c? ? . Easily distinguishable from the otlier sjiecics of southern Brazil by the 

 reddish colour of the hiudwing and the brown abdt)minal area which extends to the 

 base. On the underside of the forewing there is a large postdiscal patch between 

 costal naargiu and li" of an ochraceous clay colour, including proximally a sharply 

 marked brown line, besides traces of another line ; tliis j)atch is separated from a 

 posterior discal patch of the same colour ; black submarginal line bordering the 



greyish brown marginal band straight from W to iiinder margin. Hiudwing 



dirty rufous-ociiraceous, except margins, three discal lines and a stigma.

 and SO'', the posterior discal patch also redxiced, the brown lunulated lines within it 

 heavy ; greyish brown borders of hiudwing broader than in tlie preceding, the 

 chestnut-tawny area consequently more reduced, not reaching distally to 0, as it does
