the tibia; mid tibia with two terminal spurs, covered with scales and ending 
in a curved point which has teeth on the inner side; outer spur about Jth 
shorter than inner spur ; hind tibia with four spurs, in structure and proportion 
like spurs of mid tibia; a tuft of scales on mid and hind tibiae at frd of their 
length. 
Fore wing rather narrow; costa gently curved till vein 12, where it has a 
bulge outwardly, then almost straight to apex, which is rounded ; termen very 
oblique, well curved between veins 2 and 7 and somewhat sinuate up till 1 b ; 
tornus very acute; inner margin incurved beyond tornus, then outcurved at 
|rd; 1 b well curved (like inner margin), indistinctly forked; lower median 
upcurved; 2 from frd lower median; 3 from fth 2 to 4; 4 from lower angle; 
5 from middle of discocellulars which are erect; 10 from upper median from 
before upper angle at about half the distance of vein 5 to upper angle, then 
anastomosing with 6, 7, 8, 9 to form an areole as long as nearly half of 10; 
-6 from areole at frd; 7 stalked with stalk of 8, 9 for half length of 7; 9 from 
8 at fth of 8; 10 from stalk of 7, 8, 9 well beyond the areole; 11 from upper 
median at frd; 12 parallel to costa, ending at frd of costa. Hind wing sub- 
triangular; costa slightly arched; apex obliquely rounded; outer margin well 
curved, sinuate; tornus rounded; inner margin incurved; 1 a and 1 b somewhat 
incurved; 2 from before frd lower median; 3 from fth of 2 to 4; 4 from lower 
angle ; 5 from middle of discocellulars which are erect and have indications of 
a forked vein in the cell ; 6 and 7 stalked for frd of 6 ; 8 upcurved at base, down- 
curved at frd then obliquely upcurved to near apex ; upper median well curved 
and connected to 8 by a bar at before half its length. The hind wing of all 
species coming in this genus have all, as far as I know, a dark mark at the 
tornus, intersected by one or more light striae. Of the other South African 
Notodontids only bicolor has an indication of such a spot, but that it does not 
come in this genus at all is clearly shown by its structure, as it has vein 7 of 
fore wing from before the free part of vein 10 and not as in Chadisra ; moreover 
the broader fore wing, the heavier build and the very long pectination of the £ 
antennae place it at once in Antheua. I therefore take it out of Chadisra, 
leaving only 4 species, which may be distinguished as follows : 
1 a. Antennae of A bipectinate, with long branches ..... 2 
b . Antennae of A minutely serrate and fasciculate ..... 4 
2 a. Apex of antennae ciliated ......... 3 
b. Apex with short branches, colour of fore wing uniform rosinaria 
3 a. Colour of basal part of fore wing yellow, terminal half rufous mixed 
with grey ........ semiflava 
b. Whole fore wing uniformly ochreous, suffused with red-brown and 
slightly irrorated with black ..... uncifera 
4 a. Basal half of fore wing pale yellow, irrorated and in parts clouded 
with brown ....... persimilis 
b. Basal half of fore wing pinkish ochreous-grey, in some specimens 
lighter, in others darker than the terminal half, but never pale 
yellow ......... curvilinea 
Chadtsra Curvilinea.

Hyperaeschra curvilinea Swinh. A.M.N.H. 7. xix. p. 207 (1907). 
This species evidently does not come in Hyperaeschra, a genus so far not 
recorded from S. Africa for other species, as the inner margin of the fore wing 
has no tuft of scales, the palpi have scales as well as hairs, and 6 of fore wing
