 fuscous. At the end of the cell is a small blackish dot, followed by a trans- 

 verse, elongate triangular, dark fuscous shade ; between this and the dark 

 apical part of the wing is a nearly unmottled, narrow fasci-form, ochreous 

 white space, limiting sharply the dark apical part, which is darkest towards 

 the base of the wing and gradually becomes lighter towards the tip. Upper 

 side of the hind wings light whitish fuscous with the ornamentation of the under
