 1. c. xxii, 693. 



Agrees with Synergus except that the radial cellule 

 is open, and like that genus it is inquiline in oak-galls. 

 The frontal groove is short ; the marginal nervure 

 does not reach to the margin of the wiog. 



Besides the one here recorded there are two other 

 European species, namely, 8. Haimi, Mayr, from galls 

 on the Turkey oak, and 8. undulatus ; also on the 

 Turkey oak in Cynips cerricola.
