Type material. Pteromalus eupterus Walker. Syntypes, 2 $. LECTOTYPE, 

 the second specimen, bearing a Waterhouse label. 



Pteromalus dimidiatus Walker. One female, LECTOTYPE, bearing a Water- 

 house label. 



Pteromalus capitatus Forster. Types not seen ; I am not aware if they have been 

 critically re-examined in recent years. 



Pteromalus lanceolatus Ratzeburg. Types presumed destroyed. The species was 

 placed in Dinotus [= Dinotiscus] by Kurdjumov (1913 : 10) and his conclusion has 

 been generally accepted. 



D. wichmani Boucek (1967 : 635-637 ; Austria) runs out here but has forewing more extensively 

 pilose, stigma larger.
