Sarcophaga.

taken in copula. It may not rarely be seen on human excrements; 

 it is, however, also recorded as bred from Lymantria monacha 

 (Kramer). 



Geographical distribution: — Distributed at least over all 

 Europe, but its records from North America have been shown 

 erroneous. 



Remarks: Zetterstedt records albiceps from Denmark, but albi- 

 ceps in Stægers collection is carnaria.

Male. Tilis species is highly similar to carnaria and almost 

 only distinguished on the genitalia. Frons scarcely half as broad as 

 the eye (but a little varying). Fourth sternite with a little longer 

 hairs than in carnaria^ and the hairs erect. Upper forceps quite or 

 nearly quite straight, with the ventral apical 

 ineision a little deeper and narrower than in 

 carnaria; anterior claspers not or almost not 

 longer than posterior, and less dilated apically, 

 the posterior not pointed. Penis with upper lobe 

 small and narrow, lower lobe large, united with 

 the end piece of penis; the transverse end shorter 

 and less angularly bent than in carnaria. 



Female (in copula). Quite similar to the 

 female of carnaria and at present scarcely to 

 be known from it; frons perhaps a little narrower, 

 as broad as the eye. 



Length 10 — 15 mm. 



Remarks: Resides by the genital characters 

 the male may be known by the hairiness of fourth sternite, a char- 

 acter which Rottcher has not observed. 



S. vicina does not seem to be common in Denmark; Copenhagen 

 in a garden, Hellerup, Geel Skov, Ridstrup Hegn, Jyderup, on Lol- 

 land at Nysted and in Jutland at Kliplev and Skanderborg (the 

 author); the dates are ^7 5 — ^U'i I took it in copula on ^/g and ^/g. 



Geographical distribution: — The species seems to be distributed 

 over all Europe; towards the north it is known from Finland.
