Floricola leocadiae is a northern form of F. constanti, and is entirely restricted to 

 Mexico, where it is found almost exclusively on the western side from Sonora in the 

 north to the Isthmus of Tehuantepec. 



Gould, who described the species as Heliomaster pinicola ^, says that it inhabits the 

 lofty pine-ridges of Northern Mexico ; but this statement is hardly correct, for we have 

 abundant evidence that its chief abode is at a low level, and even reaches the sea-coas 

 at Mazatlan, San Bias, Acapulco, and Tehuantepec. 



Our specimen from Alamos is quite young in its first plumage, and was shot on the 

 23rd May, 1888. One from San Bias is not fully grown, and was shot on 2nd May, 

 1889. A still younger bird from Bolanos was shot on 17th February, 1889. These 

 specimens indicate that the breeding-season extends over several months.

CYAXOPHAIA.

Compared with Floricola, which has a similarly denuded culmen and nasal covers, 

 this and the following genera have a much shorter, more curved, bill and longer tail in 

 proportion to their size. 



Cyanophaia has a distinctly forked tail, the lateral pair of rectrices being the longest. 



ITie genus itself contains three species, all of which are found in Colombia, but not 

 further south. Only one of these spreads over the State of Panama, and perhaps to 

 Costa Eica.
