palpi short, filiform, ascending. Forewings with tufts of scales ; 
4 and 5 nearly approximated on basal third, 7 and 8 out of 9, 
10 and 11 approximated. Hindwings 4 and 5 nearly approximated

irrorated black, in the other the shades hardly brownish and median 
space similar to rest of wing, first line at direct, slightly bisinuate, 
second from costa at | to dorsum near torn us, median third abruptly 
excurved, waved ; discal spot partially dark-marked ; terminal area 
somewhat darker brownish ; an interrupted fuscous terminal line :
