180 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



The coloration of the series from Haines, Oregon, is much as in indigens 

 missoulae except that the buffy areas show a very weak dull olivaceous 

 tinge, while the caudal femora are dark brown on the external pagina and 

 distad, dull brick red elsewhere externally, but brighter red internally and 

 ventrad in males and in some rich ox-blood red there. Usually richly 

 colored the series show decided variability and the most recessive females 

 from Haugan, Montana, lack all red coloration and are as pale as the most 

 recessive females of indigens missoulae discussed under that race. 



Specimens Examined. — 19 males and 22 females. 



Montana: Haugan, VIII, 9, 1931, (Beamer, Anderson, Nottingham and 

 Peters), 17$, 18$, [Univ. of Kansas and Hebard Clns.]. Taft, VII, 1929,

The discovery of an exceptionally distinctive penis in males 

 of the present insect has come as a great surprise. Generally 

 the resemblance to indigens is very close, but now that a dis- 

 tinct species is known to be represented, the following incon- 

 spicuous but definite external differences are noted: tegmina 

 averaging broader in both sexes (with consequently narrower 

 interspace) and tapering more definitely in distal half to the 

 apex; male cerci proportionately smaller, not widened distad 

 (the latter a feature, however, which distinguishes indigens mis- 

 soulae as well), and subgenital plate with apex very briefly 

 (instead of prominently) produced. 



In the entire series of payettei the ventral surfaces of the 

 caudal femora are buffy, very faintly tinged with orange only in 

 males, whereas in the few males of indigens from the Payette 

 Lake region those areas are deep or bright nopal red. This fea- 

 ture is, however, known to be often unreliable and in indigens
