Three rather short fine lines are found towards the hindmargin, between the last two streaks and there is a slender line from three-fourths of the disc to the costa, before the apex and a similar but shorter streak beneath to the apex, as well as some obscure whitish scales along the inner margin indicating an unexpressed streak.
