In addition to the characters listed as generic, the species shows the fol- 

 lowing ( in both sexes unless the contrary is indicated) : General color 

 brown-gray, pollinose ; front red in middle, yellow toward antennas, brown 

 at vertex ; a circle of pale pollen, interrupted behind, around the ocellar 

 prominence ; gena and bucca brown in ground color ; palpi yellow ; tips 

 brownish; proboscis blackish; antennse black, second joint sometimes 

 brown, over half as long as third ; arista straight, short, thickened for 

 2-5 its length. Thorax indistinctly brown above ; humerus dark brown on 

 the side, below which the pollen suddenly becomes whitish, making a pale 

 spot which includes the lower half of the spiracle ; mesopleura hairy on less 

 than the upper-posterior half; calypters pale yellow, rim and its hairs the 

 same ; halteres yellow. 



Abdomen tessellated, opaque brown-gray ; in the male the first segment 

 is longest, in the female the fourth ; the male has a small and retracted 

 hypopygium, the fifth sternite with a broad emargination behind and a 

 narrow lobe each side. Coxje, femora, and tarsi black, the trochanters and 

 tibiae yellow; front tibi?e with two small set^e on outer hind side; middle 

 tibia with one on outer front, three small on outer hind side ; hind femur 

 with an upper-outer row of bristles double toward tip, and a sparse row 

 below that begins about the middle ; in the male there is at base below 

 a protuberance against which the tip of the tibia closes, which bears a 

 bunch of black spines. Hind tibia with the row behind as already men- 

 tioned, three on outer hind side, four on outer front side. Hind basitarsus 

 with spine below. Pulvilli short, the front ones a little elongated in the male. 



Wing hyaline or very slightly grayish, veins brown to yellow ; setul?e 

 on costa beginning before the tip of auxiliary and extending nearly to 

 tip of second, but not very large. 



Length 5 to 5^ mm.
