SEAKCHING FOR EGGS OF INSECTS. 311 



cially) tTie propriety of giving all insects, not actually noxious, 

 their liberty, if on examination they prove to be useless as 

 specimens. These remarks apply also to the case of hybernated 

 females. Many female insects, though unwilling to lay in con- 

 finement, may be watched at large, and the flowers and plants on 

 which they have from time to time rested, searched for their 

 eggs. 



In concluding this chapter, I feel that I might have said 

 much more upon nearly every section — ^have explained many 

 new " dodges," and so forth, were it not that the limit of space 

 has been reached. One thing, however, may be noted as an 

 omission, and that is the recommendation as to what books 

 should be procured by the young entomologist. This is so 

 difficult a matter — depending entirely upon the aim of the 

 individual — that I prefer to leave it an open question, merely 

 making the general statement that nearly all our advanced 

 systems are founded upon the labours of German and Erench 

 entomologists.*

 Book Circular," which he will send to naturalists if asked.
