ON THE CETONIIDiE OF SOUTH AFRICA. 
sent it in the genus. In fact, no insects of this genus have such a peculiarly cetonine aspect, if I may use 
the expression, as the brilliant species of Coryphe. But I proceed to the discussion of the sub-genera. 
Sub-genus 1. Schizorhina, Kirby. 
57. This is remarkably like Lomaptera, for the clypeus in both sexes is more or less cleft. 
The mesosternum, in like manner, is often prominent and acute. The females have the anterior 
tibiae externally tridentate, but the males have them without teeth. The maxillae are long, with 
the terminal lobe also long and villose. The mentum is more or less emarginate ; and the groupe 
is almost peculiar to New Holland and the adjacent islands. The species called Scldzorhina 
Brownii by Kirby is evidently the nearest to Lomaptera, as it presents vestiges of the lobate 
thorax. There are five sections known, for which the following names may serve in want of 
better : —

Note. As none of the above sections occur in Africa, I shall say little of them, except that Gory 
erroneously confounds the Cetonia carinala of Donovan with the C. Phillipsii of Schreibers. Being 
m possession of the identical specimens described by the latter naturalist in the Linnean Transactions, I 
have the means of judging; but I must confess that the two species come very near to each other. 
The last section, which I have called Insulares because they are in general natives of Mada- 
gascar oi of the islands adjacent to New Holland, has a narrow advanced mesosternum — 
elytia with parallel sides, and which are spinose at apex. The inner process of the maxilla 
in these insects has no tooth, and their mentum is deeply emarginate. All these circum- 
stances, and others, such as their peculiar colours, and the females having the anterior tibiae 
externally tridentate, show us how we may pass to the next sub-genus, which however will be 
found to have the clypeus never cloven. 
Sub-genus 2. Coryphe, G. P. 
58. This, as I have already stated, is called the genus Gnathocera of Kirby, in the monograph 
of Gory and Percheron. Now, as I have shown this to be an error borrowed from Dejean’s 
Catalogue, and as the present groupe is an excellent one, which had previously been named 
“ Coruphes” by M. Gory, on account, as he says, of its carinated vertex, I think no one will 
object to his first nomenclature, unless perhaps they may think it necessary to correct his
