620 M. W. R. de V. GRAHAM 



Britain, Ireland, Sweden. 



Biology. A common parasite of Phanacis centaureae Forster in the stems of 

 Centaurea species, particularly C. scabiosa L. Other specimens have been reared 

 as a parasite of the early instar larva of Hartigia xanthostoma Eversm. ; these are 

 morphologically indistinguishable from diversus reared from Phanacis centaureae and 

 I consider them to be conspecific. Dr. Claridge, however, thinks that two species 

 may be involved since the host-range is unusual (see Claridge in Graham & Claridge, 

 1965 : 295). The larva of diversus is figured by Claridge in the same paper (1965, 

 figs. 5, 6). Imagines June to August. 



Chlorocytus sp. indet. B. 

 Chlorocytus sp. indet. B, Graham, in Graham & Claridge, 1965 : 289, 295, $. 



Czechoslovakia. 

 Biology. Unknown. 



Chlorocytus inchoatus Graham 



Chlorocytus inchoatus Graham, in Graham & Claridge, 1965 : 289, 295-296, $. 



Type material. Holotype $, England, Oxfordshire, Yarnton district, 29.iv.1957, 

 reared from puparia of Melanagromyza dettmeri Hering in stem of Centaurea nigra 

 L., (M. F. Claridge) in Hope Department, University Museum, Oxford. 



Britain. 



Biology. Reared in Britain by Dr. Claridge, from Melanagromyza dettmeri 

 Hering in stems of Centaurea nigra L. ; and from M. cirsii Rond. in stems of Senecio 

 jacobaea L. The larval head has been figured by Claridge {in Graham & Claridge, 

 1965, figs. 3, 4) and further remarks on the biology of the species are given by him 

 (op. cit. : 296). 



Chlorocytus laogore (Walker)

Pteromalus terminalis Walker, 1836 : 476, $. 



Pteromalus Laogore Walker, 1839 : 267, (J. 



Pteromalus terminalis Walker, 1846 : 44 [nee Walker, 1848 : 114]. 



Chlorocytus laogore (Walker) Graham & Claridge, 1965 : 289, 296-298, $ ?• 



Type material. For discussion of synonymy and designation of lectotypes, see 

 Graham & Claridge (1965 : 296-298) ; in that discussion I have explained why 

 the name laogore was adopted in preference to terminalis. 



Britain. 



Biology. Reared as a parasite of the larvae of Apion sp. in the stems of Rumex 

 spp. (see Claridge, in Graham & Claridge, 1965 : 298). Imagines in June.
