NEW NORTH-EASTERN SUMATRA BUTTERFLIES. 39 
Description: MALE, UPPERSIDE, both wings very deep and rich velvety 
dead black. Forewing with a rninute costal white dot placed between the 
first and second subcostal nervules; four subapical spots—the uppermost small 
and oval placed between the fourth and fifth subcostal nervules, the second and 
third much larger and oval placed in the subcostal and upper discoidal inter- 
spaces, the fourth equal in size to the first placed in the lower discoidal 
interspace. In two specimens there is a fifth smallest spot on the costa placed 
between the third and fourth subcostal nervules. ‘This series of spots is placed 
obliquely outwards and appears to run into and coalesce with the marginal series 
at the eighth spot (counting from the apex),which latter series consists of fourteen 
small spots, decreasing in size from the inner angle to the apex, placed in pairs 
in the interspaces ; the two sexual brands as usual in the submedian interspace— 
the upper short and narrow, the lower broad and twice as long as the upper. 
Hindwing with the costal area broadly whitish, followed by a broad pale 
castaneous area reaching to the middle of the discoidal cell, the abdominal area 
fuscous, all the rest of the wing deep black as in the forewing ; a marginal series 
of thirteen rounded spots, with an inner series of seven spots from the second 
subcostal nervule to the submedian nervure. In two specimens these two serieg 
of spots, instead of being quite distinct and well separated, completely coalesce 
and form short streaks. UNDERSIDE, both wings olivaceous-fuscous, the marginal 
series of spots as on the upperside. orewing with an additional small spot 
at the lower outer end of the discoidal cell, two on the costa making a complete 
series one in each interspace divided by the subcostal nervules, and two in 
each median interspace ; the inner margin broadly shining fuscous. Hindwing 
with two additional spots to the inner marginal series placed anteriorly, and a dot 
in the second median interspace just beyond the end of the cell. Cilia of both 
wings alternately black and white in equal proportions. Frmane. Upprrsrpe, 
both wings very much paler than in the male, black, but not of a deep, rich, 
velvety shade. orewing with three costal spots in a cluster: a complete 
submarginal series of eight spots ; two small spots inthe median interspaces ; 
the marginal series of spots as in the forewing, but rather larger. Hindwing 
with the two marginal series of spots almost sitely coalesced into streaks ; only 
anteriorly are they free. UNDERSIDE, both wings coloured as in the male, 
Forewing as on the upperside, but the two spots in each of the median inter- 
Spaces larger ; the inner margin broadly white; a short white streak in the 
submedian interspace. Hindwing as on the upperside, but with an additional 
spot at the outer end of the cell, and a complete series of five beyond the 
cell—one in each interspace, 
I know of no species with which this can be compared. The beautiful deep 
velyety black of the male on the upperside is only matched, as far as I know,
