 (Substitute for Lanio Vieillot. ) 



Medium sized to rather large Tanagers, with the maxilla compressed 

 and abruptly hooked at tip, the tomium with a conspicuous median 

 tooth; adult males with the plumage mainly black and yellow. 



Bill nearly as long as the head, much compressed and strongly hooked 

 terminally, the maxillary tomium with a conspicuous tooth-like pro- 

 jection about, or a little less than, one-third the distance toward base; 

 mandibular tomium obliquely beveled at tip, then faintly concave to 

 beneath the maxillary tooth, then slightly arched for about the basal 

 two-thirds; culmen nearly as long as tarsus, nearly or quite sti'aight 

 for most of its length; gonys decidedly shorter than length of maxilla 

 from nostril. Nostril partly concealed by distinct antrorse frontal 

 bristles, rather large, nearly circular. Rictal bristles conspicuous; 

 mental bristles distinct, strongly recurved. Wing about £ve and one- 

 third to five and three-fourths times as long as the short tarsus, rounded 

 (eighth to fifth primaries longest, ninth not longer than fourth); pri- 

 maries exceeding secondaries by -about length of tarsus or a little 

 more. Tail shorter than wing by not more (usually much less) than 

 length of tarsus, slightly rounded, the rectrices rather broad, with 

 rounded or very slightly pointed tips. Legs and feet comparatively 

 very weak; tarsus little if any longer than exposed culmen; middle 

 toe with claw about as long as tarsus; lateral claws falling a little 

 short of base of middle claw; hind claw shorter than its digit. 



Coloration. — Adult males with head, wings, and tail black, the rest 

 of the plumage mainly yellowish, with a white patch between scapu- 

 lars and lesser wing-coverts; females brownish above, paler, some- 

 timeh tinged with yellow below, the throat sometimes grayish or 

 whitish.
