some new Coleopterous Insects. 37 
regards its affinities. Beyond the differences pointed out between 
the Goliathus rhinophyllus and the true species of Goliathus by Mr. 
Mac Leay, I may observe that, in all the species of Goliathus I 
have been able to examine, I have found the process of the metas- 
ternum remarkably broad, and, in some, extended almost to the 
base of the anterior pair of legs, whilst in PAzlistina, or Mycteristes, 
this process is narrow, and but slightly prominent. 
Though, however, the Mycteristes Cumingit approaches most 
nearly to the G. rhinophyllus, there are several points of distinction 
worthy of notice, and which perhaps might be regarded as sub- 
generic,—in which case I should propose that the name Phedimus* 
be applied,—the horn on the head and that on the thorax in JJ. 
Cumingii are much stouter ; that on the head is shorter, and has 
a protuberance in front, and that on the thorax is distinctly forked 
at the extremity, and is perfected with a flattened projecting pro- 
cess beneath: the legs are stouter—(I am comparing the males 
together)—and the anterior tibize are not notched externally; the 
tarsi are shorter, and the claws are much longer, and there are 
no brushes of stiff hairs on the under side of the tibize, —these 
velvet-like pads are found on all the tibize (of the male only), 
and extend from the tip rather more than half-way towards the 
base. 
The colouring of this insect is remarkably brilliant, and change- 
able according to the light; in one position it presents a splendid 
golden-green tint, in another it presents a yellow cast, and appears, 
as it were, washed with golden green: this yellow hue however is 
not observable on the head and thorax, whilst on the other hand 
it is most conspicuous on the thighs and tarsi. In these latter I 
find all the joints tipped with blackish, and with a spot of the 
same colour on each side ; the tibia of the female are deep green, 
excepting at the tip, where a yellowish hue is observable; the 
tarsi are also deep green, but the terminal joint of those of the 
hind legs has the apical half yellow. The thorax and scutellum 
are smooth, the elytra are covered with minute confluent punc- 
tures; the body beneath is thickly punctured, and covered nearly 
throughout with minute, decumbent, yellow hairs. 
The head is thickly punctured in the female, and the clypeus is 
distinctly emarginated ; the thorax is also distinctly punctured ; on 
the disc, however, there are but few of these impressions ; an 
impressed line runs parallel with, and close to, the lateral margins, 
and near this line are a few indistinct reddish spots; some scat- 
tered hairs are observable on the margins of the thorax, and there 
are a few on the upper surface, and likewise on the elytra.
