Anterior wings with a large, somewhat hatchet-shaped pitchy-black blotch 

 reaching beyond the middle of the costa and extending almost to the inner 

 edge of the wing; beyond which is a whitish space, shaded off towards the 

 hinder margin to brownish, and bearing a slightly curved row of ocellated 

 spots, having a dusky pupil and whitish margin ; on the hinder margin is an

 Bentley, to whom I am indebted for my specimens, found it in plenty 

 between Spitchwcck and Buckland in Devonshire.
