THEENETES. — PHAETHOENIS. 317 



Veraguas to Gould, who figured them in his ' Monograph of the Trochilidae.' The 

 bird is now known to be not uncommon in some parts of the State of Panama and also 

 in Costa Rica. An allied species of Threnetes from Ecuador was described by Gould as 

 T.fraseri; this has been united to T. rucheri by some writers, but seems to be distinct. 

 It has a smaller cinnamon patch on the breast, is greyer on the under surface, and has 

 darker median rectrices.

This genus, consisting of about seventeen species, is spread over the lowland forests 

 of the greater portion of Tropical America, none of the species ascending the mountains 

 to any considerable height. Of the three main sections into which the genus is 

 divisible, two only are represented within our limits, each by a single species. 

 P. emilice, which is closely allied to P. guyi, reaches Costa Eica, and P. longirostris 

 occurs throughout Central America and in Eastern Mexico as far as the middle of the 

 State of Vera Cruz. The section of Phaethornis represented by the latter bird is 

 remarkable for the form of the tail, which is cuneate, the central rectrices being 

 elongated, and the rest gradually reduced in length towards the outside, and all of 

 them conspicuously tipped with white or buff. The bill is long and curved, and no 

 glittering marks enter into the coloration of the plumage.
