34 Platypezidae. 



on second joint. Postocular cilia somewhat long and strong. Thorax 

 grev or brownish grev, with a broad brown middle stripe, some- 

 times divided along middle, attenuating behind, and two less distinct, 

 abbreviated stripes, one at each side; dorsocentral rows pluriserial 

 as in male. Abdomen bright grey, first segment black on middle, 

 the three following segments with a black hindmarginal band, triangu- 

 larly produced in the middle and thus more or less continuous along 

 the middle; abdomen with short hairs, sixth and seventh segment 

 with ventral bristles. Legs a little paler than in male; hind tarsi 

 similarly, but more, dilated, second joint shorter and quite short 

 below, and metatarsus with some small bristles below at apex; the 

 legs short-haired. Wings colourless or nearly. Halteres yellow. 



Length 4 — 4,5 mm. 



P.fasciata seems somewhat rare in Denmark; Charlottenlund 

 (Schlick) and Geel Skov (the author); the dates are ^/g — -^^/g; two 

 specimens are bred from fungi taken on ^/i2 (Schlick). Zetterstedt 

 records it as early as '^j^. 



Geographical distribution : — Northern and middle Europe down 

 into France and Italy; towards the north to southern Sweden, and 

 in Finland. 



Remarks: As seen my description of the female is more agreeing 

 with Verrall's description of hirticeps than of jasciata\ I have, however, 

 no doubt that my males and females belong to the same species, 

 and this has made me doubt whether hirticeps is really a valid species. 

 Possibly fasciata and hirticeps are only one species, varying in the 

 dorsocentral hairs being uniseral or pluriserial, in the more or less 

 distinct stripes on thorax in female and in the hairiness of second 

 antennal joint and face in male. Verrall mentions also some varying 

 as regards the dorsocentral hairs.
