middle; edge of basal patch slightly concave above and below fold; patch 
suffused with tawny, less so towards base, less suffused in male, along 
costa with a row of dark brown dots; these dots more or less continued 
across wing by brown transverse lines parallel to upper edge of basal patch ; 
this edge suffused with brown , much broader along subplical part; dorsal 
half of patch coarsely transversely strigulated with dark brown, slightly 
suffused with greyish ; a conspicuous patch of white ground colour (less

this dotting; ground colour elsewhere suffused with leaden-grey, becoming 
darker and more glossy posteriorly; posterior half of costa black, with a 
row of five pairs of white transverse marks, becoming thicker and more

subtriangular large blotch before termen from below costa to above 
tornus : tawny, in male suffused w ith black except in middle ; upper anterior

an inwardly oblique blackish streak from above middle of blotch running 
to the top of preceding discal spot; this blackish streak often extended 
(and then conspicuous), slightly curved, running from lower angle of cell 
to just before apex; a small spot in apex with a streak along upper 2 / 3 of 
termen and some two small transverse marks in tornus: blackish, latter 
reaching lower edge of preterminal blotch; apical edge below and terminal 
edge between markings narrowly white ; a vertical streak of glossy leaden- 
grey ground colour before termen, traversed in middle and below apex by 
a minute black horizontal line; in male markings much obscured by an 
ill-defined blackish-grey suffusion on upper half of wing beyond its middle;
