PLATES XXXIII, XXXIV, XXXV, and XXXVI. 
ON THE GOLTATHIDEOUS CETONIIDjE OF ASIA. 
Part II. 
The first and second figures of plate 83, 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. 8, instead of plate 84, 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 Percheron. 
A genus thus named was first described by the Rev. Dr. Kirby 
in the 14th volume of the Linnsean Transactions (p. 571), the 
description, especially of the maxiltee and gense, is however applicable 
to a very different group of African Cetoniidse, typified by Cetonia 
elata, Fair. 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 vittieollis, Latr. MS., he adds, “ Regio, Africa. Cognate 
species, Cetonia africana, elegans,” &c. ; which would naturally 
lead to the opinion that the last-named species were regarded as 
congeneric 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+ ; wherein the C. vittieollis is given under Gnathocera, 
* In this, as in numerous other respects, Mr. Mac Leay charges Messrs. Gory and Percheron 
Tvith 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 Dejcan's Catalogue. It is rather amusing to compare such a 
charge with the observation of Count Mannerlieim upon the same authors (Observ. critiq. sur 
laMonog. des Cetoines), “ 11s s’ohstinent encore plus dans leur principe de ne pas adopter les 
noms de Dejean We are involuntarily reminded by these conflicting charges of the fable 
of the Old Alan, his Son, and his Ass. 
f The evident meaning of the word Gnathocera, as employed by Kirby, is an allusion to
