CeratorrMna ( Aphelorrhina) simillima^ Westvv. 
C. (Aphelorrhina) simillima, Westw. Arcan. Ent. i. p. 72, t. 19. f. 4, 
aud p. 181. 
£. Dark green as in C. guttata , spotted in the same way, 
but the spots are very small; it is of a narrower form, the 
clypeus is unarmed, the thorax is more narrowed in front, the 
sides not angular before the middle, the punctuation is 
stronger, the copper-colour is almost wanting, except traces 
at the sides and base of the thorax. From the male o'f 
G. Julia it differs in having the clypeus much longer and 
narrower, densely longitudinally strigose-punctate, whilst in 
C. Julia the fore part of the clypeus is rather sparingly and 
finely punctured, the anterior angles are not reflexed; the 
intermediate tibite are slightly curved at the base ; the pygi- 
dium is more densely transversely strigose ; posterior tibke 
with no external tooth.

Hab. Sierra Leone. Type in Brit. Mus. 
Ceratorrhina ( Aphelorrhina ) bella , n. sp. 
J . Coloration exactly as in C. guttata , but with the form 
of G. simillima , having the thorax regularly narrowed ante¬ 
riorly. From G. guttata it differs in the absence of the horns 
on the head, &c. From G. Julia it differs in colour and in 
the form of the thorax ; the intermediate tibise are somewhat 
curved at the base; the clypeus as in G. simillima. From C. 
simillima it differs in the presence of the copper-colour on the 
suture of the elytra, in having a distinct tooth on the outside 
of the posterior tibia3, and in having the white spots on the 
elytra larger. From all the foregoing it differs in having the 
third spot of the mesial line of spots on the same level with 
the first spot of the sutural line of spots, so that there are four 
spots in a straight line across the middle of the two elytra.

Hab. Mongo-ma-Lobah. 
G. simillima and G. bella differ from the other species in 
having the sternal process much narrower and more acuminate. 
CeratorrMna ( AphelorrMna ) tibialis , n. sp. 
J. Coloration of C. guttata , but rather paler, of a more 
elongate form, the thorax regularly narrowed in front (not 
angular at the sides) ; elytra much more narrowed towards 
the apex ; the spots are very much reduced, those near the 
suture being transverse, and the apical spots are wanting. 
The clypeus is simple, nearly as in G. simillima , but not
