OF EXTRA-ETJROPEAK THICHOPTEBA, 117 



gine costali intus fimbriato, margine apicali fimbriis longis in- 

 structo ; cellula discoidali occhisa, venis irregularibus (6)- 



Head very small : eyes small and round : first joint of the antennas 

 extraordinardy long, equal to, or exceeding, the length of the whole 

 body, standing out straight from the head, strong, compressed, but 

 irregular in its breadth, arising from a j)rominencc on the head, fur- 

 nished internally at the base with a strong curved spine, which is 

 widened and truncate at the apex, the basal portion clothed with 

 stout hairs, afterwards fringed with two rows of very long slender 

 hairs ; the rest of the antennae not exceeding the length of this first 

 joint, articulated to it almost at a right angle, strongly curved, com- 

 posed of numerous short and slender joints : maxillary palpi appa- 

 rently 2-jointcd (or there is perhaps a short, but invisible, basal 

 joint), long, extending far beyond the head ; first joint long, porrect, 

 band-like, almost geniculate at the base, afterwards bent, strongly 

 plumose and scaly ; second joint equalling the first in length, but 

 slender and curved : labial palpi very slender ; first joint very short, 

 scarcely visible ; second joint long, cylindrical, straight ; third joint 

 equal to the second, curved. Thorax small. Legs slender, spurs 

 2, 4, 4, moderately long and subequal, hairy, those on the anterior 

 tibirc less equal and more hairy than the others ; tarsal joints long 

 and slender. Abdomen short ; inferior appendices long. 



Anterior wings oval, scarcely dilated, the upper half thinly clothed 

 with scales intermingled with hairs, the lower half with hairs only : 

 these two divisions are separated by a dee)), narrow, longitudinal 

 groove, extending from near the base almost to the apex, containing 

 more closely placed scales ; the groove is placed between the ramus 

 thyrifcr (which it nearly obliterates) and the ramus clavalis, this latter 

 being very strong and furnished with an updirected fringe of long 

 scale-like hairs, which form a cover over the groove ; subcosta and 

 radius straight and subparallel ; discoidal cell short, narrow, closed ; 

 no apparent cellula tbyridii ; the neuration in the lower half of the wing 

 (below the groove) irregular, forming five large irregular cells : costal 

 margin with a long inturned fringe in its basal half; apical margin 

 with very long fringe. Posterior wings short, scarcely so broad in 

 their widest part (which is beyond the middle) as the anterior, the 

 apex elliptical ; hairy and with a few scales on the costal margin ; 

 fringes very long : neuration regular ; subcosta and radius confluent 

 for the greater part of their length, afterwards separating and di- 

 vergent, forming a long apical fork ; discoidal cell very similar to that 

 in the anterior wings, closed : lower branch of ramus discoidalis 

 simple ; ramus subdiscoidalis simply forked, connected with the ramus 

 discoidalis by an oblique veinlet beneath the discoidal cell. 



Like the last genus, allied to Mormonia, or perhaps more nearly
