Fifth report on the noxious and other insects of the State of New York

[Fitch speculatively associates these two species as well as Biarhiza nigra with root galls because he found the adults on the ground or snow, and he thought the adults resembled wasps known to induce root galls on oaks in Europe. They are described based on differences in the adult wasp and none of the descriptions mention a gall.]
