Much paler in the ground-color of the forewing than the typical form, the olive-gray shades being replaced by whitish; this is particularly evident between the reniform and apex of wing and along the inner margin. The broad blackish shading through central portion of wing from base to outer margin is heavy and a similar shade patch occurs on costa above the orbicular and reniform; the former is filled with white and in consequence is quite a prominent feature of the maculation, the latter is also largely white-filled with a slight ochreous shade in central portion and a strong black border-line on basal side. Secondaries almost pure white with faint traces of smoky terminal shading (somewhat more pronounced in the female) and indications of a smoky postmedian line in costal half of wing. Expanse 35 mm.
