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 ILYBGIS. 
Mas. Corpus vix robustum. Fasciculus frontalis planus, 
magnus. Proboscis distincta. Palpi ascendentes, compressi, sub- 
fimbriati ; articulus 2us subarcuatus ; 3us subfusiformis, parvus. 
Antennas breviusculae, sat late pectinatae. Abdomen alas posticas 
perparum superans. Pedes glabri ; calcaria longissima. Alae 
lat®, 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.
