the pedicellus when the latter is seen in dorsal view ; both anelli subquadrate or at 

 most very slightly transverse ; proximal segments of funicle quadrate, distal seg- 

 ments only very slightly broader than long. Head strongly protuberant at level of 

 antennal toruli ; the face receding strongly and forming an angle of about 100° 

 with the frons. Marginal vein i-6-i-o. times as long as the stigmal vein 



extentus (Walker) (p. 820) 

 - Antennal flagellum stout, its maximum breadth nearly twice that of the pedicellus 

 when the latter is seen in dorsal view ; first anellus distinctly broader than long, 

 the second anellus at least very slightly so ; funicular segments, except some- 

 times the first, distinctly broader than long. Head less strongly protuberant at 

 level of toruli ; the face receding less strongly and forming an angle of 130 "-135° 

 with the frons. Marginal vein 1-9-2 times as long as the stigmal vein 



pachycerus (Masi) (p. 821) 



(Males) 



Only the male of extentus is known to me. It has the head strongly protuberant at the level 

 of the toruli and the face receding strongly, as in the female ; antennae with anelli about as 

 in the female, but the distal segments of the funicle usually a little more distinctly transverse ; 

 temples (Text-fig. 332) strongly produced backwards and appearing acute in dorsal view.

Type material. Pteromalus extentus Walker and P. catillus Walker. Lectotypes 

 designated by Graham (19566 : 258). 



Pteromalus rotundiventris Zetterstedt. Five specimens stand under this name in 

 Zetterstedt's collection, but one does not fit the description. LECTOTYPE, the 

 second specimen (a female) in the series, unlabelled. Three of the other specimens 

 are conspecific with the lectotype. 



Pteromalus druso Walker. Lectotype designated by Graham (19566 : 261, when 

 it was incorrectly stated to be the same as Dibrachoides dynastes Forster). My 

 error has since been pointed out by Boucek (19652 : 35). 



Pteromalus breviramulus Forster. Delucchi (1955a : 174) stated that the badly 

 damaged type is probably the same as catillus Walker [= extentus Walker]. 



Pteromalus eurynotus Forster. Delucchi (1955a : 174) saw the type and stated 

 that it was probably the same as catillus (Walker). 



Widely distributed in Europe. 



Biology. Recorded as a parasite of Cacoecia murinana (Hbn.) (Lep., Tortricidae) 

 in Czechoslovakia (Secretariat, etc., 1957 : 320, 326). Imagines May-August, 

 females overwintering and becoming active in the following spring.
