Forewing greyish-brown and red-brown, particularly in the apical area. Two oblique interior lines, the first 
outside white, distally curved at the median vein. The second inside white, excurved below the costal margin. 
An ochreous brown streak on the cross-vein and a similar line to the inner margin, behind it darker. Exterior 
line pale, oblique from the costal margin to below vein 2 , behind it darker, and black marginal dots. Hindwing 
reddish-brown. 30 mm. Natal. 
P. albifasciata Hmps. Thorax and abdomen brownish white. Forewing pale reddish-brown. A triangular albifascia- 
white radial band on the median vein to the cell-end, where it is broader. One white spot each between veins 
3 , 4 and 6 , 7. Veins whitish. 30 mm. Sierra Leone. 
P. roseitincta Jcmse (68 i). Thorax and forewing brownish-pink, abdomen lighter. Marking white, roseitincta. 
Basal and interior lines excurved at the inner margin. Exterior line almost straight, parallel to the distal margin, 
close behind the round white reniform macula which is indistinct in the $. Median line from the reniform macula 
to the inner margin close at the exterior line. Before the margin a black line. Hindwing pale orange brownish, lucida. 
Transvaal. — lucida Aur. has white hindwings. East Africa. 32—34 mm. 
P. voeltzkowi Aur. (68 i) is separated from the preceding species by the absence of the white reniform voeltzkowi. 
macula also in the $ and of the black submarginal line. Hindwing pale yellow. 26 mm. East Africa. 
P. violacearia Janse (69 a), d similar to roseitincta. Forewing more reddish. Interior line so strongly violacearia. 
excurved at the inner margin that it touches the exterior line. Abdomen and hindwing darker. $ quite different. 
Fore wing brownish-red, the lines as in the d- The round reniform macula is violettish-black, obliquely continued 
inwards to the base of vein 2 . From there a triangular stripe to the end of the submarginal line and along the 
latter broadly upwards almost to the costal margin. In a subform of the $ the lines and the reniform macula 
are absent. 33—42 mm. Transvaal, Natal. 
P. ferrughiea Hmps. Body yellowish rust-brown. Forewing rusty red, at the inner margin lilac grey, ferruginea. 
Discoidal spot with a light streak. Below it and before the distal margin likewise lilac grey. Hindwing pale 
rusty red. 35 mm. Rhodesia. Entirely separated from the other species by the broad forewing and the different 
scheme of markings. 
All the following genera exhibit hairless eyes. 
I. Ptilura-Group. 
The species exhibit glossy spots on the forewings. 
4. Genus: Ptilura Holl. 
Palpi moderately long, porrect, proboscis absent. Antennae as far as % of their length strongly 
pectinate, abdomen long, hind tibiae with 1 pair of spurs. Forewing broad. Veins 3 and 4 distantly separated, 
6 and 7 from the cell-angle, 10 -f- 8 -f- 9 stalked, 7 and 10 forming the differently long accessory cell by a bar. 
In the hindwing veins 6 + 7 on a short stalk, 8 close by the cell almost to the end. 
P. argvraspis Holl. (69 a). Thorax and forewing blackish-brown, abdomen and hindwing little lighter, argyraspis. 
Fore wing with lustrous green spots. A large one each above veins 1 and 3, smaller ones below vein 2 and before 
the distal margin. 42—46 mm. Cameroon, Lowa (Congo). 
5. Genus: Argyrothyris Bryl. 
Palpi somewhat longer, proboscis absent. Antennae of $ finely ciliated, abdomen long, hind tibiae 
with 2 pair of spurs. Forewing broad, anal angle angular. Veins 3 and 4 close together, 6 —(- 7 —|— 8 + 9 —R 10 
stalked. In the hindwing veins 3 j- 4 on a short stalk, 6 + 7 on a long one, 8 parallel to the strongly curved cell. 
A. allocota Bryl (69 a). Thorax and forewing brown, in the centre darker with silvery spots. A large allocota. 
triangular spot in the cell-end, 2 small ones obliquely behind it, and 2 near the apex. Hindwing and abdomen 
dark brown. 25 mm. Cameroon. 
A. privata sp. n. (69 a). Thorax and forewing brown. On the forewing a violettish-brown streak from vrivata. 
the base to the distal margin above vein 4. The median vein at the end, the space between veins 2 and 4 
and behind the centre of the inner margin darker red-brown. At the angles of the cross-vein 2 fine white dots. 
A submarginal row of white dots, in which the dot above vein 4 is larger and more distally situate. Also at 
the margin fine white dots. Hindwing somewhat less dark brown. 28 mm. Congo. Type: 1 d in the Berlin
