PREFACE. Vii 



following work. Having thus prepared .the way, 

 he next points out those characters, which appear 

 to him to distinguish the genus in question; and 

 assigns his reasons for dividing into two genera 

 those insects which by Linneus were considered as 

 genuine Apes, subjoining their Essential, Artifi- 

 cial, and Natural Characters. With respect to the 

 last, though he varies from the practice, yet he 

 conforms to the precept of Linneus (a); and he 

 thinks that Fabricius has rendered no small service 

 to the science of entomology by the introduction 

 of them. Then succeed, what appear to him, after 

 combining anatomy with habit, economy, and affi- 

 nities, the natural families into which these two 

 genera may properly be divided. 



And here, to trace the footsteps, and elucidate 

 the system of nature, and nature's God, has invari- 

 ably been his aim; to discover the wonderful 

 works, and adore the wisdom of his Creator, his 

 highest pleasure; and to point out his meaning, 

 and see things where he has placed them, his single 

 desire. Unattached to hypothesis, he has made 

 haste to give up errors as soon as he has detected 

 them, and he has taken every step within his power 

 to arrive at the truth. With respect to this part of 

 his undertaking, he has not been satisfied with dis- 



(a) Linneus, in his Methodus demonstrandi lapides, vecretali^ 

 da aut animalia, under the head Genus, includes as a necessary- 

 adjunct. " Character Naturalis omnes notas churacleristicas 

 possibiles exhibens."
