wing. Beneath the third streak are two dark-fuscous spots, 

 sometimes margined with pale ochreous. At the tip are three 

 dark-fuscous dots, one nearly on the extreme apex and two 

 others behind it. Cilia of the tip somewhat dusted with fus- 

 cous, the inner margin ochreous. Hind-wings rather dark 

 ochreous, cilia the same. 



TRICHOTAPHE. 



Fore-wings scarcely pointed, hind margin oblique, costa 

 behind the tip deflexed. The discoidal cell is closed and 

 rounded behind. The subcostal nervure sends four veins to 

 the costa behind the tip, the last of which is furcate, and one 

 to the hind margin beneath the tip from the cell. The 

 median sends four branches to the hind margin, the last of 

 which is furcate. Hind-wings emarginate in the middle of 

 the costa and somewhat emarginate beneath the tip, with an 

 intercostal cell at the base ; subcostal bifid from the discal 

 nervure, which sends a branch to the hind margin. The 

 median is three-branched. 



Head smooth, with appressed scales. Without ocelli. 

 Eyes round and moderately prominent. Labial palpi re- 

 curved ; middle joint slightly curved, rather broad, compressed 

 laterally, squamose on the sides and hairy toward the end ; 

 terminal joint slender, smooth, pointed and not so long as the 

 middle joint. Maxillary palpi short and distinct. Antennas 

 rather more than one-half as long as the fore-wings, somewhat 

 denticulated and microscopically pubescent beneath in the 

 male ? Tongue scaled at the base, nearly as long as the 

 thorax beneath. 



Middle joint of labial palpi much flattened ; hairy above 

 and below, with diverging hairs. 



T. setosella. Head, face and thorax rather dark ochreous. 

 Labial palpi, middle joint blackish-brown externally, with the 

 spreading hairs above and beneath at the end, ochreous; 

 terminal joint ochreous, tipped with fuscous. Antennas 

 fuscous, ochreous toward the base. Fore-wings dark brown,
