The subject of Vol. IX. of the ' Catalogue of Moths ' is the third 

 and final part of tlie very large Noctiiid subfamily Acronyctince ; 

 it contains 12b species belonging to 185 genera as compared 

 with 843 species belonging to 9G genera in Vol. VII., and 7^0 

 species belonging to 104 genera in Vol. VIII. 



The comparatively short list of unrecognised species belonging 

 to the subfamily, at the end of tlie Volume, is evidence of the 

 ready help given to Sir George Hanipson by the loan of types and 

 specimens by Entomologists interested in the subject. 



A large proportion of the species included in this list were 

 described by the older authors and the types are lost. 



Plate CXLVIII. will appear with Vol. X. of the Catalogue.
