 Hobbya kollari Askew ; Askew, 1961 : 66. 



Type material. Pteromalus stenonotus Ratzeburg. Original material presumed 

 destroyed ; neotype (a female in coll. Thomson standing under the name collaris 

 Thomson) designated by Delucchi (1957 : 143). 



Etroxys (Cecidostiba) collaris Thomson. Syntypes, 8 specimens. LECTOTYPE, 

 a female labelled " Bok " [? Bokebergsslatt] and, in Delucchi's handwriting, 

 " Cecidostiba collaris Ths=syn. stenonotus R." 



Hobbya kollari Askew. Holotype female in Hope Department, University 

 Museum, Oxford. I have re-examined the holotype and paratypes of kollari and 

 consider it to be an unusually large and robust form of stenonota (Ratzeburg). 



Britain, Sweden, Germany, Austria. 



Biology : A common parasite of Biorrhiza pallida (Oliv.) ; occasionally reared 

 from cells of Synergus reinhardi Mayr in the galls of Andricus kollari Htg. (Askew, 

 1961 : 66). Mayr (1903) gave a list of other Cynipid hosts for this species (under 

 the name collaris Thomson). Askew (1961 : 66) stated that stenonota is bivoltine. 

 In the field I have captured specimens in May- June and Aug.-Sept.
