Z. marpissa Wllgr. (71 k). Thorax yellow mixed with brown, abdomen orange brown. Forewing yellow marpissa. 
wood-colour, veins 6 and 4, the median vein and vein i fine black. The inner margin, below the cell and between 
veins 2 and 4, the exterior portion of the cell, above and below vein 6 at the margin violettish-brown. Hindwing 
yellowish-white. 30—38 mm. East Africa, Transvaal, Natal. According to Janse spurcata Wlcr. is a synonym 
of it, whereas Aurivillius considers it to be cinerea Wlcr. 
Z. grisea sp. n. (71 k). Thorax yellow wood-colour, edged with a greyish violet, abdomen orange brown, grisea. 
Forewing pale wood-colour. Veins 6, 4, the median vein and vein 1 black. Costal margin as far as vein 6 and 
the base of the cell violettish-grey, also the space between veins 4 and 2, as well as below vein 1. At the ends 
of the veins black sagittae. Distal margin slightly notched. Hindwing white. 40 mm. Juba R. (East Africa). 
Type: 1 $ without antennae in the British Museum. 
In the two following species thefe males have short antennal pectinations. 
Z. trifasciata Hmps. (71 k). Thorax red-brown, in the centre darker. Abdomen ochreous-brown. Fore- trifasciata. 
wing ochreous-brown. In the cell a dark streak, also at veins 6 and 1. Median vein and vein 4 white, below it 
broad dark brown, somewhat less dark below vein 6 and towards the apex. Above vein 1 yellow wood-colour. 
Hindwing yellowish-white to brown. 30—42 mm. Gold Coast, Uganda, East Africa. 
Z. bossumensis Gaede (71 k). Similar to a faded trifasciata. On the forewing the distal margin and fringe bossumen- 
are very dark, the margin not so notched as in trifasciata. Above vein 1 not wood-coloured. Hindwing whitish, 
fringe very dark. 34 mm. Togo, Ivory Coast. 
The following species are very much alike and probably only f o r m s o f one 
species. Antennae of $ f i 1 i f o r m. 
Z. gallans Karsch. Thorax dark red-brown, abdomen ochreous. Fore wing at the costal margin wood- gallans. 
coloured yellow. Median vein and vein 4 almost to the margin black, below edged with red-brown. From the 
distal margin close under the apex to close above vein 4 a narrow dark red-brown triangle as far as the cell, 
its upper distinct border is angled once. Below the median vein as far as near the submedian fold whitish-grey, 
then as far as the inner margin red-brown. Hindwing yellowish-white, in the $ darker. 35 mm. Togo, East 
Africa. 
Z. anodonta Hmps. (72 a). The subapical spot is indistinctly defined. Between veins 2 and 4 greyish- anodonia. 
white, between veins 1 and 2 pale yellow, inner margin brownish. Hindwing mostly lighter. 35 mm. East 
Africa, Transvaal. 
Z. bidentata Hmps. Costal margin of forewing darker. The upper border of the triangular subapical bidentata. 
spot is white, twice notched. Vein 4 is white, the median vein is hardly pronounced. Submedian fold not grey. 
35 mm. South Nigeria, Togo. 
74. Genus: (SGuitliorioaita gen. nov. 
Palpi short, proboscis stunted, antennae of $ filiform. Forewing at the apex not so sharply produced 
as in Notoxantha. Vein 6 from the accessory cell, 7 -{-10 + 8 + 9 stalked from the apex of the accessory cell. 
In the hindwing veins 3 and 4 separated, 6 + 7 on a long stalk, 8 nearing the centre of the cell. 
H. debilis sp. n. (72 a). Thorax pale violettish-brown, abdomen whitish-yellow. Forewing creamy debilis. 
white, with a slight violet lustre. On the cross-vein, above veins 3 and 5 a greenish-yellow lustre. Before the 
distal margin and at it fine black dots. Hindwing pure white. In one specimen the forewing is dusted with 
violettish brown. 28—30 mm. West Tanganyika. Type: $ in the British Museum. 
75. Genus: EfotoxanilBa Hmps. 
Proboscis stunted, palpi short, porrect. Antennae of with long pectinations as far as the tips, in the 
7 filiform. Forewing at the apex sharply produced. Vein 6 from the cell-angle, 7 almost from the end of the 
accessory cell, 10 +8 +9 from its apex. In the hindwing veins 3 and 4 separated, 6+7 on a short stalk, 
8 nearing the centre of the cell. 
N. sesamioides Hmps. (72 a). Thorax pinkish white with a brown spot, abdomen brownish-yellow, sesamioi- 
Forewing pink, finely dusted with dark, median vein white and more feebly so veins 2, 4 and 6. Hindwing 
quite pale pink, feebly edged with brown. 30—34 mm. Ivory Coast, Angola, Transvaal. 
76. Genus: l*ol Semis Hist. 
Proboscis absent, palpi slightly upturned. Antennae of <$ up to the tips rather long-combed, in the P 
dentate. Forewing broad. Vein 6 below the upper cell-angle. Vein 7 forms an accessory cell by a bar with the 
stalk of 10 + 8 + 9. In the hindwing veins 3 and 4 are distantly separated, 6 + 7 on a long stalk, 8 nearing 
the centre of the cell and connected with it by a bar. Type: modestus Dist.
