Palpus and proboscis yellowish brown. Antenna black, segment 3 blunt, arista slightly longer than face.

Thorax metallic dark green with very slight pollen, pollen more yellowish above; setae dark; about 6 pairs of small acrostichals; 6 or 7 pairs of equally small dorsocentrals, last pair rather long; scutellum hind margin evenly rounded, bristles slightly nearer middle than sides.

Legs mostly brown with trochanters slightly paler, tarsi black; setae mostly dark. Forecoxa with only short hairs; forefemur bare below except a short but slender erect seta near base; middle femur with setae longer anteroventrally near tip; hind femur (Figure 61) with a distinct tooth or spur at about distal one-third of lower margin directed anteroventrally, a row of rather strong anteroventral setae along length of the femur, 4 or 5 distinct before spur, a few erect anterodorsals near base; tibiae, especially fore and hind appearing rather stout, without distinctive setae; middle tibia with a long posterodorsal just before middle; hind tibia with slightly longer anterodorsal near base and tip.
