130 ON THE GOLIATHIDEOUS CETONIIDA 
and ©. africana under a new genus Chlorocala, without any 
description. Messrs. Gory and Perchéron, however, injudiciously 
adopting a principle far too general, and which has led to almost 
irremediable confusion in entomological nomenclature—(namely, 
that they were at liberty to select any given species as the one to 
which the old generic name might be attached when the genus 
became dismembered), retained the C. africana as the type of 
Gnathocera, and gave the insects which are the true types of 
Gnathocera under a new generic name, Amphistoros. 
Mr. MacLeay, in the Illustrations of the Zoology of South Africa, 
restored the name of Gnathocera to the latter of these two groups, 
whilst for the former he took up the name Coruphes, originally 
proposed for it by Gory and Perchéron, but which he has altered 
to Coryphe. Under this name it constitutes Mr. MacLeay’s second 
subgenus of Cetoninus, intervening between the two other sub- 
genera, Schizorhina and Goliathus. Of Schizorhina I have not 
hitherto treated, except by giving Mr. MacLeay’s divisions of it, 
and describing some new species (ante, p. 103), but his divisions 
of Goliathus will be found ante, p. 6. Mr. MacLeay observes 
upon Coryphe, that it is extremely close to Goliathus, from which 
it may be known “by the maxille having the terminal process 
shorter, and in a line with the base, and by the mentum being more 
truncated; but, above all, by the horny part of their mandibles being 
much longer than the square membranous part. The males scarcely 
ever have any teeth on the external side of the anterior tibize, and 
when they possess such teeth, it is merely because they belong to 
aberrant species.” —Illustr. Cet. So. Afr. p. 29. 
The following are Mr. MacLeay’s Sections of Coryphe :—
