it ; discocellulars in a straight outwardly oblique line ; vein 5 not visible ; 3 emitted

 length of the costa of forewing, club gradual, slender, rather long, tip acuminate, 

 slightly curved over ; palpi with the second joint densely clothed, third minute, thick 

 and somewhat blunt ; hind tibise fringed with two pairs of spurs, the upper pair small,

Imago. — Male. Upperside rich vinous-brown, no markings. Forewing with the 

 cilia brown. Hiiidwing with the cilia brown to the end of vein 2, from thence to the 

 anal angle it is bright orange, the cilia increasing in length hindw^ards, the orange 

 colour extending upwards a little inside the margin, leaving a short tooth-like brown 

 mark at the end of vein 1. Underside with the ground colour as on the upperside, but 

 slightly paler. Foreicivg with the hinder margin })roadly ochreous-grey up to the first 

 median nervure, but hardly reaching the outer margin ; all the veins bronzy-green, 

 except on the basal two-thirds of the lower margin of the cell, vein 2 and the sub- 

 median vein. Hindwing with all the veins similarly streaked, but darker green and 

 more prominent ; the orange cilia at the anal angle as on the upperside. Antennae 

 black, grey beneath ; palpi, head and body above concolorous with the wings ; on the 

 underside the palpi are orange, pectus dull greyish -orange, thorax brown with some 

 dull orange marks, abdomen grey tinged with orange, with blackish bands. 



Expanse of wings, $ 2 inches. 



Female unknown to us ; de Niceville says : " In Colonel Lang's collection is a very 

 old specimen from Sikkim, without head or abdomen, which we believe to be the 

 female of this species. On the upperside of both wings it is obscurely glossed with 

 green on the basal two-thirds, the forewing is rather broader, the outer margin slightly 

 convex : and on the hindwins the orange colour at the anal angle is rather broader 

 (not nearly so broad as in P. ismene or P. Ityela), and the cilia are throughout orange. 

 Underside paler than in the male, the ground-colour obscure green rather than brown,
