Forewing yellow mixed with fuscous scales; base covered with yellow scales, base 1/3 and 2/3 of costa with a black spot respectively; antemedial line black, indistinct; two black spots located at basal and terminal of cell, respectively. Central area suffused with pale yellow mixed brown; an androconium presents on the discocellular; postmedial line thin, waved, black with yellow edges, outer area covered with yellow scales; cilia mixed with yellow and fuscous. Hindwing paler than forewing and more or less reddish, postmedial line waved. Female. Similar with male, but forewing with less fuscous scales and androconium absent, hindwing redder.
