Type material. Pteromalus luniger Nees. Types now destroyed. The inter- 

 pretation of Thomson has been generally accepted. Delucchi (1957a : 420) 

 suggested that the type of nubigera Forster might be taken as neotype of luniger. 



Pteromalus tricolor Walker. Syntypes, 18 specimens. None agrees really well 

 with the description, but 14 are females of luniger (Nees) which suggests that this 

 species formed the basis of his description. One of these females, bearing a 

 Waterhouse label, is selected as LECTOTYPE. 



Pteromalus zonaras Walker. Syntypes, 3 <?. LECTOTYPE labelled " 38. 7. 

 12. 185". 



Phaenacra nubigera Forster. Type $ in Naturhistorisches Museum, Vienna 

 (not seen by the writer). Delucchi (1957a : 401) stated that only one of the 

 specimens so named in Forster's collection agreed with his description ; but he 

 did not mention the labels on the specimen. 



Widely distributed in Europe ; one of the commonest species of the genus. 



Biology. Females of luniger were reared in England (M. F. Claridge), from 

 Tetramesa calamagrostidis (Hed.) (Hym., Eurytomidae), as follows: — Berkshire, 

 Cothill, 5.1V.1957 ; Buckinghamshire, Hell Coppice, 29.iv.1957, Oakley Wood, 

 9.1V.1957, 29.iv.1957 ; Warwickshire, Waverley Wood, 19. v. 1956. Delucchi (1957 : 

 420) stated that it was probably parasitic on Mayetiola spp., but this needs con- 

 firmation. Imagines appear in the field May-September (probably representing 

 several broods). 



Ferriere & Faure (1925 : 227-228) recorded, under the name Homoporus luniger 

 var. braconidis, a species which they had reared from Apanteles glomeratus (L.) ; it 

 is in fact a Dibrachys (q.v.).

A full list of references to this species is given by Peck (1963). 

 Type material. Ceraphon destructor Say. Types presumed destroyed ; see 

 Gahan, 1933 : 94, who gave sound reasons for his adoption of this name.
