EXPLANATION OF PLATES 



Figures on the following plates, whicli are not new, are credited to tlm author 

 from whom they are taken, but such figures are not always copies ; they are some- 

 times reduced in size and the shading is often modified ; occasionally details are 

 changed to make the figure more representative of the species which it illustrates. 

 Where the magnification of the original figure was not given, it has been esti- 

 mated as nearly as possible from the data available, but a question-mark indicates 

 the uncertainty.
