New Species of Cynipidae

Cynips quercus mammula, n. sp.

Galls: Hard woody knots at the base of the young shoots on thrifty young white oak trees, Q alba. They affect both the lateral and terminal branches, and as they are of a hemispherical form, and of large size when compared with the branch which always grows out of their summit, they suggest the name above given. They are polythalamous, and the larval cells are arranged as though the eggs had been deposited around the bud before the leaves appeared. The white, thin-walled larval cells are imbedded in woody tissue from which it is almost impossible to detach them. The galls formed around the lateral buds are from one-half to three- fourths of an inch in diameter, but those around the cluster of terminal buds are often an inch in diameter, and instead of a single branch, several are often found growing out of a single gall. They do not seem to affect the growth of the branches the first year, but must seriously injure the tree the following year when the perforated galls begin to decay. This species was very common last year in a thicket which I have searched for galls every season for the last fifteen years without discovering it. The flies are of both sexes and they leave the galls in July.
