ASIATIC CETONIIDAJ. 
It is impossible on referring to the former of these two sections, 
not to be convinced that the gigantic Goliathi of Africa are its 
types. They exhibit in the highest degree the male cornuted 
character of the section, but they are distinguished by two 
characters which are not found in the majority of the group— 
namely, the pronotum widest across the middle, and the upper 
lobe of the maxillee dentated ; they are, however, found in several 
eastern forms, with which our review will naturally commence.

As originally described by M. Dupont, this genus comprised two 
species N. opalus and N. olivaceus, both from Madras; but, as 
already alluded to in pp. 5 and 70 (note*)-), they are but the sexes of 
a single species, for which the name of N. opalus should be retained 
as being that of the male. 
By the kindness of M. Dupont, during my recent visit to Paris, 
(May and June, 1842,) I have been enabled to study this most 
interesting species in detail. The male *, of which an outline, 
copied from Guerins “ Magasin,” was given in my plate 1, fig. 5, 
is distinguished by two long and very robust horns in front of 
the head. The mandibles (Plate 33, fig. 1 a) have the horny blade 
sharp and angularly dilated in the middle on the outside; the 
maxilke (fig. 1 b and 1 b f) have the upper lobe short, and much 
curved, with the apex 3-dentate, and the outside strongly hairy ; 
the inner lobe is produced at the tip into an acute point, and the 
palpi are short; the mentum (fig. 1 c ) is short and broad, much 
narrow r ed in front and deeply emarginate with the labial palpi very 
short. The pronotum is broadest across the middle. The meso- 
sternum (fig. 1 rf, 1 e) is conical, acute, and porrected; the anterior 
tibiae (fig. 1 f) are rather broad, with one strong tooth on the outside 
below the acute apex ; the ungues (fig. 1 g) are furnished with a 
very short bisetose plantula, and the abdomen is channeled beneath. 
The femalef (Plate 33, fig. I, copied from Guerin’s figure) is more 
robust than the male, with the head produced into two short horns 
—a most singular character; the maxilke are formed as in the 
male ; the fore tibiae (fig. 1 li) are externally furnished with three 
obtuse teeth; the middle and posterior tibiae are much more 
strongly toothed than in the male; the abdomen is not channeled
