82 Orthorrhapha brachycera. 



with about three bristles above and one to three postero-ventral 

 bristles; middle tibiæ with about five antero-dorsal, two dorsal bristles 

 and one ventral below the middle; hind tibiæ somewhat thickened 

 in the whole length, with a dorsal and antero-dorsal row of bristles, 

 and a ventral bristle below the middle, besides a ventral row of 

 small, short bristles, almost forming a ciliation; hind metatarsi with 

 three to four bristles above and some on the anterior side, besides 

 distinctly spinulous below. Wings a little brownish, most towards 

 the anterior margin, and here sometimes rather strongly; veins blackish, 

 costa with a small, but somewhat elongated swelling; discai vein with a 

 small, obtuse bend; axillary lobe well developed, anal vein going 

 somewhat downwards. Squamulæ whitish, with a black fringe, Halteres 

 yellowish white or yellow. 



Female. Epistoma much broader than in the male, grey or whitish 

 grey. Antennæ slightly shorter. Hind tibiæ generally more or less 

 yellowish, except the apical part, but sometimes slightly or not at 

 all; hind femora without fringe. Wings without costal swelling. 



Length 4 — 4,5 mm. 



The pupa has a length of about 5 mm. 



This species is in the female very similar to planitarsis, but is 

 distinguished by the broader epistoma, the short third antennal joint 

 with the more dorsally inserted arista, the yellow hind tibiæ with 

 the small ventral bristles more densely placed, and besides by charac- 

 ters in the bristles of the legs, the middle tibiæ having no antero- 

 ventral bristles. — The species was founded on Danish specimens. 



D. lepidus is somewhat rare in Denmark, Lersø (Stæger), Bølle- 

 mosen, Lyngby Mose, Fure Sø, Frerslev Hegn (the author), Hillerød 

 (Godskesen), and in Jutland at Silkeborg. My dates are '^/o to the 

 first part of August; Stæger records it from the last part of May. It 

 occurs in fens and at the horders of water. 



Geographical distribution: — Northern and middle Europe down into 

 France; towards thenorth to northernmost Scandinavia, and in Finland.
