Figure 53. — Localities for Priocnemis notha occidentis. 



lected together with these females make an uuquestionable association 

 of the sexes, but they are indistinguishable from males of the sub- 

 species navajo. Some additional males from the same general area 

 as the females represent additional specific localities, but are not 

 reported because they do not in themselves give proof of the distribu- 

 tion of the subspecies. 



This subspecies occurs in the Pacific States, mostly in the Transition 

 Zone. Adults occur mostly in middle and late summer and in early 

 faU.

Black. Apical half of mandible dusky rufous; wings rather weakly 

 infuscate; basal half of abdomen with obscure rufous stains.
