The affinities of this group are clearly nearest with 

 the Cyniphina, as is shown by the length of the second 

 abdominal segment and by the form of the radial 

 cellule, which has the areolet nearly opposite its base. 

 The species may, however, be easily known from the 

 gall-makers by their smooth, shining, impunctate 

 bodies, especially the scutellum, by the tibiae having 

 only one spur ; by the cubitus (when present) issuing 

 from the middle, or near the middle of the transverse 

 basal nervure ; by the incompleteness of the cubitus, 

 so that none of the cubital cellules are closed or com- 

 plete.
