New species and synonymy of American Cynipidae

Neuroterus thompsoni, new species

Neuroterus rileyi (error) [Kinsey separates N thompsoni from rileyi here but subsequently synonymizes it as a variety of a broader N rileyi in 1923]

Galls.--Pustulate swellings under the bark, each swelling oval, about 2 x 3 mm, and elevating the bark about 1 mm; usually many galls are confluent, around the twig and along it for a length of 2-12 cm. Larval cells, distinct but inseparable, lie in the wood, near the bark, 1-5 to each pustule, and each about 0.7 mm in diameter. On young twigs of Quercus prinoides.
