outer margin of the hindwing, apart from the totally different underside, allows one 
easily to distinguish it. 
Female. Upperside, both wings brownish-fuscous. Hindwing with the anal 
border and tail whitish, a large spot at the base of which and the anal lobe blackish. 
Underside, both wings whitish. Forewing with a single ochreous-fulvous fascia beyond 
the disc catenulately sinuous. Hindwing with a slender interrupted flexuous striga 
beyond the disc, with two spots at the base of the tail powdered w T ith blue, and the 
anal appendage deepest black. This stands very close to M. jolcus, Felder, from 
Amboina, but a careful comparison sufficiently establishes the difference of the two 
forms. The fact that the only known specimens of M. iscibella and areca are all males, 
while those of M. jolcus and hamorta are females, confirms me in the supposition that 
here merely the sexes of two species may lie before us. The construction of the palpi 
in M. sugriva , isabella and areca on the one hand, and in jolcus and kamorta on the 
other hand, differs much, such as we see also in both sexes of other allied species. The 
last joint of the palpi of the female is more than twice as long as in the male. That 
M. areca and hamorta , both of them, differ from M. isabella and jolcus in the want of 
the first fascia on the underside of the forewing, and the spots on the basal half of the 
same side of the hindwing, may speak in favour of the foregoing supposition.

Habitat.— Nikobar Islands. 
Distribution. —A common species in the Nikobars, occurring in Kamorta, 
Nankowri, Kar Nikobar, Little Nikobar, and Great Nikobar; this species is quite 
distinct from B. kamorta , Felder, of which there are both sexes in the B. M.; we 
figure Felder’s type male, which is in fine condition; w T e have not been able to obtain a 
female.

Imago. —Male. LTpperside black. Forewing unmarked. Hindwing with some 
greyish-ochreous at the anal angle ; tail greyish-ochreous ; anal lobe white, with an 
indistinct grey spot in it, much as in areca, but the ochreous space is more limited and 
* darker in colour, and the short black anteciliary line in that- species is wanting. 
Underside chocolate-brown, markings darker brown, with very fine pale edgings. 
Forewing with a short narrow basal streak, a broad outwardly curved band from near 
. the costa to the sub-median vein, a broad discal band with irregular margins, from the 
costa to the same vein, narrowing hindwards from its middle almost to a point; a 
sub-marginal series of spots and indications of a pale series close to the margin. 
Hindwing with three sub-costal spots in a line, two small spots near each other, sub-
