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

Oak-potato Gall-fly, Cynips Quercus-batatus, new species.

A large, hard, uneven swelling, three-fourths of an inch thick and twice or thrice as long, resembling a potato in its shape, growing on white oak twigs more distant from their ends than the Oak-tumor.

This gall might be mistaken for a large example of the Elliptic variety of the one first described ["Cynips quercus-arbos"--Callirhytis clavula?], but at each end the swelling arises much more abruptly from the limb, and on all sides of it, whereby the limb is wholly obliterated. Its surface is coated with a glaucous pale blue bloom. Internally it is of a dense corky texture in which are hard woody spots.
