connected in middle by a horizontal branch with preceding band; this 
fascia also connected by an irrorated branch above middle with apex, on 
costa forming a well-defined elongate dark fuscous spot ; this spot preceded 
by another similar spot and followed by a larger quadrate spot in apex; 
these costal marks separated by pairs of ill-defined whitish transverse 
strigidae; lower half of termen and tornus with a narrow marginal suffused 
brown line. Cilia light greenish, with a darker greenish antemcdian shade, 
and a paler basal line. Hind wing with veins 6 and 7 soldered towards 
base; rather dark bronze-greyish , cilia concolorous, paler towards tips. 
Uncus with upper edge incised ventrally. Socius with pointed top. 
Gnathos strong, an X-shaped body with broad lower and curved upper 
projections. Valva rather narrow, sinuate, constricted beyond middle; 
cucullus transversely dilated, with three marginal dentations below; 
sacculus under 1 / 2 , apical projection moderate, triangular (Slide No. 781 I), 
holotype).

9 16 mm. Head, scape of antenna and palpus pale yellowish-whitish, the 
latter with basal segment and anterior half of median segment irrorated 
with brown, terminal segment greyish; flagellum of antenna dark fuscous. 
Thorax whitish suffused with very pale ochreous-brownish. Abdomen 
ochreous-whitish, touched with pink anteriorly, posterior halves of seg- 
ments suffused with grey above, anal segment grey. Legs pale ochreous, 
anterior tibia and tarsus dark fuscous, pale ringed. Fore wing elongate- 
subovate, rather pointed, costa gradually gently curved throughout, 
apex subacute, termen moderately sinuate, oblique. Ochreous-whitish, 
base suffused with olive-greenish, middle of wing suffused with greenish- 
grey touched with bluish, disc before termen suffused with pale fulvous; 
markings dark brown tinged olive. Anterior half of costa narrowly suffused 
with greenish-grey, becoming darker anteriorly, with some two small dark 
brown marks beyond base; a rounded dot above dorsum beyond base; 
indication of an outwardly convex transverse fascia at 1 / 4 , formed by a 
small mark on costa, bifid below, by some irroration and a greenish-grey 
suffusion in disc and by a conspicuous triangular, slightly inwardly 
oblique dark brown spot on dorsum beyond 1 / 4 , reaching to fold; another 
such spot on dorsum before tornus with anterior edge inwardly oblique, 
posterior edge vertical; a moderate dark brown subquadrate mark on 
costa before middle, produced below into a thick excurved longitudinal 
patch in disc below costa not reaching 2 / 3 of wing, dark brown, suffused 
with deep olive posteriorly, with upper edge excavate; a less distinct 
smaller invert elongate-triangular spot in fold below preceding patch,
