Ps. nigra Hmps. has already been dealt with in Vol. II, p. 362. The species is not figured there 
and the reference 56 g has to be cancelled. The species presumably occurs also in Indian districts. 
b) Veins 7 and 8 of forewing arise from the upper cell-angle, 9 a little 
more b a s a d. 
Ps. rotunda Hmps. (91b) is an insignificant blackish-brown little insect with broad rounded wings. 
16 mm. Ceylon. The larval case is clad with scales of bark and little pieces of stalk. 
Ps. decemvena Hmps. (Vol. II, pi. 56 g) has also been described in Vol. II, p. 362; it is separated 
from nigra Hmps. by the absence of vein 8 in the forewing. Cashmere. 
Subgenus: Barandra Mr. 
The two inner-marginal veins of the forewing are not fused here, but a ray extends from the lower one to the 
inner margin. Veins 8 + 9 stalked. Vein 8 of hindwing connected with the cell by a bar. Both wings lack vein 6. 
B. fumata Mr. Body brown, 2 dark spots on the mesothorax. All the wings uniformly pale brown. 
<$ 20 mm. Dharmsala. 
10. Genus: Acaiitliopsyclie Heyl. 
All that is necessary has been said about this genus already in Vol. II, p. 354. Antennae of pec¬ 
tinated to the tips, dents of pectinations decreasing in length from the middle. Anterior tibia with a long 
spine. 
Subgenus: Oiketicoides Heyl. (Oeceticoides Hmps.). 
Veins 1 b and 1 c of forewing fused in the distal half. Both wings lack vein 6. Vein 8 of hindwing connected with 
the cell by a bar. 
a) Veins 4+5 stalked in both wings, vein 7 of forewing from the ceil. 
A. bipars Wkr. Body black with white hair. Forewing hyaline, only the basal third smoky brown, the mar¬ 
ginal line and veins black. Two thirds of the hindwing beginning from the base are smoky brown, the margin 
and veins as in the forewing. $ 16—26 mm. This species is remarkably similar to Koph. weyersi Sn. and 
to the Lymantriid Pernia nuda F. (Vol. II, pi. 21 cl). Bombay. 
A. nigraplaga Wil. (Vol. II, pi. 56 g). Similar to bipars, but of a different neuration. The black mark¬ 
ing at the base of the hindwing is more extensive, less extensive on the forewing. The rest is hyaline. 
From Sikkim, Tonkin, also in Japan, therefore figured in Vol. II, pi. 56 g. 
A. elwesi Heyl. Body greyish-black, legs black, tarsi yellow. Forewing greyish-black, rounded at the 
apex. Hindwing round, cross-vein in front obliquely inwards. 18 mm. Ganjam. 
b) Veins 4 and 5 in both wings from the cell. Veins 7+8+9 of forewing 
stalked. 
A. cana Hmps. Head white, thorax and abdomen pale ochre. Wings greyish-brown. — Larval sac 
about 30 mm long, 6 mm thick, clacl with little remnants of plants. 23 mm. Ceylon. 
c) V e i n s 4 and 5 of forewing from the cell, 7 below the upper cell-angle. 
A. minor Mr. Body long-haired. Wings with small scales, pale copper-brown. Under surface paler. 
15 mm. Calcutta. 
d) Neuration not state cl. 
A. minima Hmps. Uniformly blackish-brown, wings thinly scaled with black hair, somewhat more 
densely only at the inner margin of the forewing at the base. Larva pricked almost to its extermination. 
r( 12 mm. Ceylon. 
Subgenus: Dasaratha Mr. 
Inner-marginal veins of forewing as in the preceding subgenus, vein 6 present, absent in the hindwing. The parti¬ 
tion-vein of the cell is forked in both wings, veins 4 and 5 of forewing not stalked, 7 + S + 9 stalked and then branching 
off at the same place.
