Dipfera of St. Vincent {West Indies). 295 



Basal half of the femora yellow ; the distal part with two dark- 

 brown bands, and two, narrower, yellow bands, the second yellow 

 band at the tip ; tibiae and tarsi brownish, with a narrow yellow 

 band at the base of the tibia? (middle and front legs wanting). 

 Wings with uuiform brown spots, located as in the figure ; sepa- 

 rated from the infuscation of the rest of the wing by narrow, 

 hyaline, or light-yello ^ margins. Length 7 mm. 



One specimen. 1500 feet. 



Tjpula.

(^ . 9 • Antennas black, or black and yellow ; wings uniformly 

 subinfuscated. Length 12 mm. 



Antennae in the male black, the proximal three or four joints 

 yellow, about as long as the front femora ; in the female, yellow, 

 with the proximal end of the sixth and following joints black, and 

 only about as long as the mesonotum. Thorax light yellow, the 

 mesonotum brownish. Front, rostrum and palpi yellow, the last a 

 little brownish at the tip. Halteres brown. Abdomen reddish- 

 yellow, the lateral margins of all the segments, a part of the sixth 

 segment, and all of the seventh, black (in the female specimen the 

 abdomen is wanting). Legs yellow, the tip of the tibioe, and the 

 tarsi for the greater part, black. Wings uniformly tinged with 

 brown, the costal cell and the stigma pale brown. 



I can find no description whicli will apply to this 

 species, though that of T. infuscata, Loew, will nearly 

 do so. The colour of the antenuoe in the female will a,t 

 once distinguish the two.
