58 BRITISH BUTTERFLIES. 



ruled varying in distance according to the breadth of 

 the butterflies, and small labels should be pinned down 

 at the foot of each species giving its specific name ; the 

 name of the genus being placed at the head of the/rsZ 

 species of the genus. The names of the families and 

 sub-families under which the genera are classed are also 

 generally given in their respective places. 



I have in this little work followed the system of 

 classification used in the public collection of British 

 butterflies at the British Museum, which seemed to me 

 more intelligible and natural when applied to our very 

 limited number of butterflies, than did the system of 

 Doubleday adopted in the great world-wide collection 

 which exists in the private entomological room, of the 

 British Museum. 



The following table gives the first-mentioned arrange- 

 ment of all the British species under their respective 

 genera, sub-families, and families. The most authentic 

 of the reputed species are also here inserted in their 

 proper places.
