S.pallipes is common in Denmark; at Lersøen, Amager, Dyre- 

 haven, Tyvekrog, and on the little island Egholm at Skelskør; on 

 Funen at Hoffmansgave, and on Fænø; in Jutland in Grejsdalen 

 at Vejle, at Horsens, Nymindegab and Ringkøbing Fjord, Frijsen- 

 borg, Gjerlev near Randers Fjord, Holstebro, Struer, and Ravnkilde 

 near Skørping; finally on Bornholm at Rønne, Hasle, Allinge and in 

 Almindingen. My dates are ^®/5 — ^^/lo. It occurs at the horders of 

 water in grass and low herbage, and not rarely on commons and 

 marshes near the shore, sometimes in great numbers; on Egholm I 

 found it swarming over small pools on the salt marshes on ^^^/o. The 

 different varieties occur together. 



Geographical distribution : — S. pallipes is a common and very 

 widely distributed species; all Europe down into Spain an Italy; 

 towards the north to middle Scandinavia; further in Asia Minor, on 

 Madeira and the Ganary Islands.

 whitish below. Antennæ black, somewhat long but shorter than in 

 pallipes; arista apical, about as long as the third joint; the second 

 joint inserted into the third in the same way as in pallipes; the first 

 joint (as far as I could detect) without hairs above. Thorax æneous,

 irregularly biserial, especially behind. Pleura greenish, greyish pruinose ; 

 metaepimera yellow; propleural hairs white; scutellum with some hairs at 

 the margin and some few above. Abdomen blackish, the most of the 

 second segment and the sides yellow in such a way that abdomen may be 

 termed yellow with somewhat triangular, blackish spots above, turning 

 the point forwards and connected with each other; on the second segment 

 the spot is small and thus the segment almost quite yellow; the first 

 segment is likewise yellow, a little darkened at the hind margin; the
