PEEFACE. 



The last printed Catalogue of the Library of the Entomo- 

 logical Society of London was published in 1861, and was 

 bound up with Vol. 5 of the Second Series of the Transac- 

 tions. It extended to fifty-two pages. A comparison of it 

 with the present volume will shew the great additions that 

 have been made since that date, and especially as regards 

 " separata/' the majority of which have been presented by the 

 Fellows of the Society. 



This Catalogue indicates the present extent of the 

 Library; it also shews in what points it is deficient. It is 

 earnestly desired that those Fellows who have the oppor- 

 tunity will endeavour to supply some of the deficiencies, and 

 thus render it necessary to publish a separate Appendix at no 

 distant date.
