INSTRUMENTS, ETC., REQUIRED. 37 



ton lens will be required for the very minute species. 

 A square bung to stick the pins into is very handy, and 

 a pair of insect pliers almost indispensable. 



Insects that have become dry, or old specimens, may 

 be relaxed in a jar of damp sand ; they can then be s.et by 

 gumming them on card, and as soon as the gum is dry, 

 damping one side only, and putting the limbs out ; 

 afterwards serving the other side in the same way. If 

 required, the body or any of the limbs can be kept in 

 position by small card-braces with pins through them. 



" Benzine " is most useful in cleaning old beetles, 

 restoring their colours, and removing grease; which 

 latter is very apt to appear in imperfectly dried speci- 

 mens, especially if they have been left for too long a 

 time in laurel. 



The collection should be arranged in corked store 

 boxes (containing a little camphor to keep away mites), 

 until sufficient material is acquired to render the pur- 

 chase of a cabinet necessary; and a catalogue of our 

 British species, printed on one side for labelling, can be 

 obtained of Mr. Waterhouse, at the British Museum.
