in middle and before posterior end with ground colour, mixed below with 
orange, connected with anterior branch of a strong, Y-shaped discal mark, 
reaching to vein lb, mixed and interrupted above middle by orange 
scales ; space between this and preceding transverse mark almost entirely 
tilled with slightly raised lilac-fulvous scales from costa to fold; posterior 
arm of Y-shaped streak connected above with a transverse curved patch, 
encircling posterior edge of cell, mixed below with orange, and connected 
with an erect-rectangular patch on dorsum just before tornus that extends 
to below vein 4 ; the last mentioned patch orange, edged with black, which 
colour merges above posteriorly in an invert-U-shaped black mark on 
termen above tornus; curve of the U thickened, centred with orange, arms 
arising from terminations of veins 2 and 3, respectively, top continued 
by a broad black blotch to vein 7 ; a small black U-shaped mark above 
vein lb at 3 / s ; a semiovate dot on 2 / 3 of costa, followed by a rounded- 
triangular moderate costal patch reaching to below vein 8, with a small 
costal dot of ground colour in its middle, traversed by an orange streak 
along vein 10, which reaches anteriorly to cell; termen with black dots on 
terminations of veins, apex slightly mixed with orange. Cilia white 
(damaged), basal half with black bars. Hind wing white, touched with 
greyish-fuscous, faintly marbled and transversely strigulated with dark 
grey posteriorly, cilia whitish, a faint row of small greyish antemedian dots. 
Tegumen and uncus strongly sclerotized, latter curved, rather short, 
top strongly dilated, emarginate, short-bristled. Socius moderate, marginal. 
Gnathos rather short, arms curved, narrow, dilated towards top, connected 
with each other by a narrow membraneous ridge. Transtilla strong, broad, 
triangular. Valva ovate, costa thickened posteriorly, densely haired. 
Sacculus under x / 2 , convex ; harpe, an oblique brush of bristles. Aedoeagus 
pistol-shaped, orifice obliquely truncate. Cornuti, a double row of short 
teeth. (Slide No. 740 D., holotype). 
$ 22.5 mm. Head pale sulphur-yellow. Antenna black, scape pale 
sulphur-yellow. Palpus rather long, slender, black, terminal segment 
whitish. Thorax black, slightly suffused with deep brown posteriorly, 
mixed with sparse pale yellow scales in middle and posteriorly, posterior 
edge, except apex and tegula, pale sulphur-yellow. Abdomen light brown. 
Legs whitish, anterior and median legs densely suffused with blackish, 
posterior leg with knee and a band at base of tarsus black. Fore wing 
elongate-subovate, dilated; costa little curved towards extremities, straight 
in middle; apex subacute, termen almost straight, hardly convex in 
middle, oblique. Pale sulphur-yellow, markings black, slightly mixed along 
edge with orange-fulvous. Base of costal edge black, a wedge-shaped, 
oblique spot with truncate top on base of costa reaching to below fold, 
and a small suffused elongate dot on dorsum below top of preceding; an 
oblique rather narrow transverse streak from 1 / 5 of costa, with anterior 
edge slightly concave, a narrow angulate projection from middle of 
posterior edge; this streak is bent on fold, lower part parallel to fold to
