The female is easily recognised by the analogous characters of abdomen, by the large, light-coloured pterostigma and conspicuously brownish tips of wings, as well as by the lateral abdominal blackish lines a little distant from the lateral carinae, and thus producing a pattern of marginal lunules, somewhat similar to the European 0. cancellatum. Not a common species, but very widely distributed in Eastern Africa from Egypt (Cairo) to Natal, and also found in West African stations (Sierra Leone, Kamerun and the Congo). PALPOPLEURA (Rambur, 1842). A genus of comparatively small to very small forms, conspicuous by coloured wings, short depressed abdomen and the curious sinuate course of the costal vein in its ante-nodal part.
