Show 1890.] COLEOPTERA F R O M CENTRAL AFRICA. 483 ARCHON CENTAURUS, Fabr. A well-known African Dynastid, found commonly in the coast-regions of Guinea. Family CETONIID__E. CERATORHINA SAVAGEI, Harris. Several examples, differing in nothing, except the rather broader fulvous stripes and spots, from the species as found on Mt. Cameroons. ECCOPTOCNEMIS LATIPES, n. sp. E. thoreyi simillima, sed differt tf tibiis posticis brevibus intus ante medium dente magno triangidari instructis, coxisque posticis o* 2 extus fulvis vel sanguineis. Long. 29-33 millim. d 2 • Differs from examples of E. thoreyi (Schaum) from the Guinea coast in the silky-golden reflections of its green surface and the stronger sculpture, minutely rugulose-punctate with scattered larger punctures, and the reddish outer-lateral part of the posterior coxae. The apices of the elytra are more strongly sinuated and the sutural tooth longer. In the male the hind tibiae are conspicuously shorter and broader, and the tooth at the commencement of the deep emar-gination at the base is very large. The glabrous inner margin of the same tibia? and the short, scarcely perceptible pubescence of the intermediate tibiae distinguish it, beside colour, from E. barthi (Harold). SMARAGDESTHES MUTICA, Harold. Described originally from examples taken by Pogge in the interior. A species or local form, very closely allied and agreeing in the slight elevation of the anterior margin of the clypeus, but differing in the more elongate form of body, is common on Mt. Cameroons. PL_ESIORHINA RECURVA, Fabr. A single example of a variety in which the elytra are testaceous yellow, except a broad border at the shoulders and another at the apex, which remain of the general brassy-green colour. The underside of the body, legs, lateral margins of the thorax, and mesosternal epimera are reddish. Similar varieties are found on Mt. Cameroons. PL-ESIORHINA CINCTA, Voet. PACHNODA MARGINELLA, Fabr. Similar to Cameroons examples. PACHNODA INSCRIPTA, Gory & Perch. One example, differing from Gory and Percheron's figure and description in the upper surface being testaceous-yellow like P. picturata (Bohem.), and the abdomen being free from white spots. |
