PTEROMALIDAE OF N.W. EUROPE 781 



Urokpis maritimus by Walker himself (1846 : 26) and it seems best to accept this 

 as correct. 



Pteromalus salinus v. Heyden. This is possibly a nomen nudum ; von Heyden 

 gave no description but merely stated that the species often emerged from pupae of 

 Coenia halophila v. Heyd. [=Ephydra riparia Fin.]. It was cited as a possible 

 synonym of maritimus by Walker (1848 : 107). Forster (1856 : 60) stated that he 

 had compared a syntype of maritimus with von Heyden 's specimens of salinus, so 

 that the synonymy may be accepted. 



Pteromalus alope Walker. One female, LECTOTYPE ; Waterhouse label. 



Britain, Ireland, Denmark, Sweden, Germany, Rumania, Moldavian S.S.R. 



Biology. In the Blood coll. (Oxford) there is a female stated to have been reared 

 from a pupa of Themira putris (L.) (Dipt., Sepsidae) in Denmark ; both sexes were 

 reared from Dipterous puparia (? Ephydridae) found amongst Lemna and Azolla 

 at Appleton Pond, Berkshire, England (Dr. B. M. Hobby). Henriksen (1919 : 161) 

 stated that it had often been reared from puparia of Ephydra riparia Fin. in 

 Denmark. Von Heyden's record (under the name Pteromalus salinus) of rearings 

 from the same host has already been quoted. Imagines in May and Aug.-Sept.
