DESCRIPTION OF THE PLATES. 
All the figures are original, and have been drawn direct on the stone by Mr. E. 
Wilson under the personal supervision of the author. In order to save time and 
expense, the forms and varieties have not been fully shaded. Most of the figures have 
been so arranged as to facilitate a comparison of the different male and female forms of 
closely allied species. When the figures are enlarged, an adjoining line indicates the 
natural size. 
N.B. Previously unfigured forms are marked thus: xX.
