If 6766 from Villavicencio belongs to this species, this species is found both 
east and west of the Andes. But it is a small specimen and the positive identifica- 
tion across the Andes may be left till larger specimens are available for examination. 
Meek & Hildebrand found this species to be abundant on both slopes of the 
central range in Panama.
