usual in the genus. Stigma rather large, ovate, the lower edge strongly convex. 

 Marginal cell short and narrow, its first section distinctly shorter than the 

 second; third slightly bowed into the radial cell. Submedian cell slightly 

 longer than the median; recurrent nervure at the apical fourth of the first 

 cubital cell ; first discoidal cell with a petiole above as long as the first section 

 of the radius; second cubital cell larger than usual, distinctly quadrate, being 

 but slightly narrowed above. Cubitus beyond the second transverse cubitus 

 present but weak. 



Described from one specimen, not very well preserved, except the 

 anterior wings which serve to indicate its affinities without the least 

 doubt.
