Sarcophaga. 193 



ventral horn; the two apophyses are curved towards each other, to- 

 gether forming a ring; above them a lobe is seen with a triangiilar, 

 pointed and upwards directed tooth on each side. Posterior femora 

 densely fringed below; hind tibiæ with long and dense antero- and 

 posteroventral fringes, and also middle tibiæ more or less fringed 

 on both sides; middle femora with a comb but without posteroventral 

 bristles basally; hind femora with an anteroventral row of more or 

 less distant bristles in apical half or more. Wings nearly hyaline; 

 costal segment 3 rather longer than 5; subcostal vein bare; no 

 costal spine. 



Female. I have not seen the female; according to Bottcher it 

 has the frons about as broad as the eye and will be easily known by 

 the shape of sixth abdominal segment which is triangular and pro- 

 truding, divided into two halves by a split which is narrow on dorsal 

 side, broader ventrally; the margins of the split have hairs both 

 above and below but only apically, whereas they are nearly bare 

 forwards. 



Length 11 — 16 mm (after Bottcher 8 — 20 mm). 



S.scoparia seems common in Denmark; Lyngby Mose, Geel 

 Skov, Jyderup and in Jutland at Skanderborg and Hattenæs near 

 Silkeborg; the dates are ^^/j — ^^/g. 



Geographical distribution: — All Europe and in Turkestan; 

 towards the north to southern Sweden (Ringdahl). Kramer thinks 

 it occasionally parasitic on Ly mantria monacha. A variety is recorded 

 from North America.

Male. Frons fully half as broad as the eye, orbits fully half 

 as broad as frontal stripe. Orbits and cheeks generally yellowish, but 

 also often white, silvery, dark reflecting. Jowls likewise yellowish 

 to grey; frontal stripe black. No or small outer vertical bristles. 

 Bristles on cheeks somewhat long, not distinctly in one row. Fine 

 vibrissæ produced to or near to the middle. Jowls black-haired.
