Preface. 



Six years have elapsed since the publication of my "Syno- 

 nymic Catalogue of Diurnal Lepidoptera"; and I have the 

 satisfaction to believe that it has been found useful to Ento- 

 mologists. The present Supplement is brought down to June, 

 1877, and includes all new species described since 1871; all 

 fresh figures or descriptions of importance; and all omissions 

 which I have been able to discover. 



The new species are arranged in alphabetical order, 

 no other arrangement being suitable for a Supplement, and a 

 'full Index has been added. The Supplement is paged, and 

 the new species are numbered consecutively with the original 

 work, for convenience of binding and reference. 



I have not seen reason to modify my views on nomen- 

 clature, further than that I now consider the 10 th edition of 

 pLinne's "Systema Naturae", (1758) and not the 12 th , (1767) as 

 :ne ouly tenable starting point. This is carried out in the 

 Supplement, but does not affect the synonymy to any appre- 

 ciable extent. 



Very numerous rearrangements, and corrections of syno- 

 lymy (often contradictory) have lately been published, or sug- 

 ;estecl to me privately. The former could not be introduced 

 a a Supplement, and I have only attempted to give a few of 

 he latter. The generic synonymy has been left nearly unai- 

 ded from that of the original Catalogue and its Appendix; 

 ence but few of the new genera proposed since its publication 

 'ill be fouud in this Supplement. 



Should circomstances permit, I hope to be able at some 

 iture time to issue a general Catologue of Moths, and also 

 compendium of the systematic bibliography of the Order 

 epidoptera down to the commencement of the Zoological
