SYLVICOLID^—SETOPHAGIN^: FLY-CATCHING WABBLEBS. 313 



to be described,' four or five others maybe expected to occur over our Mexican border, — among 

 them the lovely Cardellma rubra, which is carmine red all over, with silky white ears; Seto- 

 phaga rm/kiata, very near S. picta ; and species of the genus Basileuterus. Our three genera 

 are readily distinguished, so far as our species are concerned, by coloration. 



Analysis of Genera. 



(f Black, wbite, and orange ; J brown, white, and yellow Setophaga 46 



J 5 Ashy, white, and carmine or rosy red Cardellina 45 



tf $ Without brown, red, or orange Myiodioctes 44 



44. MYIODIOCTES. (Grr. juvia, muia, a fly, and bianr-qs, dioktes, a pursuer.) Fly-catching 

 Warblers. BiUMuscicapine, though with lateral outlines a little concave, broad and depressed 

 at base, with many obvious rictal bristles reaching decidedly beyond the nostrils ; oulmen and 

 commissure nearly straight. Wings pointed, as in most SyhicoUdee, longer than tail ; 1st quill 

 longer than 5th, 3d equalling or exceeding 4th. Tail narrow, even or little rounded. Middle 

 toe without claw about three-fifths as long as tarsus. Tail unmarked, or with white blotches 

 as in Dendrceca. No red or flame-color ; always yellow below. Comprehends three species, 

 well distinguished among SylmicoUdm by the development of the rictal bristles and the depressed 

 shape of the bill, though these Muscicapine characters are not pushed to the extreme seen in 

 Setophaga. The tail is narrow, lacking the fan-shaped contour of that of Setophaga, and the feet 

 are stouter, with longer toes. In Cardellina, a near ally, the bill is narrow and conoidal, some- 

 what Parine in appearance, with curved culmen. In Basileuterus, and in fact in all the extra- 

 limital forms of the Fly-catching Warblers, the wing is rounded, with the 1st quill shorter than 



the 5th.

146. M. mitra'tus. (Lat. mife-ate, wearing a mitre, or other head-dress. Fig. 173.) Hooded Fly- 

 CATCHiNG Warbler. ,J, adult: Clear yellow-olive above; below, rich yellow, shaded with 



olive along the sides; whole head and neck pure black, en- 

 closing a broad golden mask across forehead and through eyes ; 

 _^,,^^^^ wings unmarked, glossed with olive; tail with large white 

 ' * " blotches >on the two or three outer pairs of feathers, as in 



Dend/rceca; bill black; feet flesh -colored. Length 5.00-5.25 ; 

 extent 8.50; wing about 3.75; tail about 2.25. 9, adult, 

 and young ^ , with the black restricted or interrupted, if not 

 wholly wanting, as it is in the earlier stages, when the parts 

 concerned are simply colored to correspond with the upper

of its extent if not in the purity of the black, by the female. Eastern U. S., strictly; N. 

 regularly to the Connecticut Valley ; W. to Kansas ; migratory ; breeds at large in its U. S. 

 range ; winters extralimital. A lovely bird, reminding one of the 



Kentucky warbler, common in the south in such brakes and bottoms ^_jg^jg^ ... ^ _ 



as the Kentucky haunts, rarer northward. Nest in bushes ; eggs 4, ^""^ '"" 



about 0.70 X 0.50, as usual white, reddish-sprinkled.
