ON THE GOLIATHIDEOUS CETONIIDiE OF AFRICA. 
PART I. 
There is scarcely any group of insects which more fully shows 
the great increase of our modern stores of novelties than the 
Goliathideous Cetoniidse, out* knowledge of the number of species 
of which having been more than doubled during the last five years. 
Having in the 8tli and 9th numbers of this work given a complete 
revision of the Asiatic species of the group, I propose in this and 
the following number to treat the African species in like manner, 
having been favoured, from several of our most extensive collections, 
with the loan of a number of fine unfigured species. I am further 
induced to this by the circumstance of the remaining insects of this 
group being confined in their geographical range to Africa * 
(including Madagascar), whereby a complete revision of the group 
will have appeared in this work; and because the insects of 
Africa are at the present time more particularly the subject of my 
entomological study ; having undertaken, at the request of the 
Rev. F. W. Hope, to prepare a report on the state of our know¬ 
ledge of African entomology, other gentlemen having in like 
manner undertaken other geographical districts, whereby we may 
hope to obtain a series of papers, which cannot fail to be of very 
considerable value. 
The typical genera of this group, as already noticed (ante, p. ] 14), 
are distinguished by two peculiarities, which are not found in the 
majority of the group—namely, the sub orbicular form of the protho¬ 
rax, and the dentated upper lobe of the maxillae. Here belong the 
two following African genera; 'which are at once distinguished 
from their Asiatic analogues, Narycius, Cyphonocephalus, Mycte- 
ristes, and Phsedimus, by their want of metallic colours, the more 
* With the exception of the Brazilian Yncae (which Burmeistcr has satisfactorily shown to 
belong to the Trichiideous section), and the Mexican Goliathus Hocpfneri, G. aud P. 
(Isclmoscelis H. Bunn.) a very interesting insect, of which only the cornu ted male has been 
observed. Dr. Burmeistcr, as alieady stated (p. 70, note +), at first considered it as nearest 
allied to Ischnostoma, but lie is now of opinion that it ought to bo introduced into the Goliathi¬ 
deous group. From a careful examination and dissection of the insect, which I made whilst 
in Paris in the past summer, 1 am not prepared to admit this relationship.
