Female. — Probably like the male, but paler in colouration. 

 Contrary to the opinion of many authors, I think that the 

 female of this species is not buff underside. However, 

 until I can ascertain if I am right or wrong, I shall give the 

 description of the bird which I have in my collection, sent to 

 me by Arce, as a female.

 Median rectrices bronze-green. Laterals bronze-green at base, 

 passing to bluish-black with broad white tips on the two 

 outermost ones. Line behind the eye white. Ear-coverts 

 black. Underside reddish-buff. Bill black. 



This rare species was discovered by Mr. Warzewicz, on the 

 Volcano of Chiriqui, Veragua.
