218 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



the coast of the Carohnas to be immature as late as early Septem- 

 ber. Among the nearly adult females taken there, the ovipos- 

 itor ranges from 13.7 to 14.9 mm., which, with our adult series 

 from Thomasville, Georgia, shows that over the lowlands of 

 the southeastern United States the ovipositor averages very 

 long. Males from this region also show the cerci averaging 

 slightly longer and more slender than elsewhere in the distribu- 

 tion of the insect, but, when the variation in almost every large 

 series is noted, the above results, though showing very possibly 

 an incipient geographic differentiation, are by no means sufficient 

 to warrant the recognition of a geographic race. Individuals 

 from Texas and Okhihoma average much the largest of any 

 specimens before us. 



The species is widely and generally distributed over the prairies 

 of the middle west, east of this its distribution appears to be more 

 or less discontinuous, the insect preferring sandy or other areas 

 of poor soil such as the serpentine outcrops in Pennsylvania. 



The present species is known on the Atlantic coast from the 

 East Plains and Brown's Mills, New Jersey, southward to Yemas- 

 see. South Carolina and Thomasville, Georgia, and is probably 

 distributed, except in the northern portion of this region, west- 

 ward to the base of the Appalachians. The northernmost points 

 of distribution are Toronto, Ontario; the Red River, Aweme and 

 the Souris River, Manitoba, and Moose Jaw, Saskatchewan. In 

 western distribution it has been found along the Yellowstone 

 River as far as Livingston, Montana, and has been taken in 

 Colorado at Fort Collins and Manitou. The most southwestern 

 records are Springer, New Mexico, and Amarillo and Dallas, 

 Texas.
