94 Cameron, Flyinoioptcra Oricntalia. 



centre of the petiole raised ; the sides carinate. The 

 traiiverse cubital nervures converge, but do not touch 

 above ; the first is oblique, straight ; the second is oblique 

 above and thicker than below. 



It is doubtful if this can be regarded as ^.Disophrys 

 inasmuch as the branch on the transverse cubital nervurc 

 can hardly be said to exist ; in other res])ccts it agrees 

 fairly well with the genus.
