114 STUDY OF 



which the fashionable orismology of tliis iilte-' 

 resting science is daily heaping upon the un-» 

 learned. 



Young entomologists are well aware of the 

 advantages they derive from the modern division 

 of insects into the two classes, Mandibulata and 

 Haustellata; and few persons will deny, that, 

 for a great proportion of students, simple ar- 

 rangements are very desirable ; how far they are 

 consistent with a proper knowledge of the sub- 

 ject is a more difficult question. 



In the study of Ornithology, much conveni- 

 ence has arisen from separating birds into the 

 two grand divisions of land and water birds, with 

 the intermediate tribe of waders ; I am not aware 

 that any similar attempt has been made in ento- 

 mology, but, if it be practicable, I submit, with 

 much deference, that it would be of great use.* 



♦ Since this paper was read, I have discovered that Aldrovandus, 

 in his voluminous work published in 1602, divides insects into 

 terrestrial and aquatic ; and Wolfgang Fantzius, in his Historia 

 Animalium Sacra, has a distribution of insects into aerial, aqua- 

 tic, and terrestrial. Scopoli, in 1777, divided his proboscidea 

 into terrestrial and aquatic, and the coleoptera into those inha- 

 biting water, and those the land; but I am not aware that any 

 modern author has adopted similar divisions.
