wings diaphanous. — screabilis Wllgr. The grey places in the forewing are more contracted in the shape of 
stripes, affinis Brtl. and angolensis Brtl. are based upon too bad specimens as to be assigned to any form. 40 to 
55 mm. West and East Africa, Natal. 
S. jacksoni Bothsch. (13 c) resembles screabilis. Recognisable by the reddish-yellow veins in the forewing. 
Hindwing white, hyaline. 55 mm. East Africa, Abyssinia. 
S. lentifasciata Hmps. (13 c). The grey stripes on the forewing are only present below and behind 
the cell. Hindwing yellowish-white. 44 mm. Mashona Land. 
S. occidens Bothsch. (13 d). Thorax somewhat more brownish, hindwing more yellow. It scarcely 
differs from leyitifasciata. 30 to 50 mm. West Africa. — nyangweensis Strd. Similar to maclagascariensis, thus 
the forewings without markings, hindwings somewhat more scantily scaled. 36 to 46 mm. Congo. 
S. rhodesiana Hmps. (13 d). Similar to lutescens (13 c). Hindwing in the yellowish-white, in the 
$ orange. Abdominal rings broadly margined with black, whereby it is easily discernible. 42 to 52 mm. Mashona 
Land. 
S. penicillata Wkr. (13 d) is smaller, squatter. The grey places of lutescens are here brown. Hindwing 
also in the <$ orange. 36 to 46 mm. Sierra Leone, Niger District. 
The following species are similarly marked in the forewings, but also on the 
hindwings more or less black. 
S. leighi Bothsch. (13 d). Thorax and abdomen orange; the latter with black dorsal spots. Eorewing 
orange; veins lead-coloured, between them darker stripes. Hindwing orange, mostly with a large black central 
spot. 40 mm. South Africa. 
S. scita Wkr. (13 d). Thorax greyish-brown, abdomen orange with black ring-margins. Forewing 
orange on the veins, between them greyish-brown. On the hindwing the spaces between the veins are blackish- 
brown, only the hind-margin is orange. 40 mm. Natal. 
S. latiradiata Hmps. (13 e). Thorax with a black longitudinal streak. Costal margin, hind-margin, 
and median vein broad light orange. Spaces between the veins black. Hindwing likewise darker than scita. 
It may be the $ of scita-A. 44 mm. East Africa. 
The following species dark with large spots. 
S. melanodisca Hmps. (13 e). Thorax and forewing reddish-brown. A proximal line of black dots on 
the forewing is in the centre excurved. On the median line of dots a large spot as far as the cell-end. The distal 
row is only indicated. Marginal dots black. Hindwing dingy yellow with a black central spot and some 
submarginal ones. Forewing of the $ lighter red-brown. 35 to 38 mm. Uganda. 
S. rufa Joic. Similar to melanodisca. Thorax brown. Abdomen above pale pink with black dorsal 
spots. Forewing reddish-orange with 4 lines of black dots on the veins, which may also be absent. Hindwing 
somewhat pink with a black spot on the cross-vein and before the distal margin. 34 mm. East Africa. 
S. sjoestedti Aur. (13 e) is placed to the genus Pericallia by Hampson. ($)■ Pale brown with a proximal 
and median band of large black spots edged with white, in the centre angular. Around the cross-vein a very 
large black spot parted white by the veins. At the apex, before the margin and at the margin spots surrounded 
by white. Hindwing with a large central spot and smaller marginal spots. 45 mm. A smaller, lighter. Cameroon. 
Group II. Antennae of the A doubly dentate. 
S. lineata Wkr. ( = simplex Wkr., alba Wallgr., puella Drc.) (13 e). Thorax yellowish-white, abdomen 
orange with black dorsal dots. Wings white. On the forewing the veins are black. Hindwing at the hind-margin 
somewhat orange. — In albida Brtl. the veins are not black. Sometimes the dorsal spots are united in the centre, 
whereby a resemblance with Ams. grammiphlebia (14 h) is produced. 28 to 38 mm. East Africa, Delagoa Bay, 
Natal. 
S. eugraphica Wkr. (= undistriga Fldr.) (13 e). Orange-yellow. Abdomen with black spots or rings. 
Forewing with 2 dentate distinct black lines. Hindwing with a black central dot. 42 to 48 mm. Transvaal, 
Natal. 
S. bufti Bothsch. (13 f). Only the abdomen is orange, otherwise yellowish-white. The two lines of 
the forewing nearing each other at the hind-margin and connected there. 38 mm. Cape Colony. 
S. nyasica Hmps. (13 g). Thorax and forewing yellowish-white. Hindwing and abdomen orange- 
yellow with black dorsal dots. Eorewing with 2 rows of black dots, sometimes interrupted, the distal line in 
a curve around the dot at the cross-vein. Hindwing with a black central dot. 36 mm. Central Africa. 
S. togoensis Brtl. (13 g) is quite different. Thorax and forewing orange-brown, abdomen and liind- 
wing orange-yellow. On the hindwing a large black central spot, on the forewing a smaller one which may also 
be absent. 38 to 44 mm. Togo, Fernando Po.
