Legs yellow, front coxse whitish pruinose anteriorly, and with a little grey spot at the base, posterior coxae grey, with the apical part yellow; hind femora with a black spot above at the apex; anterior tarsi with the apical part of metatarsus and the following joints black; hind tibiae black at the apex and hind tarsi black. The legs have short, black hairs, anterior coxae somewhat white-haired outwards; posterior femora with one preapical bristle; front tibiae with bristles above, and one or two on the postero-ventral side; middle tibiae with about four antero- dorsal bristles (one of them more dorsal), two postero-dorsal, and one ventral below the middle; hind tibiae with two dorsal rows of bristles, one ventral bristle towards the apex, and a ventral row of small, distantly placed bristles; hind metatarsi with two dorsal, some anterior, and with quite small ventral bristles. Wings somewhat blackish or brownish tinged at the anterior margin, especially above the cubital vein, sometimes, namely in fresh sp
