The well-known galls of this Central European variety appear in the middle of June, becoming mature by the end of August, at which time the adult insects are developed within the galls (acc. Rössig 1904). Rössig points out that in the first six weeks the larva attains a length of only 300 μ, but that in the next two weeks it reaches a length of at least 2 mm. Emergence occurs from mid-October to early December. There are records for emergence in Austria in October (acc. Mayr 1884), in late October and early November in northern Germany (acc. Adler 1881), from November 10 to 22 in England (acc. Mayr-Fitch 1876), and in early December in Lorraine (acc. Kieffer 1901). The dates on my Danish material (Hoffmeyer coll.) are October 10, 12, 16, 19, 26, and 30, and November 2, 3, 5, and 8. Réaumur (1737) and Schenck (1865) both recorded spring emergence, but the first record means little since there is internal evidence in the Mémoires that Réaumur never distinguished the true gall makers from the inquilines which emerge in the spring; and
