372 Orthorrhapha brachycera. 



the cubital vein curved upwards at the apex so tliat the first posterior 

 cell is widened lowards the end; the discai vein straight. Squamulæ 

 yellowish, with a dark fringe. Halteres yellow. 



Female. I do not know the female; according to the descriptions 

 it has the eyes separated by the epistoma, but this is very narrow 

 above; the wings of usual shape, with the discai and cubital veins 

 almost parallel, and the wings less brown than in the male. 



Length about 1,4 mm. 



E. alpinus is very rare in Denmark, we have only one specimen, 

 a male, taken on Læsø in July 1884 (H. J. Hansen). 



Geographical distribution : — Northern and middle Europe down 

 into Austria; towards the north to northern Sweden. It was first 

 detected in England. — For the rest I am not sure with regard to 

 the southern distribution of this species, and perhaps it is not known 

 south of Denmark and England; the Kat. palåarkt. Dipt. says "Europa 

 centr, et sept." I think that Europa centr, is caused by Mik's men- 

 tion of the species, but he does not say from where he had it. 



27. TeucIiopliOPUS Loew. 



Species of very small size and of green colour. Head about of 

 the breadth of thorax, slightly arched behind. Vertex almost not ex- 

 cavated. Frons broad, decreasing in breadth towards the antennæ; 

 ocellar, outer vertical and postvertical bristles present, and besides a 

 pair of not quite small bristles on the posterior side of the ocellar 

 tubercle. Eyes large, separated in both sexes, but near to each other 

 below at the end of the epistoma, nearest in the male; they are 

 hairy. The facets seem to a be a little enlarged on the front part. 

 The postocular bristles form a single row, and besides there are some 

 bristles on the lower part of the occiput. Antennæ inserted near to 

 each other above the middle; they are short, of the same or about 

 the same shape in both sexes; the second joint simple, the third 

 short, not longer than broad, triangularly roundish or almost reniform; 

 arista dorsal, its fn-st joint not quite short. The basal antennal joint is 

 bare, the second has bristles at the apex, the third and the arista are 

 distinctly haired. Epistoma a little broad above, but narrowed down- 

 wards, especially in the males and in this sex very narrow below; 

 the clypeus is separated by a slight, transverse ridge; it does not at 

 all reach the lower margin of the eyes. Proboscis not or almost not' 

 protruding; it and the oral aperture somewhat larger in the female 

 than in the male. Thorax rectangular, high, and arched above; post- 

 scutellum rather large with an impressed line at each side; pro- and
