lialf (one of them not rarely wanting, generally, however, only on 

 one leg), and with five to seven dorsal bristles; hind tibiæ with one 

 anterior bristle below ttie base. Wings somewhat strongly brown, 

 veins dark brown, costa black, reaching about to the middle, 0,48 — 0,49 

 of the wing-length, 1 a little shorter than 2 (about 17 — 20); costal 

 cilia long; fourth vein evenly curved, only slightly more in the first 

 part; seventh vein relatively distinct, reaching the margin. 



Female. Unknown. 



Length 2,4—2,7 mm. 



Ph. artijrons is rare in Denmark, we have only three specimens, 

 all males, two taken by Stæger, they are without particular locality, 

 but are probably from the vicinity of Copenhagen, and one from 

 Teglstrup Hegn (Schlick); the latter is taken on ^"/s; the two spec- 

 imens from Stæger stood determined as velutina and one of the spec- 

 imens is labelled "Zett. det.", and is mentioned by Zetterstedt Dipt. 

 Scand. VII, 2893, so that artijrons is identical with Zetterstedt's 

 velutina or included in it. I have compared my specimens with a 

 typical specimen from Pater Schmitz. 



Geographical distribution: — Besides from Denmark known from 

 various piaces in Germany.

Male. Frons rather narrow, of equal breadth in the whole length; 

 the hairs short, few in number and only present just on the front 

 part, the third row of bristles convex, the inner bristles only half as 

 large as the outer. Thorax with the hairs somewhat long and dense. 

 Hypopygium with the left arm of forceps without fissure and thus 

 not divided into two lobes, it is shining and distinctly hairy on the 

 lower part; the right arm is somewhat large with the hinder corners 

 drawn out and somewhat incised in the hind margin; the process 

 on the left side of the ventral part of the hypopygium is furcated 

 (according to Schmitz, it was not to be seen on my specimens). Legs 

 black, front legs with knees and tibiæ yellowish, and also front tarsi 

 and to a less degree middle tarsi paler; front tarsi very slightly or 

 almost not dilated, fourth joint considerably longer than broad and 

 as long or fully as long as the fifth; the basal process on hind femora
