2. Genus: Pseudostracilla gen. nov. 
Separated from the two following genera by vein 11 rising separately from the cell. 
Ps. infausta sp. n. (19 b). Greyish-white, wings transparent, veins distally somewhat darker. At 
the rise of veins 3 and 4 a blackish vein-spot. 2 $ from Sierra Leone in the Berlin Museum. 
3. Genus : Pterocerota Hmps. 
Antennae of $ and $ pectinate, forewing without an accessory cell, only with 11 veins, vein 10 being 
absent, 11 fused with 12. 
P. virginea Hmps. is of a pure white, with a pale yellow frons and brown antennae. Anterior hips 
yellowish, tarsi brown. Wings diaphanous with an indistinct hyaline line beyond the centre, beyond the cell 
very convex and with 2 bent subterminal lines. Expanse of wings: 62 mm. Natal. 
4. Genus: €)|>ohoa Tessm. 
Allied to the preceding genus, but vein 11 not fused with 12 on the forewing. 
0. bolivari Kheil (= sexguttata Tessm.) (19 b). Body greyish-white, wings hyaline, forewing with 
a black dot at the base below vein 1 c and submarginally below vein 7, in the hindwing a similar submarginal 
dot below vein 6. West Africa. 
0. vitrea Auriv. (described as Stracena ) has no dot at the base and in cell 6 of hindwing, otherwise 
as bolivari. West Africa. 
0. schutzei Tessm. (19 b). Smaller, body more white, wings hyaline, forewing only with a basal clot, 
hindwing with a blackish transverse line in the centre, not reaching the costal margin and hind-margin. Nigeria. 
5. Genus: Miforildes Drc. 
Forewing with 12 veins, without an accessory cell, antennae in the <$ and $ pectinate. The genus is 
interesting for its sexual dimorphism. The $$ quite differently coloured from the <$<$, and by the contours 
of their wings and their colouring they recall Acraeidae. 
H. norax Drc. (= [Anengyai] spiritalis Karsch) is cpiite similar to the following, but the thorax is 
white, the wings are whiter, the central vein of the cell in the forewing bifurcates sooner, so that its lower 
branch is directed upon the rise of vein 3. Congo, Rhodesia. 
H. venosa Ky. (19 c). Thorax yellowish, in front orange-yellow, central vein of the cell terminating 
in its lower branch above vein 3. Rhodesia, Transvaal, East Africa. Different $-forms have been described: 
— crawshayi Btlr. (= craushayi Hmps.) is in the forewing diaphanous pinkish-brown, veins thinly black, 
a black streak at the cell-end, distal margin dark grey, proximally dentate, at the apex broadest. Fringes grey, 
at the tornus brownish. Hindwing reddish brown with a black spot on the cross-vein and a black marginal 
band which contains 6 dots of the ground-colour. — fuscata form. nov. (19 c) has an entirely black forewing, 
only a broad band distally to the cell being red-brown, otherwise like crawshayi (type from German East Africa 
in the Berlin Museum). — ansorgei Ky. (19 c) has a white discal band in the forewing and reddish-yellow 
hindwings. — albopunctata B.-Bak. (= albescens Joic. Talb.) has a white instead of brown ground-colour 
of the hindwing and a white discal band on the forewing. — neavei Hmps. resembles crawshayi, but it has a 
broader marginal band of the hindwing, extending to the centre of the branches of the veins. •— The two 
forms H. norax and venosa probably represent a single species to which a large number of $-forms are to be 
added. The latter will probably be related to the Acraea which are similar to them. So for instance H. 
crawshayi is said to copy Acraea natalicaBsd. (Vol. XIII, pi. 55 f), H. neavi Hmps. to copy Acraea anemosa Hew . 
6. Genus: Janse. 
Forewing with an accessory cell, in the hindwing 8 for some distance anastomoses with the cell, accessory 
cell elongate. 
L. hyalina Janse (19 b). Uni-coloured white, palpi mixed with black hairs and with a black apex. 
Legs partly blackish. Wings hyaline, costal margin of forewing as far as % black. Expanse 32 mm. South 
Africa. . - .
