macular, the spot on the fifth interstice of both fascia? being much 

 shorter than the others ; on the hinder fascia the spot on the sixth 

 interstice is extended forward and that on the seventh prolonged 

 behind. 



Teffltjs jamesoni, n. sp. 



T. raffraj'i {Chaud.) affinis, seel divert, inter alia, corpore toto 

 f/lahro. Nifjer, thorace sat angusto he.vagono, sujjra grosse 

 conjluenter et suhrugose puiictato, lateribus postice leviter sinuatis, 

 angulis p)OSticis obtusis ; elytris graciUter ovatis, utnnque acute 

 sexcostatis, costis prope apicem 2—6 et 3-5 conjunctis, inter- 

 stitiis multo grossius quam in cceteris speciehus transverso- 

 foveolatis et granulis medianis inter se valde distantihus. Subtus 

 Icevissimiis; tibice anticce extiis recta ; antennce sicut in T. violaceo 

 graciles ; frons inter oculos et in svJcis longitudinalibus rugoso-

 Long. 35 millim. 



This species belongs to the group defined by Kolbe as having 

 (besides the raised suture) only six carinse on each eljtron, and 

 difi'ers 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 there- 

 fore obtuse as in T. raffrayi, and not rectangular as in T. juvenilis, 

 from which also the species difi'ers 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. Eonny also met with it. 



Ckaspedophoeus erichsonii, Hope. 



Ceaspedophoeus oxygonus, Chaudoir. 



The two preceding species are widely distributed on the West 

 Coast, C. oxggonus extending as far as Sierra Leone. 



Chljenius artjwtmitjs, n. sp. 



C. lucidieolli (Laferte) similis et affinis, sed valde differt elytris pro- 

 fande striatis, striis puheseentibus latenbus pjunctulatis. Cajjut 

 et thorax splendide cupreo-cenea, hoc sparse punctata illo piostice 

 punctulato ; partibus oris, antennis pedibusque rufis ; elytris 

 nigris. 

 Long. 17 millim. S . 



The abdomen and presternum, 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 strife the species resembles 

 the C. lissoderns (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
