ZOOLOGY. 613 



Fam. 9. Perfect Beetles Enlkafer or Lamellicornes, 

 Mostly large, convex and short bodied Beetles with 

 large thorax, broad head, lamellated antenna! clubs, spi- 

 nose tibia? and pentameral tarsi. Their habitation is in 

 dung or under the earth, where they live in the larval 

 state frequently for years before they change; some 

 Chafers eat also leaves of trees and flowers. They are 

 distinguished by their striking size and singular forms, 

 being mostly furnished with horns on the thorax or 

 head. I do veritably believe that they may be generally 

 interpreted as being the highest organized beetles and 

 members of their class, although they are generally 

 placed or arranged midway between the lower forms, 

 while the Sand- and Laufkafer are esteemed the most 

 perfect. 



Tabular Co-arrangement. 



The Dermatozoa now admit of being co-arranged in 

 the following manner, from which their three Cardinal 

 relations of Proximity, Repetition, and Serial analogy 

 or Parallelism, admit of being distinctly recognized.
