32 INSECTA. 



and fellow traveller of the late Delalande, and who has returned to 

 the Cape of Good Hope, has lately sent us a species which is not 

 larger than the C. gagaf.es, which it also resembles in its colours, 

 and which presents ail the characters of a Goliath. The C. geotru- 

 pina of M. Schoenherr is perhaps also congeneric. The thorax in 

 Goliath is less round and pointed than in Inca. The anterior thighs 

 are not dentated, and there is no emarginalion in the inner side of 

 their tibiae*. 



In the third division of the Melitophilii, a section corresponding 

 to the family of the Cetojiiidce, Mac Leay, the sternum is prolonged 

 more or less into an obtuse point between the second pair of legs ; 

 the epimera or axillary piece is always apparent above, and occupies 

 all the space that separates the posterior angles of the thorax from 

 the base of the elytra; the thorax usually becomes Avidened poste- 

 riorly, and has the form of a triangle truncated anteriorly or at the 

 point f. The mentum is never transversal, and its superior edge 

 is more or less emarginated in the middle. The terminal lobe of 

 the maxillae is silky or penicilliform. The body is almost ovoid, and 

 depressed. 



This division comprises the genus 



Cetonia, Fab., 



With the exception of the species that belong to the preceding 

 subgenus and to Rutela ];. 



In some, the thorax is prolonged posteriorly in the form of an an- 

 gle, so that the scutellum totally disappears. They form the genus 

 Gymnetis, Mac Leay, Hor. Entom., I, p. 152. Several are found in 

 America. Some inhabit Java, and the eastern parts of Asia, in 

 which the thorax is similarly prolonged, but where the scutellum, 

 although very small, is still visible §; the mentum is also more deeply 

 and angularly emarginated, and the last joint of the labial palpi is 

 propcrtionably longer. The epistoma is more or less bifid. There 

 are others in New Holland and the East Indies in which the epistoma 

 is still bifid or armed with two horns in the males, but the body is 

 proportionally narrower and more elongated, the abdomen consider- 

 ably narrowed posteriorly, even almost triangular, and the antennal 

 club considerably elongated — they compose the genus Macronota of 



* See Encyc. Method., art. Scarabeides ; the Hist, des Anim. sans verteb., Lam.; 

 the Observ. Eatom., Weber, and Lin. Trans., XII, p. 407, -vihere M. Kirby describes 

 two species. There is an Insect in Java, that at a first glance appears to be a Go- 

 liath, and which Messrs. Lepeletier and Serville have considered as such ; but it has 

 all the essential characters of a Cetonia ; the thorax is merely rounded and narrowed 

 posteriorly. The male has a bifurcated horn on the head. 



t Almost orbicular in some, as in the C. cruenta, Fab. ; C. ventricosa, Schoen- 

 herr, &c. 



M. Chevrolat, possessor of a splendid collection of Coleoptera, among which are 

 several from that of Olivier, has shown me a species found in Cuba by M. Poe which 

 has the air of a Trichius, but the axillary pieces and sternal prolongation of the 

 Cetoniae. Certain species of this last genus — C. cornuta. Fab. — have the thorax fur- 

 nished with a small horn, and at the first glance resemble Scarabsei.
