132 ON THE GOLIATHIDEOUS CETONIIDA 
The species to which our attention is now directed are the 
most aberrant of the Goliathideous Cetontide. They have lost the 
characters of the prothorax broadest across the middle, and the 
pluridentate and porrected upper maxillary lobe of Goliathus, 
Narycius, Cyphonocephalus, Mycteristes, and Phzedimus; and the 
dilated prothorax and elongated fore legs with 3-dentate tibize of the 
males of Dicronocephalus. With this last, however,-they agree 
in possessing a simple upper maxillary lobe. 
The remaining groups of the Asiatic Goliathideous Cetoniidze 
may be thus arranged. 
Mesosterni processus brevis latus.

** Clypeus ¢ bicornutus ; . . Diceros bicornis, §c. 
As the toothing of the anterior tibize affords one of the most 
satisfactory characters for the discrimination of the group of 
Goliathideous Cetoniidee, and as the different sections founded 
thereon, especially amongst the African species, have received 
generic names referring to the structure of the clypeus, I propose 
in this place to distinguish those species with bidentate tibize in 
the females, and with tibiz either simple, or exhibiting a slight 
indication of bidentation in the males, and which, moreover, have 
generally an elongated mesosternal process, and the fore feet not 
materially unequal in size in the two sexes, under the name of 
HETERORHINA,§ 
A name selected from the very variable structure and armature 
of the clypeus. If, indeed, this character were allowed to prevail 
* There is no African group precisely analogous to this, in the form of the clypeus ; Eudi- 
cella, however, represents it in respect to the internal serration of the fore tibize of the males. 
t Represented in Africa by C. africana, stigma, &c. 
{ Represented in Africa by C. suturalis. 
§ As this group is quite different in its construction from those of Gnathocera of Gory and 
Perchéron, or Coryphe of Mac Leay, I have applied a new name to it. Mr. Kirby’s excellent 
name of Chlorocala would have been adopted had not the group been intended to comprise 
species which are neither green nor beautiful.
