78 Orthorrhapha brachycera. 



D. planitarsis is not rare in Denmark, but hitherto however has 

 only been taken in few localities ; Ordrup Mose, Ryget Skov at Farum 

 Sø, Sorø, and in Jutland at Funder near Silkeborg. My dates are only 

 '2/5—2/6; Stæger 1. c. records its from May and again from August; it 

 thus occurs rather early, but seems to have two broods. It occurs 

 on open, humid piaces at the outskirts of woods and in fens in foliage, 

 often on the leaves of alder. 



Geographical distribution : — Northern and middle Europe down 

 into France; towards the north to middle Sweden; and in Finland, 



Remarks: Verrall says (Ent. Month. Mag. XV, 1904, 197) that he 

 cannot trace Kowarz's distinctive character of the female, based upon 

 more than one bristle beneath the middle tibiæ (Wien. ent. Zeitg. III, 

 1884, 54); there is also only one ventral bristle, but two antero- 

 ventral in both sexes, so that I think it is these latter which Kowarz 

 has included.
