PTEROMALIDAE OF N.W. EUROPE 479 



Pteromalus pini Hartig sensu Ratzeburg ; Kurdjumov, 1913 : 23.

 Mokrzeckia pini (Hartig) ; Boucek, 1961 : 74. 



Type material. Pteromalus pini Hartig. Syntypes in Zoologische Sammlung 

 des Bayerischen Staates, Munich : a whorl of 8 card-pointed specimens (4 $, 4 $) 

 labelled " Pteromal Pini ". LECTOTYPE, a female whose card-point I have 

 marked with a red spot. 



Pteromalus holiday anus Ratzeburg. Types presumed lost. Boucek (1961 : 75) 

 says that, according to the description and host cited, it could be the same as pini 

 (Htg.). Kurdjumov (1913 : 23) had already remarked that the two were congeneric, 

 and he had seen the type of halidayanus. 



Schizonotus pailloti Ferriere & Faure. Holotype female -in BM(NH), Type 

 Hym. 5. 701 ; I have examined the specimen. 



The synonymy is fully discussed by Boucek (1961 : 74-75). 



France, Germany, Austria, Czechoslovakia, Poland. 



Biology. Hyperparasite of Lepidoptera through Apanteles species (Ferriere & 

 Faure, 1925 ; Mokrzecki, 1933 ; Delucchi, 1958 ; Boucek, 1961). Imagines 

 June-Aug. 



Mokrzeckia obscura sp. n. 



(Text-fig. 357) 



§. Head and thorax bluish green ; gaster bronze-green, its basal tergite mainly blue-green, 

 the remaining tergites extensively suffused with purplish. Antennae fuscous ; proximal half 

 of scape testaceous. Coxae concolorous with thorax ; femora mainly fuscous ; rest of legs 

 testaceous with tips of tarsi brownish. Wing hyaline, veins brownish. Length 2-6 mm. 



Resembles the $ of pini (Hartig) but differs mainly in the characters noted in my key to 

 species (q.v.) Other differences are : in pini the head, pronotal collar, and mesoscutum are 

 densely clothed with short whitish hairs, whilst in obscura the hairs are much sparser and darker ; 

 the propodeal callus of obscura is more sparsely pilose than that of pini, whilst the reticulation 

 of the head, axillae, and scutellum is less fine and less dense then in pini. Although obscura 

 thus differs in several characters from pini, it seems appropriately placed in the same genus ; 

 the structure of the propodeum and petiole is identical in the two species and appears to be 

 characteristic. 



o". Unknown. 



Holotype $. England : Lancashire South, Freshfield, from Betula in the 

 vicinity of pinewood, 5.ix.i96o (Graham), in the Hope Department, University 

 Museum, Oxford.
