Quite common, especially in the northern and central parts of the 
state, the long-winged variety appearing to predominate in the central 
part of the state, at least as far as my observations have extended. 
Group Oedipodini.

I have seen but a single specimen of this genus captured in Illinois ; 
it was taken in the extreme northern portion. I saw it but for a short 
time and am not positive as to the species.

The green variety ( virginiana ) is very common throughout the state, 
the female being apparently more abundant than the male ; on the 
other hand, the male of the dusky or brown variety ( infuscata ) appears 
to be much more abundant than the female of that variety. It is this 
male that greets us first in the spring with his crackling notes. Variety 
radiata is occasionally met with in the southern and central parts of 
the state, and probably in the northern sections also.
