This handsome wood-brown locust occurs throughout Indiana, 

 but nowhere in numbers. It makes its home in thickets, in the 

 borders of open woods, in grassy plots alongside old rail fences, 

 and oftentimes along the borders of streams in woodland pastures, 

 but is seldom seen in damp localities. In such places its hues cor- 

 respond so closely with those of the dead leaves, fallen grass stems 

 and other surroundings that it is seldom the insect is noted until 

 it leaps clumsily to one side. Mature males have been taken in 

 Vigo County on -Tune 10th, an early date for locusts which have 

 hatched from the egg in spring. A single female with tegmina 

 reaching slightly beyond tip of abdomen was taken in Vigo Coun- 

 ty. The ordinary short-winged female is apt to be confused with 

 the brown females of DicJiromorpha viridis, but can be readily dis- 

 tinguished by the presence of the median carina of vertex, and the 

 curved lateral carinse of pronotum. 



The general range of C. conspersa is northern, extending as 

 far as known, from Maine north and west to the Severn Eiver,
