Show 1892.] COLEOPTERA FROM CENTRAL AFRICA. 91 Family CHRYSOMELID^E. (By C. J. Gahan, M.A.) MEGALOPODIN^E. 4. P(ECILOMORPHA MURRAYI, Baly. This species was founded upon specimens from Old Calabar. EUMOLPIN^E. 5. CORYNODES BONNYI, n. Sp. C. cyaneo simillimus, sed differt elytris crebre punctalis nitidis, et articulis antennarum quinque ultimis plus dilatatis. Long. 10| millim. Resembling very much in colour and general appearance C. cyaneus, Fabr. The last five joints of the antennae are strongly dilated, the seventh joint triangular, the eighth to eleventh subquadrate, transverse, the ninth and tenth each almost as broad as long. Pro-thorax shining, sparingly and not very distinctly punctured. Elytra rather dull, thickly punctured. Claws of tarsi cleft, with the inner division acute, shorter than the outer. The species may be distinguished from C. compressicornis (which it resembles in the punctuation of the elytra) by the greater dilatation of the apical joints of its antennae and by the sparser punctuation of its pronotum. 6. COLASPOSOMA ARUWIMIENSE, n. Sp. Cyaneum, nitidum; pedibus viridescentibus; prothorace quam latior vix duplo lonqiore, dense punctulato ; elytris crebre et sat punctatis, lateribus utrisque obtuse vel obsolete Long. 8-10 millim. Dark blue, with the legs metallic green; head, prothorax, and scutellum varying to metallic green. Head rather thickly and not very strongly punctured. Prothorax with its median length rather more than half the width measured across the base ; thickly and not strongly punctured above; lateral margins rather feebly convex. Scutellum sparsely punctured. Elytra very thickly and rather strongly punctured, with the punctures running together to form a feeble rugosity on the sides just below and behind the shoulders. Beginning a little behind the shoulder there is a single obtuse and slightly elevated costa, along the side of each elytron ; this costa is sometimes obsolete. The shoulders of the elytra are slightly prominent. The present species may perhaps be only a local variety of a species (C. fairmairei, Lefev.) occurring in Old Calabar. The latter has the prothorax much more distinctly punctured, the punctures being larger and less closely placed together. The colour is very variable-dark blue, metallic green, and bronze-purple. 7. COLASPOSOMA, Sp. A single specimen, differing from the preceding in its colour-a |
