1920. Lundbk. Vidensk. Meddel, fra Dansk naturh. Foren. 71, 22, 25. 

 — 1920. Schniitz, Jaarb. Natuurh. Genootsch. Limburg 1919, 147. 



Male. Frons considerably broader than high, grey; inner bristle 

 of lower row below the oiiter, rather close to it and somewhat near 

 to the margin; supraantennal bristles imequal, the lower less than 

 half as large as the upper; the iipper supraantennals fiilly as distant 

 as the inner bristles of middle row, the lower a little more approximate. 

 Antennæ not small, brownish black, arista somewhat short, distinctly 

 pubescent. Palpi yellow, not large and with the bristles somewhat short. 

 Thorax black, very slightly shining, almost dull, with brown pube- 

 scence. Mesopleura bare. Abdomen deep black, dull; hairs almost 

 invisible, only longer and more distinct on sixth segment, especially 

 at the hind margin. Hypopygium quite small and retracted, though a 

 subanal body is exposed in the shape of a downwards protruding 

 process; ventral plate broad, but short, yellow; anal tube somewhat 

 small, but of medium length, yellow. Legs yellow, hind femora slightly 

 brownish yellow, the hairs below the basal half long; front tarsi 

 with the three first joints a little stout; bristles on hind tibiæ distinct, 

 but somewhat small. Wings a little yellowish, veins brown; costa 

 reaching nearly or quite to the middle, costal divisions about as 

 10 — 6 — 3; costal cilia short or moderately short; fourth vein evenly 

 curved. Halteres black. 



Female. Unknown. 



Length. About 1,3 mm. 



A. griseifrons seems to be rare; Holte ^Ve 1919 (Th. Mortensen) 

 and Ry in Jutland ^7? 1918 (the author), two males. 



Geographical distribution: — Hitherto only known from Denmark. 



Remarks: On account of the shape of the front tarsi this species 

 must be similar to anisodactyla Schmitz with which it also in other 

 respects seems to be conform, but anisodactyla has yellow halteres.
