There is a narrow subcostal streak from near the base to the middle, touching the costa on the anterior end and becoming attenuated posteriorly. Two very fine short streaks, somewhat obscure, are found between the posterior extremity of the subcostal streak and the costa at four-fifths, both touching the costa. There is also a broad, clear, longitudinal streak, from the base to just above the middle of the termen, the posterior half somewhat attenuated.

The hindwings are fuscous.McMillan, Ian (10 October 2010)
