OF AFRICA. 179 
basal segments. The smaller specimen sent me by Mr. Melly had the horns of the head 
vather shorter, the spots of the elytra more confluent, the four hind legs entirely fulvous, the 
anterior tibie with the sinuations more distinctly marked so as to give them more the 
appearance of being tridentate (fig. 1g), and the four hind tibie more serrated (fig. LA, 1%). 
The maxille in this specimen were of a similar form to those of the larger specimen figured in 
the plate. 
Section 4.—TAURHINA, Burmeister. 
This section is distinguished from the last by its splendid metallic 
colour and by its fore tarsi being destitute of an apical brush, and 
from the following by, having the hind part of the head, in the 
males, produced into a broad curved horn (pl. 45, fig. 2a), whilst 
the centre of the front margin of the clypeus is porrected in the 
shape of a thick obtriangular horn; the front of the clypeus of 
the female (pl. 45, fig. 2d, from Schaum) is not straight. The 
inner lobe of the maxillze is simple in the males: (I have not seen a 
female in nature). The anterior femora and tibie, in the males, 
are singularly constructed, evincing an approximation to the 
internally serrated tibiee of some of the preceding species. The 
sternal process is broad and somewhat triangular at the tip, which 
is more porrected than in the last group (fig. 26, 2c). The 
abdomen is channelled beneath, and the pseudonychiz are distinct 
but very minute, the unguicule being scarcely visible. 
Species I, (XII.)—Ceratorhina (T.) Nireus (Plate 45, fig. 2.) 
Syx.—Dicranorhina Nireus, Schaum. Anal. Ent., p. 40, tab. annex. ¢ 9. Bur- 
meister, Handb. d. Ent., Vol. 3, p. 190. 
This beautiful species inhabits Guinea. The only specimen I 
have yet seen is in the collection of Captain Parry of Cheltenham, 
who has kindly permitted me to illustrate it in this work. 
« Section 5.—CCiLORRHINA, Burmeister. 
The type of this section exhibits equally splendid colours with 
Taurhina, from which it differs in the armature of the head of the 
male, which is thus described by Mr. MacLeay, who, I believe, 
alone possesses this sex :—‘‘ Clypeo antice concayo, cornu medio 
brevi recurvo, apice dentato, triangulum obversum simulante.” He 
also describes the anterior tibize as having no teeth externally or 
internally. The female has the head unarmed, with the front 
margin of the clypeus slightly emarginated ; the inner lobe of the 
maxille is strongly toothed; the front margin of the mentum is 
deeply incised; the anterior tibize are tridentate, and the four 
posterior ones have a tooth on the outside, beyond the middle. 
The sternal process is of the same form as represented in pl. 45, 
fig. 8a, 3b.
