Thorax pale ochreous. Forewing ground colour whitish, costa suffused brown in basal half; a broad yellow arc from dorsum before middle towards tornus enclosing a silver grey dorsal wedge; an elongate dark fuscous discal spot, yellow costal strigulae beyond, outwardly edged with brown suffusion; termen yellow with broken black subterminal and terminal lines; a pale silver grey tornal spot; terminal cilia pale fuscous. Hindwing base whitish with a diffuse brown spot; a broad yellow central band, outwardly suffused brown; four black eyespots each with a silver dash on the inner side; a silver grey tornal spot before yellow apex; cilia pale fuscous but blackish adjacent to eye-spots.
Male genitalia (Fig. 111): Uncus digitate; gnathos 4/5 length of uncus, tapered with small thorns near apex; valva simple, widest at about ¾ of its length, two specialised setae arising near apex, one broad and flat about half length of valva, the other narrow and about one third length of valva; aedeagus cylindrical, sclerotised ridges towards tip. Sternum 8 with a sclerotised plate which is gently emarginate centrally.
Female genitalia (Fig. 163): Ostium small, antrum narrow to a sclerotised colliculum; ductus long gradually widening into ovate corpus of about the same length, signa comprising a pair of small sclerotised ridges near ductus and a pair of long broad spiculate patches along most of length of corpus bursae.
