ON THE CETONIID^ OF SOUTH AFRICA. 



88. Of the fifth sub-section, which is also peculiar to Africa, we have the following 

 species : — 



Sp. 41. (Cetoninus) Cetonia adspersa, Weher.

 G. P. p. 297. tab. 57. fig. 7. 



Sp. 42. (Cetoninus) Cetonia dysenterica, n. s. 



Descr. Cetonia clypeo elongate apice angustato recurvo emarginato, capite thorace scapnlis 

 scutelloque nlgro-nitidis, elytris viridibiis nigro-llneatis, corpore subtus pedibusque nigris, 

 ano ferriigineo.

89. Let us now return to that Asiatic sub-section, the type of which is C. histrio of 

 Fabricius. From it we may proceed to that section of the sub-genus Cetonia, which answers 

 nearly, though not exactly, to a groupe which Mr. Kirby has indicated under the name of 

 Polyhaphes. If this learned entomologist had attempted to give his Polylaphes a character, 

 he probably would not have joined C. histrio with C. cequinoctialis ; but nothing is so easy as 

 to follow the indolent plan invented by M. Dejean of giving to groupes generic names unac- 

 companied by descriptions. I hold in utter contempt that privilege of naming for which 

 naturalists are so much in the habit of squabbling ; and, on the contrary, am always grateful 

 to those persons who kindly provide me with an unobjectionable word. Nevertheless, I am 

 bound to protest against any name that is published without a character ; since it ought not 

 to be of the slightest authority in the science. It certainly is not the individual placing two 

 Greek words barbarously in juxta-position who deserves the credit of discovering a genus, 

 but he who accurately distinguishes the groupe, to which that barbarous name is given, from 

 all others. With respect, however, to the beautiful groupe which Mr. Kirby has called 

 PoLYBAPHES, I am disposed to retain the name, and shall merely therefore say, in addition, 

 that I am acquainted with three sub-sections of it.
