MYIOCHANES BRACHYTARSUS (Sclater). 

 SHORT-LEGGED WOOD PEWEE. 



Adults (sexes alike). — Above plain olive, more or less darker 

 (sometimes sooty blackish) on pileum, lighter and more brownish 

 on rump and upper tail-coverts; tail dusky grayish brown, the outer 

 webs of rect rices passing into grayish olive on edges; wings dusk}^, 

 the middle and greater coverts margined terminally with pale gray 

 or grayish white (more or less buffy in immature birds), the sec- 

 ondaries edged (except basally) with the same; sides of head and 

 neck similar in color to back, etc., the lores at least partly grayish 

 white; chin, throat, median line of chest, median portion of breast, 

 abdomen, and under tail-coverts varying from pale yellow (nearly 

 primrose) to white,*^ the sides of chest and breast and sides plain 

 light grayish olive or gray; maxilla blackish brown or brownish 

 black; iris brown; legs and feet dusky brown or blackish. 



Young. — Somewhat like adults, but general color of upper parts 

 duller, less olivaceous, the feathers of pileum, hindneck, back, etc., 

 terminally margined or narrowly tipped with buffy whitish, those of 

 rump, together with upper tail-coverts and lesser wing-coverts, more 

 broadly tipped with pale cinnamon-buff, middle and greater coverts 

 broadly tipped with buff, cinnamon-buff, or pale cinnamon (forming 

 two conspicuous bands), and secondaries broadly edged (except 

 basally) with the same. 



Adult male.— Length (skins) , 125-145 (135) ; wing, 67.5-76.5 (72.9) ; 

 tail, 56-65.5 (61.1); exposed culmen, 13-15.5 (14.1); tarsus, 13-14.5 

 (13.7); middle toe, 7-8.5 (7.7).^^ 



« The specimens from Boquete cited imder this name by Mr. Bangs I find to be 

 referable to H. r. richardsonii. 



Some Costa Rican specimens which I have tentatively referred to this form are very 

 puzzling, and I believe that they are really something different. They have. a very 

 dark coloration, the pileum being nearly black. But for their very different wing- 

 formula, which is quite that of M. virens and 31. richardsonii, these specimens resemble 

 very closely darker colored examples of M. brachy tarsus. 



bin the bibliography of Dr. Sclater's publications (Bull. U. S. Nat. Mus., no. 49)^ 

 p. 85, the type is said to be in the Sclater collection in the British Museum, and the type 

 from " Mexico"; in Cat. Am. Birds, 1862, 231, the type locality is said to be Orizaba.
