Type material. For synonymy and designation of lectotypes see Graham 

 (1957^ : 223-224). The species was redescribed by von Rosen (1958 : 220-221). 



Cinips fuscicornis Fonscolombe. No material found. The description and 

 biology suggests that fuscicornis may have been the same as Mesopolobus tibialis. 



Widely distributed, probably the whole of Europe ; Syria. 



Biology. Reared from various Cynipid galls, especially of Neuroterus spp. and 

 Andricus spp. (for host-list and detailed biological observations, see Askew, 

 19616 : 166-169). According to Askew, tibialis shows a preference for Cynipids 

 which cause leaf-galls, but occasionally attacks those in bud-galls. Normally 

 bivoltine, the two generations appearing in spring and summer, rarely a partial 

 third generation in autumn.

Platyterma remotum Walker. In my paper (1957^ : 226) I placed this as doubt- 

 fully the same as amaenus (Walker). I have re-examined the type $ and am now
