3o8 LEPID OP TE RA . 



ilattened and throwing back a point toward the base of the 

 wing, but very indistinct and only visible by its slender 

 orange-red margin ; reniform stigma also large and similarly 

 indicated, but containing at its base a purple-brown spot; 

 between them is sometimes a slender cloudy orange-red or 

 purplish central shade angulated as in the first line, but often 

 nearly obliterated ; cilia ochreous-yellow. Hind wings mode- 

 rately broad and ample, the hind margin rather sinuous ; 

 shining pale straw-colour or yellowish- white, without mark- 

 ings ; cilia similar. Female hardly differing in any respect 

 except that the abdomen, which is but little stouter, tapers 

 off behind to a long sharp conical sheath, from which the 

 ovipositor often protrudes. 



Underside of all the wings pale straw-colour or pale 

 yellow, with all the nervures deeper yellow, and the costa 

 tinged with orange-red. Body and legs pale yellow. 



Principally variable in the distinctness of the markings, 

 which usually are faint and often partially obliterated or 

 even very nearly totally so. In occasional specimens the 

 costa toward the apex is tinged with smoky colour which 

 more rarely extends to the hind marginal cilia. There is 

 a record of one or two specimens, taken near London, in 

 which the ground-colour is a warm buff or yellow-brown, 

 irrorated with fuscous scales, the stigmata orange-coloured ; 

 the central shade fuscous and broken into blotches, and the 

 hind wings banded with fuscous towards the hind margin. 

 One of these, the most strikingly marked, was taken by 

 Mr. Henry Bartlett at Highgate in 1870, the other by the 

 late Mr. Stainton at Lewisham in 1846. 



On the wing in August and September. 



Larva about an inch and a half in length and of moderate 

 proportionate bulk ; head very slightly narrower than the 

 second segment, the lobes round ,and polished, pale yellow, 

 the jaws black, and just above on each side a small red 

 spot ; body cylindrical and of nearly uniform width
