Type material. Dicyclus circulus Walker. Syntypes, 2 $. LECTOTYPE, one 

 bearing a Waterhouse label and another in C. Ferriere's handwriting " Type CF ". 



Dicyclus fuscicornis Walker. Syntypes, 2 $. LECTOTYPE, the first specimen, 

 bearing a Waterhouse label. 



Pteromalus palpigerus Zetterstedt. One male, LECTOTYPE, labelled in 

 Zetterstedt's handwriting " Pt. palpi-gerus. $ PTalvig ". The head and gaster are 

 missing but from the remains I consider it the same as circulus (Walker). 



Pteromalus brevicornis Zetterstedt. One male, LECTOTYPE (but probably 

 holotype), labelled in Zetterstedt's handwriting " P. brevicornis^. Kengis ". 



Miscogaster daiphron Walker. One female, accepted as TYPE ; Waterhouse 

 label, also one " Type Gahan 1927 ". 



Miscogaster crius Walker. Syntypes, in BM(NH), one female ; and in Haliday 

 collection, two females (nos. 681, 684), of which one is labelled " Crius " in Walker's 

 handwriting, while the other bears a green label indicating Irish origin. 

 LECTOTYPE, the female in BM (NH), which is labelled " Crius " in Walker's 

 handwriting. 



Miscogaster suilius Walker. Syntypes, 2 cJ. LECTOTYPE, the first specimen, 

 bearing a Waterhouse label. 



The species identified by Gahan (1933) as Halticoptera aenea (Walker) was 

 evidently not aenea, but circulus (Walker). In the same paper Gahan cited fuscicornis 

 (Walker) as a synonym of the supposed aenea; he identified fuscicornis on the basis 

 of American specimens which had been compared with the types of fuscicornis, and 

 on a probable syntype of that species sent to him, by Waterston. He also stated 

 (1933 : 119) that he had later seen the type female of aenea, and concluded that it 

 was the same species as fuscicornis. Moreover, he cited (ibid. : 116) fuscicornis as 

 interpreted by Imms (1930) as being the same as aenea. In his redescription of the 

 supposed aenea, Gahan mentioned (ibid. : 117) that the pronotal collar of the female 

 is not margined, and that the fore wing is bare basally except for a few hairs in the 

 costal cell. Further he stated (ibid. : 120) that the maxillary stipes of the male is 

 not greatly enlarged and is not visible from above. All these features indicate that 

 the species he had before him was circulus and not aenea. Gahan also cited (ibid. : 

 116) the names of five other North American species which he considered to be
