Neuroterus florulentus, new species

Hosts: Quercus dumosa Nutt. and Q. lobata Nee.

Gall: Thin-walled, tan, ovate cells scattered singly or in small clusters among the staminate flowers, bearing at apex on either side the shrunken darker anthers. The base is truncate and excavated, unlike the gall of N. floricola Kinsey. Length 1.5 mm.

Habitat: Types are from galls collected on flowers of Quercus dumosa Nutt., on Santa Catalina Island, Calif., Mar. 31, 1922, when adults were emerging. More emerged by April 10, and more came out and died by April 15. Similar galls were collected at Palo Alto, Calif., on May 3 on flowers of Quercus lobata Nee, and some of the paratypes are from this lot.
