Type material (all Walker lectotypes bear Waterhouse labels, unless otherwise 

 stated). 



Eutelus semotus Walker. Syntypes, 4 $. LECTOTYPE, the second specimen. 



Pteromalus imbutus Walker. 10 specimens (possibly some are not original 

 material). LECTOTYPE $, the third specimen. 



Pteromalus solutus Walker. One female, LECTOTYPE. 



Pteromalus cupreus Walker. Syntypes, 3 $. LECTOTYPE, the second specimen. 



Pteromalus lugubris Walker. Syntypes, 2 $. LECTOTYPE, the second specimen. 



Pteromalus maerens Walker. Syntypes, 3 $. LECTOTYPE, one marked 

 " Type CF " [C. Ferriere]. 



Pteromalus thalassinus Walker. One female, LECTOTYPE (possibly holotype). 



Pteromalus equestris Walker. One female, LECTOTYPE (possibly holotype) ; it 

 is recognizable, though much damaged. 



Pteromalus pione Walker. Syntypes, 3 <$. LECTOTYPE, a specimen labelled 

 only " Pione " in Walker's handwriting. 



Pteromalus mutia Walker. Syntypes, 3 £. LECTOTYPE, the third specimen ; 

 it has shorter funicular segments and scape than typical males of semotus but it may 

 be conspecific with it. 



Pteromalus variabilis Ratzeburg. Location of holotype $ unknown (probably 

 destroyed). In my opinion it is most likely to have been the same as semotus 

 (Walker) ; Boucek (19650 : 35) also takes this view. 



Pteromalus glautias Walker. One female, LECTOTYPE. 



Pteromalus amnisos Walker. One female, LECTOTYPE. 



Habrocytus parvinucha Thomson. Syntypes on 11 pins. LECTOTYPE, a female 

 labelled " Hbg " [Halsingborg] and " parvinucha Ths ; it is a very small specimen. 



Habrocytus microgastris Kurdjumov. Syntypes, Russia, province of Charkov, 

 Krasnokutsk, 1907, reared from Apanteles glomeratus L. and A. pieridis Bouche^ ; 

 location unknown to me. The description suggests that the species is identical with 

 semotus (Walker). 



The specimens recorded by Blunck (1944) as Habrocytus poecilopus (Crawford) 

 are identical with semotus. I am not able to say whether Blunck's determination 

 was correct because I have not seen the type of poecilopus. Crawford described 

 this species (1910 : 21-22, $, % as Hypopteromalus poecilopus) from material from 

 Europe ; the type is catalogued as no. 12974 in U.S.N.M. The description is 

 inadequate for recognition of the species. 



Habrocytus milleri Delucchi & Verbeke. Type $ in European Laboratory of 

 C.I. B.C., Feldmeilen, Zurich ; paratypes in Institut Royal des Sciences naturelles 

 de Belgique, Brussels. Described from material reared at Virton, Luxemburg, 

 and at Montmedy, France, in Aug.-Sept. 1951. I have examined the types, which 

 are conspecific with semotus (Walker). 



Europe (widely distributed). 



Biology. This species develops chiefly as a primary parasite or a hyperparasite, 

 of various lepidoptera ; it has also been reared in association with certain Coleoptera, 

 but in these cases it is not known whether it was a primary or secondary
