synonyms of " aenea " . I have not seen the types of these species but if, as I 

 assume, Gahan was correct in regarding them as conspecific, then all of them must 

 be synonyms of cir cuius (Walker) . 



Peck (1963) used patellana [Dalman] as the valid name for aenea (Walker) sensu 

 Gahan, 1933 (=circulus Walker, nee aenea Walker) ; I do not, however, believe that 

 the true patellana of Dalman was the same as circuhis (for my reasons see above 

 (p. 160) under patellana) .

Biology. Reared in England from Phytomyza petoi Hering (Dipt., Agromyzidae) 

 on Mentha spicata L. (G. C. D. Griffiths) (material in BM(NH). One female reared 

 24.vii.1955 from Phytomyza atricornis Mg., on Sonchus oleraceus L., Oxford district 

 (K. G. V. Smith). The species redescribed and figured under the name fuscicomis 

 (Walker) by Imms (1930) as an endoparasite of the larvae of Oscinella frit (L.) in 

 Britain, was certainly cir cuius (Walker) . Imms unfortunately did not mention any 

 of the characters which would enable one to decide whether his species was circulus 

 (Walker) or aenea (Walker) ; but he did not state that the pronotal collar was 

 margined, whilst his figure 1 of the female shows the basal cell of the fore wing to be 

 virtually bare, features which make it pretty certain that he had circulus before him. 

 Gahan (1933) also recorded it (under the name aenea Walker) as an unimportant 

 parasite of the frit fly ; he cited several other hosts, most of which are Agromyzidae 

 and may be correct, but in view of the confusion between aenea and circulus, it is 

 desirable to have them confirmed.

Type material. Dicyclus aeneus Walker. Four females now stand under this 

 name but two are probably not original material. LECTOTYPE, the first specimen, 

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



Dicyclus tristis Walker. Three specimens now stand here (but one is the 

 lectotype of Miscogaster tristis Walker, 1833). LECTOTYPE, the third specimen, 

 bearing a Waterhouse label. 



Miscogaster cinctipes Walker. One female, LECTOTYPE, bearing a Waterhouse 

 label, also one in C. Ferriere's handwriting " Type CF ". 



Miscogaster nigroaenea Walker. Syntypes, 2 $ ; LECTOTYPE, the first specimen, 

 bearing a Waterhouse label " Dicyclus nigroaeneus Walker ". The species was 

 transferred to Dicyclus by Walker (1846 : 27).
