AMERICAN J)IPTERA. . 347 



teres infuscated. Wiugs hrown, narrow, stigma but little darker, veins piceous- 

 brown, marginal cell not widened. 



One male ; Hertford Co., N. Car., June 9, 1895. (C. W. John 

 son). 



In stature this species resembles thoracicus and rufus, but differs 

 conspicuously in the smaller thorax, more elongate abdomen, and 

 different venation. From the smaller species longipennis is at once 

 distinct by its bristly femora and darkened wings.

This is the species given in the New Jersey " List" as stigmatella 

 Zett. The following notes made from the New Jersey specimen 

 may be of service. Antennae two-jointed, the first joint minute, the 

 outer joint large, broad, blunt, equalling the eye-height, the arista 

 minute. Scutellura with four bristles. Legs testaceous. Halteres 

 pale yellow. Stigma very weak, the interstitial vein reaching two- 

 thirds the distance to the margin. Another female differs from the 

 New Jersey specimen in that the wings are nearly clear and the 

 interstitial vein is perfect.

The North American species included in this genus belong more 

 properly with the Empidinne as they are here defined, but they show 

 a transition toward the Hybotinse in that the thorax is greatly 

 arched, the anal cross vein is not so strongly inclined as usually is
