ON THE CETONIID^ 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 Coryplie. 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 Hke manner, is often prominent and acute. The females have the anterior 

 tibiae externally tridentate, but the males have them without teeth. The maxillse are long, with 

 the terminal lobe also long and villose. The mentum is more or less emarginate ; and the groupe 

 is almost pecuhar to New Holland and the adjacent islands. The species called Schizorhina 

 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 car'mata of Donovan with the C. PMllipsii of Schreibers. Being 

 in 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 or of the islands adjacent to New Holland, has a narrow advanced mesosternum — 

 elytra 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 tibise 

 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 Dej can'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
