This is a common locust throughout the central and southern 

 thirds of Indiana, but much less numerous northward, where it 



seems to be replaced in part by S. 

 wyomingianum, though it has been 

 taken in Starke and Lake counties. 

 It frequents paths and bare places in 

 dry upland woodland pastures, espe- 

 cially those which include the slopes 

 of high hills, roadsides and stubble 

 fields. In the northern counties 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 

 25th; 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. 



The known range of AS', bolli is a wide one, extending from 

 Maine and southern Ontario, west to Awerne, Manitoba and Colo- 

 rado, and south and southwest to northern Florida, Oklahoma,, 

 central Texas and Las Vegas, New Mexico. In Florida it appears; 

 to be scarce, the only definite known locality being Tallahassee, 

 the other records from the northern part of the State being based 

 on 8. crepitans. In Ontario Walker (1898, 261) found it common
