tral strip on-apical half of first costal cell, a very small and obscure anterior area just beyond base of each of basal cells and of anal cell, and a narrow strip in front of basal third of axillary vein. Squamae, squamal fringe and haltere dull yellow. Legs dull yellow; hind femur and tibia narrowly and obscurely brownish medially, hind tarsi brown towards apex. Leg hairs mostly yellow; anterior and dorsal hairs of apical half of hind femur and of hind tibia, and dorsal hairs of hind tarsus, mostly brown to black. Fore and mid femora at about t their length, and hind femur at about! its length, with a slight but sudden upward bend, the femora at the bend with an apparent weakened area; hind tibia at mid length with a similar downward bend (these bends and weakened areas are probably developmental aberrations).

Abdomen (fig. 3a) rather short, nearly parallel-sided. Tergites dull yellow with blackishbrown markings as follows: all of tergite 1 except lateral angles (tergite apparently slightly deformed); large basal triangle, narrow posterior band and very narrow entire lateral margins of tergite 2, the basal triangle produced caudad to meet the apical band; isolated subtriangular subbasal band, narrow posterior margin and very narrow entire lateral margin of tergite 3, the dark margin produced triangularly mediad opposite the subbasal band; a very narrow isolated subbasal band, a narrow preapical band which is elongated medially and laterally, and very narrow lateral margin of tergite 4; the dark margin produced triangularly mediad opposite the subbasal band and ending slightly before the anterior margin of the tergite; an oval median spot on tergite 5. Sternites 1 to 7 yellow, sternite 8 black. Sternites, tergite 1, all but apex of tergite 2, and large lateral triangles on tergite 3 yellow-haired; rest of tergites black-haired. Longest hairs of tergite 2 only t as long as width of tergite. Terminalia (fig. 3b, c): Surstylus broad with broadest surface directed laterad, slightly and evenly tapering to broadly rounded apex. Sternite 9 with posteroventral emargination about 0,95 times as long as sternite. Superior lobe with apical tooth pale, situated near posteroventral angle of lobe.
