I'oro wins (42 : 14) two and a half times longer than broad, the lower outer niiirle 

 fallln;; scarcely outside the middle .>f the costal margin; costal margin straight with 

 the slightest possible detlectlon at cither extremity ; outer margin gently convex with a 

 scarcely perceptible bend In the upper median area; Inner margin straight. Costal 

 nervure extending nearly to the apex of the cell ; subcostal very closely approximate 

 to the costal margin, the second nervule arising In the middle of the wing; cell two- 

 thirds as long as the wing, excessively slender, subcc|ual In the apical two-thirds; llrst 

 median nervule arising midway between the base of Hie wing and tlie origin of the 

 second nervule, far before tlie base of the llrst subcostal nervule; the second opposite 

 the second subcostal nervule; just beyond Its origin a short, recurrent nervule Is seen; 

 internal norvure straight, pretty short. 



Hind wing a little longer than broad, the basal lobe large; costal margin beyond 

 straight ; outer margin between the costal nervure and lower median nervule regularly 

 and strongly convex ; below this, where the wing is unusually broad, there Is a distinct 

 full, rounded lobe, with the submedian nervure at its fullest point ; anal angle well 

 rounded. 



Legs, 2, 3, 1. Femora furnished beneath with a fringe of hairs, decreasing in lensth 

 toward the tip ; they are very long on the hind legs, moderately long on the middle 

 legs, and very sliort on the fore legs; hind tibiae furnished above with an abundant 

 fringe of long, but partially recumbent hairs upon the outer side. Femora 2, 1,3; 

 tibiae 2, 3, 1; tarsi 3,2, 1. Fore femora perceptibly longer than the hind, and about 

 three-fourths the length of the middle femora. Fore tibiae scarcely two-thirds the 

 length of the fore femora, and about three-tlfths the length of the middle tibiae, which 

 are but little longer than the hinder pair. Leaf-like appendage of fore tibiae rather 

 small, attached to the middle of the outer two-thirds of the joint, nearly equal as far 

 as the extremity of the joint, where it tapers to a point and is bent very strongly down- 

 ward, the whole not far from Hve times as long as l)road ; othertibiae armed at the tip 

 with a pair of exceedingly long and slender unecjual spurs, and the hind tibiae with a 

 similar secondary pair in the middle of the apical two-thirds of the joint; the two 

 hinder tibiae are als o pro vided exteriorly with a lateral row of distant recumbent spines. 

 Tarsal joints 1,2,3,4,5; fore tarsi three-fourths the length of the middle, three-tlftbs 

 the length of the hind tarsi, all furnished beneath with a triple row of rather short 

 spines, those at the extremity of the joints scarcely, if at all, longer than the others; 

 basal joint fully as long as the others taken togetlier; second only two-tlfthsaslongas 

 the basal joint, or even slightly less than this on the fore legs. Claws small, com- 

 pressed, curved strongly and regularly, tapering to a point. Pad large, bulbous. 

 Paronychia bilobed, the upper lobe laminate, broadly falcate, as long as the claw ; lower 

 lobe thread like, cqu.il, half as long as the claw. 



Abdominal appendages : Upper organ small but stout, strongly convex transversely > 

 narrow and well arched, the simple hook curving downward, provided with a median 

 ridge above ; lateral arms connate, forming a triangular piece somewhat similar to and 

 lying beneath the hook. Clasps broad, flat, equal, laminate, about twice as long as 

 broad, as long as the upper organ, the upper posterior angle slightly produced as a 

 tooth 



Egg. Almost exactly hemispherical, a little more than half as high as broad; basal 

 breadth retained for about one-tenth its height, beyond which it is domed with the 

 greatest regularity, there being not the least appearance of flatness on the summit, 

 though in the centre the micropyle is slightly depressed; surface covered with a retic- 

 ulation of very regular cells, the floor of which is profusely punctate. 



Caterpillar at birth. Head large, narrowed and subtuberculate above with very dis- 

 tant, short, tapering bristles, the median suture deeply impressed. Body exceed- 

 ingly long, slender, e(iual ; dorsal thoracic shield rather broad, uniform ; bristles very 

 short and slight, hardly one-tenth the length of the segments, scarcely tapering, 

 rounded at tip, and with a scarcely perceptible enlargement, arranged as follows : a
