THE CABINET ARRANGEMENT OF SPECIMENS 137 



obtained later on will not compel you to be continually moving and 

 rearranging the drawers. 



Probably the number of blank spaces will at first suggest an 

 almost hopeless task, but a few years of careful searching and 

 rearing will give you heart to continue your interesting work. 



Arrange all the insects in perpendicular rows. Put the names 

 of each section, tribe, family, and genus at the head of their 

 respective divisions, and the names of the species below each insect 

 or series of insects. The opposite plan, in which the circles 

 represent the insects themselves, will make this clear. 



Three or four specimens of each species are generalty sufficient, 

 except where variations in colouring are to be exhibited. Wherever 

 differences exist in the form or markings of the sexes, both should 

 appear ; and one specimen of each species should be pinned so as 

 to exhibit the imder side. 



Finally, each drawer or box should have a neat label outside 

 giving the name or names of the divisions of insects that are 

 represented within. This will enable you to find anything you 

 may require without the necessity of opening drawer after drawer 

 or box after box.
