The transverse thorax separates this genus ^rom Chrysop'ida ; 

 tlie filiform antennae and tootbed claws from CalUsina ; the 

 different form of the head from Scelodonla. 



The elytra in Rhyparida have each thirteen regular rows of 

 punctures, the first is as usual short, the ninth, tenth, and eleventh 

 begin in the space between the hinder portion of the humeral 

 callus and the middle of the disk, and are often confluent at

 and apex, its middle portion being lost in the thirteenth or marginal 

 stria. 



A. Thorax suhconic, viuch narrower than the elytra ; body brilliantly 



metallic.
