9 mill. — Oblong. iEneous below; above metallic green; head wllh 

 two, thorax and elytra willi four longitudinal dark purplish bands. — 

 Var. : Entirely greonisli or brownish aeneous. — Head deeply and closely 

 punctured, dark purplish, a central longitudinal short band and the 

 clypeous metallic green. Autennse black. Thorax narrowly Iransverse, 

 sides uearly straight at the base, then to the apex slightly rounded ; 

 surface very clusely punclate near the sides, more remotely at the disk, 

 metallic green, this coiour dividod by four longitudinal bands, oî which 

 the 2 middle ones are the broadest, but do not quite touch the apex, 

 the bands placed at nearly equal distance froni each other, another 

 shorter purplish spot is placed on each side at the extrême latéral mar- 

 gin. Sculellum depressed at its hase, deeply i)uuclured. Elytra of exactly 

 the sanie shape and sculpture as in C. gibbkollc, metallic green, each 

 elytron with a subsutural hroad dark purplish band, and another latéral 

 one, both uniting at their apex. Underside and legs œneous, flnely pu- 

 bescent, anterior femora with a very short tooth. — Zanzibar. 



A variety does not dilTer except in its uniform coiour of green or 

 brownish œneous, but in certain lights traces of the darker bands are 

 also hère visible. 



Je rapporte à cette description un individu venant de Tabora et qui 

 présente quelques légères différences. La coloration est bien d'un vert 

 métallique, mais les bandes sont d'un brun rouge cuivreux un peu 

 moins brillanl que le fond, et le corselet présente une petite bande mar- 

 ginale très courte ; en outre, l'écusson est plus fiiiemenl ponctué. Les 

 fémurs anlei'ieurs ont également une très petite dent en dessous.
