460 LYC/AENIDZE. ‘ RAPALA. 
EXPANSE: @, 9, I'I5 to 1'So inches. 
DESCRIPTION: “ MALE. UPPERSIDE, doth wings dark slaty-blue, [the lower discal area 
of the forewing and the disc of the hindwing shot with brilliant blue in some lights. Aind- 
wing with the abdominal margin pale fuscous, the anal lobe black, bearing inwardly a patch 
of dull ochreous scales, with a patch of long white hairs above the lobe, and a fine anteciliary 
white line, obsolete anteriorly]. UNDERSIDE, Jo/k wings buff-grey, crossed by a narrow 
discal band of two white lunular lines [filled in with dark brown], and a cell-streak ; [an indis- 
tinct submarginal fascia]. AMinzdwing with ablack anal spot bordered above with white, and 
another beyond [in the first median interspace] bordered with ochreous, [the space between 
these spots irrorated with greenish metallic scales, with a narrow band of the same colour 
above the anal lobe]. FEMALE. UPPERSIDE, doth wings purple-blue, borders slightly purple- 
brown.”. [Otherwise as in the male, but of course lacking the blue gloss]. 
“ Allied to D. [= #.] varuna, [Horsfield, a Javan species]. May be distinguished by the 
blue colour of the male pervading the entire surface of the upperside.” (Jfvore, 1. c.) The 
latter remark, is incorrect, the blue gloss does not nearly cover the entire surface. 
“ Very common throughout the year in Calcutta. I have bred the larva in the Spring 
from Antidesma Gaesembilla, Mull., a deciduous bush growing in the Botanical Gardens. The 
larva and pupa agree exactly with the figures of an undetermined species given in Horsfield 
and Moore’s Cat. Lep. Ins, Mus. E. I. C., pl. xii, figs. 4, 4a, and which is probably Rafala 
varuna, Horsfield, a Javan species.” (de Micéville, 1. c.) The larvee are attended at all ages 
by a small black ant, Cremastogaster sp. The larva feeds on the just opening leaves, buds and 
flowers of the bush, and resembles them so closely as to be very difficult to find, though it is 
easily obtained by beating. 
** Distinguished by the beautiful blue of the hindwing and the basal part of the forewing, 
when seen in certain lights, especially from behind.” (Doherty, 1. c.) 
The rich, though restricted, blue gloss of the upperside of the males on both wings, and the 
narrow discal band on the underside of both wings, at once distinguish this species from 
R. orseis, Hewitson, which occurs in so many places withit. The females of 2. schzstacea, as far 
as I am aware, can only be distinguished from the same sex of &. orsezs by the discal band on the 
underside of both wings being narrower and more regular. It occurs on the lower outer ranges 
of the Himalayas as far west as Masuri at any rate, in Sikkim it is foundin April, June, and 
October, Colonel A. M. Lang has sent me a specimen taken at Bareilly in the North Western 
Provinces in December, it is common at Bholahat in the Malda district, in Calcutta, probably 
occurs throughout Assam, and is found in Orissa and southwards to the Nilgiris, and again 
in the Andaman Isles. In the Indian Museum, Calcutta, is an undoubted specimen from 
Ceylon, which is a new locality for it.

EXxpPaNSE: 6, 9, 1'5 to 1°6 inches. 
DESCRIPTION : MALE. UPPeERSIDE, Joth wings deep purple, almost dull black, but in 
certain lights the whole of the hindwing and the lower discal area of the forewing glossed 
with magnificent rich purple. Aézdwing with the anal lobe centred with ferruginous. UNDER- 
SIDE, both wings pale ferruginous towards the base, becoming gradually darker towards the 
margin. Forewing with a somewhat broad straight discal deep ferruginous band from the 
costa almost reaching the submedian nervure, its outer edge very even, its inner edge a little 
irregular. Aindwing with a similar discal band, but posteriorly curved up to the abdominal 
margin ; the anal lobe black, a deep ferruginous spot in the first median interpace on the 
margin, with some indistinct white speckles between, the discal band also bordered with white
