cell, a row of blackish dots in the disc, limiting the outer marginal space, often more 

 or less obsolescent, and two blackish-brown sub-apical dots on the costa. Hindwiny 

 entirely covered with greyish-green ii-rorations, a large vermilion patch at the end of 

 the cell with two outwardly extended teeth, its inner portion containing a round white 

 spot, a discal row of small red-brown spots. 



Female. Upperside. Forewing paler and brighter than the male, the basal 

 irrorations more extensive, the cell spot and outer band about the same size, but the 

 latter contains a row of pale spots, the middle one the smallest. Rindmng covered 

 with grey irrorations, a large vermilion patch at the end of the cell, sometimes with 

 one, sometimes with two external teeth, a costal and outer marginal blackish band, 

 broader than in the male, but its interior margin is very diffuse and obscure and 

 contains a row of large pale spots ; cilia of both wings as in the male. Underside as in 

 the male. Palpi above, antennae, and collar crimson, body above greenish-grey, below

Imago. — Male. Upperside rich bright sulphur-yellow. Forewing with the base 

 thickly irrorated with black atoms, costal margin slightly irrorated, a black oval spot at 

 end of cell, outer marginal black band broad, its inner edge irregular and somewhat 

 sinuous, a row of more or less elongate spots of the ground colour down its centre, each 

 being connected with the margin by a pale, slender line, the spots in the middle more or 

 less obsolete. Ilindwing irrorated with greenish-black, except for a broad pale band of 

 the ground colour, its inner edge with a succession of blackish curves in the interspaces, 

 which thicken upwards into a black sub-apical patch, outer edge with a very obscure 

 sub-terminal band, which darkens upwards and is deep black at the apex ; a large 

 yellow spot at the end of the cell centred with orange ; cilia yellow, of the hindwing 

 posteriorly it is pink. Underside. Forewing yellow, the costal and outer margins 

 green, discocellular spot and three post-discal spots black, the latter decreasing in size 

 upwards. Hindwing green, a small round silvery white spot at the end of the cell, the
