Body linear, nearly bare, rather short. Head round, flat above. Face 

 pilose. Eyes reniform. Ocelli three, the middle one in front, hardly

 teen-jointed, rather stout, almost cylindrical, not more than half the

 convex. Scutellum small. Wings moderately broad, pubescent, parallel 

 in repose subcostal vein ending at much less than half the length of 

 the wing ; radial springing from the subcostal near its base, ending at 

 a little in front of the tip of the wing ; cubital and subapical long, 

 springing from an angular transverse veinlet, the latter forked at a
