lunate; _metathorax_ truncated; _wings_ with three submarginal cells subequal, or the third the longest, and a fourth slightly commenced, the second receiving the first recurrent nervure near its centre, and the third receiving the second recurrent nervure close to its extremity; _legs_ robust, pilose, the four anterior plantæ with a dense, short, setose brush beneath; the _posterior tibiæ_ triangular, very smooth, and irregularly concave on their external surface, fringed with long pile along its two external edges, and its extremity tipped with a short pecten of stiff setæ; the _plantæ_ elongate and broad, nearly equal, externally shagreened and spinulose, with a longish auriculated process at the external angle of the superior edge, a dense brush of short, stiff hair beneath, and a short pecten of stiff setæ edging its subemarginate extremity; the _claw-joint_ the longest of the four short subsequent joints, and the _claws_ bifid. ABDOMEN ovate or globose, deflected towards its extremity, its base retuse, the last segment triangular, and terminating obtusely. The MALE differs in always being more intensely coloured; in having the _antennæ_ distinctly longer, less distinctly geniculated, the _scape_ shorter, the third joint of the _flagellum_ almost as short as its basal joint, and the fourth as long as the terminal one, which latter two are the longest of all, and the joints from the fourth to the eleventh severally more or less slightly curved.
