radicis and sieholdi on the one side, and of A. nodifex with trilineafus 

 and testaceipes (the Jcnown sexual forms of radicis and sieholdi) on 

 the other. 



AVe now realize that much interesting work remains to he done as 

 regards our Oak gall-wasps, and much may be achieved by those Avho 

 have but little spare time, so long as they reside within easy reach of 

 oak woods or shrubberies. 



In the following notes we bring forward 11 forms previously 

 unknown, so far as we are aware, as British. One, however, is the 

 sexual generation of a common British species previously only known 

 from the agamous form.

This is of the sexual generation and the gall occurs on the flower. 

 It is somewhat intermediate between the galls of A. nudus and A. p)ilosuSy 

 being larger than nudus, with the hairs (which are confined to the anterior 

 half) long.
