A not uncommon inhabitant of the Temperate Zone of the Eastern 

 Andes, descending to the upper border of the Subtropical Zone. Specimens 

 from Chipaque on the eastern slope are paler than those from the more 

 humid western slope at El Pinon, which are quite as richly colored as M. 

 chrysops, but our series is not large enough to prove that the variations 

 observed are racial.

An abundant inhabitant of the Temperate Zone in the Central and 

 Western Andes. In crossing the Central range it was first met with at about 

 9000 feet on the western slope at the upper border of the Subtropical Zone. 

 After crossing the Quindio Pass its numbers increased and in the valleys of 

 the Tochicito and Toche it was abundant as low as 8000 feet. Although 

 this species obviously represents M. ornatus, our series of twenty-seven 

 specimens shows no indication of intergradation with that species through 

 the presence of white in the ocular region. As remarked, however, under 

 that species, ornatus from the humid Temperate Zone at El Pinon has the 

 forehead and underparts as richly colored as chrysops.
