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

 the scutellum. The spur of the hind tibiie 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. Aldricli). 



Drapetis spectabilis sp. nov. (figs. 9, 20). 

 Length 2-2.5 mm. Very similar to xanthopodus Williston, dif- 

 fering as follows : 



spectabilis. .xanthopodus. 



Eyes almost touching just above an- Eyes wholly separated above.

Both species possess a small though well-marked brush of yellow

Five males, seven females ; Woods Holl and Horseneck Beach,

Drapeti!« 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." Xanthopodus is there 

 called fiavipes, its manuscript name (not fiavipes of Macquart), and 

 flavidus is called xanthopodus.
