Subfamily COSMOPHORINAE 



Placement of this group in the cyclostomine section of the Braconidae 

 seems not to be tenable. The clypeus, while impressed, is not circularly emar- 

 ginate as in cyclostomines, and in habits and larval structure the species 

 resemble the Euphorinae. For the present the group is treated here as a 

 distinct subfamily, but it is removed from the cyclostomine section of the 

 family and placed after the Euphorinae. It may eventually need to be rein- 

 corporated in that subfamily.
