 larger, daik brown spots along the costal margin at Sc2, Sci, 

 El, /?2, and R^. Venation: Sc2 retreated some distance 

 from the tip of Sci, Sc^ being at about one-third the distance 

 between the origin of Rs and the tip of Sci ; r on R2 at 

 about its own length bej'ond the fork of i?2+3 ; ^2+3 about 

 equal to the basal deflection of Cmj ; cell 1st M.2 closed ; 

 m transverse ; inner end of cell \st M^ narrowed ; basal 

 deflection of Cu^ before the fork of M, the distance about 

 equal to r-m ; 2nd Anal vein sinuous, as iu the subgenus 

 Erioptera.
