Mas. Nigro-fnsca, chalybceo snffasa ; antenna fulvce; alee lineis 

 duabus antemediis indelerminatis lineuque postmedia undulata

Male. Blackish brown, chalybeous-tinged, dark cinereous 

 beneath. Antennae tawny, short, stout. Abdomen shorter than the 

 interior border of the hind wings. Wings broad ; two antemedial 

 lines indicated by some black marks ; a postmedial undulating black 

 line, which is incomplete in the hind wings. Fore wings acute ; a 

 submarginal undulating black line, bordered with ferruginous on 

 the inner side and joining the hind part of the tridentate exterior 

 border ; interior border with a long fringe near the tip. Hind wings 

 with a submarginal black line, which is abbreviated hindward ; mar- 

 ginal line black ; exterior border angular in the middle. Length of 

 the body 4 lines; of the wings 10 lines. 



This species hardly belongs to Erosia, but the specimen here 

 described hardly affords sufficient characters to establish a new 

 genus.
