1G0 DIPTERA OF NORTH AMERICA. [PART III. 



sides ; the pleura? likewise are rather shining. The anterior part 

 of the abdomen of a metallic dark-violet hue; the apical half 

 yellow, sometimes with a dark stripe in the middle. The first 

 segment of the very much flattened ovipositor rather broad and 

 long, black, usually with a bronze reflection. Feet black, only 

 the extreme tip of the femora reddish-brown and the basis of all 

 the tarsi brick-red. Halteres yellowish, the stem usually infus- 

 cated. Wings hyaline, with four black spots on the anterior 

 margin ; the first among these spots, placed on and immediately 

 beyond the humeral crossvein, extends as far as the basis of the 

 anal cell, so that the extreme root of the wing itself is hyaline ; 

 the second spot, covering the tip of the costal cell and the very 

 short stigma, with the exception of its extreme end, runs perpen- 

 dicularly and preserves the same breadth, as far down as the 

 fourth longitudinal vein, beyond which it is still perceptible as 

 a blackish-gray shadow ; the third black spot lies opposite the 

 posterior crossvein, is of an elongated triangular shape, and 

 reaches with its tip as far as midway between the third and 

 fourth longitudinal veins, the fourth spot has an irregularly 

 rounded shape and lies quite near the apex of the wing ; it 

 covers the extreme end of the marginal cell and the end of the 

 submarginal with the exception of its extreme tip ; on its poste- 

 rior side (that is the side which is nearer the basis of the wing) 

 it crosses the third longitudinal vein ; the last section of the 

 fourth longitudinal vein, which is distinctly, although not strongly, 

 curved, converges in its whole course towards the third longitu- 

 dinal vein, without approaching it more, however, than in the 

 several preceding species.
