loiifjor tliaii hroiul, itipcriiii; vory jiraduMlly and nitlicr ivii'iihivly, but to ii loss dei;ree 

 near the iipcx, to a bluntly pointed tip, which is scarcely tnrnod downward. 



Fore winits (39 : Hi) about two-thirds as lonj; again as broad, the costal marajin very 

 slightly and regularly bowed, scarcely more so at the base, tlie outer angle abrupt but 

 rounded otf. the outer border curved a little at either end, nearly straight in tlie mid- 

 dle half, perhaps a little fidler in the J* , its general direction at an angle of about (!.5° 

 with the costal margin, the inner margin straight, the outer angle well rounded off. 

 Costal norvure terminating a little l)efore the tip of the cell; subcostal with three 

 superior branches, the tlrst arising at about tlireo-fifths the distance from the l)!ise 

 to the apex of the cell; the second at about one-fonrth way from there to the apex 

 of the cell; the third at some distance before the apex of the cell and opposite the 

 base of the second median nervure, forking beyond its middle; the cross veins closing 

 the cell are bent at a considerable angle and are very faint excepting immediately 

 next the main norvures. Cell half as louir as the wing and about three and a half 

 times longer than bro.ad. 



Hind wings with the costal margin gently convex at the base, beyond straight, the 

 outer border pretty strongly rounded, rather fuller above than below and in the $ 

 than in the ?, the inner border a little convex, the outer angle very broad. Sub- 

 raeilian nervure terminating at the anal angle ; internal nervure terminating a little 

 beyond the middle of the inner border. 



Androconia sli;;htly fan-shaped , the lamina expanding a little from the base, the .stem 

 nearly half as long as the lamina. 



Fore tibiae a little more than three-rtfths the length of the hind tibiae; the fore legs 

 either of the same structure as the others ( ?) ; or the claws are subconnate, nearly 

 straight and overlap at tip, and the paronychia are wanting {$); excepting in 

 diminished size they difl'er little from the other legs, but the tibial spur is naked 

 and no longer than an ordinary spine, the tarsal spines are less frequent .and confined 

 to two rows, the space between them scaled. Middle tibiae nearly five-sixths the length 

 of the hind tibiae, provided at tip with nather short slender spines, mostly concealed 

 by scales. First joint of tarsi a little longer than the three succeeding combined ; the 

 second as long as the third and fourth together or as the fifth alone; the fourth 

 scarcely half so long as the second ; joints furnished beneath with a triple row of 

 slender spines, the apical spines of each joint longer; claws small, I'.ather strong, con- 

 siderably curved, tapering, finely pointed; paronychia bifid, the superior lobe nearly 

 as long as the claw, curved a little in the same direction as it, tapering a little ; in- 

 ferior lobe tapering considerably, rather long, curved strongly inward so as to be 

 generally concealed from view ; pulvillus wanting. 



Upper organ of m.ale abdominal appendages small but stout, gibbous, the lateral 

 portions bearing each a posterior appressed lobe, provided at its posterior inner edge 

 with an inward directed, delicate, slightly curving thorn, as long as the breadth of the 

 lobe; clasps bulbous, or almost globular at base, emitting at tip a slender needle bent 

 at base, so as to be directed inward and backward, crossing that of the opposite side. 



Egg. Very depressed echinoid shaped, the whole upper surface hollowed and in- 

 creasingly so toward the centre; covered with not very prominent tubercles, connected 

 by fine raised lines ; between every set of three, four or five of these a sligliter promi- 

 nence, connected by similar lines to the higher ones. 



Caterpillar at birth. Head : ocelli four in number, arranged around a circular 

 black spot, the posterior one largest, the other three about equal, two of them situated 

 at equal distances along the upper border, the fourth below, nearly as far from the 

 largest as the front upper one is. Body subcylindrical, tapering, flattened beneath 

 and a little above, but still as high as broad, the sides well rounded though subtecti- 

 form. and the lower margin produced laterally a little. First thoracic segment bear- 

 ing above in the middle a slightly raised, large shield, the sides of which converge 

 strongly anteriorly, making the anterior border very short, while the posterior is long 

 and well rounded. It bears three arcuate rows of warts, emitting long, forward and 

 upward directed hairs, the anterior row consisting of three, the middle of five, and
