This is a locust of southern range which has been taken in Indiana 

 only in Crawford, Lawrence and Jennings counties. In the vicinity 

 of Wyandotte Cave, Crawford County, it is, in the latter half of 

 June and first part of July, one of the most common of the Oedi- 

 podinm. It occurs only on the uplands, where it frequents grain 

 fields, open bare places in the woods, roadsides and timothy mead- 

 ows. The male, when flushed, flies rapidly for a long distance, mak- 

 ing a low rattling note while in the air; the female, as in kindred 

 species, is too heavy bodied to take to wing gracefully, and therefore 

 more often moves by leaping. In the vicinity of North Vernon and 

 Mitchell, males only were seen. This locust probably occurs through- 

 out the southern third of the State, and perhaps winters in the 

 nymph stage. Its general range includes the southern United States 

 east of the Great Plains.
