TEFFLT/S JAMESONI, n. sp. T. raffrayi (Chaud.) affinis, sed difert, inter alia, corpore toto glabro. Niger, thorace sat angusto hexagono, supra grosse confluenter et subrugose punctato, lateribuspostice leviter sinuatis, angulis posticis obtusis ; elytris graciliter ovatis, utrinque sexcostatis, costis prope apicem 2-6 et 3-5 conjunctis, interstitiis multo grossius quam in cceteris speciebus transverso-foveolatis et granulis medianis inter se valde distantibus. Subtus Icevissimus; tibice anticce extus rectce ; antennce sicut in T. graciles ; frons inter oculos et in sulcis longitudinalibus rugoso-punctata, medio et antice Icevi, sutura epistomali distincta. Long. 35 millim. This species belongs to the group defined by Kolbe as having (besides the raised suture) only six carina., on each elytron, and differs from the other species of the group in the absence of pilosity and the very coarse sculpture and widely-spaced line of granules in the interstices. The thorax is nearly as long as it is broad, the median dilatation is strongly angular, and the sides behind the angle oblique (very slightly sinuated) to the hind angles, which are therefore obtuse as in T. raffiragi, and not rectangular as in T. juvenilis, from which also the species differs in the perfectly smooth episterna. The specimen was contained in a small box of beetles, all that have been received in England of the Coleoptera collected by the late Mr. Jameson. Mr. Bonny also met with it. CRASPEDOPHORUS ERICHSONII, Hope. CRASPEDOPHORUS OXYGONTTS, Chaudoir. The two preceding species are widely distributed on the West Coast, C. oxygonus extending as far as Sierra Leone. CHL^NITJS ARDWTHIUS, n. sp. C. lucidicolli (Laferte) similis et affinis, sed valde differt elytris striatis, striis pubescentibus lateribus pjunctulatis. et thorax splendide cupreo-cenea, hoc sparse punctato Mo postice punctulato ; partibus oris, antennis pedibusque rufis; elytris nigris. Long. 17 millim. $ . The abdomen and prosternum, as in C. lucidicollis and allies, are impunctate, but the sides of the metasternum are thickly punctured. The thorax is precisely of the same form, i. e., quadrate with gently rounded sides, obtuse hind angles, and deep elongate basal fovea. In the depth and sharpness of the elytral striae the species resembles the C. lissoderus (Chaud.), from Cameroons and Gaboon, belonging to the same group ; but the double line of piliferous punctures on the sides of the striae is peculiar to C. aruwimius, and the thorax in |
