 middle of the abdomen, corium protracted into a narrow margin 

 along the outside of the membrane; nervures of the membrane 

 straight, a few of them nearest the margin, and on the middle, 

 forked at tip. Scutellum flat, elevated at base. Sternum broadly 

 succate. Legs long, slender, gradually enlarging to the tiji; a double 

 row of teeth on the underside of femora near the tip, the one row

 the rows is a broad sulcus; tibite simple, slightly enlarged at tip. 

 Stigmata of the venter situated near to the connexivum, a very little 

 in advance of the middle of the segments, connexivum dilated and 

 upcurved on the middle segments. Female, middle of the apical 

 margin of the sixth segment split and emarginated, also transversely 

 incised, the genital segment originating beneath this, broadly trian-
