or pubescence short, white, longer on the lateral margins and more 

 noticeable on the third and fourth segments. Venter concolorous with 

 the dorsum with the exception of the first segment which is blackish. 



Femora black, shining, with very short and sparsely white pile; 

 apex of femora and trochanters reddish. Tibiae reddish, piceous at 

 their outer ends, covered with short abundant white pile; first joint 

 of hind tarsus considerably enlarged. Wings hyaline with a dark brown- 

 ish cloud in the middle on the anterior half of wing, smaller clouded 

 areas following the veins closing first and second posterior cells and 

 about the marginal and submarginal cells. Veins brown; stigma 

 luteous. A stub of a vein extrudes half way across the first posterior 

 cell at its middle. 



Female: Very similar to the male. All three joints of the antennae 

 light yellowish brown, outer half of last joint grayish or blackish. 

 Arista entirely reddish yellow. Front noticeably wider. The ground 

 color of thorax appears more metallic and greenish. Scutellum more 

 purplish bronze. The second segment lacks the brown triangle and is 

 entirely reddish.

It gives me pleasure to name this species in honor of Mr. 

 R. H. Painter who has been active in the collection of the 

 Syrphid fauna of the region. 



Somula mississippiensis, new species. 



Male: Antennal process extraordinarily long and prominent; the 

 distance from base above to tip being approximately half as long as 

 the distance from the base above to the epistoma or twice the length 

 of the process in Somula decora Macquart; yellow below, entirely black 

 above, the black extending to the eyes, its margins straight. Antennae 

 black; second and third joints covered with microscopic, light colored 

 pubescence; arista yellowish red near base, blackish apically. Face 

 below antennal process only slightly concave and a little convex on 

 lower part; descending perpendicularly considerably below the eyes; 

 shining pale yellow, with a black median stripe extending from the 

 epistoma to half the length of the antennal process on its lower surface. 

 Cheeks shining black. Front black, almost destitute of the rather long, 

 yellow pile that sparsely covers the occiput and the posterior orbits
