LYCANID. ACESINA. 281 
straight, outwardly oblique; lower disco-celiular also straight, but inwardly oblique ; second 
median nervule originating some little distance before the lower end of the cell. In the hind- 
wing the costa is shaped very much as in Arhopala ganesa, Moore, but is not quite so emargi- 
nate just before the apex, and the apex itself is a little less produced ; the first subcostal 
nervule is given off long before the apex of the cell; the upper disco-cellular nervule is 
a little shorter than the lower, straight, outwardly oblique ; the lower disco-cellular is also 
straight, but is inwardly oblique; the second median nervule originates a short distance 
before the lower end of the cell. No secondary sexual characters in the male. 
This genus has been so recently established that I am unable to say with exactness either 
the number or the distribution of its species. In India it contains but two species, one of 
which occurs from Nepal to Assam, the other in Upper Tenasserim, The sexes of A. paraganesa 
mihi, are nearly alike, having small patches of blue on the upperside of both wings 
confined to the disc and base. In A. aderrans, mihi, the sexes are very different on the 
upperside ; the male being, except fer a very narrow outer black border, entirely purple-blue, and 
the female marked like the other species. I have taken A. faraganesa in Sikkim ; it inhabits 
forests, and settles only on the leaves of trees and bushes, ard has rather a weak flight. 
The markings of the underside are closely similar in both species to those obtaining in the 
genus Arhopala, Boisduval, from which Aceszxa is structurally hardly separable, 
Koy to the species of Acesina.

EXxpaNSE: 6, 9, 1'2 to 14 inches, 
DEscRIPTION: ‘* Nearest to Panchala [=Arhopala] ganesa, Moore. UPPERSIDE, both 
wings violet-brown, with the discal areas of a purplish-violaceous blue. Forewing with the 
blue colour confined to a narrow oval area, including the cell. Aindwine with a long slender 
tail from the end of the first median nervule; the blue colour confined to the medial area; a 
marginal row of indistinct whitish double lunules. UNDERSIDE, dof wings with similarly 
disposed markings to those in P. ganesa, those on the forewing being dark chocolate-brown, 
and the interspaces between the cell-marks also of the same colour. Hindwing with chocolate- 
brown markings and basal interspaces, the markings also mostly with pale centres.” (AZoore, 
1, c. in Proc. Zool. Soc. Lond., 1883.) 
The above description evidently applies to the female; the male differs in having the 
blue coloration on the upperside of both wings more extensive, and marked on the forewing 
with whitish between the veins beyond the end of the cell; hindwing blue, the costal and 
outer margins black, extending decreasingly up the veins from the outer margin. Cilia in 
both sexes brown at the apex of the forewing becoming white towards the anal angle, white 
on the hindwing becoming brown towards the anal angle. 7Zai/ brown, tipped with white. 
Rare in Sikkim, where it occurs in April, May, and October. I have seen one specimen 
from Sylhet obtained by the Revd. Walter A. Hamilton.
