Key to European Species 

 (Males and Females) 



1 Vertex posteriorly with a strongly raised and sharp transverse crest which 



extends laterally well outside the level of the posterior ocelli ; in frontal 

 view this crest appears like three waves, separated by slight indentations at 

 the level of each posterior ocellus. Antennal flagellum subfiliform, in female 

 relatively thick throughout, the distal funicular segments only slightly 

 transverse. Scutellar frenum more shiny than the rest of the scutellum, 

 smooth at least in the middle. Basal cell of fore wing in female hairy only 

 at extreme apex and along the basal vein. Tibiae testaceous or hardly at 

 all infuscate ...... submontana Boucek (p. 264) 



- Vertex with a weaker transverse ridge which is not sharp and extends at most 



very slightly outside the level of the posterior ocelli, sometimes the ridge 

 is absent ; in frontal view the vertex does not appear to have three waves. 

 Antennae either with the proximal funicular segments narrower than the 

 distal ones ; or with the latter strongly transverse, the fifth nearly twice as 

 broad as long. Scutellar frenum finely reticulate like the rest of the 

 scutellum and relatively dull. Basal cell of fore wing with scattered hairs 

 over its distal third to half ......... 2 



2 (1) Vertex posteriorly with a fairly distinct transverse ridge which extends 



slightly laterad of the posterior ocelli. Antennal flagellum strongly clavate, 

 the funicle proximally more slender with its second segment only slightly 

 more than half as broad as the fifth segment. Propodeum nearly smooth, 

 with plicae strong, often also with supplementary carinae between them and 

 the median carina. Hind margin of basal tergite of gaster deeply, rectan- 

 gularly emarginate ...... arenaria Erdos (p. 265) 



— Vertex without a ridge or with at most a weak one which does not extend 



laterad of the posterior ocelli. Antennal flagellum less strongly clavate, the 

 funicle relatively thicker proximally with its second segment not much 

 narrower than the fifth segment. Propodeum delicately wrinkled, the 

 wrinkles tending to radiate from the base of the median carina ; plicae 

 weaker, no obvious supplementary carinae present. Hind margin of 

 basal tergite of gaster shallowly emarginate . . classeyi Boucek (p. 265)
