THE EVENING HUMMING-BIRD. 



Trochilus vesper. LESSON. 



PLATE XXIV. MALE. 



L'Oiseau-mouche vesper, Ornismya vesper, Lesson Histoir* 

 Naturette des Oiseaux-mouches, pi. xix. p. 85 ; female, Les- 

 son's Continuation, pi. vi. 



THE present species has been figured by M. Lesson, 

 from specimens in the collection of the Jardin du Roi, 

 as different from the T. cyanopogon, to which it is 

 nearly allied, but differs much in size. The upper 

 parts are of a grayish green, of a more golden tinge on 

 the back and rump, but generally wanting the lustre 

 so prevalent in this race. The gorget is reddish violet, 

 with all its changes, and is surrounded on its lower 

 edge with a collar of grayish white. The breast and 

 belly are white, changing into gray on the flanks and 

 vent. The under tail-coverts are pure white. 



The female has been also figured and described for 

 the first time in the continuation of M. Lesson's Mono- 

 graph, which that ornithologist has again resumed; 

 the under parts are entirely white, and there is no 

 trace of the brilliant gorget belonging to the male.
