Head very small in front, blunt ; lateral ocelli close to 
the eyes, space between them with long hairs. 
Prothorax very large, extending back in a rounded form 
beyond the base of hind wings, the sides sharp pointed, the 
back very convex and wrinkled. 
Body and under parts densely clothed with hair. 
This very singular genus differs from all the Stridulantes 
in the size and shape of the prothorax; in the neuration 
of the elytra it is allied to Platy pleura (Amy^tand Serville) 
in the size of head and hairiness of body it approaches 
Carineta of the same authors. The Pupa, (fig. 5.) differs 
in the form of fore legs from those of the other Cicada.
