 ash on the crown; sides of the head ash, tinged with dusky beneath the eye (entire 

 head sometimes ash); chin and throat grayish-ash, gradually becoming darker to 

 the upper part ot the breast, where it becomes tinged with dark -ash ; sides of the 

 neck, breast, and body olive, like the back; rest of under parts light-yellow; a

 tract of pine forest, two or three specimens have been taken 

 within as many years. So far as I can learn, this species 

 has all the habits and motions of the two preceding. It 

 has no song, but utters the note qiieet often, and in a 

 sprightly tone, as it searches among the shrubbery for its 

 favorite food of spiders and small caterpillars. 



ICTERIA, ViEiLLOT. 



Icteria, Vieillot, Ois. Am. Sept. I., (1790) 85. 



Bill shorter than the head; broad at the base, but rapidly becoming compressed 

 or much higher than broad, with the ridge elevated and sharp from the very base 

 of the bill ; the upper outline much curved throughout ; the commissure less curved,
