Galls of this species were sent me by Mr. Trevor Kincaid, of Olympia, Washington, who writes that they were collcted from the twigs of Quercus garryana. The galls are ellipsoids, from 5 to 7 mm. in greatest diameter; they are smooth, monothalamous and snuff coloured, both externally and internally, and are attached by a small projection to the side of small twigs.
