yellow colour may be extended somewhat downwards; the apical part

 hind femora with longer hairs above in the basal half, and with short, 

 pale hairs below; middle femora with one, hind femora with two 

 (rarely one) preapical bristles; front tibiæ with bristles above, and 

 generally two postero-ventral bristles; middle tibiæ with about four 

 antero-dorsal, two postero-dorsal, and with one ventral bristle below 

 the middle; hind tibiæ with two dorsal rows of bristles, and one ven- 

 tral bristle towards the apex, besides with a ventral row of small 

 bristles ; hind metatarsi with about three dorsal bristles, some anterior, 

 and with small ventral bristles. Wings more or less brownish tinged, 

 somewhat strongly towards the anterior margin; veins black; discai 

 vein with a not large, obtuse bend; axillary lobe large, anal vein 

 going somewhat downwards. Squamulæ yellow, with a black fringe,

D. urhanus is rare in Denmark and has only been taken at few 

 occasions; Ordrup Mose, Dyrehaven (Stæger), and in Jutland at Funder 

 near Silkeborg (Esben Petersen) and Hald near Viborg (the author). 

 The dates are in June. It has been taken in fens and on humid 

 piaces in woods. 



Geographical distribution: — Northern and middle Europe down 

 into Franco; towards the north to northern Scandinavia, and in Fin- 

 land. It is generally somewhat rare. 



Remarks: In Kat. palåarkt. Dipt. is urhanus given with Stannius 

 as author, and tirbanus Meig. is placed as synonym to simplex Meig. 

 I do not know the reason for this, and I foUow Verrall (Ent. Month. 

 Mag. XV, 1904, 242) and the earlier authors in considering Meigen's 

 urhanus as identical with Stannius' species of the same name.

Of this species I have only examined one single male specimen, 

 Zetterstedt's type-specimen ; it is now in so bad a condition, that a 

 detailed description is impossible, so that for points not mentioned
