240 NATURAL ARRANGEMENT OF INSECTS. 



the five primary divisions of the Cetoniadae, by com- 

 paring them with the higher orders of insects, and the 

 more remote groups of the vertebrate circle, we need 

 not repeat the same details in this place. If the 

 above comparison between the Cetoniadce and the Sea- 

 rabcBidce is really natural, it follows that the latter 

 possess precisely the same analogies to all other groups, 

 as do the former. Hence it is only necessary, in this 

 place, to assemble the names of the different groups 

 which have been thus compared, that the eye may at 

 once embrace the whole.

It thus appears that the Cetoniance pre-eminently re- 

 present the most typical of the coleopterous tribes, the 

 most perfect of the orders of winged insects, and the 

 most highly organised of vertebrate animals : the 

 Rutilince, by their large jaws, find their representatives 

 not only in the Geotrupinae, but in the voracious Cicin- 

 delidcBythe -predatoriidHemiptera, and the beasts of prey: 

 the gigantic Dynastince and Megasomince stand as pro- 

 totypes of the great Capricorn beetles, and the bulky 

 ruminating quadrupeds. The most striking analogies 

 are merely glanced at, that the philosophic entomologist 

 may elaborate innumerable others which result from 

 this table. 



(215.) On the three aberrant families of this tribe, 

 the Lucanidce, the Buprestida, and the Hydrophilidce, 

 our notices must be brief: they are greatly inferior 

 in point of numbers to the typical groups, and no
