<$. Proboscis very short ; palpi a little beyond Irons, moderately 
hairy, slightly ascending; first joint rather large; second joint less than 
2 times first joint ; third joint less than \ first joint and a little hairy 
above ; eyes rather large, almost width ol frons, round ; frons rounded 
and with short thick hair ; antennae short, less than J of costa, bipectinate, 
curved downwards and at tip again upwards ; branches about 6 times 
shaft, getting suddenly shorter at apex, ending each m 2 long bristles, 
except last :J, which ends in 1 long and 1 very short bristle ; basal joint 
of shaft with a long thick tuft of hairs ; in $ the branches are shorter, 
especially beyond f, and all branches have 1 long and 1 short bristle. 
Thorax and abdomen with very thick hair ; no distinct crests ; legs 
very hairy on femora and tibiae, especially the hind legs ; fore tibia with 
the process nearly as long as the tibia, not flat (as is the case in all other 
Lymantriadae I have studied), but peculiarly twisted, especially towards 
the outside ; mid and hind tibiae with 2 spurs only. 
Fore wing semicircular ; costa straight ; termen and inner margin 
well rounded ; termen somewhat crenulate ; apex and tornus much 
rounded ; lb much curved ; 2 from § of lower median ; 3 from beyond 
distance 2 to 4 ; 4 from lower angle ; 5 from near lower angle ; cell 
over \ of wing ; discocellular distinct, angled at middle ; 6 from upper 
angle ; stalk of 7, 8, 9 from near upper angle ; 7 from beyond \ stalk 
of 8 and 9 ; 9 from ^ free part of 8 ; 10 from upper median beyond J dis- 
tance of 11 to stalk of 7, 8, 9, and parallel to this stalk ; 11 from f upper 
median, parallel to 10 ; 12 very near to costa. 
Hind wing sub-triangular ; costa and termen rounded ; inner margin 
straight ; termen somewhat crenulate ; apex and tornus much rounded ; 
la long ; 16 curved ; 2 from § lower median ; 3 from beyond f distance 
2 to 4 ; 4 from lower angle ; 5 from a little above the angle ; cell over 
J of wing ; discocellular somewhat oblique, angled at beyond \ ; 6 and 7 
trom upper angle ; 8 much curved to beyond J upper median, which it 
touches for some distance, but without a bar, then it becomes parallel to 7. 
Only one species is known in this genus, distributed all over Africa. 
1 have seen specimens from : — 
Noordkaap (I, Janse). 
Glroenvlei (I, Janse). 
Barberton (I, Janse). 
White Biver (II, Cooke), 
Durban (VIII, Leigh). 
Port St. Johns (II, Swinny). 
This species I only found in places with dense vegetation, where it 
rests exposed on the upper side of leaves, with the wings only partly 
closed. In that position it resembles a white feather very much.
