380 BRITISH BUTTERFLIES. 



middle of the hind border, abruptly elevated behind the antennas, forming a 

 transverse ridge for their support ; separated from the occiput by a rather deep, 

 slightly curving groove, its middle curving forward, the sides forming a right 

 angle with each other, the anterior slope of the groove the more abrupt. Eyes not 

 very large, moderately full, delicately and distantly pilose on the lower two-thirds 

 with very short hairs, increasing in length downward. Antennas inserted in the 

 middle of the summit, separated by a space equal to the width of the antennal pits, 

 slightly longer than the abdomen, composed of about 34 joints, of which the last 

 twelve or thirteen form a club similar in all respects to that of Everes, excepting 

 that the tip is more broadly rounded. Palpi slender, scarcely more than half as 

 long again as the eye, the apical joint very nearly half as long as the 'penultimate, 

 the whole under surface, and particularly that of the basal and middle joints, 

 furnished with a mass of long, erect, delicate hairs, as long as the apical joint, 

 which becomes shorter apically, and which lie in a vertical plane, but not 

 compressed. Patagia small, slender, nearly flat, scarcely arched longitudinally, 

 two or three times longer than broad, tapering very gradually and rather regularly, 

 but to a less degree near the apex, to a bluntly-pointed tip, which is scarcely 

 turned downward. Forewing about two thirds as long again as broad, the cotsal 

 margin very slightly and regularly bowed, scarcely more so at the base, the outer 

 angle abrupt but rounded off, the outer border curved a little at either end, nearly 

 straight in the middle half, perhaps a little fuller in the <? , its general direction at 

 an angle of about 65° with the costal margin, the inner margin straight, the outer 

 angle well rounded off. Costal nervure terminating a little before the tip of the 

 cell; subcostal with three superior branches, the first arising at about three-fifths 

 the distance from the base to the apex of the cell ; the second at about one- fourth 

 way from these 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 nervures. Cell half as long as 

 the wing, and about three and a half times longer than broad. Hindwings 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 s than in the 

 2 , the inner border a little convex, the outer angle very broad. Submedian 

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

 the middle of the inner border. Androconia slightly 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-fifths the length of the hind tibiss ; the forelegs 

 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 differ 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 tibial, provided at tip with rather 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, rather strong, considerably 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 ; inferior lobe tapering considerably, rather 

 long, curved strongly inwards so as to be generally concealed from view ; pulvillus 

 wanting. 



Genitalia : Upper organ of male 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, \he whole upper surface hollowed, and 

 increasingly 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 

 slighter prominence, connected by similar lines to the higher ones. 



Larva (newly-hatched). — Head : Ocelli four* in number, arranged round a 



* Six, see our plate, depicting first skin, where they are seen to be arranged 

 in the usual manner, viz., five as a lunule, and one away centrally.
