I should think myself totally unpardonable, if I finished this address without acknowledging the obligation I am under to several friends, whose assistance in this work claim the utmost return of gratitude; among these, in a most particular manner I must mention Dr. Fothergill, whose readiness to encourage and promote every part of natural history, must endear him to every man who wishes well to so useful and beneficial a branch of knowledge; and it is to the kindness of that gentleman the reader will perceive I am indebted for a great number of figures that form a considerable part of this work; many of which are so very rare, as not to be met with in any other cabinet. {1}ILLUSTRATIONS OF EXOTIC ENTOMOLOGY. ---- PLATE I.
