AV'ingi*, iip/ierside. Forewiiig ratlier broiidci' Miau in (junnascas, differuutly 



marked : ^ubba^al band brwad, almost extended to the very base of the wiug, 

 toucliiug tlie basal dot at HM-, tlie interspace between this dot and the baud and 

 nervure M scarcely larger than the dot itself; the band is preceded before JI 

 l)y a detached patch, wliieli stands a little more distal and is edged all round with 

 greyish white ; the patch does not reach the costal margin ; the grey scaling on 

 the disc mostly divided up into 3 to 5 series of narrow lunules ; discal s[iot 

 M' — ]\1- smaller than in gaimascus, subapical patcli much larger, being of the same 

 size as in euri/sthenes ; vein R' brown ; distal marginal area mucli more extended 



ulive-brown than in (/annascus. Hindwing also broader than in (latuiascus : 



median band 3i to 4 mm. broad, not obviously dentate upon tlie veins ; discal band 

 merged together with the postdiscal one, being se^iarated from it only in front; this 

 disco-postdiscal baud — resembling the letter Y — is not dentate, the veins not being 

 black as in the specimens oi gaimascus with broad bands ; the interspace between 

 tills band and the dark edge of the wing tawny olive, becoming rosy red at costal 

 margin. 



i 'lulerside. Forewing : the red colour of the basal area merges on the disc 



gradually into the brown or ochraceous colour of the outer area of the wing, while 

 ill (/rninascus the red area is more or less sharjily defined discally ; subbasal band 

 nearer the base than in ynnnascus, discal brown patch M' — M- small, grey outer 

 marginal area much wider than in gajinuscus, iucluding a brtuid burnt umber-brown 



band, Hindwing obviously shaded with grey, a discal and a postdiscal continuous 



line of red lunules, tlie outer one indistinct in S and followed by an ill-defined 

 grey line. 



S. Sexual armature as in qannascus, but tenth sternite less sinuate ; the 

 ]):it(h of modified scales on the clasper is brown, except the most dorsal portion, 

 wliicli is yellow.
