A. lieloisa has been included in works on North American birds pub- 

 lished since 1870, on the strength of a specimen erroneously identified 

 as this species, collected by Mr. J. H. Clark, of the United States and 

 Mexican Boundary Survey, at El Paso, Texas. t It is a species of east- 

 ern Mexico, where it inhabits the tropical coast district (and perhaps 

 the temperate slopes also), and may be expected to occur within our 

 limits along the lower llio Grande.
