Mesopolobus zetterstedti (Dalla Torre) comb. n. 



Pteromalus apicalis Zetterstedt, 1838 : 426, o* [nee Nees, 1834]. 



Pteromalus zetterstedtii Dalla Torre, 1898 : 154 [n. n. lor Pteromalus apicalis Zetterstedt, nee 



Nees] . 



Type material. One male, LECTOTYPE, labelled in Zetterstedt's handwriting 

 " P. apicalis <$. Kengis ". 



I cannot correlate this male at present with any female. No other material 

 agreeing with it has been seen.

 Amblymerus subfumatus (Ratzeburg) ; Peck, 1963 : 661-662. 



Type material. Pteromalus subfumatus Ratzeburg. Types presumed destroyed ; 

 but the name has became generally accepted, following its recognition by Nowicki 

 (1939) and Otten (1942a). The latter author probably saw the types. 



Eutelus punctiger Thomson. Syntypes, 4 $. LECTOTYPE labelled " Sm. 

 Bhn " [Smaland, Boheman]. 



Platyterma ecksteini Wolff. Syntypes, Germany," in sylvis Borussiae. Hospes : 

 Lophyrus pini L. ; coluit Prof. Dr. C. Eckstein", presumably in Deutsches 

 Entomologisches Institut, Eberswalde. The species was synonymized with 

 subfumatus Ratzeburg by Nowicki (1939). 



The species was redescribed by von Rosen (1958 : 223-224). 



Widely distributed in Europe (not yet found in the British Isles) ; Canada 

 (introduced) . 



Biology. Chiefly a primary parasite of Diprion spp. (Hym., Diprionidae) , 

 attacking the cocoons ; occasionally hyperparasitic through Ichneumonidae or 

 Braconidae. The majority of imagines have been reared in August and September ; 

 but there is probably an earlier generation emerging in May and June (see Otten, 

 1942a). 



Mesopolobus anogmoides sp. n. 



$. Head and thorax green to blue-green ; gaster with weaker reflections of the same tints, 

 dorsally bronze-black on the disc and the hinder part of the basal tergite. Antennal scape
