EcESELiODES, gen. nov. 



Fore wings narrow, elongate ; costa straight ; hind margin 

 obliquely curved ; apex blunt ; labial palpi (female) erect, 

 the second joint with long erect hairs, partially hiding the 

 terminal joint, which is aciculate and rises above the vertex ; 

 tongue and ocelli present ; maxillary palpi invisible ; antennae 

 in female annulated, filiform, in male coarsely pectinated, 

 enlarged at the base, which also bears a dense erect tuft ; 

 near the base of the submedian between it and the interno- 

 median is a bladdery protuberance, and the underside of the 

 fore wing is beset with hairs ; cell long, the end wedge- 

 shaped ; first median nervule from the angle at the base of 

 the wedge; second, third, and lower radial from the point; 

 between the median and submedian is a strongly developed 

 independent surplus vein, which near the base stands out as 

 prominently as a true vein, as in Castnia j this vein reappears 

 in the hind wing.
