A distinct species. From C. transversicolle Chaud., and C. 

 hrevicolle SI., it is readily distinguished by the shape of tlie pro- 

 thorax, which is less subquadrate and transverse, and has the 

 posterior angles rounded ofi', not widely margined and prominent. 

 From C. leai SI., it is separated by size larger; form less convex; 

 prothorax more rounded on sides, more widely margined; elytra 

 far less convex, wider across base, lateral border much wider. 

 From C. madeayi Blkb., it difi'ers by head with preocular pro- 

 cesses (anterior anglesj not prominent; protliorax less convex, 

 margins wider; elytra with lateral channel wider. 



Cakenum leai, n.sp. 



lilliptical-oval, very convex. Head with frontal sulci short, 

 one supraorbital puncture on each side; prothorax transverse, 

 loliate, anterior angles prominent, posterior angles rounded; 

 elytra very convex, Wvigate, impunctate; anterior tibiae 3-dentate. 

 Head and undersurface black ; prothorax black, with wide 

 bluish-green margins; elytra nitid, rich purple on disc, chaly- 

 beous towards sides. 



Head transverse (5'2 mm. across eyes); front subdepressed; 

 preocular process small, rounded, not prominent; frontal sulci 

 short, deep, hardly divergent backwaids; eyes convex, not very 

 prominent. Prothorax transverse (4-5 x 66 mm.), convex, 

 strongly declivous to base; a light impression on each side of 

 base; sides subparallel; anterior angles narrow, prominent; basal 

 angles I'ounded; basal curve short, sinuate on each side of base; 

 basal lobe distinct, narrowly margined; border narrow, hardly 

 more prominent at posterior angles; marginal channel narrow, 

 slightly wider at posterior angles; median line lightly impressed. 

 Elytra oval(10 x 68 mm.), evenly rounded on sides; suture deep: 

 base not wide, very strongl}' declivous to peduncle; border on
