Type material. For synonymy and designation of lectotypes see (Graham 

 (1957^). In that paper I designated as lectotype of Eutelus pedunculi Thomson 

 the second specimen in the series, labelled " Hbg " [Halsingborg]. Later von Rosen 

 (1958 : 233) disputed my selection, stating that the specimen in question lacked the 

 antennal flagella. He selected another female, the fourth in the series, labelled 

 " Rsio " [Ringsjo] as lectotype. Thomson cited Tvedora as type-locality, and 

 von Rosen pointed out that Ringsjo is nearer to Tvedora than Halsingborg. I am 

 willing to accept his lectotype designation. 



Britain, Sweden ; very local and apparently rather rare. 



Biology. Reared in England from Andricus curvator (see Askew, 19616 : 172). 

 The species is apparently univoltine (imagines June- July). 



I have seen some female Mesopolobus from Central Europe which have a fuscous 

 cloud on the fore wing, below and touching the stigma, but which do not appear 

 to differ in other respects from albitarsus. They may be a form of that species.
