Ergaticus, Barrp. (Page 237.) (Type Setophaga rubra, Sw.) 
Bill very short, and rather slender; the culmen, however, and commissure 
curved from the base. Rictal bristles well developed, reaching midway from 
nostril to tip. Wings rather shorter than the nearly even, somewhat rounded 
tail; the 3d and 4th quills about equal; the Ist a little shorter than the 6th. 
Tarsi lengthened ; the middle toe without claw half the tarsus. 
This form differs from typical Cardellina in much slenderer, 
though somewhat similarly shaped bill, greater development of rictal 
bristles, considerably shorter and more rounded wings, ete. In some 
respects it resembles the section [diotes of Basileuterus, but may 
properly be separated.
