370 Handlirsch — New Paleozoic Insects from the 



curved forward but backward. Radius composed of 3 long 

 forks. Media giving rise to but 3 brandies, directed back- 

 ward. Cubitus with its 6 branches occupying the whole free 

 posterior margin. Anal area very broad, its length only one 

 and a half times its breadth, filled by numerous simple veins. 

 This genus is sufficiently distinguished from all the Myla- 

 cridae known to me by the singular radius and the broad and 

 short anal area.

Shoulder very much produced. Subcosta composed of 3 

 branched veins, showing the tendency to curve toward the 

 radius and being therefore posteriorly concave. The radius 

 splits quite near the base into. 3 long branches, forming short 

 apical forks. The media traverses nearly the middle of the 

 wing, and gives rise to but 3 main branches directed obliquely 

 backward, the first of which rise's very near the base and makes 

 a long fork. The cubitus goes to the end of the posterior 

 margin and bends near to the media in the basal part, its first 

 branches being forked. The anal area is filled by about 12 

 veins. Length of the fossil 37™ m , of the anterior wing 30™™. 



Although the shape of this insect reminds one of Paro- 

 mylacris rotunda Scudder, with which Sellards has attempted 

 to identify it, the venation proves to be quite different. 



Holotype in Peabody Museum, Yale University, Cat. No. 62.
