210 Rldgimy — Neiv Genera of Tyrannidse, Pipridse, Cotmgidse. 



and longer than lateral toes (without claws) ; tail relatively shorter (decid- 

 edly shorter than length of wing from bend to end of secondaries), and 

 outermost (tenth) primary longer than fifth. 



Ti/pe, Ampelis c.mctus Tschudi = Slictornis cinctus. 



{Xtikt6s, marked, spotted; 6pvis, bird.) 



The species designated as the type of this new genus I remove from 

 Ampellon Cabanis, which according to my views contains only two of the 

 species there placed in Vol. XIV of the " Catalogue of Birds in the British 

 Museum " (pp. 373-376), the remaining one {Ampelis arcuaia Lafresnaye) 

 belonging to the genus Euchlornis DeFilippi. 



Idiotriccus gen. nov. {Cotmgidse.) 



Superficially resembling the Tyrannine genus Pognnntriccus Cabanis and 

 Heine, but tarsal envelope pycnaspidean, with the scutella on lower por- 

 tion of both acrotarsium and planta tarsi roughened, subtuberculate ; bill 

 broader basally and more depressed ; nostrils surrounded by membrane ; 

 bristles of frontal antipe, rictus, and chin less developed. 



Tgpe, Fognvotriccus zeledovi Lawrence = Idiotriccus zeledoni. 



("iStos, distinct ; tpIkkos, a small bird.) 



Elainopsis gen. nov. (Cotingidse.) 



Superficially resembling the Tyrannine genus Elainea Sundevall, but 

 tarsal envelope pycnaspidean and basal phalanx of middle toe wholly 

 united to outer toe. 



Type, Elainea elegnns Pelzeln (= Muscicapa gaimardi D'Orbigny?). 



{Elainea, a genus of Tyrannida? ; + S'/'ts, aspect.) 



Species: Elainopsis elegans (Pelzeln). 



Microtriccus gen. nov. {Cotingidse.) 



Similar to Tgrannulus Vieillot, but bill relatively stouter, with culmen 

 much more decidedly curved, tarsus relatively shorter, tail relatively much 

 shorter (much less than two-thirds as long as wing), pileum not crested 

 and without yellow, and wings without whitish bands. 



Tgpe, Tgrannulus semiflavus Sclater and Salvin. 



(MiKp6s, small ; tpIkkos, a small bird.) 



Species: Microtriccus semijlavus (Sclater and Salvin), Microtriccus semi- 

 flavus brunneicapillus (Lawrence). 



Hylonax gen. nov. {Cotingidse.) 



Supei'ficially resembling the more stoutly built species of the Tyrannine 

 genus Myinrchus Cabanis, but tarsal envelope non-exaspideau (the planta 

 tarsi consisting of a single continuous row of rather large, quadrate scutella, 

 separated from the inner edge of the acrotarsium by a narrow nonscutellate 

 space), bill longer (as long as head), narrower, with straighter culmen and 

 tip of maxilla more abruptly decurved and more strongly uncinate, and 

 with gonys more convex, more ascending terminally, more prominent 

 basally. 



Type, Myiarchus validus Cabanis = Hylonax validus. 



("TXr;, forest ; &va^, king.)
