There is a dark fuscous dot above the dorsum at one-third and an oblique dark fuscous mark from the dorsum at two-thirds, both sometimes almost obsolete. Four longitudinal dark fuscous lines are found on the posterior half of the wing, the first and third converging to near the apex, the second terminating at three-fourths, the fourth running to the tornus, between the third and fourth, there is an acutely inwards angulated line running from the termen to three-fourths and back to the termen.
