CETONIIDJE OF AFRICA.

and the four hind tibiae in this sex are also without a central spine 
on the outside. The metasternal process is conically porrected, and 
at its extremity appears a slight channel, separating the scarcely 
visible portion of the mesosternum. 
Mr. MacLeay in his observations on this group was unable to 
state whether plantulse and pseudonychise exist in all the feet, in 
consequence of his specimens being mutilated. I may, therefore, 
mention that a rather strong plantula exists between the tarsal 
ungues of all the feet in both sexes, and that it is terminated by 
two or three very short bristles, which are often broken off, even 
in all the feet. In noticing the figures of the so-named Goliaths 
regius and princeps, Mr. MacLeay states that no allusion is made 
by their respective authors to the existence of plantulm ; although 
they are distinctly shown, both in Dr. Klug’s and my figures, of 
those insects. The four posterior tibiee in both sexes are fringed 
throughout the hinder margin with fine soft fulvous hairs, which in 
the middle feet are longest at the base; Mr. MacLeay also describes 
the males as having “ the anterior tibke thus lined only half-'way,” 
which is not the case, the inside of these tibiae having, at the base 
within, a patch of fulvous velvet-like plush of a texture totally un¬ 
like the long soft marginal hairs of the other feet; a similar patch, of 
the same texture, also existing at the base of the other tibiae within. 
It has been long observed that the Cetoniidae, during flight, do not 
erect the elytra, but keep them horizontal, and I have observed a 
peculiarity in the structure of the scutellum, which has an evident 
effect in this peculiarity, each side of the scutellum being suddenly 
and deeply deflexed, which I have found (by the examination of 
individuals moistened in spirits of wine), forms a strong line of 
resistance against the sides of the inner margin of each elytron, when 
I have attempted to elevate them perpendicularly. 
9 The species of this genus (as first restricted in Mr. Hope's ‘ Coleop- 
terists’ Manual’ to the giant types of the family possessing the cha¬ 
racters above mentioned), are peculiar to Western tropical Africa.
