THE majority of anglers will no doubt be Determina-

 I would recommend that the following pages 

 be passed over and reference made at once to 

 the coloured plates, which form, perhaps, the 

 most important feature of this book. 



For the benefit of the trout fisherman who 

 seriously wishes to identify not only the genus 

 but also the species of insects which his arti- 

 ficial patterns are intended to represent, I will 

 describe the system of examination which may 

 be adopted on entering into the study of the 

 families concerned. 



A few general remarks may not be out of 

 place. For the purposes of classification, the tlon ' 

 insect kingdom is divided into what are termed 

 Orders. Orders are sometimes divided into sub- 

 orders. These again are split up into Families. 

 In the Families are grouped various Genera, and 

 the Genera themselves contain species, which 

 individual insects represent. Insects showing 

 some slight difference from the type of an 

 unimportant character are termed varieties. 



An insect is, roughly speaking, divided into
