Apex of forewing acute, sometimes falcate; outer margin of forewing straight, that of hind wing forming a small acute protrusion at end of M1. Both wings yellowish white. Forewing with postmedial and submarginal lines forming two black patches on costa; antemedial line faint; medial line greyish brown, sometimes indistinct, forming an acute protrusion at M1; discal spot greyish brown, shortly linear; postmedial line appearing as a row of black spots, nearly parallel to medial line; a greyish brown band present outside postmedial line, extending from subapex, thin and indistinct above M1; submarginal line yellowish white, flanked by greyish brown and indistinct bands; terminal line indistinct, forming a series of black dots; fringes yellowish white. Hind wing with medial line greyish brown, almost straight; discal spot inconspicuous; postmedial line straight, present as a row of black spots, accompanied by a greyish brown band outside; submarginal line greyish brown, protruding outwards at M1, flanked by greyish brown bands, inner band often less distinct than outer one; terminal line similar to that of forewing. Underside pale yellow; transverse lines blackish brown, often similar to those of upperside, but discal spots and terminal lines of both wings more distinct than those of upperside. Forewing with R1 long stalked with R2, Sc connected with R1+2 by a short bar.

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

Male genitalia. Uncus short, rounded with a narrow digitiform process apically. Gnathos with median process vestigial. Valva deeply bifurcate; dorsal arm rod-like, bearing setae, a small rounded protrusion arising from middle of dorsal margin; ventral arm setose at terminal half, tapered and forming a curved spine apically. Saccus triangular, longer than length of uncus. Juxta short, almost oval. Aedeagus narrow posteriorly; vesica with two cornuti, both about two-fifths length of aedeagus, apical one stout and long spine-like, with tiny teeth on one side terminally, basal one very narrow.

Female genitalia. Lamella postvaginalis small, heart-shaped. Ductus bursae with an antrum, slightly narrow and curved posteriorly, sclerotized part about two-thirds length of ductus bursae. Corpus bursae oval, about three quarters length of ductus bursae; signum elliptic, with 15 to 18 marginal teeth. Seventh sternite of female abdomen sclerotized, with a semicircular cleft posteriorly.

Diagnosis. The diagnostic characters are given under the previous species.
