TAXONOMICAL PART Ortholema mandarensis (JACOBY, 1897) comb. n. (Criocerinae) Material - Laos, Vientiane, 200 m, 9-10 April 1998, at light, 1 specimen. Remarks - Lema mandarensis JACOBY, 1897 is herewith transferred to the genus Ortholema HEINZE. Lema funerea JACOBY, 1908, syn. n., Ortholema elongatior PlC, 1926, syn. n., O. punctaticeps PlC, 1929, syn. n. are new synonyms of this species. Prothorax of this species is dark blue, mostly more or less red at base, rarely entirely red. This species is widely distributed in southern and eastern India, Assam, Thailand, Cambodia, Laos, Vietnam, South China and Sumatra. From Sumatra I have seen a specimen with HEINZE' s label li Incisolema advena n. sp." (manuscript name). Coenobius ruficollis, sp. n. (Cryptocephalinae) Description - Black; head, 6 basal segments of antennae, prothorax and legs fulvous. Body robust, ovate. Head shining, with deep sparse punctures. Antennae with segments 6-11 thickened, segments 7-10 as long as wide. Prothorax short, 1.9 times as wide as long, strongly narrowed anteriorly, side margins feebly rounded, hind margin with median lobe rounded. Surface with a row of punctures along basal margin and transverse grooves on each side interrupted in middle; rest of surface impunctate or with a few punctures near hind angles. Scutellum lanceolate. Elytra 1.1 times as long as wide, punctures in rows not deep, interspaces broad and flat, except two outermost. Pygidium densely punctate. Pygidium finely and densely punctate with microsculptured surface. Prosternum quadrangular, twice as wide as long, ridged on sides. Segment 1 of anterior tarsus of male slightly thickened. Length 1.85-2.5 mm. Type material - Holotype (LM): Vietnam, Shapa, 1500 m, April 1975, L. MEDVEDEV leg. Paratypes: same locality, 1 female (LM); - Vietnam, prov.Vinh-Phu, Tarn Dao, 900 m, 12-22.IV. 1986, leg. L. MEDVEDEV, 2 females (LM); - Laos, Champassak Prov., Dong Hua Xao NBCA, 2 km S of Nong Luang village, the bank of Touay-Guai stream, 15°4'N, 106°13'E, 800 m, 1-5 April 1998, 1 male, 1 female (HNHM). Remarks - This species might be compared in the Indochinese fauna only with C. subsemicinctus PTC, 1943, which however has bicolorous elytra. Similarly colored are C. baronii LOPATIN, 1979 from Himalaya, which is smaller (1.5-1.7 mm) and with differently sculptured prothorax and C. sulcicollis BALY, 1873 from Japan and possibly South China, which is larger, with strongly punctured basal part of prothorax.
