Dark purplish-brown, glossed with violet-blue in some aspects : forewing with a 

 transverse basal, subbasal, medial, discal, and submarginal pale-bordered black 

 sinuous lines, the discal line running close to the medial from the base and then 

 irregularly curving outward beyond the end of the cell ; a black orbicular spot, and 

 a pale centred oval reniform mark ; a marginal row of small pale spots : hindwing 

 with a transverse waved discal pale-bordered black sinuous line, and a submarginal 

 lunular line, and a marginal .row of pale spots. Thorax with dark bands, abdomen

Wings large, woolly at the base : forewing very broad, triangular, costa much 

 arched towards the end, apex pointed, exterior and posterior margin being of about 

 equal length, the former deeply scalloped ; cell short, less than one-third the length ; 

 first subcostal emitted at one-half before end of the cell, second at one-fifth, trifid, 

 third at a short distance from base of second, and fourth at one-half from base of 

 third, fifth from end of the cell and slightly touching third close to its base; 

 discocellular inwardly oblique, bent in the middle and close to each end, radials from 

 the angles ; middle median at one-fourth before end of the cell, lower at more than 

 one-half ; submedian straight, with a short slender spur from below the base : 

 hindwing in male with the costal border broadly folded over on to the upperside 

 from base to near end of upper median ; beneath the fold is a glandular patch of 

 densely packed, extremely fine and delicate long silky filaments ; exterior margin 

 broadly scalloped ; cell short, reaching only one-fourth the length, the upper end 

 abbreviated to half its length ; costal and subcostals very short, ascending to the 

 border of the fold before the middle, the subcostals being wide apart at their base, 

 and each ending in a slender thread on the extreme costal edge ; discocellular very 

 oblique, bent acutely inward near upper end, the radial from below the angle ; two 

 upper medians from end of the cell, lower at one-third ; submedian and internal vein
