black, except at the base below, or else black at tip ; all the feathers 

 with a central spot of ochraceous-yellowish, bordered by blackish, 

 traces of these spots occasionally visible in adults. 



Myiadestes venezuelensis. 



Mi/iadestes venezuelensis, Sclatek, Ann. Mag. Nat. Hist. 2d ser. XVII, 

 468.— Ib. p. Z. S. 1857, 6; 1860, 64 (Ecuador).— Ib. Catal. 1861, 

 48, no. 290 (Bogota). 



Hab. Venezuela, Bogota, and Ecuador. 



(No. 32,513.) First quill about two-fifths the longest ; nearly half the 2d, 

 which is rather shorter than 7th ; 4th and 5th longest. 



Above dark rusty brown, brightest towards rump. Forehead (shading off 

 into tlie olivaceous rufous of cap), cheeks, and under parts, including lining 

 of wings and axillars, dark slate color, becoming paler behind ; the tibiae, 

 flanks and end of orissum somewhat tinged with olivaceous rufous (some- 

 times scarcely appreciable). Lores dusky. As in most species, a band of 

 light fulvous at bases of quills, distinctly seen on the inside of wing ; scarcely 

 appreciable externally, and followed by a dusky bar. Middle tail feathers 

 somewhat like back, but with a purplish tinge ; other feathers purplish-black, 

 the outermost gray for most of outer web, the next to a less extent, both with 

 a patch of white at end of inner web. Bill dusky above, yellow beneath ; 

 feet yellow. 



(No. 32,513.) Total length, 7.20 ; wing, 3.30 ; tail, 3.25 ; difference of 10th 

 and longest quills, .70 ; exposed portion of 1st primary, .95, of 2d, 2.16, of 

 longest (4th) (measured from exposed base of 1st primary), 2.60 ; length of 

 bill from forehead, .55, from nostril, .26, along gape, .69 ; tarsus, .80; middle 

 toe and claw, .75, claw alone, .21 ; hind toe and claw, .56, claw alone, .23. 



This species agrees suflciently well in form with the Mexican, 

 but ha,s shorter and more rounded wings ; a proportionally longer 

 first primary, and perhaps a more even tail. The yellow mandible, 

 darker rufous of back extending to head, dark slate of throat, and 

 absence of white or dark lines about the head readily distinguish it 

 from 31. obscurus, most nearly allied in color.
