then excurved. A curved subterminal band of spots with dark and silvery scales from the costal margin to vein 2. 
At the apex a dark brown spot. Hindwing yellow, with a reddish tint, fringes at the ends darker red. Under 
surface yellow, forewing suffused with reddish. Expanse: 18 mm. Somaliland, April. 
6. Genus: C'lirysamma Karsch. 
Antennae in the <$ long-combed to the tips, in the $ almost bare. Palpi short, porrect. Hind tibiae 
with 1 pair of spurs. In the hindwing vein 8 near the base connected with the cell by a cross-vein, 6+7 stalked: 
in the forewing 7 forked with the stalk of 8 + 9, vein 10 straight. 
Ch. purpuripulcra Karsch (= purpuripulchra v. cl. E.) (73 b). Forewing in the basal two thirds purple purpuri- 
red, densely strewn with dark brown and silver, in the distal third of a glaring yellow colour, with an arcuate pulcra 
row of black dots. Hindwing unicoloured yellow, but often in the basal two thirds red. Under surface sulphur 
coloured, basally more or less red. French Guinea to Cameroon, Transvaal, Southern Sudan, German East 
Africa, range probably still larger. 
7. Genus: Hllipoda Karsch. 
$ with plain antennae, palpi very short. Hind tibiae with one pair of very short spurs. In the hindwing 
vein 8 near the base connected with the cell by a cross-vein, 6 + 7 stalked. In the forewing 7 forked with the 
stalk of 8 + 9, 10 straight. But one female has been ascertained. 
H. gravidipes Karsch (73 b). Thorax above green, abdomen ochreous. Forewing green, with a broad gravidipes . 
red-brown marginal band and a broad longitudinal stripe from the base. Hindwing and under surface ochreous, 
abdomen beneath red-brown. Togo. 
8. Genus: Trypliax Karsch. 
Hind tibiae with 2 pair of spurs, with shaggy hair. Palpi thick, distinctly projecting beyond the frontal 
tuft, the last joint in the $ much longer than in the + Antennae of $ in cinereus in the basal halves with long 
pinnae, in the distal halves bare, in the $ entirely bare. In the hindwing vein 8 near the base connected with 
the anterior edge of the cell by a cross-vein, 6 + 7 stalked. In the forewing 7 forked with the stalk of 8 + 9, 
10 straight. 
T. cinertus Holl. (73 b). Forewing grey, more or less mixed with reddish-brown, markings mostly cinereus 
indistinct, blackish: a zigzag line from % of the costal margin to before the centre of the inner margin, another 
line begins at the costal margin between this line and the apex almost parallel to the margin, but it ends already 
above the centre of the wing and is mostly continued as a row of dots close at the margin to the tornus. An 
antemedian zigzag line is mostly indistinct. Hindwing grey, fringes of both wings with a yellow basal line. 
Thorax above more or less yellowish. Under surface wood-brown. Nigeria, Cameroon, Gabun. (According 
to Atteivillius also Natala undina Drc. belongs to this place.) 
T. vigoralus Karsch (73 b). Antennae of very shortly pectinated to the tips. Forewing brownish vigoratus. 
grey, markings extremely indistinct, in an oblique exposure to light we notice a red-brown transverse line 
proceeding from the costal margin shortly before the apex, extending almost parallel to the margin and exhibiting 
two intense indentations towards the margin, from the anterior indentation starts a more red-brown broad 
transverse shadoAV not reaching to the inner margin. At the cell-end a feebly darker spot. Hindwing and under 
surface lighter brownish-grey. But one male known from Togo, Misahohe. 
T. uelleburgensis Strd. (73 d). Forewing light grey, almost the whole basal half red-brown, of the same uelleburgen- 
colour a subterminal line which shows indentations towards the margin and which on the basal side is accom¬ 
panied by a broad red-brown nebulous band already from the costal margin to the inner margin; at the interior 
angle the line is connected with the margin by a brownish-red spot, at the cross-vein there is a red-brown 
transverse streak. Hindwing reddish brownish-grey. Under surface of forewing brown, of hindwing vellowish- 
grey, with brown internerval marginal spots, the size of which decreases much in size from the apex to the anal 
angle. But one female known from Uelleburg, West Africa. 
T. expers Karsch (73 d). <$ with short pectinations as in vigoratus. Described from a much flown q expers. 
likewise distinguished by abundant brownish-red colouring, but the subterminal line is hardly excurved and 
nearer to the margin, its proximal broad shading only begins far below the costal margin. Hindwing and under 
surface lighter brownish-grey. Quango. 
9. Genus: Oephyropliora Karsch. 
Hind tibiae with 2 pair of spurs, thinly haired. Palpi of $ and 2 long, with a long drooping distal joint. 
Hindwing with a cross-vein near the base between vein 8 and the cell, 6 + 7 stalked. In the tore wing 7 stalked 
with 8 + 9, 10 straight. Antennae of £ (also of $ ?) with short pectinations to the tips. 
G. mitis Karsch (73 c). Forewing red-brown, strewn with a darker colour, with 2 dark transverse lines mitis. 
from the costal margin before the apex, divergent towards the inner margin and distally convex. Hindwing 
and under surface unicoloured red-brown. Togo.
