ON THE GOLIATHIDEOUS CETONIIDA: OF ASIA. 
Part Il. 
Tur first and second figures of plate 33, representing the female 
of Narycius opalus and the male of N. (C.) smaragdulus, with their 
details, have already been described in the former paper on the 
Asiatic Goliath beetles (pp. 114, 115), as has also Rhomborhina 
clypeata, described in page 119, where it was accidentally referred 
to plate 33, fig. 3, instead of plate 34, fig. 3. I now proceed, there- 
fore, with the illustrations of the remaining species, all of which 
(with the exception of those composing the group named Diceros) 
enter into the genus Gnathocera of Gory and Perchéron. 
A genus thus named was first described by the Rev. Dr. Kirby 
in the 14th volume of the Linnean Transactions (p. 571), the 
description, especially of the maxillee and genze, is however applicable 
to a very different group of African Cetoniidee, typified by Cetonia 
elata, Fabr. Considerable confusion has, indeed, subsequently 
arisen in the employment of this generic name, which has been 
attributed to indolence, or even to a still worse principle*. The 
confusion, however, appears to me to have originated from a 
misapprehension of the note appended by Mr. Kirby to his generic 
description. After stating that the type of the genus was the 
Cetonia vitticollis, Latr. MS., e@idds, “‘ Regio, Africa. Cognate 
species, Cetonia africana, elegans,” &c. ; which would naturally 
lead to the opinion that the last-named species were regarded as 
congenerie with the type. That such, however, was not his view, 
is evident, not only from the Indian C. elegans being given as one of 
these cognate species, but also from the appendix to the Introduction 
to Entomology t; wherein the C. vitticollisis given under Gnathocera, 
* Tn this, as in numerous other respects, Mr. Mac Leay charges Messrs. Gory and Perchéron 
with blindly following Dejean, whereas the first part of their monograph (which contained an 
entire synopsis of the genera and species) appeared in 1833, in which year only was com- 
menced the 2nd Edition of Dejean’s Catalogue. It is rather amusing to compare such a 
charge with the observation of Count Mannerheim upon the same authors (Obsery, critiq. sur 
la Monog. des Cétoines), ‘* Ils s’obstinent encore plus dans /eur principe de ne pas adopter les 
noms de Dejean.’’ We are involuntarily reminded by these conflicting charges of the fable 
of the Old Man, his Son, and his Ass. 
+ The evident meaning of the word Gnathocera, as employed by Kirby, is an allusion to
