black bristles near the tip on tbe lower outer edge; hind pair slightly 

 darkened above at tip ; fore tibiae brown with three bristles below, 

 close to the tip; middle and hind tibiae black; fore and middle tarsi 

 yellow with all the joints black at the tip; hind tarsi black with the 

 first and second joints equal; pulvilli and empodium well developed. 

 Tegulse, their cilia and the halteres yellow. 



Wings grayish-hyaline, brown in front of the third vein ; fourth and 

 fifth longitudinal veins and the posterior cross-vein bordered with 

 brown; last section of the fourth vein slightly approaching the third 

 at tip ; there is an upward sinus at the center of the last section of 

 the fourth vein. 



Female : Agrees with the male in all but sexual characters, ex- 

 cept that the palpi are blackish, with white pollen and yellow edges, 

 and the thorax is more thickly covered with pollen. There are six 

 dorsocentral, one large and one small humeral, a post-humeral, one 

 notopleural, two supraalar and one postalar bristles, also one or two 

 small presutural bristles; on the prothorax there is a transverse row 

 of yellowish bristles, those near the fore coxae large, but those on the 

 dorsal part of the row small. In the male (which I make the type of 

 the species) all the bristles are missing from the mesonotum and 

 scutellum although the specimen is in good condition otherwise. 



Described from one male and one female which I took on a 

 salt-marsh on the Manatee River at Bradentown, Florida, in 

 March.
