Fore wing with median area between costal margin and 
M? mostly of the ground-colour, the reddish line before the 
subterminal brightened (bay, slightly inclining towards 
maroon), thickened into a band, running from hind margin 
to R?, then out along R? (—R?) to termen. 
Find wing with the reddish subterminal spot between the

markings near base—namely, a short irregular line or streak 
behind SC and some maculation about the fovea; the usual 
Dysphania markings faint, indicated in darker colour; basal 
streak apparently slight, the succeeding angulated band little 
interrupted, formed more as in subrepleta than in militaris ; 
discal spot rather more conspicuous, elongate outward, its 
distal side tapering ; submarginal white spots small, that 
between SC° and R? cut by a thick purple line along R’, 
those between R? and M! more distally placed, the posterior 
one the smaller, a quite small spot between M! and M?, the 
rest obsolete,
