LYCAENIDAE 
bark or leaves, they can find. Before finally settling down to 
pupate, they crawl restlessly about if they find no hiding place ; 
therefore, some may reach the ground and there spin up. The 
larval stage lasts about forty-five days. 
Pupa. The pupa is stoutly proportioned and 10*20 mm. 
in length ; the thorax is rounded and swollen ; the abdomen 
is also bulging and curves abruptly to the anal segment, which 
is without cremastral hooks. The ventral surface is rather 
flat ; the head is rounded. Except for the wings, the surface 
is densely covered with extremely short and minute spines, 
and the entire surface is very finely reticulated. The ground 
colour is rust-red, paler over the head, wings and limbs, all 
being streaked with dark purple-brown; the thorax and 
abdomen are speckled and blotched with the same colour. The 
surface is rather glossy. Pupal stage occupies about 30 days. 
Imago. The sexual difference is distinct. The average 
expanse of the wings in the male is 39 mm. ; in the female, 
37 mm * 
Male. ( Upper Side.) The colour is a very deep purplish- 
indigo-blue ; the marginal borders are black and broadest 
on the hind wings, which have vein two elongated and forming 
a short white-tipped black tail in both sexes. 
Female . The female is purple-velvety-black, with a large 
cloud of brilliant, lustrous purple filling the discoidal cell, 
and nearly the whole of the space between the lower veins, 
also a small patch above, the black nervures divide the purple. 
The hind wrings are coppery-black. 
Both Sexes. ( Under Side.) The sexes are similar on the 
under side. The ground colour is pearl-grey. The fore wing 
has a faint brownish mark at the end of the cell. Between 
this and running parallel to the outer margin is a w'hite stripe 
bordered imvardly by brown ; this is followed by a series of 
dusky blotches, the lower ones are edged with orange. The 
hind wing has an angular white line crossing the wing and 
forming an incomplete W near the inner margin. There is a 
black and orange spot at the anal angle, and a sub-marginal 
orange-ringed black spot between veins 2 and 3, also a double 
row of whitish lunules parallel to the outer margin. The mar¬ 
gins are outlined with black and white.
