Laaerberg, near Vienna; some of them were pierced, but in 

 spite of that I obtained many of the gall-flies within the next 

 i'ew 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, Westw. — G. L. Mayr. 



1 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.

43. ? Cynips aries, Gir. — This beautiful gall has been 

 sufficiently described by Dr. Giraud in his ' Signale- 

 ments,' &c. (Verb. d. zool.-bot. Ges. 1859, p. 371), with this 

 exception : — " Si je ne me trompe, elle siege dans le petiole 

 d'une feuille dont la nervure principale seule a continue a 

 croitre eta produit ce grand prolongeuient qui la surmonle;" 

 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 1 received from Dr. Giraud. — 

 G, L. Mayr.
