CLASSIFICATION OF INSECTS. 



Since insects^ are so important to teachers and 

 every text-book deals with them from a systematic 

 point of view, we have been obhged to a certain ex- 

 tent to do the same in order to justify the classifica- 

 tion here adopted, and to place before more advanced 

 students and readers the principles underlying our 

 arrangement. Dr. A. S. Packard in his Entomology 

 for Beginners has wisely opened the way for the 

 adoption of Friederich Brauer's classification. We 

 have not been able to follow precisely in the footsteps 

 of any one author, but have quoted freely from 

 Packard's books, from Comstock's Introduction to 

 Entomology, and Brauer's Systematische zoologische 

 Studien? Although the introduction of sixteen orders 

 of insects seems to make the study more compKcated, 

 it is, in reality, a very marked advance towards sim- 

 plicity. Teachers need not use all the types ; but
