6 BRITISH GALL-INSECTS. 



qiise insectum fovet/' Avhile Hartig^'s name of ^'fecimdatrixy' 

 besides being of later creation, does positive mischief by in- 

 culcating a serious biological blunder, inasmuch as the insect, 

 far from acting as ''■ fecundairix^ to the bud, positively de- 

 stroys the vitality of the incipient acorn by turning it into a 

 larval and pupal cell. (See Gardener's Chronicle, 1871, 

 No. 36, p. 1162.) The specific name "^em??i^" belongs 

 to the originator of the gall, and following Schenck, Mayr, 

 V. Schlechtendal and others, I believe I act for the best in 

 retaining it for the same. Bred. 



6. C. {A\Mlothrix) radicis, Fab. (Marshall, E. M. Mag. 



iv. p. 7). Bred. 



7. C. (Ajjhilothrix) corticalis, H. = Sieholdi, H. (Miiller^ 



Gardener's Chronicle, 1870, No. 40, p. 1312, fig. 239, 



gall). 

 Bred from barnacle-shaped or crater-like raonothalamous 

 galls on the slender branches of the oak. I hope to give 

 shortly in the " Entomologist's Monthly Magazine" the syno- 

 nymy and natural history of this fine addition to the British 

 list. 



8. C. lignicola, H. (Marshall, E. M. Mag. iv. p. 7^ Muller, 



Proc. Ent. S. Lond. 1869, 25, Scent.). 



Mr. Marshall has sunk C. Kollari, Giraud, as a synonym 

 of lignicola, H. This may be correct, so far as our actual 

 knowledge goes, but I would invite observers to continue to 

 give tl eir attention to the breeding of the Cynipidce from 

 these "marble-galls," as it strikes me that we have hitherto 

 mixed up two or even three species under the name of 

 C. lignicola. The galls are now so common that many may 

 be inclined to pass them over altogethei', while our know- 

 ledge of their makers is by no means satisfactor}^
