A. himalayana Mr. Body and wings dark brown, thorax still darker. Veins 7 + 8 + 9 of forewing himalaya- 
stalked. (JIB mm. Dharmsala, Pundjab. The species has been mentioned already in Vol. II, p. 355. The type 
is so badly preserved, that it is of no use to figure it. 
A. exacta Joann. Uniformly blackish-brown above; frons, legs and abdomen beneath grey. Costal exacia. 
margin of forewing slightly curved, apex somewhat pointed. The sac is 20 mm long, 4 mm thick, of grey 
silk. + 13 mm. Tonkin. 
A. longicauda Warr. has been described as (?) Psyche, but placed to this subgenus by Hampson. Tho- Longicauda. 
rax and body with shagged blackish-brown hair, according to Hampson greyish ochre. Wings dull blackish- 
brown, forewing more densely scaled at the costal margin and thereby darker, diaphanous in the other places. 
According to Hampson, the wing is hyaline with some brownish ochreous and blackish-brown scales, and a 
brown costal margin. Abdomen with a long brown hair-tuft at the end. Vein 7 of forewing from the cell, veins 
4+5 stalked in both wings. + 28 mm. Campbellpore (India). 
A. canarensis Hmps. + uniformly copper-brown. Veins 4+5 stalked in forewing, 7 arises from the canarensis. 
cell. Vein 6 of hindwing arises at the centre of the cross-vein. + 24 mm. Canara. 
Subgenus: Brachycyttarus Hmps. 
Inner-marginal veins of forewing as hitherto, veins 4 + 5 and 8 + 9 stalked, 6 absent. Hindwing somewhat triangular. 
A. subteralbatus Hmps. (= subteralbatus Hmps.) (91 b). Body and wings dark brown. Only the hind- subter- 
wing beneath lustrous bluish-white. — The larval case is about 12 mm long and is said to be suspended on a 
thread. + 14 mm. Ceylon. 
A. griseus Joann. (90 h). Grey with white fringe, somewhat lighter on the hindwing. Forewing be- griseus. 
neath grey, hindwing white, legs and abdomen greyish-yellow. Forewing more rounded at the apex than in 
subteralbatus. — The sac is 13 mm long, very thick, very irregularly covered with stalks of grass. Suspend¬ 
ed for the pupation on a thread 10 mm long. + 14 mm. Tonkin. In the original figure the ground-colour 
is brown, not grey. 
Subgenus: C remast o psyche Joann. 
Antennae with long pectinations, gradually shortening towards the tips. Vein 1 b of forewing despatches a bar to the 
inner margin. Vein 5 is mostly present, 7 almost invariably absent, 8 + 9 mostly stalked. The hindwing almost invariably 
lacks vein 6. 
A. pendula Joann. Dark brown. Size and shape of wings as in Brack, griseus. Beneath the posterior pendula. 
tibiae and the abdomen are whitish, the hindwing bluish-white, only at the margin narrowly dark brown. — 
The sac is 8—10 mm long, 2—3 mm thick, suspended for the pupation on a thread 7—-12 mm long. + 14 mm. 
Tonkin. 
Subgenus: Pteroma Hmps. 
Antennae of + with very long pectinations. Inner-marginal veins as hitherto. Vein 6 + 7 absent in forewing, 8 + 9 
stalked, 11 anastomoses a little with vein 12. The hindwing lacks the upper part of the cross-vein and vein 6. 
A. plagiophleps Hmps. differs from subteralbatus (91 b) only in the antennae and the neuration. The plagio- 
larval case is the same as in subteralbatus, besides the suspending thread is spun with remnants of plants. 
+ 15 mm. Ceylon. 
Subgenus: Metisa Wkr. 
Only veins 8 + 9 of forewing stalked, vein 6 present in both wings. Veins 8 of hindwing branches off from the 
cell-end. 
A. plana (91 b). Body blackish-brown, with hardly any scales. Wings very pale brown, broad. + 15 mm. plana. 
Ceylon. 
A. canifrons Hmps. Uniformly blackish-brown, according to Joannis brown. Veins 7 + 8 + 9 of canifrons. 
forewing stalked. + 20 mm. Sikkim. 
A. hypoleuca Hmps. Pale brown. Forewing with a slight grey hue, costal margin dark. Hindwing with hypoleuca. 
a white apex. Fringe of both wings blackish-brown. Hindwing beneath white. + 20 mm. Ceylon. 
A. atra Joann. Forewing rounded, black, hindwing also round, jet-black, but less clad with white atra. 
hairs. Separated from the similar canifrons by the much darker ground-colour and larger hindwings. — The 
sac is spirally constructed, wound either to the left or right, spun parallel with fine sprigs of 8—10 mm 
length; 18—30 mm long, 4—8 mm thick. A similarly constructed sac is that of Mali, poliotricha and Cli. 
javana. + 18 mm. Tonkin. 
Subgenus: Amicta Heyl. 
The two inner-marginal veins of the forewing are not fused, the upper one is only short. The only Indian spe¬ 
cies shows vein 6 present in the forewing and 7 + 8 + 9 + 10 stalked.
