Cynips quercus confusa n. sp.
Quercus laurifolia
Another curious gall, constructed on the same principle as above [Dryocosmus quercuslaurifoliae] but smaller and not projecting through the leaf, was detected the middle of April.
Galls.--Small, globular, slightly elongate, greenish-yellow, succulent galls, attached to the principal vein on the under surface of the leaf, hollow inside with a pupa-like kernel; fly escaping by perforating a hole through the upper surface of the leaf. Diameter transversely .06; vertically .10 inch.
