" Head rather broad, hairy. 
" Eyes nearly round, smooth. 
" Palj'i porrect, sbghtly ascending, divergent, projecting considerably beyond tlie head; the 
lirst and second joints clothed with scales and long setiform divergent hairs ; the third 
joint with scales, and more or less approssed hairs. First joint subcybndric, curved, about 
one fourth the length of the second ; second joint slightly curved, much swollen beyond the 
middle, then narrowed towards the apex, which is truncate ; third joint very small, 
acicular, about one fourth the length of the second. 
" Antcniut rather short, terminating in an abrupt pyriform club. 
" Thokax rather stout, rounded, oval ; aldomen moderate, about two thirds the length of the inner 
margin of the wing. 
" Fore whig trigonate ; the costal margin rounded ; the outer about two thirds the length of the 
costa, sometimes slightly concave, sometimes nearly straight, often rounded ; inner about 
equal in length to the outer margin, nearly straight. Costal nervure stout, extending 
about three fifths of the length of the wing ; subcostal slender, sometimes emitting its first 
and second nervules near together before the end of the cell, the third at less than half the 
distance between this and the apex, the fourth rather more remote from the apex than 
from the third ; sometimes emitting its first nervule before the end of the cell, its second 
at about an equal distance from the first and third, its fourth nearer to the third than to 
the apex. Upper discocellular nervule very short, sometimes almost wanting ; middle 
curved upwards, longer than the lower, which is nearly straight, and anastomoses with the 
third median nervule at some distance from its origin. 
" Hind iving obovate ; the margins about equal, all rounded. Proecostal nervure simple, slightly 
curved, directed oiitwards ; discoidal nervule appearing to be a third subcostal nervule. 
Discoidal cell closed by a slender discocellular, sometimes flexuous, sometimes nearly 
straight. 
Fore legs of the male fringed with long delicate hairs; tibia smooth, rather shorter than the 
femur ; tarsus shorter than the tibia, one-jointed, subcylindric, tapering towards the apex. 
Of the female scaly, slightly fringed with hairs; tibia fully as long as the femur, smooth, 
slenderest in the middle ; tarsus shorter than the tibia, smooth, five-jointed ; the first 
joint twice the length of the rest combined ; the second barely one fourth the length of the 
first : the third one half the length of the second ; the fourth transverse, three fourths the 
length of the third : these joints all armed at the apex with a short spine on each side, 
not covered at the base by any bunch of hairs or setae situated on the next joint ; fifth 
joint smaller than the fourth, transverse, unarmed. 
" Middle and hind legs with the femora and tibise of about equal length, the latter spined all 
round ; the lateral spines much the longest ; the spurs very distinct. Tarsi about as long 
as the tibiae; all the joints nearly eylindric, spiny all round ; first joint neai-ly equal to the 
others combined ; the spines below arranged in two alternating series ; second, third, and
