provided with sensilla, as in Text-fig. 276. Thorax strongly arched dorsally. 

 Propodeal callus with six or more bristles ; hind coxae with some hairs on 

 their dorsal surface. Eyes of <$ very large, approximated on vertex and 

 touching the posterior ocelli ; antennal scape not swollen 



STENOPHRUS Forster (p. 333) 

 Fore wing with at least a narrow speculum on the upper surface, in most 

 species it is present on both surfaces of the wing ; basal cell at most pilose 

 in its distal third. Either the antennae have at most two large funicular 

 segments provided with sensilla (Text-figs. 277-280) ; or if with three large 

 segments (Text-fig. 276) then the thorax is flattened dorso-ventrally. 

 Propodeal callus with only one to four bristles ; hind coxae bare dorsally. 

 Eyes of o" large or small ; antennal scape sometimes swollen (Text-fig. 275)

Key to European Species 



1 Female with gaster not strongly compressed, not longer than head plus 



thorax ; combined length of pedicellus and flagellum less than breadth of 

 head ; pedicellus slightly longer than combined length of funicular segments 

 one and two ; all funicular segments transverse ; clava nearly as long as the 

 four preceding funicular segments together ; scape slightly shorter than an 

 eye, 4 to 4-5 times as long as broad, reaching only about two thirds the 

 distance from the toruli to the median ocellus. Male unknown 



monticola Forster (p. 331) 

 - Females with gaster very strongly compressed like a knife-blade, much longer 



than head plus thorax ; combined length of pedicellus and flagellum equal to 

 or greater than the breadth of the head ; pedicellus shorter than combined 

 length of funicular segments one and two ; at least the first funicular 

 segment slightly longer than broad, the remaining segments not or hardly 

 transverse ; clava at least slightly shorter than the four preceding funicular 

 segments together ; scape at least very slightly longer than an eye, 4-8 to 

 6-5 times as long as broad, reaching nearly or quite to the median ocellus. 

 Males : for characters see below ........ 2 



2 (1) Female with antennae (Text-fig. 268) with all funicular segments longer than 



broad, the fifth 1 -3 to 1 -5 times as long as broad ; clava at most as long as, 

 but usually slightly shorter than, the three preceding funicular segments to- 

 gether ; scape about 1-2 times as long as an eye, 6 to 6-5 times as long as 

 broad. Male with mid and hind tibiae, especially the latter, (see Text-fig.
