Of this species I know only the female. Frons above about as 

 broad as the eye, somewhat protruding. Cheeks broad, a little narrow- 

 ing downwards; jowls about one third of the height of the eye. Orbits 

 and upper part of cheeks grey or yellowish, cheeks for the rest, and 

 jowls silvery whitish grey; frontal stripe velvet black or blackish 

 brown. Frontal bristles descending fully to insertion of arista. Vi- 

 brissæ not ascending above one third of the height, the angular 

 vibrissa strong. Orbits and jowls with black hairs, but very sparingly. 

 Occiput somewhat convex and pufTed out below and the eye-margin 

 broadened downwards; occiput grey with whitish hairs, and black 

 hairs behind postocular bristles. Antennæ black, third joint about 

 thrice as iong as second; arista long, thickened in about basal third, 

 second joint distinct but not elongated. Palpi yellow, a little dark 

 at base, dilated outwards. Thorax greyish black, grey pruinose with 

 four dark stripes, the median abbreviated behind, the lateral divided 

 at the suture into two elongated spots ; scutellum dark, grey pruinose. 

 Thorax black-haired ; three postsutural dorsocentrals and two or 

 three præ- and three postsutural acrostichals. Scutellum with three 

 strong marginal bristles on each side, apical bristles wanting. Three 

 sternopleural bristles. Abdomen blackish, the three last segments 

 greyish pruinose, shifting with irregular brownish tessellations 

 according to view; a somewhat indistinct middle line and narrow 

 hind margins blackish; excavation on second segment not quite 

 reaching hind margin; abdomen with somewhat strong black hairs, 

 second segment with a pair of marginal bristles, third with one or two 

 pairs of discai and a pair of marginal and fourth likewise with one 

 or two pairs of discai and with a row of marginal bristles ; all bristles 

 strong. Legs black with strong bristles. Wings brownish tinged; 

 veins brown; discai angle obtuse; apical cross-vein sloping and 

 slightly concave; first posterior celi open, ending rather near apex of 

 wing. Squamulæ white. Haiteres yellow. 



Length. About 9 mm. 



I have examined Zetterstedt's type, it is a female as also seen 

 of the description.
