PTEROMALIDAE OF N.W. EUROPE 41 



Biology. Parasite of Tetramesa species (Eurytomidae) in culms of Gramineae ; 

 Boucek (1958 : 371) records having reared it in Bohemia from Tetramesa [=Harmo- 

 lita] calamagrostidis (Hed.) in culms of Calamagrostis. Imagines Apr.-July. 



According to Boucek (1958 : 371) most females have rudimentary wings, the 

 form with fully developed wings being comparatively rare.

 are now known. 



Key to European Species 

 (Females) 

 The following key is adapted from that of Boucek (19616 : 474). 



1 Petiole of gaster about 1 -5 times as long as broad, its length more than half the median 

 length of the propodeum. Disc of propodeum, except the median crenulated 

 double groove, smooth. Scutellum moderately convex, its reticulation sharp and 

 deep, with the bottom of the individual areolae shiny. Fore wing with hyaline 

 band between the fuscous fasciae equally wide throughout ; postmarginal vein 

 longer than the stigmal vein. Antenna with anellus transverse ; flagellum 

 relatively less slender ....... versicolor Walker (p. 41) 



- Petiole of gaster transverse, its length only about one quarter the median length of 

 the propodeum. Disc of propodeum distinctly reticulate. Scutellum weakly 

 convex and quite dull, its reticulation extremely dense, much denser than that of 

 the mesoscutum. Fore wing with hyaline band constricted in the middle ; post- 

 marginal vein about as long as the stigmal vein. Antenna with anellus quadrate ; 

 flagellum relatively more slender ..... clavatus Boucek (p. 42)

Type material. One female, designated as type by Kerrich (1957 : 270) ; it 

 bears a Waterhouse label.

Biology. Unknown. Fulmek (1957 : 172, 174) mentions it as an Aphid parasite 

 but Boucek (1958 : 371) thinks that it probably parasitizes insects living in grasses, 

 as does Pannoniella. Imagines June-Aug.
