Central America (Guatemala, Honduras, Nicaragua, and Costa Rica). 



Although the name cyanogenys was based by Dr. Sharpe on what 

 was clearlj' an unusual development of the lighter colored triangular 

 malar patch, and is therefore misleading, it is nevertheless necessary 

 to retain it for the southern form, since it is the only one based on 

 the Central American bird. In most specimens this malar patch is 

 obsolete, sometimes quite obliterated, and in no specimen is it blue in 

 color, but dull gray. In none of the Central American birds is it nearly 

 so distinct as in an example of true P. mexicanus from Mirador," State 

 of Vera Cruz, Mexico, in which it is very conspicuous, its color being 

 clear ash gi'ay.
