CETONIIDA OF AFRICA. 167 
the Princeps of Hope is the female of Cacicus. The Gold Coast 
would seem to be the locality of Drurii, andt he Grain Coast that 
of the Zorquatus and Cacicus.” 
The tarsi of the males of this species are much more slender than 
‘in G. Drurii. 
The largest specimen of the male of G. Cacicus which I have seen 
measures three inches and a half in length, including the horns of 
the head, whilst some are at least one-third shorter. The smallest 
female which I have seen measures two inches and a half in length, 
the elytra at the base being one inch and one-third in width. 
In some specimens of the female the two lateral fulvous marks on 
each side of the prothorax are united, and broader than in the 
specimen figured by me in Mr. Hope’s Coleopterists’ Manual, and 
in others the elytra have the pearly portion much more extended, 
leaving only a dark patch at each shoulder, and a large triangular 
basal spot extending half the length of the elytra. 
Africa possesses, at least as far as known at present, no species 
analogous to the Asiatic genera, 
Narycius and Cyphonocephalus, in having the sides of the head 
alone produced into horns, and the maxille multidentate. 
Mycteristes and Phedimus, in having the front of the prothorax 
cornuted, and the maxillz multidentate, or 
Dicronocephalus, in having the prothorax broadest. across the 
middle, with the maxille edentate. 
We therefore now proceed with that section of the subfamily 
which possesses a trapezoidal prothorax, broadest at its hinder 
angles, and a simple terminal lobe to the maxilla. The types of 
this group nearly rival in size the great Goliaths; they are, how- 
ever, for the most part much more brilliantly coloured ; the elytra 
are much broader at the base than behind ; the body is very much 
depressed, and the prothorax has the posterior margin slightly 
emarginate in front of the scutellum. The fore-feet, in the males 
of this section, are considerably more elongated than in the oppo- 
site sex. The majority of the species of this section possess a short 
sternal process between the middle feet, and the species are at 
once distinguished from their Kastern analogues, by a peculiarity in 
the formation of the sternal process between the middle feet, which
