128 Orthorrhapha brachycera. 



and a postalar bristle, all black; besides there are some hairs on the 

 sides of the disc. Scutellum with four black marginal bristles. Pleura 

 grey, metapleura with black, propleura with some pale hairs. Ab- 

 domen slate-grey, clothed with short, black, at the base with some- 

 what pale hairs; venter similarly coloured and haired. The lamellæ 

 of the ovipositor somewhat long and thin. Legs black ; coxæ greyish 

 pruinose, and the legs also on the whole somewhat pruinose. They are 

 short-haired, the front and middle tibiæ with a row of fine hairs 

 above, most distinct on the front tibiæ; hind tibiæ with some fine 

 bristles above, and hind femora with a row of fine hairs below. 

 Wings hyaline, very slightly greyish; veins brown, costa and the 

 €ubital vein blackish; the lower branch of the cubital fork bending 

 slightly downwards, terminating at the apex of the wing. Stigma 

 faint. Halteres whitish.

The species was founded by Zetterstedt on females, and I also 

 have only females, the male thus not being known. I have not seen 

 the type, but I think the determination beyond doubt as Zetterstedt's 

 description quite agrees. 



E. cinerea is at present only very little known, I caught all my 

 specimens, nine in number, with the net on a common on Amager 

 in the grass, on ^/i; — ^Wo 1909. The locality is similar to that men- 

 tioned by Zetterstedt; „In Oelandia ... in floribus Potentillæ . . . juxta 

 litus maris . . .". 



Geographical distribution : — Middle Sweden to Denmark. 



Remarks: I think this species may belong to Pterempis, though 

 its legs are not pennate. 



VII. Subg. Empis s. str. 

 Somewhat large or medium-sized species, generally of brownish 

 or greyish colour, sometimes somewhat lighter. Eyes contiguous in 

 the male, with the upper facets larger than the lower; separated in 

 the female. Antennæ as a rule somewhat long, the first joint gener- 

 ally about twice as long as the second, sometimes only slightly longer; 

 the third joint generally elongated. The dorsocentral bristles pluri- 

 serial (only in livida uniserial), the acrostichal bristles pluriserial or 

 biserial; the sides of the disc with hairs, sometimes somewhat fused 

 with the dorsocentral hairs. There is a humeral bristle, only rarely 

 absent (borealis), further one or three posthumeral bristles (absent in 

 horealis and opaca), three to several notopleural, one supraalar and 

 one postalar bristle. Metapleural bristles numerous; propleura with 

 distinct hairs. Scutellum with four to several marginal bristles. Ab-
