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 ; reniform spots 
represented by blackish annular markings ; two subparallel blackish zigzag lines beyond the 
cell, the first of which lines on the primaries stojis 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 millira,

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