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 places 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 northern 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 antennse. There are ocellar, outer vertical and postvertical bristles, and a pair of small hairs on the ocellar tubercle. 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 antennae, 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,. Please note that these i
