Suhspeeific characters. — Similar to Basileuterus tristnatus auri- 

 cularis^ but under parts decidedly duller and paler, more buffy, less 

 yellowish ; the wings and tail more brightly colored. 



Measurements. — Male: Wing, 61-67 (average, 64.5); tail, 51-57 

 (54.5); bill, 10-11.5 (10.5); tarsus, 20-21.5 (21). Female: Wing, 

 57-63 (60.5) ; tail, 48-54 (51) ; bill, 9.5-10.5 (10) ; tarsus, 20-21 (20.5). 



Range. — Subtropical Zone, Western Andes of Colombia and west- 

 ern slope of the Andes of Ecuador. 



Remarks. — Early records for this form were placed under Basileu- 

 terus bivittatus by mistake. Most later records were j)laced under 

 B. tHsti^tus and B. auriculans. In 1908 Mr. Bangs gave the name 

 daedalus to the bird of western Colombia, comparing it with B. mela- 

 notis of Costa Rica and calling it a subspecies of that form. Doctor 

 Hellmayr, however, writing in 1911, still could find no difference 

 between birds from western Colombia on the one hand and those 

 from " Bogota," Ecuador, and Peru on the other, and unhesitatingly 

 placed them all with B. tristriatus. It remained for Doqjtor Chap-
