ON THE CETONIIDiE OF SOUTH AFRICA. 
of Goliathus, which I shall call Smithii, after my friend Dr. Smith. There is another species 
mentioned by M. Schdnnherr, and described in his appendix under the name of Cetonia geotru- 
pina, which I am clearly of opinion belongs to the sub-genus Ischnostoma, and to the section 
of it called by me Ccelocephalce.

68. This section inhabits intratropical Africa. It may be easily known by having the elytra 
wider at the base, by having the body very depressed, by the thorax being nearly truncated 
behind, or, at least, being only slightly emarginate, to receive the scutellum. In short, this 
groupe comes very close to the general form and colouring of the sub-genus Coryplie, and 
the female indeed, not having a horned clypeus, can with difficulty be distinguished from it. 
The males have almost always the anterior tibise denticulated on the inside. The Goliathi 
Smithii have a quadrate head, and admit of the following sub-sections, which I shall not name, 
as my object is merely to shew their structure and affinities : —
