 macular ; the spaces between the transverse markings are 

 freckled with blackish. Secondaries whitish, freckled with 

 grey before the blackish, wavy, central band, and ochreous 

 beyond it; submarginal band blackish, broken up into spots, 

 of which that nearest the middle is the largest. Fringes of 

 primaries blackish, chequered with white, and of secondaries 

 yellow, chequered with black, preceded on all the wings by a 

 row of blackish spots. Under surface of primaries have the 

 markings of the upperside indicated, and on the secondaries 

 the markings are reproduced, but the outer half of the wing

In one male the markings on primaries are brownish, but

 brownish border intersected by a transverse wavy white line.

 broad black band, which is intersected by the venation and 

 outwardly edged with whitish. Secondaries yellow ; basal 

 area fuliginous grey; there are three rows of black spots, 

 those forming the first row being more or less confluent, but
