Head smooth in front, sidetufts large, roughly spreading, directed 

 forwards. Antennae moderate, in g with long fine cilia (3), basal 

 joint rather stout, without pecten. Palpi moderate, second joint 

 reaching base of antenna?, densely scaled, beneath with rough loose 

 projecting hair-scales throughout, not forming a tuft ; terminal 

 joint as long as second, slender, curved. Thorax smooth. Fore- 

 wings elongate, moderate, hindmargin oblique. Hind wings hardly 

 narrower than forewings, elongate-ovate, hindmargin rounded, cilia 

 !-. Abdomen moderate. Posterior tibias clothed with Ions; hairs. 

 Porewings with vein 7 to hindmargin, 2 from somewhat before 

 angle of cell. Hindwings normal. 



Not very close to any other known genus, though certainly to be 

 placed in this neighbourhood ; perhaps nearest to $aropla, but at 

 present of doubtful origin.
