THE INSECTS OF NEW JERSEY. 651 



Super-family PROCTOTRYPOIDEA. 



In this series we have species in which the ovipositor is retractile into 

 and comes from the end of the abdomen. All of them are parasites, and 

 all stages of other insscts may be infested. The tendency is to com- 

 pleteness of venation, and the antennae are usually straight. Among 

 them- are the smallest of the parasites, and on the other hand some of 

 them are of good size. The late Dr. W. H. Ashmead has added much 

 to our knowledge of this super-family, and some of his results are in- 

 cluded here.
