Cl. guineensis Strd. The sac recalls that of moddermanni. The branchlets are shorter, less smooth, the 
whole work not so carefully and regularly done. Spanish Guinea. 
Cl. junodis Conte and Vaney. I had no access to the description in Lab. Et. soie Lyon Vol. 14, p. 123. 
2. Subfamily: Psychinae. 
In t li e f orewing veins 1 c and lb mostly anastomose, from lb b u t o n e 
branch goes to the inner margin. The cellular ray is plain or forked. An¬ 
terior t i b i a e with a spine or without it. Hind legs shorter than front legs. 
3. Genus: Acaiitliopsyclie Heyl. 
Antennae of $ pectinate to the tips, the dents from the centre gradually decreasing in length. Anterior 
tibiae with a very long spine. This principal genus exhibits numerous small differences in the neuration, which 
made it necessary to establish subordinate genera. 
Subgenus: Oeceticoides Heyl. (Oiketicoides). 
In the forewing veins lb and 1 c anastomose, vein 7 is absent in both wings; in the hindwing vein 8 is connected with 
the cell by a bar. Type: inquinata Led. from Europe. 
A. tristis Janse belongs to Hampson’s Sect. III. Body cinnamon-red and brown. Wings moderately 
densely scaled dark brown. On the forewing the exterior half and on the hindwing the distal third somewdiat 
more hyaline. In the forewing veins 2—9 somewhat darker, the costal margin and in both wings the distal 
margin blackish brown. 20 mm. Natal. — Shape of sac most variable. 
A. carbonarius Karsch (72 i). Body and wings uniformly dark brown, but the marginal area in the 
same extent as in tristis quite hyaline (at least in the type). Head remarkably white. Expanse of wings: 
17 mm. Togo. 
A. sierricola White presumably also belongs to this genus. Separated from carbonarius by the white 
long hair on the thorax. Size not stated. Sierra Leone. 
Subgenus: Dasaratha Mr. 
In the forewing veins 1 b and 1 c anastomose, all the veins are present; in the hindwing vein 6 is absent, 8 is connected 
with the cell by a bar. Basal ray at both the cells forked. Type: himalayana Moore. 
A. junodi Heyl. Blackish or blackish-brown. Body above with long blackish-brown, on the sides with 
greyish-brown hair. Forewing somewhat oblong, rounded at the apex. Both wings with long black hair, the 
veins prominently black. In the forewing veins 4 + 5 on a short stalk, 8+9 on a long stalk. In both wings 
the cell is very long. The yellow female with small yellow antennae and black eyes. The 3 first segments lustrous 
yellow, then greyish yellow, more or less covered with greyish-yellow wool. The sac is pear-shaped, lengthways 
irregularly covered with pieces of leaves and twigs, 50- 55 mm long, 20 —28 mm thick; expanse of wings: 
26 mm. Natal. According to Janse the wings are hyaline, colourless. Forewing as far as the centre (only 
at the inner margin somewhat farther) covered with blackish-brown hair, on the hindwing only at the inner 
margin. 
Subgenus: Semimanalha Janse. 
In the forewing veins 1 b and 1 c anastomose, vein 7 is absent, 8 + 9 are stalked. In the hindwing all the veins are 
present, vein 8 is free at the base, then it anastomoses with the cel! almost on its whole length. This subgenus is distinguished 
by the straight costal margin of the forewing. Type: jumosa Janse. 
A. fumosa Janse. Body above scantily olive brown, beneath white-haired. Both wings uniformly and 
rather densely haired olive brown. Costal margin of forewing with a fine black line to the apex. 19 mm. Natal. 
Subgenus: Metisa Wkr. 
Separated from the preceding subgenus by the presence of vein 7 in the forewing. Veins 4 + 5 in both wings stalked. 
In the hindwing vein 8 is very much fused with the cell. Costal margin slightly rounded, as in the other subgenera. Type: 
plana Wkr. from India. 
A. alba Janse (72 i). Thorax with white, abdomen with white and dark brown hairs. Wings without 
any scales, only at the inner margin of both wings a few white hairs. Costal and distal margins fine dark 
brown, the latter slightly concave at vein 2, particularly on the hindwing. 25 -29 mm. Natal. — Larva on a 
species of Acacia.
