less than one-third the length of the wing, subcostal cross- 

 vein situated near its apex ; first longitudinal vein ending at 

 about two-thirds the length of the wing; marginal cross-vein 

 situated just beyond subcostal ; petiole of second longitu- 

 dinal very short, so subraarguial cell is almost triangular; 

 second longitudinal running into the costa some distance be- 

 fore the apex ; costa prolonged beyond its tip, but not reach- 

 ing the apex ; third longitudinal rather indistinct, the apex 

 of its fork situated some distance beyond apex of inner mar- 

 ginal cell, branches slightly divergent ; fourth longitudinal 

 unbrauched ; fifth and sixth longitudinals absent. 



I have specimens of but one species of this genus, but the 

 neuration is so distmct that I think I am justified in establish- 

 ing a new genus for it.
