Szel.] by Szelenyi (1956 : 171, 180) as a primary parasite of Timaspis papaveris 

 Kieffer in the stems of Papaver somniferum L. ; and from galls of Phanacis centaureae 

 Forster in stems of Centaurea sadleriana Janka. Imagines chiefly June-Sept, 

 (one record for April, specimens reared under artificial conditions). 



Homoporus crassiceps Thomson 



Homoporus crassiceps Thomson, 1878 : 66, $. 



Homoporus crassiceps Thomson ; Delucchi, 1957a : 406, 412, $. 



Type material. Syntypes, 4 specimens. LECTOTYPE £ labelled " Hg " 

 [Halsingborg] on a green label ; " crassiceps Ths " ; " HOMOPORUS crassiceps 

 Ths. V. Delucchi det." ; and " LECTOTYPE " on a red label. 



I am not sure whether crassiceps may not be a form of subniger (Walker) ; but 

 none of my own specimens of the latter agree completely with the type of crassiceps, 

 so the possibility that the latter is a valid species should not be ruled out. 



Sweden. 



Biology. Recorded by Lebedeva (1926) as a parasite of Theresia (Procris) 

 ampelophaga Bayle (Lep., Zygaenidae) in U.S.S.R. ; but this record cannot be checked 

 and the parasite may not have been correctly identified. 



Homoporus arestor (Walker) 



Pteromalus A restor Walker, 1848 : 124, 179, $. 



Homoporus chlorogaster Thomson, 1878 : 66, $ $. 



? Homoporus (Pseudomerisus) simplex Szelenyi, 1956 : 171, 177-179, $. 



Homoporus chlorogaster Thomson ; Delucchi, 1957a : 406, 414, $. 



Homoporus arestor (Walker) Boucek, 19655 : 35. 



Type material. Pteromalus arestor Walker. One female, LECTOTYPE (possibly 

 holotype), bearing a Waterhouse label. 



Homoporus chlorogaster Thomson. Syntypes, 10 specimens. LECTOTYPE, a 

 female labelled " Lund " and " chlorogaster Ths ". The species was placed in 

 synonymy with arestor by Boucek (1965^ : 35). 



Homoporus {Pseudomerisus) simplex Szelenyi. Holotype $ (not seen), Hungary, 

 Matra, Sasko-Disznoko, 13. ix. 1949, presumably in Hungarian National Museum, 

 Budapest. According to the description it might be the same as arestor (Walker) 

 (= chlorogaster Thomson). Szelenyi had not seen the types of arestor or chlorogaster ; 

 he included the latter in his key to the species of Homoporus (1956 : 172), on the 

 basis of Thomson's description. 



Britain, Sweden, Central Europe. Apparently uncommon (or perhaps very 

 local) . 



Biology. Unknown.
