to silvery pubescence ; the metathorax much more thickly 

 than the mesothorax ; strongly (especially the pleural) 

 punctured ; the scutellum not so strongly as the mesonotum. 

 Metathorax shorter than the mesothorax, broader than 

 long, almost rounded at the apex, coarsely rugose, running 

 into reticulations ; the apex strongly, nearly transversely 

 striolated. Abdomen as long as the head and thorax 

 united ; shining, obscurely shagreened ; the segments edged 

 with silvery bands of pubescence, interrupted in the middle ; 

 the apex rather acuminate ; pygidial area very shining, 

 margined along the side, sparsely punctured. Femora 

 sparsely, tibiae and tarsi densely covered with white silvery 

 hair ; the spines and claws pale ferruginous ; the calcaria 

 blackish, reddish on the lower side. The second cubital 

 cellule is about one-fourth longer than the third, the latter 

 at the top being somewhat longer than the space bounded 

 by t|je recurrent nervures. The apex of the radial cellule 

 is narrow, not sharply angled on the lower part, but rather 

 rounded, and reaches near to the apex of the third cubital. 

 The appendicular cellule is narrow, but distinct.
