^. 26 mm. Face blackisli grey ; palpus blackish grey, the joints 
tipped with whitish ; pectus and coxae varied with blackish-grey 
and whitish, forefemur blackish-grey anteriorly, foretibia and tarsus 
blackish with whitish rings, midtibia and tarsus the same, but pale 
on their inner side, hindleg pale. Ground colour of wings white, 
that of fore wing almost entirely covered by the blackish-grey mark¬ 
ings, which are without a trace of the green tinge so prevalent in 
species of this group. Forewing with dark basal patch, intermediate 
band and median band, the three almost joined into one dark area 
in one of the specimens (in the type, this part of the wing is much 
rubbed, but evidently the space between basal and median areas is 
somewhat lighter), the basal and median band.?, however, somewhat 
the darkest; median band occupying middle one-third of costa, and 
almost equally broad on inner margin, hence with its outer boundary 
here rather near tornus; its inner boundary somewhat concave, its 
outer indented on SC®, sending out a minute tooth anteriorly thereto, 
bilobed from R® to M-, and slightly oblique distad from to inner 
margin; a somewhat blacker cell-spot; a narrow w'hite band 
traversed by a weak dark line separates the median from terminal 
area, which is again dark, somewhat variegated with a rufous tinge 
and with deeper black, and containing the irregular, interrupted, 
pale subterminal line. Hindwing white, faintly shadowed with grey 
basally, a dark cell-spot rather near base (cell being short), a terminal 
black line from tornus nearly to fringe of this part of the wing 
blackish ; inner marginal fold moderately developed. Undersurface 
of forewing similarly marked to upper, but more’weakly ; of hind-
