Fig. 28. Wing of D. trivialis cf. 



Female. Epistoma somewhat broader than in the male, greyish 

 white. Antennæ a little shorter, the third joint not longer than broad ; 

 the second joint often more yellow than in the male, and often the 

 third joint slightly reddish below at the base. Front tarsi without 

 erect hairs and hind femora without fringe. Wings a little darker, 

 without costal swelling. 



Length 4 — 4,5 mm. 



This species is in the female somewhat similar to confusus, which 

 also has a bristle above on the middle metatarsi, but it is distinguished 

 by the longer first antennal joint, the quite yellow front coxæ, the 

 mainly black front tarsi, which in confusus have only the last joint 

 black, and tinally by the hind tibiæ not or snghtly darkened at the apex. 



D. trivialis is not rare in Denmark; Amager, Vester Fælled, Ordrup 

 Mose, Dyrehaven, Vedbæk, Faxe Ladeplads; on Funen at Veflinge, 

 and on Fænø; in Jutland at Frijsenborg and Frederikshavn, and on 

 Bornholm at Allinge. My dates are ^^le—^ls. It occurs at water and 

 on humid piaces in woods, but I have especially taken it near the 

 coast in low herbage. 



Geographical distribution : — Northern and middle Europe down 

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