similar to SiHuiiopsk in appearance, but entirely different 

 structurally; there are only four posterior cells, the third 

 postei-ior vein (coincident with the fourth) branches from 

 beyond half the length of tlie discal cell ; the lower branch 

 of the cubital fork runs to or above the tip of the wing; 

 anal cell closed by the true fifth (apparent fourth) pos- 

 terior vein a little before the border of the wing; the 

 transverse vein situated about one third the length of the 

 discal cell. The wings much marked with spots. Tibiaj 

 without conspicuous bristle.'--, at most with a few weak ones 

 on tho anterior leg? ; intermediate and hind tibia^ with 

 two apical spurs, which can only be seen with difficulty 

 under a lens; abdomen conical; eyes bare, contiguous in 

 tho $ , separate in ? .
