tawny near middle, with three white spots near middle in a transverse

 tuft of white fringe at extreme tip of wing ; the posterior fringe jet 

 black, and about as long as width of the wing; hind wings uniform 

 blackish, with a long, deep black fringe ; the front margin of hind

On account of the short and basally thickened antennae, it 

 may form a new genus.
