so long as the thorax. Labial palpi short, the first and second joints 

 densely scaly, the scales hair-like, the third joint clothed with short 

 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. Antennae 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 discoidal 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 tibiae densely hairy. The 

 anterior tibiae with a broad spur, nearly as long as the tibia itself, 

 composed of a flat, slightly curved lancet-shaped lamina, fringed an- 

 teriorly. Tibiae 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-
