ON THE CETONIID^ OF SOUTH AFRICA. 



we see that in the male these angles of the clypeus project into horns on each side of 

 the large central horn. In the present section, Inca, but still more in the next section, 

 which Mr. Hope has marked out under the name of Dicronocephalus, the male has no horn 

 proceeding from the middle of the margin of the clypeus, but only those horns which arise 

 from the angles of the clypeus. Inca is a section entirely confined to South America. I 

 shall now content myself with the enumeration of the species described by authors, and 

 merely observe that my collection is in want of specimens of G. hifrons, rufipennis, and the 

 male of Goliathus Ynca, Fab.

 Note. This species possesses the thorax marked in that very peculiar way which so singularly charac • 

 terizes the Gigantic section.

 Note. The Goliathus inscriptus of Kirby appears to be only a variety of this species. 



Sp. (Cetoninus) Goliathus rufipennis, G. P. 



Inca rufipennis, G. P. p. 109. tab. 14. fig. 4. 

 Note. I am aware that MM. Gory and Percheron assign some of the above names to certain of their 

 private friends. But I find it convenient for quotation to consider the true namer of an insect to be that 

 person in whose work I find it for the first time described. 



Section 5. Dicronocephali, Hope. 

 73. This section is Asiatic, and has the sides of the elytra nearly parallel. It agrees with 

 the last in having the anterior tibiae furnished externally with teeth in both sexes, but it differs 

 in having the epimeron more or less prominent between the angles of the thorax and elytra. It 

 agrees with the section of SmitUi in its body being depressed, but then the male has never 

 the anterior tibiae internally multidentate. Between the anterior ungues there is a plantula in 

 form of spine, which is armed at the apex with diverging pseudonychia. The mesosternum is 

 not much produced between the legs, and sometimes is barely visible. The horns of the 

 head seem, as I have said before, to be productions of the lateral teeth of the clypeus in the 

 Gigantic section, that is, of the angles of the female clypeus, and the bifurcated horn of the 

 middle of their clypeus is wanting. The section admits of the following sub-sections :—
