mixed ; tlie marginal bristles of the thorax are stouter and likewise the two on 

 the scutellum. The spur of the hind tibiae is much reduced. The third and 

 fourth longitudinal veins are straight and diverge but very slightly; the first 

 basal cell is three-fourths as long as the second. Length 1.5 mm. 



A single male ; Battle Creek, Michigan (J. M. Aldrieh).

Drapetis xanthopodus Williston. 



A specimen from Georgia very closely resembles the type from 

 the Island of St. Vincent, West Indies. The thorax is less bril- 

 liant, however, and the legs are more dusky. 



One specimen ; Galveston, Texas. 



In this connection may be noted a slip of the pen in the appendix 

 to Dr. Williston's "Diptera of St. Vincent." Xcmthopodus is there 

 called ftavipes, its manuscript name (not flavipes of Macquart), and 

 fiavidus is called xanthopodus.
