(1319) Adelomyia melanogenys melanogenys {Fraser). 

 Trochilus melanogenys Fraser, P. Z. S., 1840, p. 18 (Bogota). 



Our specimens are from the Subtropical Zone of the Eastern Andes. I 

 am unable to say what form is present at the head of the Magdalena Valley, 

 but a specimen from El Eden, above Ibagiie, on the Magdalena slopes of the 

 Central Andes, is typical of cervina, indicating the non-intergradation of 

 that form with melanogenys.

Common in the Subtropical Zone of the Western and Central Andes, 

 occurring on the eastern slope of that range.

Common in all three ranges. In the Western and Central Andes it is 

 restricted largely to the Temperate Zone, but in the Eastern Andes it occurs 

 chiefly in the Subtropical Zone — an unusual case in distribution. Males 

 from the three ranges agree in color. Those from the Central and Western 

 Andes agree in size, but in three specimens from the Western Andes the tail 

 appears to average shorter; but since our specimens from this region are in 

 molt, measurements taken from them are not satisfactory. 



Seven of eight immature females from the Central Andes have the white 

 throat-patch thickly spotted with blackish, while five of six immature 

 females from the Eastern Andes have this patch white without spots, and 

 in the sixth there are but a few spots near the breast. Nine specimens col- 

 lected by us, and sexed as females, have a throat-patch superficially resem- 

 bling that of the male in color, but somewhat smaller and less solid, the 

 feathers usually being whitish rather than grayish basally.
