Genus MITREPHORI7S, Sclater. 



MUrcphorus, Sclateii, P. Z. S. T859, 44. (Tyi)f, M. phfvorrrcus.) 



Gen'. Char. Similar in j^eneral character to M. empidonax, but with fulvous, fulvous-olive 

 aud rufous tints, instead of clear olive, gray, white, 

 and sulphur-yellow. Head crested ; bristles of gape 

 reaching nearly to tip of bill. Feet very weak. 



The type of this genus (3/. phccoccrcus) 

 is (|uite different in form from Umpuhnax, 

 the nearest North American ally, but both 

 M. j^rdlcsccns and fu I v if rons could with little 

 violence be placed in it. There is no posi- 

 tive character to separate the latter from 

 the average of species of Empidonax, ex- 

 cept it be the color. The crest is not at all conspicuous, nor is there any 

 appreciable difference of form ; while in the form of the bill these species 

 are much nearer Empiilonax than Mitrephorus. The legs, however, are 

 weaker, and the rictal bristles longer. 



There are two forms of the group, as defined by Sclater : one embracing 

 £. phaveoruSy Sclater (Mexico and Guatemala), and E. aurantiiventris, Lawr. 

 (Costa Eica) ; the other E. fulvifrons, Giraud, and pallcsccns, Coues. The 

 differences between the last two, which are probably merely races of one 

 species, may be expressed as follows : — , 



M. fulviirons. Olivaceous above ; beneath ochraceous-fulvous ; darkest on 

 the breast, paler on throat and crissum. External edge of outer tail-feathers 

 whitish. 



Olive of back fulvous ; under parts decided ochrey-fulvous. Wing-bands 

 tinged with ochraceous; wing rather pointed. First quill equal to sixth; 

 third, longest. Whig, 2.65; tail, 2.40 ; tarsus, .61. Hah. Northern Mexico. 



var. fulvi fro ns} 

 Olive of back grayish ; beneath obscurely ochrey-fulvous and much paler : 

 wing-bands grayish-white ; wing rather rounded. First quill shorter than 

 sixth ; fourth longest. Length, 4.75 ; wing, 2.15 ; tail, 2.00 ; tarsus, .55. 

 Hub. Arizona x&t. pall esc ens.
