ON SOME CYNIPID OAK-GALLS NEW TO THE BRITISH FAUNA. 

 BY EICHAED S. BAGXALL, F.L.S., AND .T. W. H. IIAEEISOX, D.Sc. 



Our Cecidological researches have naturally led us to pay some 

 attention to the gall-wasps of the British Oaks, but, believing that the 

 Cynipidae had been so well worked in comparison with other gall- 

 causers, such as the Cecidomyiidae or JEriophyidae^ we must plead 

 guilty to having somewhat neglected this branch in the past few 3'ears. 

 It did not seem to us that many discoveries remained to be made in the 

 gall-wasps, nor did we realize that one generation or another of those 

 exhibiting that most peculiar phenomenon, an alternation of generations, 

 remained to be discovered or proved. For instance, the placing together 

 of Andricus rliyzomae and A. nodifex as the generations of one species 

 in the following notes has yet to be proved : we have taken this step 

 because of the analogies of A. rliyzomae with the other bark galls
