Alhed to 7. dimissa, Walker, xxii. 516, but much smaller ; 
can easily be distinguished by the difference in the markings 
below, the latter having a nearly straight black band from 
the abdominal margin ot hind wings a little beyond the middle 
to the costa of fore wings near the apex; the submarginal 
band of dimissa also is very differently situated and does not 
extend up the fore wings.
