 In general coloration this new species reminds one of some 

 species of the genera Tyranniscus and Leptopogon, but in 

 form it agrees closely with several species of the genus Och- 

 thceca, or more properly with those of the subgenus Meco- 

 cerculus. The bill is very slender and compressed, even a 

 little more so than in 0. setophagoides. The nostrils are of 

 precisely the same form as in the last-named species. The 

 bristles on the bill are very short and feeble. In colour 0. 

 consobrina is quite unlike any other species. The back is 

 of a very dark olive-green, the top of the head presenting a 

 slight suffusion of a dark ashy or blackish colour. The chin, 

 lores, and feathers round the eye, as well as an incon- 

 spicuous or ill-defiued superciliary stripe, appear dull whitish. 

 The ear-coverts are yellowish olive-green, bordered with 

 blackish on their tips. The whole under surface of the body 

 is of an intense sulphur-yellow, suffused or flammulated with 

 olive-green on the throat and breast. Wing and tail-feathers 

 blackish brown, the latter margined with olive-green. The 

 primaries, from the third to the sixth, are margined with rusty 

 yellowish from the base to a short distance from the tip, while 

 in the secondaries these margins do not begin until the
