Primaries flesh-coloured ; a yellow-centred darker rounded spot at the end of the cell 
and two slightly darker but indistinct bands beyond the cell, the outer one angulatecl ; a 
slender ferruginous marginal line, fringe white : secondaries pale stramineous, the interno-

in the structure of the antennas it seems to agree best with members of the Notodontidas,
