Laaerberg, near Vienna; some of them were pierced, but in 
spite of that I obtained many of the gall-flies within the next 
few days. This year, spring being so late, I did not find them 
till May 15th; then, however, in great profusion on the 
Leopoldsberg, near Vienna. They occur as much on shrubby 
oaks as on old trees. The large well-developed galls were 
more or less pierced; they only produced two males, but in 
the course of the same month a number of Platymesopus 
tibialis, Weste.—G. L. Mayr. 
I have seen British specimens of this gall, found by Mr. 
Rothera, near Nottingham. It probably occurs elsewhere ; 
but, as Giraud observes, it occurs early, and the period of its 
existence is very short. It is, consequently, very likely to 
escape observation. In addition to P. tibialis, Mayr obtained 
four species of Ceroptres arator, H., in June of the first 
year.—E. A. Fitch.

? GALL OF CYNIPS ARIES. 
43. ? Cynips aries, Gir—This beautiful gall has been 
sufficiently described by Dr. Giraud in his ‘ Signale- 
ments,’ &c. (Verh. d. zool.-bot. Ges. 1859, p. 871), with this 
exception :—‘ Si je ne me trompe, elle siége dans le pétiole 
@une feuille dont la nervure principale seule a continué a 
croitre eta produit ce grand prolongement qui la surmonte ;” 
for the gall is a genuine bud-gall, being developed from the 
axillar buds, and still retaining the small bud-scales at its 
base. The specimen figured | received from Dr. Giraud,—
