coarser and usually closer than those of thorax. Length

 broadly truncate and notched behind and the fifth ventral segment 

 relatively longer. The antennce vary in the number of joints 

 present, there being from eight to ten, according to species. But 

 one species has been taken in Indiana, though another probably 

 occurs.
