Sparse black but rather coarse pubescence covers the occiput, front and 

 lower half of cheeks, from which it spreads backward; second joint of 

 antennae scantily pubescent above and bearing a distinct bristle; ouel- 

 lar bristles long, curved forward in a pair; two occipito-orbital and 

 two marginal front bristles stout and reversely curved, arising from 

 black dots; vibrissa single. Eyes nearly round, reddish, vertical di- 

 ameter exceeding the width of cheeks by one-half the distance. 



Scutellum bare, entirely grayish sericegus, bearing the usual bristles. 

 Dorsum of thorax, the abdomen and the legs are clothed with black 

 pubescence which is longeron the anterior femora and strongly fringes 

 the fore and middle coxee. A pair of grayish or inclined to brownish 

 sericeous vittse extends medially on dorsum, and similarly colored 

 effects are also shown latterally under different lights. Dorsal bristles 

 arise from black dots. Mesopleura and pteropleura wholly bare; 

 sternopleura with four black bristles in a row close to the upper edge, 

 the posterior bristle being twice the length of the anterior one, and 

 the two middle ones range in length between; the median space of the 

 sternum is covered with long black hairs. 



Lateral margins of abdomen beyond first segment, and distal margins of 

 all segments, brown, the fourth being scarcely infuscated; hypopygium 

 full rounded, dark brownish. Coxae, trochanters and tips of all the 

 femora dark brownish ; tibiee and tarsi inclined to fuscous brown. 

 Halteres brownish. 



Wings hyaline, except yellowish subcostal cell, which is narrow, veins 

 dark or fuscous brown; costal spines black, rather widely spaced; 

 second and third veins slightly approximated, but apically divergent. 



Length, 6 mm.; wing, 5.5 mm. 



Near iners Meigen, but lacks hairs on the mesopleura, while the third 

 antennal joint is fuscous and color of abdomen is variegated; besides, 

 the tarsal joints of fore legs are not flattened and the spurs of the 

 middle tibiae are almost straight. The bristles of the sternopleura 

 are too distinct to be classed as hairs, hence this specimen could not 

 be placed with crassipes Loew, from which it differs in other features.
