PREFACE. 
Museum, we are much indebted, not only for a ready access 
to his Collection, but also for permission to refer to his valuable 
Entomological Library. 
To John Curtis, Esq., we are also greatly indebted for per- 
mission to make drawings from any of his rare and beautiful 
specimens we might require, and occasionally to use his most 
elegant work on the Genera of Insects found in Great Britain 
and Ireland. . 
We have sincerely to thank Messrs. Bentley and Chant for 
the loan of many very fine specimens of the British Lepido- 
ptera from their valuable Cabinets ; and our acknowledgements 
are also due to Edward Newman, Esq., for the use of some of 
the very rare British species.
