Labial palpi white. Face, head, and thorax white. Forewing dark 

 purplish fuscous, overlaid with and irrorated with lighter, slightly raised,

 of costal edge within this white space is dark fuscous; at apical third is 

 a large, irregular, poorly defined white costal blotch, reaching down to 

 [the end of the cell ; connecting these two white areas is a longitudinzJ 

 fthin black line in the cell; in the apical portion of the wing is a Icirge 

 'ill-defined area strongly mottled with black; cilia dark fuscous with white 

 pasal line. Hindwing on both sides and underside of the forewing light
