I have not seen specimens from the type locality, the only South American exam- 

 ples examined being from Bogota, Colombia, and Puerto Cabello, Venezuela. These 

 may or may not exactly agree with those from western Ecuador. The single Vene- 

 zuelan specimen seen agrees very closely with Costa Riean specimens ( T''. j. eoftiari- 

 cends), but has the pileum slightly darker and the under parts decidedly paler yellow.
