LABIA. 115 Proreus simulans and P. hulelcingi, and also, as de Bormans suggested from the description, Apterygida erythrocepTiala-, it also recalls Elaunon bipartitus. For this reason it is important to examine the tarsi, as the simple cylindrical second segment will at once remove all idea of its identity with any of the above-named species. Perhaps the doubtful Apterygida cingalensis, Dohrn, should be referred here. Genus LABIA, Leach. Labia, Leach, (15) p. 118. Copiscelis, Fieb.

Antennae with 10-15 segments ; the first long and pear-shaped, the second very small, the third long, almost as long as the first, fourth nearly or quite as long as the third, the rest gradually lengthening, cylindrical or cylindro-conical. Pi'onotum as broad as the head. Elytra always, wings usually well developed; former with no keel. First tarsal segment hardly longer than the third, the second very small; the tarsi.

Last dorsal segment transverse. Penultimate ventral segment rounded in both sexes. Pygidium prominent or concealed. Forceps various, but generally remote at the base in the (S, elongate or short, nearly straight or strongly curved, unarmed or toothed; in the $ simple, short, straight. Range. Cosmopolitan. About fifty species, from all parts of the world, are at present included in this genus ; but it requires subdivision, and some members at least will be removed to other groups. A good many species are unrecognizable owing to insufficient description. i2.
