DESCEIPTION 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 : X .
