scales : first joint much curved, broadest at the apex; second joint 
one-half longer than the first, subcylindric, stoutest in the middle, 
truncate at the apex; third joint small, oval, about one-third the 
length of the second joint. Antennz of the male elongate, densely 
bipectinate, each pectination beautifully fringed with hairs: of the 
female long, setaceous, the inside set with short stiff hairs. 
Thorax stout, crested, the crest much highest in front. Anterior 
wings elongate, the anterior margin but little curved until near the 
apex ; outer margin rather more than half the length of the anterior, 
slightly dentate; inner margin nearly straight, rather longer than 
the outer. Costal nervure extending about three-fourths the length 
of the costa. First subcostal nervule thrown off beyond the middle 
of the cell, terminating not far from the extremity of the costal ner- 
vure; second subcostal nervure thrown off shortly before the end of 
the cell, curved so as to cross the subcostal nervure at some distance 
beyond the end of the cell, terminating on the outer margin midway 
between the fifth subcostal and the first discoida] nervule; third 
subcostal nervule arising rather nearer to the end of the cell than to 
the apex of the wing ; the fourth nearer to the third than to the apex, 
this nervule terminating at the apex. First discoidal nervule appear- 
ing at first sight to be a continuation of the subcostal] nervure, the, 
upper disco-cellular nervule being wanting. Lower about the same 
length as the middle disco-cellular nervule, united to the third me- 
dian nervule shortly after its origin. Posterior wings with the ante- 
rior margin nearly straight, longer than the outer, which is rounded. 
Inner margin about two-thirds the length of the outer. Cell closed. 
Upper and lower disco-cellular nervule of about equal length. Dis- 
coidal nervure very slender ; the basal portion, as far as the end of the 
cell, atrophied. Legs with the femora and tibie densely hairy. The 
anterior tibie with a broad spur, nearly as long as the tibia itself, 
composed of a flat, slightly curved lancet-shaped lamina, fringed an- 
teriorly. Tibiz of the middle pair with two unequal spines at the 
apex, those of the third pair with two before the apex, two at the 
apex. Tarsi scaly, the first joint much the longest; claws small, 
curved ; paronychia broad, very hairy, especially at the apex, shorter 
than the claw; pulvillus jointed, the second joint very broad. Ab- 
domen clothed with long hairs, elongate, longer in the male than in 
the female. 
Larva stout, tapering towards the tail, the back flat, with a cre- 
nated ridge on each side.

I have not thought it necessary to enter into a detailed specific 
character of this insect, as the accompanying figure will give a far 
better idea of the species than the longest description. The noc-
