PTEROMALIDAE OF N.W. EUROPE 531 



parasite. It was reared under the name H. milleri (Del.) in Belgium and 

 France, as an ectoparasite of mature larvae of Coleophora frischella L., by 

 Delucchi who described (1953) its life-history in detail. He stated that it is generally 

 a solitary, occasionally slightly gregarious, parasite. In two cases larvae of milleri 

 were found to be hyperparasitic on the Coleophora through Br aeon oscillator Nees. 

 Blunck (1944) reared specimens (determined as poecilopus Crawf.) in Germany from 

 Pieris brassicae L. through Apanteles glomeratus L. ; I have examined his material. 

 c?c? and $$ were reared in England (Oxford, Cumnor Hill, 1-3. viii. 1942) from 

 Apanteles sp. (probably zygaenarum Marsh.) found amongst a colony of Zygaena 

 filipendulae L., (G. D. H. Carpenter), material in Hope Dept. On 5.vii.i96o I reared 

 it from a Hyponomeuta (probably padellns L.) on Prunus spinosa L. found at Otmoor, 

 Oxfordshire ; and I have seen specimens reared in 1956 (Germany, Berlin) from 

 Hyponomeuta evonymellus L. Another $ is labelled as having been reared in 

 England (Yorkshire, Bawtry) on 13.vii.1948 from Evetria purdeyi (Durrant) (Lep., 

 Tortricidae) on Corsican Pine (H . S. Hanson). The BM(NH) collection contains a 

 $ obtained at Blekinge, Sweden, in 1936, from pine shoots infested by Evetria 

 buoliana (Schiff.). In the same collection there are also specimens from Germany 

 and Czechoslovakia said to have been reared from cocoons of Neodiprion sertifer 

 (Geoffr.) (Hym., Diprionidae). Both sexes were reared near Oxford in Aug. and 

 Sept. 1951 " from Apion pomonae (F.) in Vetch pod ", (G. R. Gradwell). In April 

 1966 I reared 1 <$, 1 $ from pods of Lathyrus pratensis L. infested by Bruchus loti 

 Payk., collected near London. Imagines most often July-October, occasionally 

 earlier. 



Habrocytus tereus (Walker) comb. n. 

 Pteromalus Tereus Walker, 1839 : 255, <$. 



Type material. One male, LECTOTYPE, bearing a Waterhouse label. 



The female is not yet definitely associated, though I have a female from England 

 which may belong to it and have included the characters of this specimen tentatively 

 in my key. The male is easily recognized because of its extraordinary long antenna! 

 flagellum. 



Britain, Czechoslovakia, Moldavian S.S.R. 

 Biology. Unknown. Imagines in July. 



Habrocytus sp. indet. B 

 I cannot find a name for this species, which is probably undescribed. 



Sweden : Skane, Dalbyhagen, 1 $, 1. viii. 1959, beaten from spruce (Picea) (Graham). 

 I have seen a female which appears to be conspecific, reared in Czechoslovakia from 

 Neodiprion sertifer (Geoffr.), in the collection of Dr. Boucek. 



Habrocytus sp. indet. C 

 England : Oxfordshire, Bald Hill, near Lewknor, 1 $, 15. ix. 1957 (Graham).
