ho fore the iipex of tlie cell, fork in;; iiiiihviiy between the huso of the nervuleaml the eiul 

 of its upper hriiuch; cross veins transverse, obsolete, scarcely perceptible even next 

 tlie main veins; cell half ns long as the wing anil nearly four times as long as broad. 



Hind wings consiilerably anil roundly expanded next tlic base, beyond, fully lialf way 

 to the tip, scarcely convex, then curving downwards rather rapidly and somewhat 

 abruptly ( <f). or roundly ami not to so great an extiint ( J ) ; outer liorder l>roadly 

 rounded, very sliglitly produced and angulated at tlie lower mciliau nervule, sliglitly 

 and roundly cmarginate iu tlie inedio-snbniediau interspace; inner margin broadly ex- 

 panded at the base, beyond scarcely convex, sliglitly bont just l)efore the straight 

 apex, the angle abrupt and scarcely rounded. Snlnncdian nervure terminating on the 

 outer border, just beyond the anal angle; internal nervure terminating considerably 

 beyond the middle of the inner margin. 



Fore tibiae live-sixths the lengtli of the liind tibiae ( ? ), or scarcely shorter than they 

 ( (J ), the spurs naked ; fore tarsi fully as long as ( $ ) or a little shorter than ( g ) the 

 tibiae; tlie last tarsal joint either similar to the same part in the other legs ( ? ) ; or 

 small, tapering, armed with only a stout, apical, tapering spine, whicli ditters from the 

 other spines of the under surface which crowd up to it only iu size, and furnished 

 above with very short and dense hairs instead of scales {$). All the femora provided 

 with a fringe of rather close, long liairs on the under surface. Mitldle tibiae as long 

 ns {$) or a little shorter than (?) tlic hind tibiae; armed beneath with rather short 

 and slender, scattered spines and apically with a pair of rather long and stout spurs, 

 only the tip bare. First joint of middle and hind tarsi rather strongly gibbous in the 

 male: in the female of the usual appearance, considerably more than eijualling in 

 length all the other joints combined; second, third and fifth joints about eipial, the 

 fourtli smallest: joints armed beneath rather profusely witli ratlier long and slender, 

 scattered spines, mostly collected in crowded rows at the sides, an apical pair on each 

 joint a little longer than the others, the under surface devoid of scales, excepting on 

 the first joint; claws small, compressed, not stont, tapering, finely pointed, falcate, 

 but not very strongly curved ; paronychia double, the superior lobe as broad at base 

 as the claw, nearly straight, considerably exceeding the claw in length, the tip en- 

 large<l and very broadly rounded, almost docked; inferior lobe moderately slender, 

 equal, the tip pointed, about as long as the claw and curving considerably both toward 

 the claw and inward ; pulvillus inconspicuous. 



Male abilominal appeudases with tlie lateral fiaps of the upper organ forming bent and 

 equal cylinders, the proximal halves parallel and enclosing lietween them a deep and eiiual 

 mesial cleft, the distal halves bent downward and outward; lateral arms strongly arcu" 

 ate but not bent ; clasps coarse, stout, bullate. several times longer than broad, well 

 rounded. 



Egg. Demi-echinoid in shape, the base being very broadly docked, flat, not curved 

 at the edge, from which it is very broadly arched, not high; the cells are very large 

 and conspicuous, bounded by heavy, elevated walls, are irregular in outline, but dis- 

 posed in obscure, irregular, horizontal and oblique rows ; the cells are smallest at the 

 base, increase in size upwardly, largest on the upper portion of the sides and decrease 

 again at and around the summit. Micropyle rosette lying on the floor of an infundi- 

 buliform cavity and composed of minute cells, bounded by low, heavy walls. 



Caterpillar at birth. Head broadest at summit, the sides as far as the bottom of 

 the ocellar field tapering a little, scarcely convex; below tapering rapidly, the lower 

 surface broadly rounded, crown of hemispheres broadly rounded, rather deeply and 

 broadly cleft between them. Body largest at anterior extremity, tapering a little on 

 the thorax both as seen from above and from side, very slightly on the abdomen ; pos- 

 teriorly Well rounded, above a little depressed, below greatly flattened, much as in 

 the mature forms of the family. First thoracic segment furnished with a transverse, 

 double row of very long hairs curving strongly forward over the head ; remaining seg- 

 ments furnished as follows : flrst, a subdorsal row of hairs seated on higli and slender 

 papillae, two on each segment, one central and exceedingly long, curving backward, 

 and. when viewed posteriorly, curving first outward and upward and then upward and
