Oulema vittigera sp.n. Head and pronotum piceous, frons with indistinct reddish markings along furrow, pronotum with brownish yellow base; antennae brownish yellow at base, from 5th segment on darker brown, legs brownish yellow with outer half of tarsi darker, underside yellowish brown; scutellum piceous, elytra brownish yellow with piceous border along side and hind margins and suture. Frons somewhat elevated, in hind part with a small pit. Eyes with very slight incision. Antennae comparatively slender, 5th segment about 2.75 times, the next ones about twice as long as broad. Pronotum strongly convex, slightly longer than broad, sides almost straight until the constriction, fore corners with distinct but short tubercle. Disc punctated on sides and along mid line, inbetween unpunctated. Constriction sharp, basal furrow densely punctated. Elytra parallelsided, about 1.75 times as long as together broad, striae with strong punctures but not otherwise impressed, intervals unpunctated, not elevated. Male genitalia: Aedeagus comparatively broad, strongly bent (fig. 1). Length: 3.4 mm, breadth: 1.4 mm. Holotype: Guinea, Kalledu, V.-VI.

1970, leg. K. FERENCZ. O. vittigera is only known from the holotype. It resembles O. raff ray i (Chap.), but differs in the coloration of the pronotum, by smaller size, by somewhat more slender antennae and by the strongly bent aedeagus. From O. alterna Silfv. it differs by smaller size, by pale legs, by pronotal coloration and by the strongly bent aedeagus (in O. raffrayi and O. alterna the aedeagus is comparatively straight, see SILFVERBERG 1979). Oulema infima (Lacordaire, 1845). - Ghana, Northern region, Tamale, 184 m, N 8°25' -W 0°53', Dr. S. ENDRŐDY-YOUNGA, Nr. 418, light trap, 11.IH.

1970, 21 ex.; ibid. Nr. 419, 2 ex.; ibid. Nr. 420, 1 ex. - Previously recorded from Senegal and from Niger eastwards to Ethiopia. Oulema leleupi (Bryant, 1960). - Tanzania, 1.5 miles to Lake Sereri, E shore, 3150 feet, coll. Dr. J. SZUNYOGHY, singled material, 11.-27.VIII. 1965, 1 ex. - Recorded from Kenya and Tanzania. Oulema subfusca sp.n. Head and prothorax reddish yellow, underside otherwise black; antennae reddish yellow, from 6th segment on brownish, legs yellow with last tarsal segments brownish; elytra and scutellum dark metallic blue. Frons not elevated, in hind part with a small pit. Eyes with a very shallow incision. Antennae comparatively slender, 5th segment almost 2.5 times, the next ones 1.5-1.75 times as long as broad. Pronotum about as long as broad, sides rounded, fore corners with distinct but short tubercle. Disc convex, punctated on sides and along mid line, inbetween unpunctated. Constriction moderately deep. Basal furrow sharp, densely punctated. Elytra parallel-sided, about 1 2/3 times as long as together broad, striae strong, with large punctures, intervals unpunctated, distinctly elevated in apical half, especially the outer ones. Length: 3.5 mm, breadth: 1.7 mm. Holotype: W.Africa, Guinea, Coyah, 24.X.

1967, leg. K. FERENCZ. O. subfusca is only known from the holotype. It resembles O. methneri (Hze.), but can be distinguished by the black underside. Also the antennae are somewhat more slender, the tubercles at the pronotal fore corners are shorter, and the elytral intervals are more convex. Oulema punctatissima (Heinze, 1931). - Liberia, Monrovia, 11.IV. 1965, netting, Dr. S. ENDRODY-YOUNGA, 1 ex. Ghana, Northern region, Tamale, 184 m, N 8°25'-W 0°53'
