Idiotes, Baird. (See page 237.) (Type Setophaga ruji/rons, Sw.) 



Bill broad at base, but quite deep, being nearly as high as wide ; the culmen 

 ourvtiil gently from the base, the lateral outlines straight ; the bristles only 

 underate, reaching half way from nostrils to tip of bilf. Tail lengthened, 

 lunger than the short wings, and considerably graduated ; the 4th quill 

 longest ; the Ist not longer than the 9th. Toes rather lengthened. 



The species of this group have generally been placed in Basi" 

 leulerus. They, however, differ in having the bill narrower at base, 

 and proportionally deejior, the bristles less developed, although the 

 culmen is as much curved. The wings are much shorter, and the 

 tail proportionally longer and more rounded, considerably exceeding 

 the tail instead of being about equal to it. The transition, how- 

 ever, is quite gradual through B. belli and J. mesochrysus, which, to 

 some extent, combines the characters of both.
