Oulema depressa sp.n. Head and prothorax yellowish red, underside otherwise black; antennae yellowish red at base, apical half of 4th and 5th and entire 6th-llth segments brown, legs yellowish red with outer half of tarsi dark brown; scutellum brownish, elytra metallic black with bluish sheen. Frons not elevated, in hind part with a small pit. Eyes very slightly incised, behind the eyes an uncommonly sharp furrow (fig. 2). Antennae moderately slender, 5th segment slightly more than twice as long as broad, the following ones about 1.5 times as long as broad. Pronotum slightly longer than broad, flattened, sides weakly rounded, fore corners with weak, indistinct tubercle. Disc punctated on sides, along mid line only in anterior half. Constriction comparatively shallow, basal furrow weak and shallow, weakly punctated, in the middle with a distinct, sharp depression that reaches foreward. Elytra flattened, parallel-sided, about 1.8 times as long as together broad, striae strong with large punctures, intervals unpunctated, very little elevated. Length: 3.5 mm, breadth: 1.4 mm. Holotype: Tanzania, Morogoro, light trap, 11.1970, T. PÓCS. Fig. 1. Aedeagus of Oulema vittigera sp.n. - Fig. 2. Head and pronotum of Oulema depressa sp.n. O. depressa is only known from the holotype. It is comparatively isolated within Oulema

, and easily recognizable by the shape of the head and the pronotum (fig. 2). In these characters it approaches the genus Incisolema

, which in fact is considered by some authors (e.g. MONROS 1960) to be a subgenus of Oulema

. In coloration O. depressa resembles O. pembanensis

, which has a much more convex pronotum. REFERENCES GRESSITT, J.L. & KIMOTO, S. (1961): The Chrysomelidae (Coleopt.) of China and Korea. Part 1. - Pacif. Insects, 1: 1-299. LATREILLE, P.
