50 POPULAE ENTOMOLOGY. 



The description of the family distinctions in this chapter 

 are principally taken (though much simplified and abridged) 

 from the valuable works of Westwood_, which I would 

 strongly recommend, together with those of Kirby and 

 Spence, to the notice of students who wish for more ex- 

 tended information; the former treating with great clearness 

 on the difiicult subject of classification; the latter, parti- 

 cularly that known as the ' Introduction to Entomology/ 

 detaihng in the most lively and interesting manner, the 

 natural history, beauty, and peculiarities of this portion of 

 animated nature. To the latter work I am deeply indebted 

 for much useful and entertaining information, and the fre- 

 quent allusions to it in this little volume will, I hope, lead 

 my readers to a perusal of its pages, affording them delight 

 and profit by its varied and circumstantial history of Insect 

 Life.
