Hah. Southern Mexico, and throughout Central America to 

 Colombia, Venezuela, Ecuador, and N. Peru. 



There are slight variations in the shades of the blue and grey in 

 examples from different localities, but on the whole 1 am .satisfied 

 that the most reasonable plan is to refer all the birds from America 

 north of Panama to this species, which extends soutliwards to 

 Colombia and Western Ecuador.
