The wingspan is about 32 mm. The forewings are yellow, the outer half with pale red-brown suffusion. There is a dark red-brown line from before the apex to the middle of the inner margin, meeting a vertical line which becomes obsolete at the median. There is also an irregularly wavy red-brown submarginal line, its upper half edged externally with silvery white. The hindwings are yellow, with an oblique antemedial line and a fine postmedial line. There is an oval silvery spot at the lower end of the discocellular, and a fine linear spot at the upper end.[3]
