AS a general hiftory of the Entomological productions of 

 Great Britain, this Work has been long acknowledged the 

 molt copious hitherto fubmitted to the Public. The firft 

 part, comprifmg no lefs than ten volumes, having already

 the fpace of ten years, were pleafed to fanction it with 

 the bed teltimony of their approbation. The publication

 occaiion of this delay is lufficiently known. The Author

 to this work, and was unwilling to treipafs beyond the li- 

 mits thole engagements prefcribed. — He Hated, notwith-

 cal purfuits : that his attention would be directed to a fci- 

 ence iri'whicja the part indulgence of the public had induced 

 him to believe he might yet be ufeful; and that, mould a 

 number of new and valuable infects occur, they would be 

 certainly added in a fupplemental form to improve the 

 former work. Since that period, the author has been led to 

 , conceive, his endeavours might not prove unacceptable in 



elucidating
