One point which remains to be considered is the 

 number of specimens of each species to be placed in 

 the collection. Apart from the size of the cabinet and 

 the plent)- or scarcity of the \-arious species, liabilit}' 

 to var\- — a point which has been alread}' discussed 

 in connection with the \arious species — should be a 

 great determining factor. Possibl\- also most collectors 

 will like to have a good series of such as keep their 

 colours well, and .so make a good show in the cabinet. 



A collection of Dragonflies admits of ver)- easy 

 labelling, and one of the comparatively large spaces 

 on each side of the abdomen below the hind-wings 

 seems marked out for the position of a neat label 

 bearing particulars of local it}' and date of ca[Jture ; 

 but this should onl\- supplement a fuller account in 

 the collector's note-book in connection with all the less 

 common species or more striking varieties.
