Notes on American Gallflies of the Family Cynipidae Producing Galls on Acorns: With Descriptions of New Species

[Entry for Andricus fimbriatus, new species, a new wasp found on galls similar to Riley's Andricus glandulus.]

Host.--Quercus bicolor

Gall.--This fimbriate-cup gall on bicolor was well described by Riley in 1877 along with a similar one but protruding farther, from a smooth cup on Q. prinoides. Both have often been referred to in literature frequently under the names glandulus and glandulosus. The fly described as Andricus glandulus Beutenmueller, of which the author has a cotype, and associated with the above gall is a red species from an unknown gall. It belongs to the genus Callirhytis and is closely related to C. operatola — the agamic generation of C. operator (Osten Sacken).

The writer has field notes on a similar gall on nine other white oaks of the eastern United States where the recess in which the gall rests is not fimbriate and the gall protrudes half its length or more. See plate 3, figure 12, on prinus [montana] and figure 13 on macrocarpa. As he has not been able to rear any of these as yet it is not known whether any or all of these are caused by the above-described species or which if any is glandulus Beutenmueller.
