ceous. Under surface pale sandy brownish : wings with grey discocellular lunules followed 

 by two grey lines, the first indistinct nearly central, the second better defined, subangulated, 

 dentate-sinuate, followed upon the primaries by a stramineous belt which does not extend 

 above the upper radial vein; beyond this band the wing is grey-brown to the margin: 

 secondaries with a zigzag grey submarginal line; a large apical patch and the fringe brown ; 

 palpi crossed by grey lines. Expanse of wings 53 millim.

Testaceous : wings crossed by seven or eight badly defined zigzag greyish lines ; a pale 

 yellowish line crosses the wings in a straight line from about the apical fourth of the costa of 

 primaries to beyond the middle of the abdominal margin of secondaries ; this line is edged 

 externally with a line of deep rufous-brown and a band of paler rufous-brown, which is 

 bounded again by one of the zigzag lines ; a submarginal series of blackish points, between 

 which are marginal points arranged in pairs. Under surface stramineous : the primaries 

 darker than the secondaries; orbicular spots represented by blackish dots; rcniform spots 

 represented by blackish annular markings ; two subparallel blackish zigzag lines beyond the 

 cell, the first of which lines on the primaries stops short at the discocellular spot ; a series of 

 blackish dots across the disk ; submarginal and marginal series as above ; pectus pearl-white. 

 the legs pale sandy yellowish, barred with grey. Expanse of wings -45 millim.

Snow-white : primaries above with the basal half crossed by two separated, oblique, 

 parallel, black stripes ; a slightly oblique smoky-brown stripe from the costa to the external 

 angle ; an abbreviated submarginal black line ; costal margin dotted with black ; fringe 

 brownish at the base : secondaries traversed by an elbowed black line parallel to the abdominal 

 margin; a large, oblique, pyramidal discal patch from just above the first subcostal branch to 

 near the outer margin, ochreous with smoky brown extremities, its base excavated ; subapical 

 area striated with brown ; a marginal, black, sinuated line connecting the caudal denticles ;
