what long and narrow, greyish brown tinged, with the apical part of 

 the subcostal cell brown, and with the cubital, discai and postical 

 veins brown seamed, besides with a blackish brown spot on the 

 posterior cross-vein and on the last part of the discai vein at the 

 bend; the brown seaming of the apical part of the radial and cubital 

 vein more or less coalescing so that the anterior apical part of the 

 wing is brown. Veins blackish, discai vein with a somewhat large 

 bend, Squamulæ yellowish brown, with a pale fringe. Halteres yel- 

 low or yellowish brown. 



Female. Epistoma somewhat broader than in the male, especi- 

 ally above. Antennæ of about the same length. Thorax more brown 

 pruinose. Legs about as in the male, front femora likewise thickened, 

 and posterior femora long; the tibiæ more bristly; but the legs are 

 simple, the front tibiæ have not the bifid spine and the apical spine 

 is smaller, the middle tibiæ and tarsi quite simple, without curled

S. notatus is not common in Denmark; Copenhagen in a garden. 

 Amager; on Funen at Hoffmansgave , and in Jutland at Thisted. 

 My dates are ^'^/c — ^'^/s. It occurs in grass and low herbage, and it 

 may be found on commons near the shore at water pools, but also 

 on quite dry fieids, thus I took a number, but only females, on a 

 dry, stony field at Thisted. 



Geographical distribution: — Europe down into Italy; towards 

 the north to middle Sweden, and in Finland and also in Siberia. 

 Verrall records it (Ent. Month. Mag. XVI, 1905, 191) from England 

 from: "amongst marshy herbage near the sea-coast".

Species of small or medium size and of a characteristic short, 

 congested shape. The colours are dark, olive or greenish to coppery, 

 but generally not much metailic. Head as broad as or a little broader 

 than thorax, either higher than broad, or with height and breadth 

 about equal; it is a little arched behind. Vertex more or less, gener- 

 ally distinctly, excavated, the ocellar tubercle somewhat prominent. 

 Frons broad, a little decreasing in breadth towards the antennæ. 

 There are ocellar, outer vertical and postvertical bristles, the outer 

 vertical are the smallest; on the ocellar tubercle are a pair of very 

 small hairs. Eyes large, somewhat oval, narrowed below; the hind 

 margin is slightly curved in downwards. In the living specimens the
