Inhabits the Subtropical Zone of the Eastern Andes in the Bogota 

 region and northward at least to Bucaramanga. 



The distribution of the forms of the genus Cyanolesbia in Colombia and 

 the characters they exhibit, present a problem in regard to their relation- 

 ships which I confess I am unable satisfactorily to solve. All are confined 

 to the Subtropical Zone, and the occurrence of the green-throated C. emmas 

 and the purple-throated C. ccelestis in this zone, in the Western Andes, in 

 one instance at localities practically within sight of each other, is evidence 

 of the specific distinctness of these forms. At no other place, it must be 

 stated, have we found the green and the blue-throated forms so nearly 

 associated; but on the other hand, om* large series of males do not show one 

 intermediate specimen. Thus not one of thirteen males of emmcB from 

 western Colombia, and twenty-six males of caudata from Merida, shows 

 any trace of a purple throat-patch. With equal truth it may be said that 

 twenty-two males of C. mocoa, eight of ccelestis, five of kingi, and two of 

 margarethcB, all possess the purple throat-patch.' 



^ Hartert, in his first review (Nov. Zool., I, 1894, p. 47) of this genus reached conclosions in regard 

 to the relationships of its forms essentially similar to those I here present; but subsequently (Nov. 

 Zool., V, 1898, p. 514) he treated them all, except berlepschi and ctEUstis, as subspecies. Lack of proper 

 data accompanying his species prevented Hartert in some instances from giving correct ranges. For 

 the same reason his remarks in regard to specimens of emmsE with "blue" on the throat lose point 

 since it is not impossible that these birds came from the range of mocoa and hence should be referred 

 to that species. 



Of caudata he states that not one among about one hundred adult males from Merida showed 

 "even an indication of a blue spot on the throat." Nevertheless, he treats this bird as a subspecies 

 of kingil
