Apex of forewing slightly falcate; outer margin of forewing straight, that of hind wing with a small protrusion at end of M1. Both wings greyish white, mottled with greyish brown scales. Forewing with antemedial line indistinct; medial line greyish brown, forming an acute protrusion at M1; discal spot greyish brown, shortly linear; postmedial line narrow and indistinct, only distinct and thickened on each vein as black dots, protruding outwards at M1, then bent inwards; a greyish brown band present outside postmedial line, bent from subapex, often distinct and broader below M1; submarginal line greyish white, flanked by greyish brown and discontinuous bands; terminal line pale greyish, narrow and indistinct, with a series of small black spots inside; fringes greyish white. Hind wing with medial line greyish brown, straight; discal spot inconspicuous; postmedial line almost straight, similar to that of forewing; a greyish brown band present outside postmedial line; submarginal line greyish white, flanked by a distinct greyish brown band; terminal line and fringes similar to those of forewing. Underside transverse lines black; discal spots of both wings more distinct than those of upperside; submarginal line of forewing forming a black patch on costa. Forewing with R1 long stalked with R2, Sc connected with R1+2 by a short bar.

Abdomen. First abdominal segment greyish white, remaining segments pale greyish brown with black scales between each segment. Tuft of scales present on male sternite III.

Male genitalia. Uncus short, rounded with a short apical process. Gnathos with median process vestigial. Valva deeply bifurcate, bearing setae; dorsal arm rod-like, slightly protruding at middle of dorsal margin; ventral arm tapered and forming a curved spine terminally. Saccus rounded terminally, shorter than length of uncus. Juxta short, slightly protruding at middle of posterior margin. Aedeagus narrow posteriorly; vesica with two cornuti, apical one stout spine-like, more than one-third length of aedeagus; basal one short rod-like, rounded with tiny spines distally.

Female genitalia. Lamella postvaginalis small and semicircular. Ductus bursae with an antrum, slightly protruding outwards at middle, sclerotized at posterior half. Corpus bursae large and oval, about one-half length of ductus bursae; signum elliptic, with 15 to 16 marginal teeth. Seventh sternite sclerotized and shallowly concave posteriorly.

Diagnosis. The diagnostic characters are given under B. obliquata .
