tips on lateral and outermost rectrices are more conspicuous.

 of abdomen white, rest like the male.

This species is common in Guatemala. 



I have four specimens, three males and one female, collected 

 in Veragua bv Arce, which are very distinct in the colouration 

 of the throat and the underside. The throat is metallic lilac 

 with steel-blue reflections, the underside is gray or grayish- 

 white, washed sparingly with golden-green feathers on flanks, 

 remainder of plumage like //. pnllidiceps. The female is 

 coloured the same, excepting the throat, which is black 

 margined with white. If it should prove a distinct species, I 

 propose for it the name of Helioniaster veragjienjis.
