PRE FACE 



The author of this little work lias endeavored to at- 

 tain in it two ends, /. (?., to prcj^arc, in the first place, a 

 guide to the observer of the life and structure of the 

 insect, and, in the second place, an outline or ground- 

 work lor the class room or lecture room work in this 

 department. 



It is by no means intended to be complete in itself, 

 and the interest to be awakened in this beautiful depart- 

 ment of natural science must be attained by the study of 

 the objects themselves, to which these pages are intended 

 to serve merely as an index. 



The illustrations of this work have been taken from 

 E. F. Staveley's British Insects, and were kindly fur- 

 nished the author by L. Reeve & Co., of London. 



The author is well aware that many faults, especially 

 of omission, may readily be found with this outline, but 

 his plea for that is, that his aim in its preparation was 

 to make an assistant to the. teacher and learner, and not 

 a complete work in itself.
