LEPIDOPTERA HETEROCERA. 879 



antici breves, femoribus dilatatis, tibiis dense fasciculatis ; 

 alee tinea exteriore obscure fusca obliqna denticulata, linea sub- 

 marginali cinerea denticulata informi ; anticce acutce, costa 

 interiore contracta, linea interiore obscure fusca obliqua, reni- 

 formiflava. 



Male. Cinereous-brown, slender, cinereous beneath. Palpi 

 slightly ascending, not long, densely tufted above, thereby appearing 

 capitate. Antennae pubescent. Abdomen not extending beyond 

 the hind wings. Legs moderately stout ; femora slightly fringed. 

 Fore legs short ; femora much dilated ; tibiae densely tufted. Wings 

 moderately broad ; exterior line dark brown, oblique, denticulated ; 

 submarginal line cinereous, denticulated, irregular ; marginal marks 

 dark brown, hardly lunulate. Fore wings acute ; costa somewhat 

 contracted between the base and the exterior line ; interior line dark

Genus ILYEGTS. 



Mas. Corpus vix robustum. Fasciculus frontalis planus, 

 magnus. Proboscis distincta. Palpi ascendentes, corapressi, sub- 

 nmbriati ; articulus 2us subarcuatus ; 3us subfusiformis, parvus. 

 Antennae breviusculae, sat late pectinatae. Abdomen alas posticas 

 perparum superans. Pedes glabri ; calcaria longissima. Alae 

 latae, breviusculae ; anticae subfalcatae, margine exteriore subcon- 

 vexo. 



Male. Body hardly stout. Frontal tuft flat, large. Proboscis 

 moderately long. Palpi aseending, compressed, slightly fringed, 

 rising higher than the vertex ; second joint slightly curved, mode- 

 rately broad ; third somewhat fusiform, about one-fourth of the 

 length of the second. Antennae rather short, rather broadly pecti- 

 nated. Abdomen extending very little beyond the hind wings. 

 Legs smooth, moderately stout ; spurs very long. Wings broad, 

 rather short. Fore wings slightly subfalcate ; exterior border mode- 

 rately oblique, slightly convex in the middle. 



This genus differs much in structure from all the other genera 

 of Herminidce, and perhaps should be excluded from the family.
