It is remarkable that, with the exception of a single specimen taken at 

 Inscription Rock, N. Mex., during- the two seasons spent in Arizona and New 

 Mexico, this species should have been detected in but one locality, viz, in the 

 White Mountains, near Camp Apache, Ariz. Both seasons it was found in the 

 pine woods of the mountains, and apparently was one of the commonest 

 warblers that spend the summer here. I have little doubt but that, as 

 suggested by Dr. Coues, its range in summer embraces the high pine tracts 

 throughout Arizona and New Mexico. By July 10, the young, just from 

 the nest, were seen, and the old birds, in worn plumage, were busied con- 

 stantly in providing for the wants of their progeny. The coniferous trees 

 seemed to be alone frequented by them, and, in the tops of these, they 

 kept running swiftly over the smaller branches at the extremities of the 

 limbs, pursuing their prey on the wing. By the middle of August, they 

 had united in flocks, and, with other small insectivorous birds, appeared to 

 be lingering in the region preparatory to the southward migration. Their 

 preference for the pines was apparent, though occasionally found among 

 the oaks. Iris black ; bill and feet brown ; soles light yellow.
