g 11 mm. Head white. Antenna pale fuscous, finely ringed with darker 
fuscous, scape whitish. Palpus white, median segment suffused with 
fuscous laterally, terminal segment with a broad median fuscous band. 
Thorax (damaged) fuscous mixed with white. Abdomen fuscous above, 
whitish-fuscous helow, a series of lateral oblique fiscous lines, anal tuft 
glossy fuscous-whitish. Legs whitish, anterior femur, tibia and tarsus 
fuscous-black above, median and posterior legs with broad fuscous- 
blackish median bands on tibiae and all tarsal segments and a subapical 
band on tibiae, posterior spurs with blackish tips. Fore wing elongate-ovate, 
rather narrow, costa hardly curved anteriorly, slightly impressed in middle, 
apex and termen rounded, no anal angle. White, markings suffused with 
fuscous. A dark fuscous elongate spot on base of costa indistinctly con- 
nected along base of wing with a dot on base of dorsum; four-fifths of the 
costal half of wing rather suffused with pale fuscous, except for costal 
markings of pure white ground colour arranged as billows: an outwardly 
oblique wedge-shaped mark at 1 / 3 reaching to middle of disc, edged anteri- 
orly by a narrow fuscous outwardly bluntly angulate transverse fascia 
which is moderately extended along costa anteriorly, becomes faint below 
and hardly reaches 1 / 4 of dorsum, posterior edge of this costal white spot 
formed by a short transverse fuscous mark; a smaller, less oblique white 
wedge-shaped mark slightly before a / 3 of costa, followed by an elongate- 
ovate, slightly subcostal white dot somewhat before 3 / 4 , both surrounded 
and connected by dark fuscous suffusion; an oblique well-defined daik 
fuscous band occupying posterior sixth of costa and apex, edge outwardly 
oblique, apical extremity rounded; this band contains a small invert- 
wedge-shaped white mark just below '/r, costa and a large elongate- 
triangular white dot traversing band below its middle, with acute top 
directed basad ; posterior third of disc below these markings white, hardly 
infuscated, except for an ill-defined transverse suffusion on 3 / 4 of dorsum 
and a fuscous irregular marginal streak in tornus, both connected posteri- 
orly with fuscous costal markings. Cilia white, dark fuscous are a narrow 
subbasal line running throughout, and a broader apical line from costa to 
opposite termen below apex of wing; dorsal cilia long, glossy light, bronze- 
fuscous. posteriorly with apical part suffused with whitish. Hind wing 
rather light fuscous, cilia glossy bronze-fuscous. 
Tegumen pointed. Anus moderate. Valva elongate, little dilated, 
bristled along proximal and apical edges on the inner side; pads at base 
of costa moderate, weakly bristled; sacculus 1 / 2 , entirely separate, subovate, 
obtusely pointed, naked. Vinculum, a strong semicircular band; a small
