Key to European Species 

 (Females) 



1 Gaster lanceolate, 4-5 to 5-5 times as long as broad, 1-5 to 1-9 times as long as 



head plus thorax ; last tergite twice or more than twice as long as its basal 

 breadth, the penultimate tergite nearly twice as long as broad, the ante- 

 penultimate about as long as broad ; basal tergite with a short, transverse 

 basal fovea. Head in dorsal view only 2 to 2-1 times as broad as long . 2 



- Gaster at most hardly three times as long as broad, at most 1-4 times as long 



as head plus thorax ; last tergite at most 1-3 times as long as its basal 

 breadth, the two preceding tergites relatively shorter than in the alternate 

 couplet ; basal tergite with a long, subtriangular basal fovea which reaches 

 nearly half way towards the hind margin of the tergite. Head in dorsal view 

 2-25 to 2-55 times as broad as long ....... 3 



2 (1) Propodeum (medially) fully two thirds as long as the scutellum and produced 



well behind the level of the bases of the hind coxae ; plicae distinct, and 

 rather sharp both at the front and hind margins of the propodeum ; costula 

 distinct. Antennal scape reaching only to the median ocellus ; combined 

 length of pedicellus and flagellum only slightly greater than breadth of 

 head ; first funicular segment about twice as long as broad, sixth quadrate ; 

 sensilla in one row on all segments of the funicle. Fore wing with postmar- 

 ginal vein somewhat shorter than the marginal vein, the latter more than 

 twice as long as the stigmal vein ..... agrili Boucek (p. 581) 

 Propodeum (medially) only about one third as long as the scutellum and pro- 

 duced only slightly behind the level of the bases of the hind coxae ; plicae 

 sharp at hind margin only ; costula absent. Antennal scape reaching above 

 the level of the vertex ; combined length of pedicellus and flagellum 

 about 1 -4 times breadth of head ; first funicular segment somewhat more 

 than twice as long as broad, sixth slightly longer than broad ; sensilla 

 numerous, arranged in three to four rows on the proximal segments, in 

 two rows on the distal segments, of the funicle. Fore wing with post- 

 marginal vein slightly longer than the marginal vein, the latter hardly twice 

 as long as the stigmal vein .... abdominalis Delucchi (p. 580) 



3 (1) Head in dorsal view 2-25 to 2-35 times as broad as long ; temples nearly one 



third as long as eyes. Propodeum shorter, medially rather more than one 

 third as long as the scutellum. Dorsellum weakly reticulate, the sculpture 

 hardly raised above the general surface, rather shiny. Antennae with first 

 funicular segment as long as the clava and about twice as long as broad 



spiracularis (Thomson) (p. 581) 

 Head in dorsal view (Text-fig. 428) 2-5 to 2-55 times as broad as long ; 

 temples about one quarter as long as eyes. Propodeum longer, medially 

 rather more than half as long as the scutellum. Dorsellum strongly reticu- 

 late, relatively dull. Antennae with first funicular segment somewhat shorter 

 than the clava, and at most 1-7 times as long as broad
