Sarcophaga. 183 



ventrally, in profile with nearly parallel margins, but a little attenuated 

 apically; it is incised in ventral margin above apex so that an apical 

 hook is formed. Anterior claspers longer than posterior, a little 

 curved, not pointed; posterior claspers curved and pointed. Penis 

 with the end part roundly swoln basally and of complicate construc- 

 tion, the end not bent forwards, going out in a straight, longitudinally 

 fissured spine; from the ventral side of the swoln part issues at each 

 side a curved thorn-like apophysis. Legs with posterior femora 

 slightly fringed ventrally; hind tibiæ not fringed, at most with some 

 few hairs on posteroventral side at base; middle femora with a postero- 

 ventral row of bristles, but without comb ; hind femora with an antero- 

 ventral row of long bristles. Wings somewhat tinged; costal segment 

 3 and 5 about equal; subcostal vein bare; a costal spine present. 



Female. The female is not known with certainty. 



Length 4 — 6 mm (after Bottcher 3,5 — 8 mm). 



S. Villeneuvei is rare in Denmark, I know only three specimens, 

 all males, one from Ordrup (Stæger), the other without particular 

 locality. 



Geographical distribution: — Europe down into Italy; towards 

 the north to southern Sweden (Ringdahl).

Male. This species is very similar to Villeneuvei] frons still 

 broader, the orbits narrower. Outer vertical bristles strong and like- 

 wise bristles on cheeks. Third antennal joint about one and a half 

 times as long as second, at most just reaching lower end of the eye. 

 Palpi somewhat slender, a little dilated apically. Three postsutural 

 dorsocentrals; præsutural but no præscutellar acrostichals. Scutellum 

 with Crossing apical bristles. Third abdominal segment with strong 

 marginal bristles. Sternites with erect hairs; fifth sternite without 

 brush. Genitalia small; præhypopygiai segment black, without 

 marginal bristles. Hypopygium roundish, black. Upper forceps about 

 as in Villeneuvei^ but the ventral excision before apex deeper. Glaspers
