 hind; punctate, punctures small and arranged in regular series, 

 intervals each with a row of irregularly spaced smaller punctures, 

 jDunctures confused laterally, sometimes diffusely punctate through-

Epijjleurm somewhat wide, scarcely dilated beneath the humeri, 

 thence gradually narrowing to apex, superior margin feebly and

Parapleurw rather coarsely punctate. 



Abdomen shining, sparsely and quite regularly punctate, at times

Legs moderate in length and stoutness, anterior femora feebly 

 sinuate and mutic in the sexes; anterior tibial spurs slightly dis- 

 similar in the sexes as well as the anterior tarsi.

 behind, arcuately and almost vertically declivous posteriorly. Abdo- 

 men moderately oblique, moderately convex, broadly and rather 

 slightly impressed on the first segment. Anterior tibiae with the 

 anterior spur slightly longer and a little stouter than the posterior; 

 anterior tarsi with the first joint rather simple at tip beneath, the 

 margino-apical tufts of spinules not conspicuous, groove somewhat 

 entire.
