ON THE CETONIID^ OF SOUTH AFRICA.

tropical regions of that vast continent. As to the section which I have named Myodermi, and which 

 corresponds with the genus Myoderma of Dejean's Catalogue, I only know it by M. Gory's bad figure 

 and worse descrij)tion of " Stripsyplier sordidus" which comes from Senegal. 



Of the section Zebr^ei we have one species at the Cape. 



Sp. 3. (Trichinus) Campulipus Zebra, Klug. 



StripsypJier Zebra, G. P. p. 98. tab. 12. fig. 1. 

 Note. I may here observe that the Stripsypher called by Gory in his text the S. Umaculatus of 

 Schonherr, and in his plates 8. Q-maculatus is neither. It is called by Schonherr Trichim G-guttatus. 



Sub-genus 3. Trichius, M'L. 

 19. This may be known from Campulipus by having a much shorter palpiform process to 

 the termination of the maxillse, as well as by the podex being in general more covered by the 

 elytra. It has also a more convex form, and thus it may be distinguished from the sub-genus 

 Valgus, as well as by its longer elytra. Trichius haunts flowers, and may be found in 

 Great Britain. It is the sub-genus which passes off to the GlaphyridcR. 



SECTIONS OF TRICHIUS.

a long pencil of hairs, ' illary palpi grooved. Inhabit Africa and Asia. 



20. Under the name of " Legitimi," I have included Mr. Kirby's two sections, "Legitimi" 

 and Trichini, which last he now terms a sub-genus. The evanescent difference between 

 these two groupes of the reverend gentleman appears to be of a very low order, and probably, 

 therefore, only indicates sub-sections. Indeed, it chiefly consists in his Trichini being 

 nitid and aeneous, and his Legitimi not. However, Mr. Kirby thinks he can discover some 

 slight difference in the last joint of the palpi. The type of the section I have termed Legitimi 

 is the well-known Trichius fasciatus of Fabricius. Mr. Kirby makes the type of his section 

 Aleurosticti to be Trichius nobilis of Fabricius. This last section is, therefore, identical 

 with the groupe called Gnorimus in the " Encyclopedic" by MM. Lepelletier and Serville. 



21. Under the name of Geometrici, I have included Mr. Kirby's two sections Archimedii 

 and Enclidii, because there is, in my opinion, no sufficient difference between them to 

 entitle them to be made distinct sections of the sub-genus. They may, however, ultimately 

 prove to be distinct sub-sections of the section Geometrici. I consider the type of the 

 Geometrici to be Trichius delta of Fabricius. 



22. Of the section Tetrophthalmi, as distinguished by Kirby, we have among the insects 

 collected by Dr. Smith, the following species.
