ON THE CETONIIDiE OF SOUTH AFRICA. 
appear to be aberrant in the section, and to connect it with the following one called Diceros. 
The following species indeed may perhaps represent so many sub-sections : — 
{ 
1 Cetonia elegans, Fab. 
2 Cetonia MacLeaii, K. 
f 3 Cetonia pretiosa, Each. 
t i Cetonia guttata, Olio. 
5 Narycius olivaceus, Dup. 
Colour green. $ Clypeus with no horn. 
Colour green with black spots. Clypeus with a short vertical horn.

Colour green and red with white spots. $ Clypeus with two lateral horns. 
Colour green. $ Clypeus with two lateral boms. 
60. With respect to the section Diceros, it is true that MM. Gory and Percheron have made 
a genus of it ; but except a slight difference in the form of the thorax, and the colour, we find 
little to distinguish the groupe from the section Naricicc, which I have founded on the badly 
characterized groupe which has been called Narycius by Dupont. The organs of the mouth 
are the same in both. However, there are as yet only two species described of the section 
Diceros ; namely, the Cetonia bicornis of Latreille, a Timor insect, which is figured in the 
fourth volume of the first edition of Cuvier’s Regne Animal, and the Dicheros decorus of Gory, 
which is a Javanese insect. The Cetonia bicornis of Latreille is called “ bicornuta” by Gory, 
and, what is singular enough, is erroneously assigned by Mr. Kirby to his own genus Gnathocera. 
61. The type of the third section Rhomborhinb? is the Gnathocera Hardwickii of Gory, a 
Nepaul insect, which is horned, and comes very near to the Goliathus 4 -maculatus of Africa. 
The difference between them consists in both sexes of Coryphe Hardwickii having the clypeus 
alike, and in the female having the anterior tibiae externally bidentate. Although I am not 
acquainted with the insect, I suspect that the Goliathus opalinus of Gory, which Mr. Hope 
is said to have made the type of his groupe Trigonophora, will eventually be found to form 
a sub-section of Rhomborhina, where the female has a simple clypeus. And I have reason 
to suspect, moreover, that the insect called “ Jumnos Ruckeri" in Mr. Hope’s Coleopterist’s 
Manual, forms still another sub-section of the Rhomborhina , which comes yet nearer to the 
sub-genus Goliathus than either of the former sub-sections, and osculates with it. All the 
species of this section are Asiatic. 
62. The fourth section, Schuppelli.®, is African, and may be easily known by the sharp 
prominent sternum, and by the anterior tibiae of the males being without teeth, while those of 
the females have externally three. This groupe will admit of sub-sections, of which the 
following insects appear to be types. 
A. — Males without teeth on f 1 Cetonia flavomaculata, Fab. £ with clypeus homed. 
the outer side of an-<j 2 Cetonia taenia, P . R. £ with clypeus simple. Posterior tibiae without a tooth, 
terior tibiae. |^3 Cetonia umbonata, King. £ with clypeus simple. Posterior tibiae unidentate. 
B. — Males having the ante- f 4 Cetonia suturalis, Fab. 
rior tibiae somewhatJ 
bidentate. |_5 Cetonia * * * * 
63. Dr. Smith has brought home the type of the first of the foregoing sub-sections, viz. : — 
Sp. 1 7- (Cetoninus) Coryphe flavomaculata, Fab. 
Gnathocera jlavomaculata, G-. P. p. 139. tab. 21. fig. 5. 
Note. MM. Gory and Percheron have only described tlio female. The male has a short horn on the 
vertex, and the apex of its clypeus is recurved and emarginate. The male has also its anterior tibise 
without teeth. By the way, the trivial name of this common species ought to be “ bimaculata" for no 
less an entomologist than Degeer originally described and figured it under tbis name. If this change be 
adopted, the Cetonia bimacula, Wiedem., which if it be the same as the Gnathocera bimaculata of Gory, 
appears to belong to some sub-section of Diceros , may then be called Coryphe Wiedemanni.
