Key to European Species 

 (Females) 



i Hind tibia with two distinct spurs. Fore wing with basal cell with scattered 



hairs over most of its surface ; costal cell broad, length to breadth about 8 : i. 

 Antennae with combined length of pedicellus and flagellum distinctly less 

 than breadth of head ; funicle stouter than the pedicellus, its segments 

 subquadrate or slightly transverse. Gaster dorsally convex. Mesoscutum 

 with rather indistinct piliferous punctures. Malar space slightly more than 

 half length of an eye ........ sp. indet. (p. 826) 



- Hind tibia with only one spur. Fore wing with basal cell bare, or with at most 



a very few isolated hairs ; costal cell narrower, length to breadth about 



10 : 1 . . . . . . . . . . . . 2 



2 (1) Apical margin of fore wing ciliate except sometimes for a short space just beyond 

 the postmarginal vein. Antennae with combined length of pedicellus and 

 flagellum slightly less than breadth of head ; flagellum rather stout, 

 segments of funicle subquadrate. Malar space only about half length of an 

 eye. Gaster dorsally flat or slightly concave . . fimbriatus Boucek (p. 826) 



- Apical margin of fore wing without cilia. Antennae with combined length of 



pedicellus and flagellum approximately equal to breadth of head ; flagellum 

 slender, proximally not stouter than the pedicellus. Malar space about two 

 thirds the length of an eye. Gaster dorsally convex. Propodeum, Text-fig.

(Males) 



1 Fore wing with apical margin mainly to entirely bare. Antennae with pedi- 



cellus fully twice as long as broad ; flagellum rather slender ; at least some of 

 the proximal funicular segments slightly longer than broad, in large specimens 

 segments 1-4 may be very distinctly longer than broad, and only the sixth 

 segment quadrate ...... distinguendus (Forster) (p. 824) 



- Fore wing with apical margin ciliate. Antennae with pedicellus about 15 



times as long as broad ; flagellum relatively stouter ; all funicular segments 

 subquadrate ........ fimbriatus Boucek (p. 826)
