370 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



A series of twenty six males and nineteen females was taken at 

 8500 feet in the Chiricahua Mountains on September 15, 1931, 

 by E. R. Tinkham for the author and seventeen males and six 

 females on July 8, 1932, by R. H. Beamer for the University of 

 Kansas. In all the caudal tibiae are glaucous. The penis is here 

 figured.

This species is widely distinct from M. indigens Scudder and 

 Scudder was certainly incorrect in erecting an " Indigens Series" 

 as that species is a member of the distinctive Oregonensis Group. 



Normally deep glaucous, the caudal tibiae are pink, usually of 

 a deep shade, in only sixteen females from the San Francisco 

 Mountains. Such dichromatism confined to the female sex 

 is known elsewhere only in snowii Scudder, saltator Scudder and 

 ascensus Scudder.

13 We are now certain that a female then recorded was incorrectly labelled 

 "Albuquerque, N. Mex.". The species does not occur east of the Coconino 

 Plateau in Arizona, and is replaced by snowii Scudder in the White Mountains 

 of this state.
