For the opportunity of describing D. chrysopareia I ara indebted 

 to Mr. Salvia, who kindly forwarded to me his type specimen for the 

 purpose. The species has not been noted except from Guatemala 

 (and Me.xico?), but may not improbably be yet found in the Rocky 

 Mountains of the United States.* Mr. Salvin's specimen (No. xVxi) 

 was killed at Tactic, Vera Paz, Nov. 4, 1859.

Hah. Western province of U. S., and Mexico, into Guatemala. Migratory. 



I have never seen a specimen of this species in pure spring plu- 

 mage, and I am not sure that the throat ever becomes pure black as 

 in virens and its allies. Some specimens have the whole chin and 

 throat yellow — the feathers of the latter very indistinctly dusky in 

 the centre. 



' A specimen of this bird, or one very closely allied, is said to have beeu 

 recently collected near San Antonio, Texas, by Dr. A. T. Heermauu.
