828 BRITISH BUTTERFLIES. 



scarcely perceptible even next the main veins ; cell half as long as the wing and 

 nearly four times as long as broad. Hindwings considerably and roundly expanded 

 next the base, beyond, fully half-way to the tip, scarcely convex, then curving 

 downwards rather rapidly and somewhat abruptly ( 3 ), or roundly and not to so 

 great an extent ( ? ) ; outer border broadly rounded, very slightly produced and 

 angulated at the lower median nervule, slightly and roundly emarginate in the 

 mediosubmedian interspace ; inner margin broadly expanded at the base, beyond 

 scarcely convex, slightly bent just before the straight apex, the angle abrupt and 

 scarcely rounded. Submedian nervure terminating on the outer border, just 

 beyond the anal angle ; internal nervure terminating considerably beyond the 

 middle of the inner margin. Legs : Fore tibiae five-sixths the length of the hind tibiffl 

 ( ? ), or scarcely shorter than they ( <? ); the spurs naked ; fore tarsi fully as long 

 as (?) or a little shorter than ( <? ) the tibiae ; the last tarsal joint either similar to 

 the same part in the other legs ( ? ), or small, tapering, armed with' only a stout, 

 apical, tapering spine, which differs from the other spines of the under surface 

 which crowd up to it only in size, and furnished above with very short and dense 

 hairs instead of scales ( J ). All the femora provided with a fringe of rather close, 

 long hair on the under surface. Middle tibiae as long as ( d" ) or a little shorter 

 than ( ? ) the 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 equalling in length all the 

 other joints combined ; second, third, and fifth joints about equal, the fourth 

 smallest ; joints armed beneath rather profusely with rather 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 stout, 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 enlarged 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. 



Genitalia. — Male, abdominal appendages with the lateral flaps of the upper 

 organ forming bent and equal cylinders, the proximal halves parallel and enclosing 

 between them a deep and equal mesial cleft, the distal halves bent downward and 

 outward ; lateral arms strongly arcuate, but not bent; clasps coarse, stout, bullate, 

 several times longer than broad, well rounded. 



Ovum. — 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 disposed 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 infundibuliform cavity, and composed of minute cells, bounded 

 by low, heavy walls. 



Larva (newly-hatched). — 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; posterior 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 segments furnished as follows : first, a subdorsal row of 

 hairs seated on high and slender papilla', two on each segment, one central and 

 exceedingly long, curving backward, and, when viewed posteriorly, curving first 

 outward and upward and then upward and inward, tapering very slowly to a tine 

 point, anteriorly very minutely spiculiferous, the other posterior and a little outside 

 the former, not very long, nearly straight but turned backward, tapering, slender, 

 finely pointed, apparently smooth ; second, a ventrostigmatal row of hairs seated 

 upon rather high papilla 1 , three on a segment, long and slender, quite straight, 

 turned a little backward, very minutely spiculiferous on both sides, finely pointed; 

 third, a laterostigmatal series of large, circular, crateriform papillae or annuli, one 

 in the centre of the 1st to 6th abdominal segments, and a similar papilla on 

 the 7th segment in place of the smaller and outer subdorsal hair ; fourth.
