cell, a row of blackish dots in the disc, limiting the outer marginal space, often more 
or less obsolescent, and two biackish-brown sub-apical dots on the costa. Hinclwing 
entirely covered with greyish-green irrorations, 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. Hindwing 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, antennse, 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-diseal spots black, the latter decreasing in size 
upwards. Hindwing green, a small round silvery white spot at the end of the cell, the
