LYCANIDE. ARHOPALA. 253 
Mr. Moore compares it with 4. areste, Hewitson, but as that species has no tail, in my opinion 
the two species are very distantly related. It is possible that Mr. Moore has failed to correctly 
identify 4. areste, as he has attached that name to specimens of both sexes of A, adriana,

Hapsitat : Sikkim. 
Expanse: ¢, 1'6 to t'9; 9, 1°65 to 1‘8o inches, 
DESCRIPTION : “ MALE. UPPERSIDE, both wings as in N.[=A.] asoka, de Nicéville, but 
the black bordering at least twice as wide. UNDERSIDE. Forewing marked as in NV. asoka. 
Hindwing dark brown glossed almost throughout with pale violet-grey, but exceedingly 
variable, in some specimens the ground-colour is very pale, the markings therefore being very 
prominent, in others so dark that they are hardly traceable ; three subbasal small round 
spots, a chain of spots from the costa to the middle of the cell, another chain also from 
the costa crossing the cell at its end, a third chain from the subcostal nervure to the abdominal 
margin, a submarginal lunulated line, but no black, green-irrorated, anal spots, which at 
once distinguishes this species from MV. asoka, FEMALE. UPPERSIDE, both wings as in 
NV, asoka, but the blue colour of amore purple shade. UNDERSIDE as in the male.” 
‘* This is apparently one of the commonest ‘ hair-streaks’ in Sikkim.” (de Miécéville, 1. c.) 
This species also has a limited range, Sikkim being the only locality I know for it.

DESCRIPTION: “ MALE. UPPERSIDE, oth wings covered on the whole surface, excepting 
a very narrow posterior black marginal thread, with a saturated purple tint, reflecting in a 
certain light a cyaneous gloss, or transmitting in another aspect the blackish ground-colour 
with a faint livid lustre. UNDERSIDE, é0fh wings, the ground-colour is deep brown with a 
reddish cast, and marked with broad cinereous slightly yellowish bands, and with occasional 
pearly spots; the tip of the forewing, and the whole surface of the hindwing, being covered 
with a purple reflexion ; the wings bear individually, at the base, near the costa, an oblique 
attenuated streak of a deep crimson shining tint. /ovewing has further three grayish bands, 
of which the first is abruptly terminated before the disc, and often appears in the form 
of a short stigma, the two others are terminated in the anal region at a small distance from the 
inner margin ; the exterior band is often undefined and spreads diffusely to the margin ; in some 
specimens a few minute grayish dots stand near the base. Hindwing, the basal portion is dark 
brown ; a broad cinereous band, highly tinctured with purple, occupies the medial portion, 
bearing a compound brown band faintly bordered with gray, consisting in the costal area of a 
short simple brown patch to which two parallel bands are joined, the anterior being interrupted, 
the posterior continued and united with a deep ferruginous blackish-brown band which passes 
in an arch across the disc ; exterior to this are a few obsolete dots near the posterior margin, 
being defined internally by a narrow waving blackish striga ; the dots towards the outer apical 
angle are very faint, but in the anal region are ¢wo pronounced black saédocellate spots, the 
exterior being placed between the tails, and the other, which is largest, at the extreme anal angle ;
