This species, though detected at several points west of the Rocky 

 Mountains, seems to be quite rare. It was never seen by us in Utah, 

 where, however, Mr. Allen considered it quite common in the neighborhood 

 of Ogden in September. In California, it was taken during the summer in 

 numbers in the Sierra Nevada near Lake Tahoe. In Arizona, I do not think 

 it occurs, save as a migrant. About Camp Crittenden, in the extreme south- 

 ern portion of the Territory, it was quite common during the last few days 

 of August and the first of September. They appeared to keep constantly 

 in the low trees and bushes, and were very active in their pursuit of insects. 



Specimens collected from this locality show some slight peculiarities 

 of coloration in the restriction of the yellow of the throat and the more 

 decided ashy tinge of the sides of the head.
