 !■.'. Mecaspis laetum. 



CnUii:hroiitii kuliiiii Hope, l.r. p. 368. no. 58 (1843) (Cape Palmas). 



Greenish blue, or blue ; antenna and legs black. No velvety pubescence on 

 pronutum and elytra. M. dives Pascoe, Tr. Ent. Sov. Lond. p. 405 (1888), from 

 Delagoa Bay, seems to be the same. 



Vi- Mecaspis atripenne. 



CaUirlinima atrijiciine Hope, Ix. no. 5'J (1843) (Sierra Leone). 



This is a well-known species, which cannot be confounded with any other 

 Mecaspis. 



14. Callichroma igneicoUe. 



Callkhroma igneiculle Hope, I.e. no. 60 (184.S) (Ashanti). 



Callichroma imiktior Jordan, Noi: Zool. i. p. 168. no. 86 (1894) (Gold Coast). 



My imitator is the same as igneicolle. There are in collections several 

 similar forms which have received names. They differ slightly from igneicolle, 

 especially in the plication of the pronotum. Their distinctness is doubtful. 



15. Oxyprosopus speciosus. 



Ceramb;/.c sjieciofus Dalman, in Sclwenh,, Stjn. lux. i. 3. App. p. 153. no. 210 (1817) (Sierra Leone). 

 Promeces carhonariiis Hope, I.e. no. 61 (1843) (Sierra Leone). 



Bluish black, legs yellowish tawny. The only (h£ypro.iopus of this colour 

 known to me. 



16. Euporus amabilis. 



Eiijjorus amabilis Hope, I.e. no. 62 (1843) (Cape Palmas). 



Anterior half of pronotum purplish blue like the occiput, without any punctures; 

 disc of the dilated central part of the prothorax densely punctured, the pnncturation 

 more dispersed on the sides. Shoulders smooth, glossy, but the area between 

 the shoulder and the scutellum as densely rugate as the rest of the elytrum. 



17. Euporus strangulatus. 



Euporus strangulaliis Serville, Ann. Sor. Ent. France, p. 21 (1834) (East Indies?). 

 Rhopalophora? respletideiis Newman, Enl. Maij. v. p. 496 (1838) (Fernando Po). 

 Euporus chrysocollis Hope, I.e. no. 63 (1843) (Fernando Po). 



The puncturatiou of the thorax is very coarse ; the anterior half of the 

 pronotnm is not (juite smooth, there being .some large punctures in the depression ; 

 the punctures on the disc of the wider part of the prothorax are centrally less 

 numerous than at each side of the middle line, the: smooth area penetrates mesially 

 into the patch of punctures. There occurs a similar species in the same districts 

 which has a broader jirothorax, with the centre of the wider portion very densely 

 punctured. 



18. Sternotomis principalis. 



Lamia principiili s Dalman, in Sc/ionnli., Si/ii. Ins. i. 3. App. p. 162. no. 223 (1817) (Sierra Leone). 

 Stemodonia paliui Hope, I.e. no. 04 (1843) (Sierra Leone). 



In this form the sjwts in the posterior iuilf of the elytra are green. We have 

 several specimens from Sierra Leone. The individuals from Angola have all the
