of the segments of the flagellum armed with from two to 

 four stiff hairs. Palpus of four segments ; fourth segment ir- 

 regularly cylindrical, longer than the third ; second about as 

 long as the fourth ; first longest ; all armed with many stiff 

 hairs. Eyes large, rather approximated behind. Legs rather 

 short, fore legs about 13.5 mm. long; middle, 10.5 mm. long; 

 hind, 13.5 mm. long. Last four tarsal segments very slender 

 at their point of attachment with the segment preceding. The 

 last tarsal joint is small, irregular in shape, rather smooth on 

 the outer face; inner face, concave, with slight convexities at 

 each end, the proximal with from six to eight hairs, the distal 

 one with a single conspicuous bristle on each side, the whole 

 inner face being rather finely clothed with hair; at the base of 

 the segment on the outer face, are about four stiff hairs. 

 Penultimate segment generally similar to the fifth in shape and

size, but more thickly covered with stout hairs. Claws long, 

 slender, smooth, those of the posterior legs nearly two-thirds 

 as long as the fifth tarsal segment. 



This genus belongs to the tribe Polymedini (Eriopterini 

 of authors.) It is most similar in venation to Empeda and 

 Goniomyia, which it approaches in the shape of cell R-. It is 

 easily distinguished by the much greater length of subcosta, 

 lack of radial cross-vein, the deflection of Cu^ fusing with AP
