Genera of Humming Birds. 109 



The differences between this species and all those included 

 amongst the genus Thalurania, are such, that I have not 

 hesitated in proposing a new genus for it. 



Genus L. Phaeoptila, Gould, Int. Troch., 1861, p. 169. 

 Doleromyia, Muls., Hist. Nat. Ois. Mou., t. i, p. 207.

Bill longer than the head, slightly curved, nostrils exposed, 

 wings long, nearly reaching the end of tail. Tail short, 

 slightly forked, medium rectrices shorter, lateral and outer- 

 most ones, slightly and gradually longer, all of them J^road. 

 Tarsi clothed. Sexes unadorned, nearlv alike.

Habitat. — Puebla, Oaxaca, (Mexico). 



Male. — Upperside bronzy-green, brownish on forehead. 

 Underside gray, washed with bronzy-green feathers on sides 

 •of breast and flanks. A tuft of white feathers on each side 

 of lower part of vent. A white spot behind the eyes. 

 Tail bronzy-gray. Wings silky-brown. Bill flesh colour, 

 with black tips. Feet black. 



Total length, 4m. Wing, 2^. Tail, if. Culmen, J. 



Female. — Same plumage as that of male, but paler gray 

 on underside, with just a few bronzy-green feathers on sides 

 -of breast. Lateral rectrices largely tipped with pale grav. 



I discovered this species in Oaxaca, South Mexico, and for 

 a long time, Gould himself thought that it was the female 

 of another species ; but having dissected a good many speci- 

 mens of both sexes, there is no doubt about it now. The 

 types of this species are now in the British Museum. (Ex 

 Gould Collection.)
