Many authorities have treated this group as allied to the Encyrtidx, and usually 

 place it next to that family, with which it has no affinity whatever. It is clearly a 

 component of the Eulojpliidx, where Dalman first placed it, as is shown by the 

 structural characters of the mesothorax. 



An excellent reversion of the group has been given by Dr. L. O. Howard, in 

 Technical Series No. 1. U. S. Department of Agriculture, Avhere most of the genera 

 have been fully described and figured.
