290 SYNONYMY OF DENDRCECA MACULOSA 



DURING the vernal migrations, vast numbers of the Black- 

 polls enter the United States from their winter home in 

 South America, sometimes as early as February, and pass leis- 

 urely northward till some of them gain the uttermost Arctic 

 regions, while others, presumably later comers, are advised by 

 the progress of the season to nestle even short of the northern 

 border of our country. None are known as yet to come from 

 Mexico — a circumstance long favoring the general impression 

 that the species was a thoroughly Eastern one. Nevertheless, 

 we have ascertained that some of these birds advance west of the 

 Plains, along the eastern base of the Rocky Mountains, for they 

 have been found in May near Denver, Colorado, by Mr. H. W. 

 Henshaw, hovering about the rather debatable border-land of 

 the " Birds of the Colorado Valley ".
