macular, the spot on the fifth interstice of both fasciae 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. 



Tefflfs jamesoni, n. sp. 



T. raffrayi (Chaud.) affinis, sed difert, inter alia, corpore toto 

 f/lahro. Niger, thorace sat amjusto hexagono, supra grosse 

 conjluenter et subrugose punctato, lateribus postice leviter sinuatis, 

 angulis posticis obtusis ; elytris graciUter ovatis, titrinque acute 

 sexcostatis, costis prope apieem 2-6 et 3-5 coiijunctis, inter- 

 stitiis multo grossius quam in cceteris speciebus transverso- 

 foveolatis et granulis medianis inter se valde disfantibus. Subtus 

 Icevissimus; tibice anticce extus recta; antennce sicut in T. violaceo 

 graciles ; from inter oculos et in sulcis longitudinalibus riigoso- 

 punctaia, medio et antice Icevi, sutiira epistomali distincta. 

 Long. 35 millim. 



This species belongs to the group defined by Kolbe as having 

 (besides the raised suture) only six carinse on each elytron, 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. raffragi, 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. 



Ckaspedophoeus eeichsonii, Hope. 



Ceaspedophorus oxtgonus, Chaudoir. 



The two preceding species are widely distributed on the West 

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



ChL^NIUS AJlTrWTMIUS, n. sp. 



C. lucidicolli {Laferte) similis et affinis, sed valde differt elytris pro- 

 funde striatis, striis pidmcentibus lateribus pmnctulatis. Caput 

 et thorax splendide cupreo-cenea, hoc sparse punctato illo jjostice 

 punctulaio ; partibus oris, antennis pedibusque rufis ; elytris 

 niijris. 

 Long. 17 millim. c? • 



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 stria? the species resembles 

 the C. hssoderus (Chaud.), from Cameroons and Gaboon, belon^^ino' 

 to the same group ; but the double line of piliferous punctured oi" 

 the sides of the striae is peculiar to C. arutvimius, and the thorax in
