is quite straight ia Scytinoptera, is bent sharply into a very noticeable bay or 

 hollow, concave to the costal margin, a little beyond the middle of the wing, in 

 the new genus. Terminal branchings of M and Cui two each, connected by a 

 single cross-vein much as in Scytinoptera, but JM3+4 and Cuia lie closer together. 

 Clavus (missing iu Scytinoptera) of fairly typical Scytinopterid type, but 2A

Ues very close to the basal posterior mai-gin. and appears also to run close along- 

 side the distal posterior margin of the clavus, thus showing a very early stage 

 in the evolution of the true claval Y-vein found in the Fulgoroidea. Shape of 

 wing somewhat different from that of Scytinoptera, the costal area being about 

 equally wide throughout, and the apex much less broadly rounded.

A complete tegmen, except for slight damage at the base of the clavus and 

 also at end of Ei; of tough consistency, strongly granulated all over. All the 

 main veins clearly marked, but the distal branchings somewhat fainter. The im-
