C. q. scitula, n. sp.

There is little or no apparent difference [between this and Neuroterus quercusbatatus] in the gall than pertains to the different species of oak on which they grow.

Quercus tinctoria [velutina].

Woody, tuber-like galls, growing on the green branches of Q tinctoria [velutina], sometimes simply an enlargement of the limb, at others entirely checking its growth and covered with leaves. They are from three-fourths to an inch and a half in length, and rather more than half an inch in diameter at the base, tapering to a cone-like point.
