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

 of the maxillae is silky or pcnicilliform. 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(l). 



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(2); the mentum is also more 

 deeply and angularly emarginated, and the last joint of the labial 

 palpi is proportionally 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 

 considerably narrowed posteriorly, even almost triangular, and the 

 antennal club considerably elongated they compose the genus Ma- 

 cronota of Wiedemann. These sections however can only be con- 

 sidered as established, when the numerous species of the genus Cetonia 

 of Fabricius have been particularly studied. 



Those of Europe are provided with a scutellum of an ordinary 

 size. Such are the 



C. aurata; Scarabseus avralus, L. : Oliv., Col., I, 6, i, i. Nine 



lines in length; a brilliant golden-green above, cupreous-red 



beneath; white spots on the elytra. Common on flowers and 



frequently on those of the Rose and Elder. 



C. fastuosa, Fab.; Panz., Faun. Insect. Germ., XLI, 16. 



Larger than the aurata; immaculate, uniform, golden-green; 



tarsi bluish. South of France. 



C. stictica; Scarab, stlcticus, L.; Panz. , lb., I, 4. Five lines 



in length; black, somewhat pilose, with Avhite points; those on 



the venter arranged in two or three lines, according to the sex. 



Very common on Thistles(3). 



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

 the Cetonise. Certain species of this last genus C. cornuta, Fab. have the 

 thorax furnished with a small horn, and at the first glance resemble Scarabxi.
