E. rubrirena limps. Forewing lustrous dark brown, dusted with grey and strewn with black, the 
proximal margin of the basal area red-brown; the anterior transverse line is indistinctly double rmdulate, the 
posterior line indistinct, dentate, blackish; the ring-macula is absent, the reniform macula is encircled with

E. uniformis Sm. (21 1) is on the forewing grey, dusted with purple red and strewn with greyish-
