Stigma blackish, hardly three times as long as its breadth ; 
recurrent nervure sensibly rejected ; 2nd discoidal areolet, short,

brown. Base of the antenne testaceous. Wings slightly infu- 
mated ; squamule dull, ferruginous ; uervures stout, blackish ; 
stigma large, thick, ovai-lanceolate, bulging out beyond the margin 
of the wing, acuminate at the extremity, emitting the radial 
nervure before the middie. Legs  testaceous, 2 unknown. 
Length, 1 line.
