LYCANID. ARHOPALA. 257 
This genus contains but a single species, which occurs in Australia. It has densely hairy eyes 
while all 4rhopadas have them smooth,

EXPANSE; 6, 9, 2'1 to 2°4 inches. 
DESCRIPTION : “MALE. UPPERSIDE, Jo0/h wings pale violet-blue ; cilia dark brown. Fore 
wing with a whitish tint in the middle, a dark mark at the end of the discoidal cell, extreme edge 
of anterior margin dark brown, Hindwing with the ¢az/, and a short tuft at anal angle, dark 
brown ; abdominal margin creamy colour. UNbDeERSIDR, doth wings buff-brown. Forewing 
having near the base of the discoidal cell a small blackish spot, then a longer square one, 
and parallelly beyond this another squarish undulated spot; then a series of seven ovat 
and lunate spots across the wing, one between each veinlet, also some irregularly-shaped spots 
disposed at the posterior side of the median nervure, all these spots being encircled by a 
narrow white band; near and parallel with the exterior margin are twe series of pale white 
marks, the space between these being of a darkish brown. Hindwing with five black spots 
near the base (these spots on both wings forming a circle) ; beyond these are three, then two, 
and afterwards a series of somewhat smaller spots, this series ending upwards to abdominal 
margin in a long narrow mark, all being encircled as those in forewing; near and parallel 
with the exterior margin are markings as in the forewing ; near anal angle are disposed some 
patches of black and metallic blue. FEMALE. UPPERSIDE, doth wings bright cyaneous, with 
a broad blackish anterior and exterior margin. [Forewing with the white discal area larger 
than in the male, the disco-cellular spot larger and darker.] Hindwing, anal angle with two or 
three cyaneous lunar-shaped marks; abdominal margin of a creamy colour ; Jody dark brown. 
UNDERSIDE, Joth w77gs as in the male.” (Afoore, 1. c.) 
Occurs in the Sikkim tarai (but not in the hills) in July and August, it is alsu found 
at Jalpaiguri and eastwards throughout Assam, and the late Mr. H. M. Parish obtained it in 
July in the Chittagong Hill Tracts. It appears to be confined to the lower hills and the 
country at their feet. It is one of the largest, most beautiful, and distinct species, and cannot 
be mistaken for any other. It appears to be fairly common where it occurs, but is so delicate 
that it is hardly ever obtained in perfect condition. 
815. Arhopala opalina, Moore. 
Neélasera opalina, Moore, Proc. Zool. Soc. Lond,, 1883, p. 531, pl. xlix, fig. 1, wale. 
HasitaT: Khasia Hills. 
EXPANSE: 6, I°5 inches. 
DESCRIPTION: ** MALE, UPPERSIDE, oth wings pale purplish lilac-blue. Cilia cinereous- 
grey. UNDERSIDE, doth wings pale lilacine greyish-brown. Forewing with a white-bordered 
brown mark within the cell, a broad similarly-coloured mark beyond the cell, and a chain-like 
discal band, beyond which are two marginal slender, indistinct, whitish lunular lines ; posterior 
border of the wing greyish-white. AHndwing with three transverse basal, four subbasal, 
one disco-cellular, and a curved series of eight discal white-bordered brown spots, beyond 
which are two marginal whitish lunular lines, with a green-speckled anal spot.” (AZoore, 1. c.) 
Ihave not seen this species. From Mr. Moore’s figure, it appears to be a. miniature 
A. camdeo, Moore, but on the upperside is of a rather different shade, more lilac than blue, and 
lacks the irrorated discal white patch in the forewing which is present in 4. camdeo. The spots 
on the underside are less distinct, and are not outwardly defined with a fine white line as in 
A.camdeo. In the forewing is a spot at the base of the discoidal cell, a large quadrate one in 
the middle, a still larger similar one at the end, with a small spot at its inner lower angle at 
the base of the first median interspace ; the discal band consists of seven spots, the series 
slightly broken and shifted inwardly below the third median nervule, It is quite unlike any 
species known to me, and should be easily recognised if met with.
