Fig. 109. Wing of L. virens <S. 



Female. Epistoma considerably broader than in the male. Legs 

 as in the male, only the front tarsi simple. Wings hyaline, only with 

 the spot above the end of the discai cell present. 



Length 6 — 7 mm. 



L. virens is a very interesting and beautiful species ; it is rare in 

 Denmark as it has only been taken on Bornholm, where I took it in 

 no small number, sitting on blocks of stone in a brook in the wood 

 Almindingen in August 1911; the piaces of its occurrence were al- 

 ways very shady. 



Geographical distribution : — Widely distributed species ; Europe 

 down into Spain and Italy, and further in North Africa and on 

 Madeira; towards the north to norlhern Sweden. 



25. Campsicnemus Walk. 



Species of small to very small size, and of dark metallic, gener- 

 ally somewhat olive colours. Head broader than thorax, about as 

 broad as high or a little broader; it is almost somewhat square in 

 circumference, but somewhat narrowed downwards; it is slightly 

 arched behind. Vertex slightly excavated, the ocellar tubercle pro- 

 minent. Frons broad, decreasing in breadth towards the antennæ. 

 There are ocellar, outer vertical and postvertical bristles, and a pair 

 of small hairs on the ocellar lubercle. Eyes large, somewhat oval, 

 but with the inner margin angular; they are densely hairy. The 

 facets are distinctly enlarged on the front side towards the epistoma 

 in both sexes. The eyes are separated in both sexes, but very near 

 to each other below the antennæ, and sometimes almost touching; 

 they are only slightly, sometimes almost not, more separated in the 

 female than in the male. The postocular bristles form a single row.
