Sarcophaga. 187 



in apical half, placed rather ventrally. Wings quite slightly tinged; 

 costal segment 3 longer than 5; subcostal vein bare; no costal spine. 



Female. Frons nearly as broad as the eye. Sixth abdominal 

 segment with a long split which is apical and ventral, the margin 

 with somewhat strong and dense bristles, smaller on ventral side. 



Length 8 — 12 mm. 



Remarks : Bottcher says that there is no comb on middle femora, 

 I find a distinct comb of small, sliort bristles; further he says that 

 hind femora have "langen, kraftigen, dichtstehenden Unterrand- 

 makroch."; I find the bristles not dense and present only in apical 

 half. 



S. aratrix seems to be rare in Denmark, I know only five spec- 

 imens, a male taken at Horsens (H. J. Hansen), and two at Skander- 

 borg (the author), and a male and a female from Hareskov; these 

 latter were bred from a dead Prionus coriarius found in October, 

 the imagines came on ^s (Kryger). The other specimens are taken 

 in July. 



Geographical distribution: — Europe down into Spain and 

 Italy; towards the north to southern Sweden (Ringdahl), and in 

 Finland. Kramer suggests it to be parasitic on Lymantria monacha 

 as it became numerous in districts attacked by this species.
