This species is abundant in Colombia. 



I have one male specimen, nearly adult, without the frontal 

 spot of forehead, and the abdomen and flanks shining gold 

 with a lilac tinge on flanks. It looks as if it was an hybrid of 

 H. bonapartei and H. typica. I have also one specimen 

 from Colombia which I described in the Humming Bird, 

 1891, vol. i., p. 26, almost dark bluish-black, with the gular, 

 spot and uppertail-coverts dark silvery-green. Tail purplish- 

 black. \\'ings black. Maxilla black. Mandible flesh colour 

 at base. Rest black.

If it should prove a distinct species, I propose for it the 

 name of Hypochrysia nigra.
