BRITISH GALL-INSECTS. O 



very likely that Britain possesses the closely allied D. scii- 

 tellaris, Oliv., as well as D.folii. The former occurs abroad 

 on Quercus puhescens.

3. C. (^Dry op] Uinta) agama, H. (Miiller, Proc. Ent. Soc. 



Lond. 1870, xxxiv., gall). 

 Bred from globular brown galls on the underside of oak 

 leaves ; internal cavity rather large in comparison to the 

 shell of the gall. 



4. C. {DryopUanta) ctivisa, H. 



Bred from pea-shaped, small, depressed galls on the under- 

 side of oak-leaves. When fresh, they have a rosy cheek, 

 dry they are brownish-yellow. The internal cavity rather 

 small in comparison to the size of the gall.

E. M. Mag. iv. p. 8). 

 The maker of the well-known artichoke gall. Mr. Mar- 

 shall has adopted Hartig's later name, in consequence of 

 Linne's insect being probably (?) a Synergus. There is, 

 however, no need for doing so, as this probability cannot be 

 proved now. Linne's description of the gall is quite unmis- 

 takeable, and his diagnosis of the insect is no better and no 

 worse than those of many other of his species, the names of 

 which are strictly upheld in connection with their produc- 

 tions. The term ^' gemincc" conveys a very appropriate 

 meaning, and points at once to the ^' Habitat in Quercu, ubi 

 gemma in gallam imbricatam insequalem terminalem transit,
