Long. 12 lines. 
Note. It is but just to Dr. Wallich, after whom I suppose this insect was named, to correct the 
mistake which M. Gory has made in the orthography of his name. I have both sexes in my col- 
lection, from Nepaul. In one specimen of the male, the upper tooth of the anterior tibia is evanescent, 
so as to make it appear externally sub-bidentate. 
Sp. (Cetoninus) Goliathus opalus, Dupont. 
Descr. Goliathus nitidus flavescens viridi-micans, thorace vage punctato viridi-ignescente, tarso- 
rum articulis apice unguibusque nigris. 
$ Clypeo antice cavo, bicornuto, cornubus productis triquetris supra baud dentatis apice 
antrorsum arcuatis.

Narycius opalus, Dupont, Mag. Zool. Cl. ix. p. 128. 
Note. In Guerin’s Magazine, M. Dupont gives the figure and description of an insect from Madras, 
which he places in a now genus, called by him Narycius and Naricius. He gives no distinct character 
to the genus, but describes two species, of which, although they are exceedingly close to each other in 
affinity, I suspect his Narycius olimceus to belong rather to the sub-genus Coryphe. The present species (his 
Narycius opalus) is curious, as being exactly intermediate betwoen Goliathus Wallichii, G. P., and 
those brilliant green Goliathi which form the beauty of the section which I have called Smithii. 
Thus do we return to those Goliathi with the description of which we commenced our observations 
on this rich and rare sub-genus. I must, however, before I leave the groupe, call attention to the 
curious analogy that exists between Goliathus opalus and Lamprima amea, and remark how the clypens 
in one takes the form of the mandibles of the other, making Latreille fancy that they were annectent 
genera. I need scarcely observe that the Goliathus opalus must not bo confounded with the Goliathus 
opalinus of Gory, which is a Coryphe. 
74. Of true Goliathi, I consider that the above-mentioned species may be accounted as dis- 
tinctly known. But we have now to return to the aberrant groupe of Goliathi Gigantei, and we 
may observe a Cape insect, which M. Gory has described under the name of Diplognatha concava, 
to present several points of structure held by it iu common with those gigantic beetles. Like 
them this insect has a three-horned clypeus, although the horns are here considerably modified, 
particularly the central one, which is short and trifid. The anterior tibiae are externally tri- 
dentate, as in the females of the gigantic Goliathi, but here they differ, in being tridentate in 
both sexes. The body is likewise convex. The thorax is rounded. The scutellum is sharp. 
The epimeron is prominent between the elytra and thorax. The mesosternum is short, broad,
