rial (Diplolepis No. 1) on which Fourcroy's quercus was based apparently from the neighborhood of Paris; the source of Olivier's material of scutellaris may also have been central France, or it may have been Manosque (the only locality mentioned in the publication) in Provence.
The present descriptions are based on the published descriptions cited in the bibliography, and on adults and galls which I have from localities in Denmark, Germany, Czecho-Slovakia, Hungary, Austria, France, and England, determined by G. Mayr, Forsius, P. Eigen, Noury, Sajo, Hoffmeyer, Hedicke, and L. H. Weld, as detailed in the above distribution data.
