PTEROMALIDAE OF N.W. EUROPE 203 



on Salix (A. H. Hamm). Probably the species is polyphagous. Imagines captured 

 in the field May-September (probably more than one generation). 



[Seladerma diaeus (Walker) comb. n. 



Lamprotatus Diaeus Walker, 1844 : 16, $. 



Type material. One female, designated LECTOTYPE (Type Hym. 5. 822), 

 labelled " Bred from pupa of Vanessa cardui " and " Martin's Falls ". 



Canada : Ontario, Martin's Falls, Albany River, Hudson's Bay (G. Barnston). 



The host data given on the label attached to the specimen is erroneous. Walker's 

 record of Vanessa cardui (1844 : 16) actually refers to Pteromalus puparum (L.), a 

 redescription of which was given immediately below that of Lamprotatus diaeus. 

 This host record has found its way into the current catalogues (e.g., that of Peck, 

 1963 :6oy). The true host will probably prove to be an Agromyzid.]
