touching posterior discal dot, narrowed towards costa and connected with 
a longitudinal small blackish patch along costa before apex, ending in 
apex; about five triangular suffused blackish terminal dots on veins, 
interconnected and narrowly produced anteriorly along veins, three lower 
dots confluent with preceding patch; a longitudinal dark grey streak 
occupying dorsum from beyond base to end of fold, with upper edge well- 
defined, slightly below fold, horizontal; a longitudinal grey suffusion along 
upper half of wing, from central third of costa to upper half of subterminal 
transverse patch, above with branches to costal markings, below indefinite, 
hardly reaching middle of disc dilated posteriorly, leaving well-defined 
white edges to three upper discal dots. Cilia whitish-grey, a dark grey 
median shade, darker towards apex; a whitish patch on basal half of cilia 
opposite apex. Hind wing with veins 3 and 4 stalked, vein 6 developed, 
but weak posteriorly; white or pale grey; cilia concolorous. 
Ostium small, dorsal wall with a blunt projection, at the top of which 
a small longitudinal impression with finely dentate edge. Limen, a rounded

patch of raised scales below fold at x / 5 , dorsum below this patch scattered 
with dark scales ; a light fulvous-fuscous suffusion along costa from before 
2 / 5 to s / 6 , reaching below 1 / 4 of wing breadth, with anterior edge well- 
defined, indent and vertical, posterior edge suffused; connected with 
greyish suffusion in centre of cell which is edged posteriorly by a transverse 
ridge of raised scales on closing vein, with anterior half fulvous -fuscous, 
posterior half white; about six dark fuscous, elongate, somewhat suffused 
costal dots, becoming less elongate and semicircular posteriorly, first of
