Face and front dark metallic green; front dulled with blackish-brown pollen, slightly over twice as wide as high; face narrowed below, eyes essentially continguous in lower half; anterior eye facets somewhat enlarged. Palpus and proboscis dark. Antenna black, segment 3 blunt, arista nearly half again as long as face.

Thorax metallic dark green above, a little more brownish on pleura, with slight pollen; setae yellowish brown; about 6 pairs of small acrostichals; 6 or rarely 7 pairs of dorsocentrals, only hind pairs rather long; scutellum hind margin rather sharply rounded in middle or evenly rounded, bristles usually slightly nearer middle than sides.

Legs yellowish brown with trochanters, most of forecoxa, and sometimes most of forefemur rather pale; setae mostly dark. Fore- and middle coxae with numerous pale hairs anteriorly; fore- and middle femora with only small setae, sometimes a weak erect pale seta below near base of middle femur; hind femur with a few longer setae anteroventrally toward tip; middle tibia with small but distinct seta near distal third; hind tibia with small dorsal setae near base, distal third, and tip. Foretarsus (Figure 218) with segments 1 and 2 compressed, 3 cylindrical with a cushion of setae anteriorly near base and a small stout seta posteroventrally near tip, lengths of segments from base as 5-2-4-2-3; middle tarsus as 6-4-3-3-3; hind tarsus as 6-7-5-4-4.

Wing (Figure 221) oval, with evenly curved hind margin, anal angle not prominent, wing surface slightly brownish tinged or clear, veins brown; vein 2 slightly but evenly arched, curved distinctly forward at tip; veins 3 and 4 nearly straight, diverging from near base; crossvein nearly perpendicular to vein 4, about as long as last of vein 5; vein 6 represented by slight fold lying near anal margin. Knob of halter blackish.

Abdomen (Figure 219) slightly longer than thorax, cylindrical, slightly compressed, covered above with dull brownish pollen, rather translucent on sides, with short dark setae; sternites without auxiliary genitalia. Hypopygium small, capping tip of preabdomen, brown, bearing a pair of narrow rather truncate pale brown lamellae (Figure 220), each lamella with a few long whitish marginal setae mostly near tip; inner appendages slender, pale brownish.

FEMALE.—Similar to male, with lower face as wide as antennal segment 1; middle femur without erect seta near base; foretarsus plain; abdomen slightly flattened.
