Male.—Th& only difference between this species and A. 

 graysoni is in its much smaller size, the tips of rectrices which 

 are metallic bronze or metallic bronze-green, and the forehead 

 of the same colour as the rest of the upperside. 



The female is slightly paler than the male.

I think that the discoverer of this species is Delattre, who 

 communicated it to Lesson. 



I have some specimens of this species collected by 

 Sumichrast, at Tehuantepec, Mexico, and others which I 

 collected at Punta-Arenas, Costa Rica.
