OETHOPTERA OF INDIANA. 277 



This is a common locust throughout the central and southern thirds 

 of the State; but is less numerous northward, where it seems to be 

 replaced in part by the next species, though it has been taken in 

 Starke and Lake counties. It frequents paths and bare places in dry 

 upland woodland pastures, especially those which include the slopes 

 of high hills, roadsides and stubble fields. In the northern (bounties 

 it is found most abundantly along the sandy edges of woodlands and 

 in old fields. In Crawford County mature specimens from eggs 

 hatched in spring, have been taken on June 35th; in Vigo County, 

 on June 30th. The males fly much farther than the females and on 

 arising from the ground emit a short and rather low rattling note. 

 The females are clumsy in their movements, and prefer, after being 

 flushed once or twice, to lie still when approached, as close to the 

 ground as possible, relying upon their protective coloration to prevent 

 discovery. 



Individuals of both this species and D. Carolina have, in late sum- 

 mer, a peculiar habit of sustaining themselves in the air, about three 

 feet above the ground, for several minutes. While poising in this 

 manner above one spot, they make a dry, rustling note, which is per- 

 haps a call to some nearby member of the opposite sex. 8. holli 

 ranges from New England to Georgia, Texas and Nebraska.
