464 LYCANIDA, ~ RAPALA, 
yellowish-grey, witha slender darker line, posteriorly undulated, Aindwing with two black 
ocelli, the second marked with red.” (Xod/ar, 1. c.) 
MALE. UPPERSIDE, doth wings shining bluish-purple or deep steel-blue, variable in 
shade. Forewing with the costa, apex and outer margin purplish-black, sometimes without 
any other marks, sometimes with a small orange patch beyond the cell, sometimes with a patch 
nearly as large asin Aysudra selira, Moore. Hindwing with the costal margin pale, the 
abdominal margin fuscous, the anal lobe black, with a patch of ferruginous scales near the 
middle. UNDERSIDE, doth wings with the ground-colour somewhat variable in tone, some- 
times pale brown, sometimes ochreous-brown. Forewing with two fine dark lines defining the 
disco-cellular nervules ; a very straight, even, decreasing discal band from the costa almost to 
the submedian nervure, outwardly finely defined with white ; an obscure submarginal fascia. 
Hindwing with similar markings, but the discal band recurved to the abdominal margin, where 
it is defined on both sides with white ; anal lobe black, submedian interspace on the margin 
also black, but heavily sprinkled with whitish scales, a black spot crowned with orange in the 
first median interspace. FeMALE. UPPERSIDE, doth wings rather duller in shade, otherwise 
similar to the male. ; 
‘A variable species. The male is sometimes, as in Kollar’s figure, without the red spot 
on the middle of the forewing ; sometimes it is more distinctly marked than in the figure 42 of 
the plate. In colour it differs from other allied species, and, like the females of X. varuna, 
Horsfield, and 2. pheretima, Hewitson, [a Bornean species], is of a dull grey- or indigo-blue, 
On the underside the transverse band is far apart where the wings meet.” ( Hewi¢son, 1. c.) 
In Sikkim, as elsewhere, this is a very variable species, some specimens of both sexes 
showing no trace of the discal orange spot on the upperside of the forewing, others having it 
quite small, while others again have it very large. It occurs in Sikkim in Mares April, Mey 
August, September, and October. 
Mr, Doherty (I. c.) remarks :—‘‘ Kumaon specimens rarely show any trace of the red spot 
above, and are of aricher metallic above anda deeper rufous below than Simla specimens. 
The genus [Bidasfa] seems very close to fafgala.” Colonel Lang writes of this species :— 
6 Scarce or local at Naini Tal, a few taken in May, July, and September, 4,000 to 6,500 
feet. Generally shot with steely-blue without any patch, but one or two with a dull fulveres- 
cent patch.” 
R.nissais probably confined to mountainous districts, and where it occurs is by no 
means rare. It has so far not been recorded from the Malay Peninsula, but the hill ranges 
in that region have been very slightly explored entomologically. I possess two specimens 
from Sumatra which only differ from Indian examples in the discal band on the underside 
of both wings being filled in with ochreous. Mr. Butler evidently does not admit the generic 
distinctness of Bidasfa, as in 1886 he quite correctly places this species in the genus Rapala, _

DESCRIPTION: ‘* MALE. UppErsIDk, doth wings dark dusky blue borders black. UNDER 
SIDE, both wings pale vinous brownish-buff, crossed by a straight narrow tapering dark brown 
pale-outer-bordered band, a paler cell-streak, and an indistinct brownish submarginal fascia 5

Ihave not seen this species. In many respects the description agrees with my #. Zara, 
but the anal lobe and black spot beyond in that species are not ‘speckled ochreous and white,”
