The brilliant group of " Blue Creepers " which constitute this 

 genus pervades the tropics of America from Cuba and Mexico to 

 {Southern Brazil and Bolivia. Four forms only seem to me worthy 

 of specific separation, and two of these are but slightly different 

 representatives of the same structure. The Ccereba are at once 

 known from their relatives of the same group by the deep blue 

 colour of the males and the slender Creeper-like bill. They are low- 

 ranging birds, not apparently ascending to high elevations, and fre- 

 quent the edge? of the forests and the trees and shrubs of the more 

 open districts, where they arc perpetually in search of their insect 

 food among the branches ; but they also eat ripe fruit.
