ascending anteriorly. Mesosternal lobes separated by a s])ace much 

 broader than long, the metasternal lobes by a sj^ace broader than long 

 (female) or about as broad as long (male). The tegmina are generally 

 abortive (female) or well developed (male). The scapular area is 

 unusually expanded, especially near and beyond the middle in the 

 male (and in the female to a less extent when the tegmina are not 

 abortive), and is filled with a series of strong oblique cross-veins. The 

 discoidal is as broad as the ulnar area, and the intercalary vein is 

 present. The posterior femora are rather slender or moderately robust 

 and more or less distinctly banded above. The posterior tibiae have 

 the apical spurs on the inside about equal. 



This North American genus contains two species, one from the 

 north-eastern and one from the north-western United States.
