CETONIIDiE OF AFRICA.

the apical (mesosternal) portion, small, and not wider than the 
extremity of the metasternal portion. 
Nearly every species in the group thug naturally associated is dis¬ 
tinguished by splendid green or golden colours. This is, in fact, the 
case with all those which are natives of the tropics ; but I have re¬ 
ceived, within the few last days, two species from Mr. Melly from 
a more southern latitude, both of which exhibit white velvet-like 
patches, and one of them is entirely destitute of metallic tints. 
In the ColeopterisCs Manual of Mr. Hope (vol. i, p. 119) a genus 
was proposed under the name of Dicronorhina, comprising Cetonia 
micans, Daphnis and Grallii, characterised by the internally spinose 
fore tibiae of the males. As however several species are now known, 
(D. Nireus, Burkei, 4-maculata and guttata) the males of which 
possess unarmed fore tibiae, I have considered it as likely to lead to 
less confusion by uniting them under a different generic name. 
The group now proposed, comprises Mr. MacLeay’s sub-sections 
3, 4, and 5 of the section 6 Goliathi Smithii,’ and his 4tli sub¬ 
section of Coryphe Naricise, with several other species which must 
have been formed into other sub-sections according to his arrange¬ 
ment. 
By Dr. Burmeister they are formed into the genus Dicronor- 
rhina, and portion of Coelorrliina, which are, as it appears to me, 
unnaturally placed in different sections of his family Goliathidse. 
They may be formed into several sections as follows :— 
A. Tibi® antic® intus denticulate?. 
a. Clypeus g in cornu obtriangulare porrectus . . (1. Dicronorhina, Hope.) 
b. ,, „ furcatum porrectus . . . (2. Eudicella , White). 
B. Tibi® anticse intus hand dentat®. 
a. Clypeus $ in cornu obtriangulare medium porrectus. 
a. Corpus baud metallicum, tarsi antici $ apice peni- 
cillato ..... ... (3. Cheirolasia , Westw.). 
j8. Corpus metallicum tarsi antici baud penicillati. 
* Caput $ cornu postico armatum clypeus 
<j> baud recte truncatus .... (4. Taurhina , Burm.). 
* * Caput baud cornu postico armatum ; 
clypeus $ recte truncatus . . . . (5.^ Ccelorrhina, Burm.). 
b. Clypeus in cornua duo lateralia porrectus . . (6. Stephanorrhina, Burm.). 
Section 1.— DICRONORHINA, Hope . 
The first of these sections, which has for its type the typical 
species of Mr. Hope’s genus Dicronorhina (a name altered by 
Dr. Burmeister to Dicranorrhina), namely the Cetonia micans of 
Drury, is further characterised by having the inner lobe of the 
maxillae in both sexes destitute of a tooth, which is found, at least
