Type locality. — Little Spring, north base of San Francisco Moun- 

 tain, Coconino County, Ariz. ; altitude 8,250 feet. 



Type specimen. — Adult male. No. 18684, United States National 

 Museum (Biological Survey collection), collected at San Francisco

 Mexico, Arizona, and northern Mexico to the Pacific coast of southern 

 California and northern Lower California, and northwestward into

 been wholly worked out. Specimens have been taken in the south- 

 western part of California, as well as in Nevada, eastern Oregon, 

 and southeastern Washington. 



Diagnosis. — Color above richer and less pallid than in the typical
