Tettigia hieroglyphica Say. July 3, 8, 12. 



This small cicada was quite common in bunch-grass at the Devil's 

 Hole and the Devil's Neck. In fonner years it has been much less

 forest insects, but this species is probably one of open plains. It 

 ranges from the foot-hills and plains of the southwestern states as

 It has not been taken in Illinois except in sand.
