MNIOTILTID.E: AMERICAN WARBLERS. 345 



specimens have the head plain red, the cap sooty-black. There is much difference in the char- 

 acter of the white on nape. Length 5.00; wing 2.66; tail 2.50; tarsus 0.66; bill 0.33, 

 quite different in shape from that of Setophaga. Young, newly fledged : Ash of upper parts 

 much shaded with brown, as is white of under parts. Rump snowy-white, as in the adult, but 

 the nuchal patch obscure or inappreciable. Wings and tail as in the adult, but with browner 

 edgings. Black cap restricted to top of head, and of a dull sooty cast. Red parts of the 

 adult, including those parts of side of head which are occupied in the adult with the extension 

 of the black cap, dull grayish -brown, tinged or irregularly slashed with red, especially on fore- 

 head and throat. Bill light brown ; feet pale. Arizona, New Mexico, and doubtless Texas ; 

 S. to Guatemala; common in pineries of southern Arizona, especially during migration, and 

 also breeding there in mountains up to 7,000 feet. May and June. Nest on ground, under a 

 tuft of grass, of hay and leaves; eggs 4, pure white, fully speckled and blotched. 

 ERGA'TICUS. (Gr. (pyariKos, ergatikos, able or willing to work, industrious, diligent, ac- 

 tive.) Carmine Fly-catchixg Warblers. Bill Parine in appearance, as in Cardellinaj 

 and other characters much as in that genus, of which the present has often been considered a 

 subgenus. Tail about equal to the wings, both lengthened; 1st quill about equal to the 6th. 

 Rictus well bristled, as in other genera of this group. Plumage nearly unicolor, rich red, with 

 white auriculars ; sexes alike. One species. 



E. ru'ber. (Za^., red.) Carmine Fly-catching Warbler. Adult $ 9 : Rich carmine 

 red, obscured on the back; ear-coverts silvery- white; wing- and tail-feathers dusky, edged 

 externally with reddish ; middle wing-coverts mostly pink or rosy white. Young simply rusty 

 brown, paler and more rufous below ; but known by the silver ears, which show plainly with 

 the first feathering. Length 4.75; wing 2.40; tail 2.50, graduated 0.20; tarsus 0.75. A 

 very beautiful extralimital species, inhabiting the highlands of Mexico, like Setophaga miniata, 

 and believed to extend N. to Texas. Not in either of the Coues Check Lists ; admitted to the 

 Sd ed. of the Key, 1887, p. 870; A. 0. U. Lists, 1886 and 1895, No. [691], on the authority 



of GiRAUD. 



BASILEU'TERUS. (Apparently the comparative degree of QaaiXevros, hasileutos, kingly, 

 regal, regnant, from fiaaiXevs, basileiis, a king, monarch.) Crowned Fly-catching War- 

 blers. Bill Muscicapine, more or less widened at base, as in Setophaga and Wilsonia, but 

 deep, with gently curved culmen ; rictal bristles variable, but obvious. Wings rather short, 

 more or less rounded ; 1st quill equal to 7th, or still shorter. Tail about equal to or longer 

 tlian wings with narrow feathers unmarked in color. Coloration olivaceous and yellow, the 

 head (in our species) marked with black stripes bordering a yellow, rufous, or orange-brown 

 field, strikingly after the pattern of Siurus auricapillus. Sexes alike. A large genus of tropi- 

 cal and subtropical American species, two of which reach the Mexican border of Texas. These 

 represent Tesi)ecti\e\y Basileuterus proper of Cabanis, 1848, and the subgenus Idiotes Baird, 

 1865. 



Anahj/tis of Specie.i. 

 Top of head with black stripes bordering a yellow or orange-brown median one ; no yeUow superciliary line or any 



chestnut on side of head ciilkirorus 



Top of head with black stripes bordering a rufous median one ; front black, a bright yellow superciliary line, and 



sides of head chestnut belli 



B. culici'vorus. (Lat., gnat-eating ; culex, a gnat, midge, mosquito ; rorare, to devour.) 

 Brasher's Ply-catching Warbler. Adult ^ 9 : Above, grayish -olive, or olivaceous- 

 ash, fif variable shade with age or season. Below, yellow, shaded with olive on sides. Crown 

 yellow, varying to orange-brown, rufous, or somewhat greenish-yellow, bordered on each side 

 with a stripe of black ; some dusky loral or ocular markings, not well defined, but no bright 

 yellow or chestnut on sides of head. No special markings of wings or tail. Length 5.00 or 

 less; wing 2.40 or less; tail 2.00-2.20, graduated 0.15; bill 0.50; tarsus 0.7.'>. Central
