C. opalina Wkr. (= thymiathis Drc.% ) (22 h). Wings semi-transparent yellowish-white, apex and 
veins of forewing blackish-brown. South and East Africa. 
54. Genus: l*irga Auriv. 
Hind tibiae only with terminal spurs. EoreAving with accessory ceil, from which the veins 10, 7, and 
on a short pedicle 8 + 9 rise; vein 6 is distinctly separated from them, 4 and 5 distantly separated. In the 
hindwing vein 4 rises nearer to 5 than to 3, 6 + 7 forked, 8 separate, but close at the discal cell. 
P. mirabilis Auriv. Wings somewhat hyaline yellowish-white, distal margin broad black like the 
veins. Body blackish-brown, head, prothorax and end of abdominal segments partly ochreous-yellow. West 
Africa. 
P. magna Swh. (22 k) is smaller, in the forewing the distal black colour extends almost to vein 2, in 
the hindwing to the cell. British East Africa. 
P. loveni Auriv. is quite similar to magna (22 k). The border between the white and grey portions 
of the wing is indistinct, only in a certain light prominent, the white colour of the hindwing only extends to 
vein 1 a. Expanse: 46 mm. British East Africa. 
P. weisei Karsch (22 k). Wings uni-coloured hyaline grey, costa of forewing and the greatest part of 
the body blackish-brown. Usambara. 
P. luteola sp. n. Wings scantily scaled, ochreous-yellow. Forewing distally to the cell and in the 
hindwing a spot at the apex blackish. <$ type from Kassai, Congo, in the Berlin Museum. 
P. lufea Griinb. (22 k). Body and the hyaline wings ochreous yellow, antennae black, also part of the 
legs; an indistinct black transverse line through the cell before the end, extending behind the cell much farther 
distally, often undulate. Veins partly sometimes violettish-black. Dar es Salaam, Tanganyika. 
P. transvalensis Janse. Body ochreous-yellowisb, antennae black. Wings hyaline with yellowish hair, 
particularly at the base and hind-margin of the hindwing. Veins, distal margin and apex, costal margin of 
forewing, and hind-margin of hindwing brownish. Expanse: 33 mm. Transvaal. 
P. perfasciata Wichgr. is quite similar to lutea, but larger, band of forewing continued on the hindwing, 
fringes brown, not yellow. Tibiae and feet quite blackish-brown. East Africa. 
P. pellucida Wichgr. is like perfasciata , without dark transverse lines in both wings. Expanse about 
50 mm. German East Africa. 
P. mnemosyne Rbl.. (21 e). Body marked black and yellow. Wings not transparent yellowish-white, 
only the apical portion of the forewing, beginning from the cell, blackish hyaline, gradually narrowing down 
to the tornus, veins dark brown, in the hindwing less distinct. Apical portion of hindwing somewhat hyaline. 
Fringe brown. The specimen before me, from South Cameroon, shows 7, 8 + 9 in the forewing on a joint 
pedicle. Beni. 
P. bipuncta sp. n. is quite dissimilar to the other species, but with respect to the structure it belongs 
to the genus. In the habitus it is similar to Sapelia tavetensis Holl. Body whitish, head, antennae, and thorax 
in front ochreous-yellow. Forewmg white, hyaline; costal margin, apex, distal margin, and 2 dots on the cross¬ 
vein blackish. Hindwing hyaline white, margin fine black. G type from Kibwezi, British East Africa, in the 
Tring Museum. 
55. Genus: Kopirga gen.nov. 
Tibiae long-haired, hind tibiae with 1 pair of spurs. Palpi short, the 3rd joint almost hidden below T the 
hairing of the 2nd. Antennae relatively short. Forewing with an accessory cell which is rather long, similar 
to that of Marbla. Veins 10 and 7 rise in about the same height before the end of the accessory cell, 8 + 9 on 
a short pedicle from its end. 6 from it near its base. In the hindwing vein 4 is nearer to 5 than to 3,6 + 7 on 
a short pedicle, 8 closely approaches the anterior edge of the cell as far as its centre. Genotype: 
E. Candida sp. n. (26 h) is a large species. Body white, prothorax, head, and abdomen beneath ochreous- 
yellow. Tarsi outside black. Wings broadly rounded, above and beneath white, costal margin slightly darker. 
Expanse: 58 mm. $ type from Antanambe in the Tring Museum. Madagascar. 
56. Genus : Somatoxeiia Auriv. 
Like Pirga, but vein 6 rises from the accessory cell of the forewing, vein 7 from 8 + 9 or from 8. In 
the hindwing vein 8 is partly fused with the anterior edge of the discal cell.
