 Idaho and southern Montana. 



Since describing li. opimus^ I have been able to jompare it with the 

 tyi)es of Thomas's Pezotettix obesus and tind they are not distinct. The 

 species is very close to B,. pinf/uis, but differs from it in its markings, 

 particularly in its darker antennae, its much less developed median 

 abdominal stripe and its dift'erently colored hind tibiae, and also in the 

 more continuous and more developed median carina on pronotum and 

 abdomen, and the slightly dift'ering abdominal appendages of the male. 

 It is evidently the commonest and most widely spread of the species of 

 Bradynotes. _ ,^ ,
