dor and south to central Alaska, northeastern British Columbia and 

 across Canada to south-central Quebec, Newfoundland, and the Magda- 

 len Islands; it winters from southern Baja California and central 

 Mexico south to Peru, Colombia, and French Guiana. 



The 17 specimens of this race in the Smithsonian Institution collected 

 in Panama were taken on the Pacific slope from San Felix, Chiriqui, to 

 La Jagua in eastern Province of Panama, and on the Caribbean slope 

 from Almirante, Bocas del Toro, to Juan Mina, Rio Chagres, Canal 

 Zone. I also have specimens from Isla Cebaco and Isla Coiba, off the 

 Pacific Coast of Veraguas. M. E. Davidson collected a female at Puerto 

 Armuelles, Chiriqui, on November 27, 1929 (California Academy of 

 Science no. 32798).

 Alaska to western British Columbia. It winters from Mexico to Pan-

 and La Jagua and Chiman, Province of Panama, on the Pacific slope, 

 and at Juan Mina, Rio Chagres, Canal Zone, and Puerto Obaldia, San 

 Bias, on the Caribbean slope. All were females or immature males. 

 M. E. Davidson took a female at Puerto Armuelles, Chiriqui, on No- 

 vember 27, 1929 (California Academy of Science no. 32799) and Gris- 

 com identified specimens from Almirante, Bocas del Toro, as belonging 

 to this race (Peters, Bull. Mus. Comp. Zool., vol. 71, 1931, p. 333).
