Genus CYANOLESBIAb Stejneger.

Cyanolesbia emmae Berlepsch, Joum. fur Ornith., 1892, p. 452 (Antioquia); 

 Simon and Delmas, Ornis, 1901, p. 223 (La Graces); Ghapman, Bull. Am.

C[yanolesbia] cyanura emmae Hartert, Das Tierreich, 1900, p. 176. 



• Eustephanus burtoni Boucard: Similar to E. galeritus, but differs in having a 

 brilliant golden crown and the upper parts dark shining green (not bronze green) 

 with bluish reflections. 



''This Genus has been reviewed by Hartert (Nov. Zool., I, 1894, p. 47) and 

 (Nov. Zool., V, 1898, p. 514) and recently by Ghapman (Bull. Am. Mus. N. H., 

 XXXVI, 19 1 7, p. 308). I have adopted the views of the latter writer as his con- 

 clusions were based on the study of large series of all the forms (except berlepschi) 

 secured by Museum collectors and properly labelled with exact localities, etc. 



The following key is adopted from that given by Ghapman (I.e.) with the 

 addition of berlepschi:
