ON THE CETONIIDiE OF SOUTH AFRICA. 
Anoplocheilus tomentosus is sub-emarginate, the species appears to belong to a different section of the sub- 
genus when compared with Anoplocheilus spinitarsis. If on dissection of the mouth they should agree 
with the genus Cetonia , these two species A. setosus and A. tomentosus will evidently enter into the 
last Trichoid section of the sub-genus Cetonia. 
Sub-genus 3. Diplognatha, G. P. 
40. This sub-genus of M. Gory agrees with Anoplocheilus in having the end of the maxilla 
armed with sharp teeth. Indeed this is the character of the whole genus Macrominus ; but 
the terminal process is in Diplognatha distinct from the base of the maxilla, and is furnished 
on the outside with a brush, as in the genera Trichinus, Cetoninns, and Gymnetinus. The 
mentum also is broad, truncated, scarcely emarginate iu front, and having the corners rounded 
off. But for the rest I refer to MM. Goiy and Percheron’s description of this groupe, which 
appears to admit of the following sections. As all the sections, however, are not yet known, 
it is difficult to place them accurately ; and I give the following arrangement only provi- 
sionally : —

41, The first of these sections is numerous in species. The type of it may be considered to 
be Cetonia crucigera of Olivier. Cremastocheilus maculatus of Gory appears to form another 
section. The general colour of the first section is black, often variegated with white spots. 
42. To the second of these sections appears to belong the common Cape insect, Scarabeeus 
carnifex of Linnsous.

Note. MM. Gory and Percheron seem to have confounded this last species with the true Cetonia 
Gagates of Olivier, which is a Senegal insect, and smaller, having the labial palpi stretching beyond the 
mentum, the sides of the elytra parallel, the anterior tibise tridentate, and the mesosternum rather obtuse. 
I have found Diplognatha Gagates common at Porto Praya in the Cape de Verds ; but I cannot say that it 
is a flower-frequenting insect, as I never met with it except in the Cocoa-nut groves below the town, and
