ON THE CETONIIDiE OF SOUTH AFRICA. 



49 



The following Cape species belong to the third sub-section : — 



Sp. 47. (Cetoninus) Cetonia balteata, Degeer. 



Scarabceus balteatm^ Degeer, vii. 642. tab. 48. fig. 4. 

 Cetonia controversa, G. P. p. 246. tab. 46, fig. 6. 

 Note. I do not allude here to Schonnherr, because his " Synonymia Insectorum" is altogether wrong 

 with respect to the species of this particular section Polybaphece. 



Sp. 48. (Cetoninus) Cetonia discoidea, Fab. 



Cetonia discoidea. Fab. Syst. Eleuth. 2. 158. 116. 

 Cetonia velutina, Oliv. tab. 12. fig. 114. 



G.P. p. 246. tab. 46. fig. 5. 



Cetonia Jlammea, Zool. Journ. vol. 2. p. 237. tab. 9. fig. 2. 



90. As this last-mentioned section of the sub-genus CetoninusheKxs a resemblance in form to 

 Diplognatha, and represents the genus Macrominus, so the section to which we now pass bears 

 a strong resemblance to Lomaptera in the genus Gymnetinus which is here represented. This 

 section I have therefore called Gymnetideje, and it belongs typically to Madagascar, although 

 found also in New Holland. There are several known sub-sections ; but as they present no 

 Cape insects, I need not detail them here. I shall only say, that the Cetonics GymnetidecB, by 

 their beautiful form and polished flat elytra, with serrated sides, by their often cloven clypeus, 

 long maxillse, and emarginate mentum, close the circle of the genus Cetoninus by uniting them- 

 selves with the sub-genus Schizorhina, and thus forming the junction between it and the sub- 

 genus Cetonia. 



91. By means of Cetonia cincta of Donovan, we arrive at the only remaining section of 

 Cetonia, which I have called Typice, not because they are typical of the sub-genus, but 

 because they represent the genus Cetoninus, as it were, par excellence. This section is so 

 numerous as to offer sub-sections, which, however, as may be expected, depend on very 

 refined and even evanescent considerations. Perhaps, however, 1 have not yet been able to 

 seize the true characters of distinction ; and, indeed, it is of little consequence, provided I can 

 explain the series of affinity, which appears to me to be as follows : — 



f 1 Black. Type, C. morio, Fab. 



B. — Typically European. <j 2 Viridiaeneous. Type, C.fastuosa, Fab. 



[^3 Yiridiseneous spotted with white. Type, C. aurata, Lin. 



^ . ^4 Green with white or yellow lines. Type, C. aulica, Fab. 



"'^^ ■ \J, Yellow or black spotted with yellow. Type, C. sinuata, Fab. 



92. As we have no species from the Cape of the three first sub-sections, I shall begin with 

 the one which is here numbered the fifth, and designated "Nigrse flavomaculatae vel flav«." 

 To this beautiful African groupe belong the following described species : — 1. Cetonia punctato- 

 marginata, Degeer ; C. impressa, G. P. ; C. inscripta, G. P. ; C. marginata, Fab. ; C. 

 postica, G. P.; C. fimhriata, G. P.; C. monacha, G. P.; C. fasciata, Fab. {Savigmj, 

 G. P.); C. olivacea, 01.; C. interrupta, Fab., &c. &c. ; and also the following species 

 brought from the Cape by Dr. Smith : — 



Sp. 49. (Cetoninus) Cetonia sinuata, Oliv. 



Descr. Cetonia nigrofusca, thoracis elytrorumque margine, thoracis maculis quinque, scutelli 

 duabus, elytrorumque quatuor fiavis, thoracis maculis marginalibus elytrorumque duabus 

 nigro-fuscis, corpore subtus nigro.
