Cynips corrugis, n. sp.
This species is founded on a single specimen which I took from the claws of a small spider that had evidently just killed it. The spider was in a cluster of the sterile flowers of Quercus prinoides. The capture was made on the 11th of May. This species is remarkable for the almost diaphanous wing veins, the pedicellate abdomen, and the coarsely corrugated sculpturing of the thorax. It is a female, and may have been in the act of ovipositing in the young acorns or the buds of this oak when killed by the spider.
