Male. Frons a little higher than broad, or about qiiadratic; it 

 is greyish black, somewhat shining; the middle row of bristles placed 

 rather high as in gregaria^ and so also the outer bristle of the lower 

 row, and thus the inner bristle much below the outer, and it is placed 

 nearly in the middle between the eye-margin and the upper supra- 

 antennal; supraantennal bristles nearly equal, the upper not approxi- 

 mate, a little more distant than the inner bristles of middle row, 

 the lower a little more approximate. Antennæ somewhat small, black, 

 arista somewhat short, distinctly, but short-pubescent. Palpi brown- 

 ish or blackish, well developed and with well developed bristles. 

 Thorax black, somewhat shining, with blackish brown pubescence. 

 Mesopleura bare. Abdomen black, slightly greyish, dull; the very 

 short hairs only just visible at the hind margins of the segments. 

 Hypopygium small, only with some small hairs on the sides; below 

 two claw-like processes are seen, one on each side, directed back- 

 wards; anal tube not short, but quite slender, blackish brown. Legs 

 black, front legs almost not paler; hind femora with the hairs below 

 the basal half a little longish; bristles on hind tibiæ small, but distinct. 

 Wings somewhat yellowish or slightly brownish tinged, veins brown; 

 costa about 0,36 of the wing-length, it is distinctly thickened from the 

 apex of first vein to the end; costal divisions about as 3 — 1 — 1; 

 costal cilia very short and rather fme ; fourth vein slightly and evenly 

 curved and a little recurved at the apex. Halteres black.
