ON THE GOLIATHIDEOUS OETONIIDiE 
the mentum (fig. 8 c ), which is deeply emarginate. The femora are peculiarly coloured, being 
of a fine golden, fulvous, or opaline colour, with the inner edge of each shining green 
or blue. 
The colour of the species varies very considerably, the upper surface varying from golden- 
green to blue, slightly tinged with green, with the elytra rich lilac-purple, with a dark suture. 
Such individuals (one of which is figured in plate 30, fig. 7, from the collection of F. Parry, 
Esq.), I believe, constitute the so-called species Cetonia mutabilis, Hope (Syn., Nep. Col. 
supr. cit.), but they are structurally identical with the type of the species, except that the 
conical front of the clypeus is not so regularly truncate. 
Inhabits Nepaul and other parts of India. 
Species II .—Heterorhina Hopei (Plate 33, fig. 3, and details). 
Gnathocera Hope, Gory and Percheron, Mon. Cet. pi. 20, f. 4. 
This species has very much of the habit of the preceding, but differs from it in several 
important characters :—thus, the clypeus is entire and quadrate, with the lateral and front 
margin slightly elevated, and the crown of the head scarcely elevated in the middle. The 
antenna? have a club of moderate length. The fore tibia? are simple, whence I conclude the 
specimens examined to be males, although the abdomen is not channeled beneath. The 
maxilla? (fig. 3 a ) are rather short, with the inner lobe terminated by an acute, curved, horny 
point, and the upper lobe also curved and terminated by two sharp horny points ; the mentum 
is rather deeply notched in the middle of the front margin. The mesosternal process is very 
short and obtuse (fig. 3 b, 3 c). The hind tibia? are distinctly spurred below the middle, and 
the plantula? and pseudonychias are very distinct. 
The snecies varies very much in colour; some specimens in the collection of Nepalese 
insects presented to the Linnsean Society by General Hardwicke, being of a blue or purple 
tinge. The one now figured, from the collection of AV. AA r . Saunders, Esq., is of an intense 
fiery copper, tinged according to the play of light with golden green. 
Species III.— Hetororhina dives , Westw. (Plate 33, fig. 5 a, b, c , d , e , /.) 
Gnathocera Mac Leay, Gory and Percheron, Mon. Cet. pi. 19, fig. 2 (nec. Cet. Mac 
Leaii, Kirby).

The only specimen I have seen of this magnificent insect was in the museum of the Jardin 
des Plantes, where I found it arranged with the true Cet. Mac Leaii, with which it has also 
been confounded by Gory and Percheron, whilst Mr. Mac Leay (from confiding in their Mono- 
graphie) lias mistaken it for the C. pretiosa of Eschsclioltz. As it is from this specimen that 
my figures were drawn, I did not venture to extract the trophi. Tho head of the male has 
the sides produced into two long porrected, nearly straight horns, the tips being incurved (fig. 
5 a , head from above, 5 b, the same from the front. 5 c, the same sideways); the front of the 
clypeus is deflexed and broad (5 b) ; the crown of the head is furnished with a very broad, 
short plate ; the mesosternal process is long, narrowed, rather obtuse at the tip, which is 
slightly bent upwards (fig. 5 e and o f) ; the fore tibia? (5 d) are short and toothless, the 
hind ones have the rudiment of a spur below the middle; the pseudonychia? are scarcely dis¬ 
tinct, and the elytra have the tips strongly spined at the suture. As this species is well 
figured in the Monographic des C£toines, I have not thought it necessary to refigure it. 
Species IV_ Heterorhina Mac Leaii (plate 33, fig. 4, and details). 
Cetonia Mac Leaii , Kirby in Trans. Linn. Soc., vol. 12, p. 408, pi. 21, fig. 11 (nec. 
Gory and Perch).

Cetonia pretiosa t Esch. Entom. p. 23, No. 9, 1822 (nec. Coryphe pretiosa, Mac 
Leay). 
It is at once evident, from Esclischoltz's character a capitc spina incumbenti, clypeo reflexo 
bidentato,” given of his C. pretiosa, that it is identical with Mr. Kirby's insect. This lovely 
species has been recently brought from the Philippine Islands, by Mr. Cuming, in considerable 
numbers ; as it is not, however, figured in Gory and Perclieron’s Monograph, I have introduced 
it in the present work, and proceed to point out the characters of the sexes. The male has 
the clypeus more strongly bifid in front than the female, and the flattened horn on the crown 
of the head in the former sex is much more acute than iu the female, which has it obtusely 
rounded, or but slightly pointed (4 a, 4 b, head of male, 4/, head of female.) The mandibles
