DKSCRIPriONS OF OAK-GALLS. 207 



ihe others are doubtfully referable to A. glandium. Dr. 

 Giraud says the galls form a hard mass heiween the shell and 

 the nut of the acorn. I may here state t!iat in the autumn of 

 1875 I received, froui the late Edward Newman, a curious, 

 but true, gall, actually formed in a connnon nut (filbert). It 

 was between the nut, with a very marked depression, and the 

 shell near liie base. I believe it came from Mr. Bond. —

Fig. n;}. — Galls of (y) Cijnipa ramicola. 



93. Cynips ramicola, Schlechtendal. — On plate 7 of this 

 work there is a typical specimen of this species, for which I 

 am indebted to Herr von Schlechtendal. I considered it 

 probable that these bark-galls were immature, and that thev 

 were the same as some which, in my collection, are niixed 

 with galls of Aphilotlirix Siebotdi. They occur on the same 

 bough ; and at plate 1, figure 5, are figured in the centre of 

 the upright twig. [See Entom. vii. 52.] — G. L. Mayr. 



After noticing the, to him unknown, ? Cynips superfeta- 

 tionis, the gall of which was described by Giraud as resembling 

 a small acorn grafted on another, and occurring on Quercus 

 pubescens and Q. pedunculaia, Dr. Mayr, in an appendix, 

 gives a little further information on one or two included 

 species, and describes four others. The first, C. ramicola, 

 belongs to the puzzling little group of bark-galls, which 

 includes the single-celled form of A. radicis, A. corlicis, 

 A. rJiizomce, and A. Sieboldi (= coriicaUs); Radicis occurs 

 in Britain commonly ; Sieboldi is widely distributed, and not 

 rare ; whilst Corticis has lately been added to our fauna 

 (Entom. X. 165). Dr. Adler attempted to show that A. corticis 

 and A. rJiizomce were one species; but Dr. Mayr tells us 

 that he only refers to two forms of A. corlicis, and did not 

 know the gall of A. rhizoi/Kc at all. — E. A. Fitch.
