St. Vincent, W. I., sea level to 1000 feet, May. Four males and 

 four females. The female is lighter and more variable, and has the 

 palpi normal. 



Besides the original specimens from St. Vincent, there are in the 

 material at hand ten specimens of both sexes from the Island of 

 Grenada, W. I. The female of this species is most easily recog- 

 nized by the peculiar curvature of the fifth vein in the wing.

 Thorax reddish brown or black, scutellum with four bristles. Abdomen black, 

 with very narrow yellow bands. Halteres and legs yellow; hind femora dis- 

 tinctly blackened, their tibiae with distinct filiation above. Costal vein reaching 

 slightly beyond the middle of the wing. Tip of first vein very near to the sec-

This European species was first found in North America by Mrs. 

 Slosson, in the White Mountains, New Hampshire. I have seen no 

 American specimens.
