   Female's have a black horizontal band on the outer edge and sub outer edge of the forewing, with the black horizontal band in the middle area interrupted.
   There are three large black spots and two small black spots in the middle cell, and two large black spots on the hind edge.
   The outer edge of the hind wing is black, with a black horizontal band on the outer edge and sub outer edge.
