Legs wholly yellowish, except the blackish coxae. The middle femora and tibiae are distinctly longer than the fore pair, and the hind pair are proportionately longer than the middle pair. Tarsi long; the anterior ones about equal in length, but the hind pair are distinctly longer, proportionately. The tibiae end in a well- developed (almost Bibio-\ike) blunt spine on the front side, with a smaller one (easily seen on the hind legs only) on the inner side. The pulvilli, three in number, elongate, very greatly developed;. Fig. 12.—Pterodontia dorsolineata, Brim., wing. the claws very long and strong, curved. Wings colourless, veins yellow, venation normal; upper squamae quite small, nearly circular, lower pair very large, with a short yellow fringe, both practically colourless ; halteres black.
