 the scutellum, the pleurae in part, femora in part, knob of haltercs, 

 and tip of abdomen somewhat lighter coloured or brown. The 

 tibife in part, and the tarsi, yellow or yellowish. Antenna; black, 

 stout, the joints closely united, and gradually increasing in width 

 to very near the tip. Wings greyish hyaline, the anterior 

 thickened veins dark brown, the others light yellowish ; the short 

 veins do not reach nearly to the middle of the wing ; the short 

 prefarca of the forked cell takes its origin nearly opposite the 

 connecting cross-vein of the subcostal cell ; the branches of the 

 forked cell are very long and strongly curved away from each 

 other near the margin of the wing. Length 2 mm. 



One specimen. Loew's description agrees well with 

 this specimen, still, the identity cannot be positively 

 stated without comparison of specimens from the United 

 States.
