P. modestus Dist. (72 a). Ochreous white. Head and mesothorax red-brown. Forewing with a dark 
brown streak on the median vein and vein 4. Hindwing pure white. 30 mm. Natal, Transvaal, Rhodesia. 
P. ochraceus B.-Bak. (72 a). Body greyish ochreous. Forewing greyish-ochreous with dark scales 
below the cell. A dark patch above vein 4 and an oblique one to the apex. Hindwing unicoloured dark grey. 
34 mm. West Africa. A specimen from West Tanganyika exhibits a distinct exterior row of dots on the forewing 
and traces of an interior row. Hindwing at the margin brownish. 
P. fuscata Janse (72 a). Thorax yellowish-white, in the centre brown, abdomen creamy white. Forewing 
yellowish-white, dusted with blackish. Traces of a median and exterior blackish line. Brownish ochreous bands 
from the beginning of vein 3 to the end of vein 4 and one from vein 5 to the apex, between them a large radial 
stripe. Below them a short stripe from % of the inner margin. Hindwing blackish-brown. 38 mm. Transvaal, 
South-West Tanganyika. 
P. nigrosparsa Janse (72 a). Forewing without the dark bands of fuscata, veins lighter, the spaces 
between them densely dusted with dark. 40 mm. Rhodesia. 
P. albescens sp. n. (72 b). Thorax and abdomen brown mixed with white. Forewing creamy white, 
dusted with brownish. An exterior row of black dots, strongly excurved below the costal margin, to the centre 
of the inner margin. From the apex a fine brown line towards the centre of the inner margin, a feebler one 
from the centre of the distal margin. Hindwing almost white. 34 mm. Tanganyika, in the district of the large 
craters. It may be an alpine form of fuscata. Type: 1 $ in the British Museum. 
77. Genus: l T ti<laviniia gen. nov. 
Palpi short, proboscis present. Antennae of $ filiform. Costal margin of forewing almost straight, apex 
pointed, distal margin almost vertical to the inner margin. Veins 3 and 4 distantly separated, 6 below the upper 
cell-angle, 7 -(- 10 -j- 8 -j- 9 stalked. In the hindwing veins 3 and 4 distantly separated, 6 -f 7 on a short stalk, 
8 parallel to the cell on its whole length. 
U. citana Schs. (72 b). Thorax blackish-brown, abdomen dark brown. Forewing at the base and costal 
margin blackish-brown. Cross-vein black with a dark ring. Distal margin at the apex narrowly, at the inner 
margin somewhat more broadly red-brown; before it yellow wood-colour with a ray on the median vein. Before 
the distal margin yellow and black dots. Hindwing dark brown. 28 mm. Sierra Leone, Togo, East Africa. 
78. Genus: l®,v«Iaa Wkr. 
Proboscis stunted. Palpi long, erect. Antennae of £ pectinate, in the 2 plain. Forewing at the apex 
somewhat pointed, distal margin rather straight. Veins 3 and 4 separated. Vein 6 either from the cell-angle 
or stalked with 7; 7 —(- 8 —(- 9 -|- 10 stalked; or 10 forming with 7 -f- 8 + 9 a short broad or long narrow acces¬ 
sory cell. In the hindwing veins 3 and 4 separated, 6 -j- 7 stalked. A bar from vein 8 to the cell only indicated. 
Type: testacea Wkr. from India. 
A. Forewing without an accessory cell. 
P. rubritincta Hmps. (72 b). Thorax greyish-brown and red-brown, abdomen ochreous brown. Forewing 
ochreous grey, between the veins red-brown, except at the costal margin and base. An oblique curved exterior 
row of blackish-brown dots and one before the distal margin. Hindwing reddish-brown. 40 mm. Natal, Gold 
Coast, East Africa. It may be Not. brunneomixta Mab. (1897). 
P. brunnea sp. n. Thorax and forewing dark reddish-brown. An interior row of 3 black dots and a 
curved exterior row; between these rows the veins are lighter. Abdomen and hindwing dark brown. 26 mm. 
Type: 1 in the Berlin Museum. 
B. Forewing with a broad accessory cell. 
P. flavida Hmps. Thorax whitish ochreous, abdomen yellowish-brown, at the end whitish ochreous. 
Forewing whitish ochreous, at the base black scales. An interior and an exterior row of black dots traceable; 
at the cell-end a faded spot. Hindwing brownish-white. 35 mm. Natal. 
P. brunneifascia Hmps. is coloured as flavida, but with a dark reddish-brown radial band from near 
the base almost to the distal margin below vein 5. Traces of a faded band from the centre of the cell to the apex. 
A row of brown marginal dots, Hindwing white. 30 mm. Congo. 
P. nigrovittata Aur. (72 b). White, abdomen somewhat brownish. In the forewing a blackish radial 
band from the base almost to the margin below vein 5. Hindwing pure white. 25—30 mm. West, South, 
East x4frica. 
P. minima Hmps. Very similar, smaller. Thorax brownish, abdomen orange. Forewing white, finely 
dusted with brown. Hindwing silken white. 20 mm. Niger District. The type is presumably aberrative. I saw 
a specimen from the British Museum with a black band as in nigrovittata, though somewhat shorter.
