260 Orthorrhapha brachycera. 



pruinose; femora black, the anterior femora with the apex yellow; 

 anterior tibiæ yellow; hind tibiæ compressed and dilated in the apical 

 half, and furrowed on both sides (perhaps due to exsiccation), whitish 

 yellow on the basal half, with the very base dark; anterior tarsi yel- 

 lowish, dark towards the end, hind tarsi black. Middle coxæ with a 

 black apical spine, less strong than in spinicoxa; front and middle 

 tarsi with metatarsus scarcely as long as the three next joints, hind 

 metatarsus about of the length of the second joint. The legs have 

 short, black hairs; femora mainly short-haired, only the front femora 

 with longer hairs on the posterior side ; middle femora with a pair of 

 preapical bristles on both sides; tibiæ with two dorsal rows of some- 

 what long bristles, and middle tibiæ with one ventral bristle; middle 

 metatarsi with a pair of long bristles below at the apex. Wings a 

 little brownish; veins black, discai vein with a small, even curve. 

 Squamulæ yellow, with a blackish brown fringe. Balteres yellow. 



Female. Of more æneous or olive colour, the stripes on thorax 

 more distinct. Frons brownish pruinose. Epistoma broad, this and 

 the large palpi brownish grey. Postocular hairs whitish below. Antennæ 

 shorter than the head, the third joint scarcely as long as the two basal; 

 arista longer than the antennæ. Legs paler than in the male, femora 

 yellowish to brownish or blackish, hind femora blackish at the apex, 

 often only above; hind tibiæ a little compressed and dilated, coloured 

 as in the male; coxæ pale-haired, front coxæ with a few black hairs 

 at the apex, middle coxæ without spine, but with a few black hairs 

 at the apex; middle metatarsi with no long bristles below; front 

 metatarsus scarcely as long as the three following joints. Wings a 

 little more tinged than in the male. Squamular fringe yellow. 



Length 3,6 to fuUy 4 mm. 



The female of this species varies in the colour of the legs from 

 rather pale to about as in the male, but the hind femora are always 

 pale at the base; it is easily known by the hind tibiæ, which are a 

 little compressed and coloured as in the male. 



P. fascipes is rare in Denmark and has only been taken in 

 earlier time; Amager (Stæger); in Jutland at Holstebro (Jacobsen) 

 and at Skagen. I know no time for its captare. 



Geographical distribution: — Europe down into Spain, and in 

 Asia Minor; towards the north to northern Sweden, and in Finland.
