the editor of a late edition of Drury’s work. Fabricius, Olivier, Lamarck, and Klug, have all confounded 
the two foregoing species, and made them one, although the two first entomologists must have seen both 
specimens, although the original describer suspected them to be distinct ; and although they will to the 
eye of any modern entomologist who inspects them, appear totally different from each other. The 
bifurcation of the extremity of the clypeus in the male, is of a different form from that of Goliathus 
Drurii , inasmuch as the latter is curved backwards so as to resemble the Greek letter Y, whereas in 
G. giganteus it resembles more the letter Y. The marking, colour, and size, are also so different, that 
one is really amused to find King, in a late publication,* gravely laying down a theory to account for the 
two unique insects of Drury’s Collection forming only one species. It is true that he never saw them ; 
hut he read in Drury’s work that the former of these species ( Goliathus Drurii ,) was found dead, and 
floating on the surface of the river Gaboon. Catching at this fact, in the tc Verzeichniss von Thieren und 
Pflanzen ,” which were collected by Adolph Erman in his voyage round the world, King says that the 
identity of the two species being fully proved by Drury’s figures, which represent the clypeus porrected 
in both beetles, and the colouring of the thorax not essentially distinct, no regard ought to be paid 
by us to the very different colouring of the elytra, since the specimen figured by Drury, vol. i. t. 31., 
having been found dead in the water, may have lost its original white covering, and may thus appear to us 
now of a brown colour. Such reasoning is certainly ingenious, but the colouring of the thorax is very 
distinct, and, I will venture to say, that the clypeus will be found bifid and porrected even in the male 
of G. regius when known ; and besides, I have pointed out sufficient differences to make it certain that 
Drury was right when he suspected his two unique specimens to belong to different species. I am not 
much inclined to adopt Lamarck’s trivial name “ giganteus ,” because he applied it to both species, 
G. Drurii and this ; nor can I adopt Klug’s trivial name “ imperially” for, in fact this is in like 
manner applied by its author to an imaginary being, made up of the two foregoing species united, 
which, be it observed, neither he nor Lamarck ever saw. In my specimen of G. giganteus there are two 
small black spots on the hinder part of the thorax which is quite white, the two middle vittae being 
abbreviated. In the other specimen which I have seen, the two middle black vittse reach to the hinder 
margin of the thorax, and the two small black spots above mentioned become connected with the other 
vittae on each side. Mr. Kirby, in his Introduction to Entomology, vol. iv. p. 506, alludes to some 
private letter of mine to him, in which mention was made of Goliathus giganteus. I suppose, there- 
fore, that at the time of writing that letter, I assigned the name which Lamarck has given both to 
G. Drurii and this, to the latter species alone.

Note. This insect, like the last, is truly from Africa, as Professor Klug perceived. The first 
describers of it, however, made it to be an American species, and so dubbed it “ a Cacique. The 
original specimen is said to be at Glasgow in the Hunterian Museum. I believe Mr. Hope possesses one 
in spirits, and I have seen another in the National Museum at Paris. Of this last we have an excellent 
figure given by M. Gory. Goliathus giganteus comes exactly between this species and G. segius , for if 
we look at the marking of the thorax, we find G. giganteus to agree with G. Cacicus, and if we look at
