foot of the statues of their heroes, to express manly and martial 

 virtue, exempt from all weakness, a virtue which, according 

 to them, appertained to powerful minds — to men truly illus- 

 trious. 



The perfect insect of the scarabseus, like most of the tribe, 

 is not often in a situation immediately after its birth to make 

 use of its organs. It has need to fortify itself, which often 

 requires a tolerably long time. The internal organization 

 has undergone great changes. The long intestine, all of 

 one width, is no longer observed. The tracheae are all vesi- 

 cular. 



The insects of the sub-genus Hexodon, have some rela- 

 tions with melolontha, cetonia, and especially rutela. They 

 frequent trees and shrubs, and feed upon their leaves. The 

 larva is not known, but it probably differs but little from 

 that of melolontha, whicli we shall describe below. 



In consequence of the singularity of the insect, and the 

 rarity of the tract in which it was originally published, we 

 have deemed the insect described by Mr. Francillon, under 

 the name of the kanguroo beetle, or scarabasus macropus, to 

 be very worthy of an introduction into our illustrations. 

 This insect is supposed to have come from Potosi, in South 

 America. It is of a bright green colour above, with the 

 elytra smooth, and golden and copperish beneath, with the 

 hind legs incrassated to a most extraordinary size. 



We believe this unique insect is in the collection of Mr. 

 Macleay. As an inhabitant of South America there can be 

 but little doubt, since M. Humboldt has discovered a species 

 very like it in form in Peru, which M. Latreille has described 

 in a magnificent work published by himself and M. Hum- 

 boldt, under the name of melolontha chrysochlora. This 

 species is of a brilliant golden green, with the breast, the 

 underside of the abdomen, and the femora and tibias of the pos- 

 terior legs of a reddish copper colour. The head, thorax, seg-
