REHN AND HEBARD 171 



The Antillean records and those from Panama apply to a closely 

 allied but distinct species C. cinereus, while those from Mexico 

 may be in part correct, as the present species certainly inhabits 

 the northern portion of that country; the South American rec- 

 ords, however, belong either to the above mentioned or still 

 another species. 



The tegmina normally surpass the tips of the caudal femora 

 when in repose; no brachypterous condition exists in this insect 

 and only very occasional specimens have the tegmina barely 

 reaching the extremities of the caudal femora. This latter con- 

 dition is found only in rare specimens from northern localities 

 and in western series approaching C. f. vicinus. 



The male cerci in the present species are usually bright green; 

 in drying some specimens, as in the other species of the genus, 

 lose all of their normal green general coloration, becoming a 

 uniform straw color. The genicular areas of the caudal femora 

 are not darkened; the genicular lobes of the same are normally 

 bispinose; the ventro-external margins of the caudal femora are 

 normally unarmed, verj' small (usually microscopic) spines are 

 present in two hundred and eight perfect specimens examined as 

 follows : 



Number of spines, 0-0 0-1 1-1 1-2 2-2 



Number of specimens, 182 19 5 1 1 



This shows 12.5 %of the material to have these margins armed, 

 geographic distribution apparently having no effect on this con- 

 dition in the present species. In the specimen having the ventro- 

 external margins of the caudal femora armed with 2 and 2 sjoines, 

 one of the ventro-internal margins is also furnished with a single 

 minute spine, this is also found in a single specimen having the 

 ventro-external margins unarmed. 



The ovipositor length is as follows: Bothwell, Prince Edward 

 Island, 8-9.2; Northeast Harbor, Maine, 7-7.8; Fredericksburg, 

 Virginia, 8-9.3; Jacksonville, Florida, 7.3-8.3; West Point, Ne- 

 braska, 9.2-9.6; Pinebluft", Wyoming, 8.3-9.9; Carrizo Springs. 

 Texas, 8.6-9.7; Jemez Hot Springs, New Mexico, ^'^ 8.6-9.4 mm. 



The present species is found in the United States from the 

 Atlantic to the Pacific, the typical form being supplanted by a 



1' These specimens are intermediate between the eastern and western races 

 of this species.
