 from costa to median vein containing orange spot in upper half of 

 cell (sometimes in lower half also) and a smaller spot on sub-median 

 fold ; a black streak along sub-median fold, a basal orange sjiot and 

 two sub-basal above and below cell ; an antemedial series of spots 

 incurved from vein 1 to below cell where it is angled, then oblique 

 to costa ; a postmedial series incurved from inner-margin to vein 3, 

 then excurved to costa ; a sub-terminal series bent outwards at vein 

 7 ; a terminal series on the veins. Hind-wings whitish heavily 

 suffused with fuscous, veins fuscous ; minute orange spots at ends 

 of veins, the amount of suffusion very variable, often almost
