STUDIES OF THE NORTH AMERICAN PROCTOTRUPIDÆ, WITH DESCRIPTIONS OF NEW SPECIES FROM FLORIDA

In this second paper on the North American Proctotrupidœ, I have taken up the sub-family Platygasterinœ, comprising, for the most part, small black species, all parasitic in larvæxs belonging to the Dipterous families Cecidomyiidœ and Tipulidœ.It will be seen that I have recognized in our fauna species in all of the described genera but Iphetrachelus Haliday, and one new genus parasitic on Cecidomyious hickory galls.
