Show 1890.] COLEOPTERA F R O M C E N T R A L AFRICA. 489 and offers similar colour-varieties to those described from the R. Quango by Quedenfeldt. It is distinguished from its allies inter alia by the usual green fasciae on the thorax and base of the elytra being reduced to distinct spots. None of the numerous examples collected by Mr. Bonny show a continuous basal fascia on the elytra. TRAGOCEPHALA NOBILIS, Fabr. One example of a variety in which the yellow basal fascia of the elytra is wanting. TRAGOCEPHALA ? Three examples of a species apparently new, but so discoloured that they cannot be profitably described. TRAGOCEPHALA OPULENTA, Harold, Col. Hefte, xvi. p. 228; Quedenfeldt, Berl. ent. Zeits. 1883, t. i. f. 5. This fine species has previously been recorded only from the Loango coast country. ALPHITOPOLA JANUS, n. sp. A. pallidae (Thorns.) quoad formant simillima (thorace latiore, transverso excepto) ; supra fulva immaculata, fronte, antennis, pedibus corporeque subtus nigris ; subtilissime griseo-pubescens. Long. 18 millim. 2 • Subcylindrical, slightly narrowed behind, clothed above with a reddish ochreous tomentum, the antennae, legs, and under surface being shining black, with an extremely fine and short grey pile. The forehead is also black, but this may be due to abrasion in the specimen ; the tawny pile of* the thorax clothes the flanks up to the anterior coxae, and the side pieces of the mesosternum are similarly but more thinly clothed. The thorax is short and broad, and its sides have a minute and acute tubercle, but the two strong basal furrows and flexuous subapical shallow sulcus are precisely as in A. pallida. The prosternum is narrow and simple between the coxae, and the mesosternum produced into a conical tubercle as in the typical species of the genus. The cicatrice of the scape is limited by a sharp, incomplete ridge. CHARIESTHES AROWIMIA, n. sp. C. bellae (Z)rtZm. = carissima, Westw.) similis et affinis ; differt pree-cipue signaturis elytrorum, viz. fascia rufa subbasali oblique suturam descendente et antice ramulos duos ad basin emittente fascia rufa postmediana cum maculis cluobus marginalibus con-juncta ibique guttam viriclem includente; area viridi apicali maculis nigris liberis tribus, denique margine laterali sat fusco, maculis nigris quatuor anterioribus conjuncto. Long. 10| millim. There is one (imperfect) example only of this pretty little species, which may be perhaps more correctly considered a local form of the |
