Hmpsn., Ann. S.A. Mus., p. 405 (1905). 
This species is not an Aclonophlebia as Hampson states, l.c. p. 405, 
as it has 4 spurs on the hind legs and not 2 as is the case in Aclono- 
phlebia .

<J. Proboscis absent ; palpi short, not quite reaching frons, drooping 
a little ; first joint a little longer than thick, with long hair on under side ; 
second joint 1| times first joint, with long hair on under side pointing 
forward ; third joint as long as first, with some hair and somewhat hidden 
in the hair of the second joint ; eyes large, elliptical, about width of frons ; 
frons rounded, covered with woolly hair ; vertex with long hair ; antennse 
i of costa, bipectinate ; shaft much curved ; pecten about 8 times shaft, 
m $ about 4 times ; pecten ciliated and ending in a long bristle ; thorax 
clothed with long hair ; abdomen a little longer than hind wing, covered 
with woolly hair and a moderate tult of spreading hair at first segment ; 
tibiae with very long hair ; fore leg with tibia in both sexes with 
a process, which in the A is about as long as the tibia, thick and with long 
hair on outer side, in $ thinner and apparently with a short second joint, 
also covered with long hair ; mid and hind tibiae each with 2 terminal 
spurs only. 
Fore wing triangular ; costa, inner and outer margin nearly straight ; 
apex and tornus well rounded ; lb simple at base ; 2 from beyond J lower 
median ; 3 from a little farther from 4 than 4 is from 5 ; 4 from lower 
angle ; 5 from a little above angle ; discocellular very oblique and hollowed 
at middle ; cell over J of wing ; 6 from a little below upper angle ; stalk 
of 7, 8, 9, 10 from upper angle ; 7 from before J of 9 ; 8 from £ of 9 ; 
10 from \ of stalk 7, 8, 9 ; 10 a little curved and for some distance parallel 
to stalk 7, 8, 9 ; 11 from of upper median, nearly straight ; 12 nearly 
parallel to costa. 
Hind wing triangular ; costa and inner margin nearly straight ; ‘outer 
margin well curved from vein 16 till 7 ; apex and tornus well rounded ; 
la long, straight ; 16 a little curved ; 1c faintly indicated ; 2 from § lower 
median ; 3 and 4 from close to lower angle ; 5 from well above the angle 
(about 3 times the distance of 3 to 4) ; discocellular very oblique, directed 
inward, angled beyond | ; cell a little over J oi wing ; 6 from below upper 
angle ; 7 from angle ; 8 curved towards upper median at beyond J, where 
also upper median is angled, and just touching it, then parallel to costa. 
Hampson, l.c. p. 410, treats this genus as a synonym of Lymantria , 
but 1 think it is sufficiently distinct to keep it separate. The process of 
the fore leg is much as in Dasychira and the palpi are quite different ; 12
