19081 BEUTENMULLER- CYNZPIDAE 9
In regard to the number of generations in this locality, it appears that there is one in June or earlier and one in July.
The first eggs were found early in June, and gravid females were observed in nature as late as July 24, 1907. Although these
two generations are all that were observed occurring on Rumex, yet my observations were not extensive enough to say that there were not earlier or later ones. I am under obligation to Mr. Eugene Amandus Schwarz, U. S- National Museum, for identification of the species.
NOTES ON HARRIS'S TYPES OF CYNIPIDAE.
BY WILLIAM BEUTENMULLER, NEW YORK CITY.
THROUGH the kindness of Mr. C. W. Johnson, I was enabled to examine the types of the species of Cpipidae described by the late Thaddeus William Harris, whose collection is in the Boston Society of Natural History. RHODITES SEMIPICEUS (Hams).
Cynips semipiceus HARRIS, Rep. Ins. Mass. Inj. Veget, 1841, p. 400; Treat. Ins. New Engl. Inj. Veget. 2nd edit. 1852, p. 436; Treat. Ins. Inj. Veget. 3rd edit. 1863, p. 549; ibid. New Edit. Flint, 1862, p. 549; ibid. 1863, p. 549; ibid. 1880, p. 549. One gall and one female adult are in the collection. The head and abdomen of the specimen are wanting, but from the remaining parts and the characteristic gall, the species may be recognized as being the same as Rhodites fulgem Gillette. Harris's species was heretofore erroneously considered to be a guest-fly (Periclistis semipkeus) of Rhodites radicum by the late R. von Osten Sacken. The type gall is very similar to the one I figured in the Bulletin of the American Museum of Natural History, Vol. XXIII, 1907, plate XLVI, fig. 2. The galls may be found at or on the roots of Rosa rubigmosa, Rosa hmilis, Rosa carolina and probably other species of wild roses.
RHODITES BICOLOR (Harris).

Two galls and one female in fairly good condition of this well known species are in the Harris collection.
DIASTROPHUS DICHLOCERUS (Harris).
Cynip.9 dichlocerus HARRIS, Rep. Ins. Mass. Inj, Veget. 1841, p. 399; Treat. Ins. New Engl. Inj. Veget. 2nd Edit. 1852, p. 435; Treat. Ins. Inj. Veget. 3rd Edit. 1862, p. 549, pi. VIII, figs. 6, 7, 8; ibid. New Edit. Flint, 1862, p. 549; ibid. 1863, p. 549; ibid. 1880, p. 549.
One gall and one female in broken condition. Only the legs, abdomen and
wings are extant. This species has been identified correctly by subsequent writers. It cannot be confounded with any other known American Rhodites. AMPHIBOLIPS CONFLUENS (Harris).
Cynips confluens (HARRIS). Rep. Ins. Mass. Inj. Veget. 1841, p. 397; Treat. Ins. New Engl. Inj. Veget. 2nd Edit. 1852, p. 433; Treat. Ins. Inj. Veget. 3rd Edit. 1862, p. 546, pi. VIII, fig. 9, 10 and figs. 253, 254; ibid. New Edit. Flint. 1862, p. 546; ibid. 1863, p. 546; ibid. 1880, p. 546. Two galls and one female gall-fly are in the collection. Amphibolips spongifica 0. S. is a synonym of Cynips confluens.
AMPHIBOLIPS NUBILIPENNIS (Harris).
Cynips nubilipennis HARRIS, Rep. Ins. Mass. Inj. Veget. 1841, p. 398; Treat. Ins. New Engl. Inj. Veget. 2nd Edit. 1852, p. 434; Treat. Ins. Inj. Veget. 3rd, Edit. 1862, p. 548; ibid. New Edit. Flint, 1862, p. 548; ibid. 1863, p. 548 ; ibid. 1880, p. 548. Four galls and two females in good condition are in the collection. I have care- fully compared Harris's types with Bassett's types of Arnphibolips sculptus and find them to be one and the same species. CALLIRHYTIS SEMINATOR (Harris},
Cynips seminator HARRIS, Rep. Ins. Mass. Inj. Veget. 1841, p. 399; Treat. Ins. New Engl. Inj. Veget. 2nd Edit. 1852, p. 434; Treat. Ins. Inj. Veget. 3rd. Edit. 1862, p. 548; ibid. New Edit. Flint, 1862, p. 548; ibid. 1863, p. 548; ibid. 1880, p. 548. One gall and two female gall flies in good condition are extant. It is the well known white, wooly gall on the twigs of white oak (Quercus alba). It has been cor-
