We have a female from Benitci, Portuguese Cameroous, which agrees with 

 the nymotype of africanus, but the apical area of the elytra is twice the size 

 (about 4i mm.) and the lobes of the aiitenual segments are narrower. I name 

 this form 



P. africanus bfuitrnsi^ sub.sj). nov. 

 ft. Phyllarthrius unicolor. 



PhyUaHhritis unicolor Hope, l.r. p. 3fi7. no. 51 (1843) (Ashanti). 

 1 have not seen a second specimen of this species. 



fi. Phycholaemus signaticollis. 



ffamalicherus signatirotlis Hope. I.e. no. 52 (1843) (Cape Palmas). 



Phi/cltiilaemu.^ troberti Chevrolat, Ann. Sac. Ent. Fraru:e p. 324. no. 5 (1858) (Guinea). 



This Species is the same as trobt'iii ('hevr. 



T. Plocederus viridipennis. 



HamaticTieiiis virklipennh Hope, I.e. no. 53 (184:-)) (Sierra Leone). 



Antenna and legs yellowish tawny. Prothorax as in P. cldoropfenis, the 

 transverse folds not quite so regalar, the si)ine pointed. Elytra tawny, but 

 this colour almost entirely suppressed by a blue-green gloss ; puncturation more 

 minute than in chloropterm \ sutural angle with a short tooth, outer angle with 

 a longer one. Abdomen tawny ochraceous. 



8. Domitia pilosicollis. 



Uamaticherm jMosicollis Hope, l.r. no. 54 (1843) (Cape Palmas). 



This is not a Cerambycid, but a Lamiid. It belongs to Domitia, which is 

 nearly allied to Monochamiis, and is very near to J), aenea Parry (1849), the type 

 of which I have not comjjared. D. aenea stands under Sternotomis in the Munich 

 Catalogue. 



i>. Plocederus glabricoUis. 



Hamalirheriis glulrholUs Hope, I.e. no. 65 (1843) (C'ape Palmas). 



Legs and the first segment of the antenna tawny red, rest of antenna blackish 

 tawny; knees black. Thora.x smooth on disc, with some minute punctures and 

 posteriorly two callosities ; no sjiine on the side, but three callosities. Elytra 

 green ; puncturation minute and sparse ; sutural angle with acute spine, outer 

 angle pointed, but very little produced. 



10. lonthodes amabilis. 



Iimthoiles amabilis Hope, I.e. no. 51! (1843) (.Sierra Leone). 



The type-specimen seems to be somewhat discoloured. The elytra are 

 blue with a velvety streak along the centre of each. The spots of the prothora.x 

 are white, while they are yellowish in our specimens from Sierra Leone.

Callichrnma as-siiuilf Hope, I.e. no. 57 (1843) (Sierra Leone). 



1 consider this to be the same as <'. nfriim L. (1771).
