Key to European Species 



(Females) 



1 Mesopleuron entirely reticulate. Antenna (Text-fig. 452) with flagellum strongly 

 clavate ; first funicular segment slightly transverse, the following segments more 

 strongly so, the sixth nearly twice as broad as long. Head in dorsal view hardly 

 twice as broad as long ; POL greater than OOL. Thorax about 1 -75 times as long 

 as broad. Head and thorax black with very weak violet and bronze reflections. 

 Antennal scape black. Femora usually mainly fuscous. Structural features, 

 text-figs. 452-454, 460-462 ..... corynocera Graham (p. 598) 



- Mesepisternum with a partly to wholly smooth triangular area below the base of the 



hind wing. Antenna (Text-fig. 455) with flagellum only slightly clavate, the 

 funicle nearly cylindrical ; funicular segments subquadrate, or the distal segments 

 very slightly transverse. Head in dorsal view (Text-fig. 459) 2-15 to 2-2 times as 

 broad as long ; POL less than OOL. Thorax about 1-5 times as long as broad. 

 Head and thorax dark blue or greenish blue. Antennal scape mainly to wholly 

 testaceous. Legs, except coxae, testaceous, with the femora at most slightly 

 darkened. Other structural features, text-figs. 457, 458 . livida Graham (p. 598) 



(Males) 



1 Mesopleuron entirely reticulate. Antenna with combined length of pedicellus and 

 flagellum much less than breadth of head ; flagellum distinctly clavate ; first 

 funicular segment quadrate to distinctly transverse, sixth from 1-7 times to 

 nearly twice as broad as long ; scape hardly expanded distally, with only an 

 indistinct boss ........ corynocera Graham (p. 598) 



- Mesepisternum with a partly to wholly smooth triangular area below the base of the 



hind wing. Antenna (Text-fig. 456) with combined length of pedicellus and 

 flagellum nearly equal to breadth of head ; flagellum hardly clavate, only the clava 

 slightly broader than the rest ; funicular segments quadrate, or the proximal ones 

 slightly longer than broad ; scape slightly expanded in its upper half, with a long 

 shiny boss which extends half way down .... livida Graham (p. 598)
