The subject of Vol. VI. of the ' Catalogue of Moths ' is the 

 classification of the Cumdliance^ the third of the fifteen subfamilies 

 into wliich the Hoctuidce are divided, 692 species belonging to 111 

 genera being described in it. The subfamily is characterised by 

 its trifid neuration of the hind wing combined with spineless tibia? 

 and smooth eyes surrounded by eye-lashes of bristle-like hairs, and 

 forms a group of genera very closely related to the Acronyctince, 

 the lowest of the subfamilies of the Noctuidce Trifinoi. 



Sir George Hampson has again to thank all those who have 

 helped him with the earlier Volumes of the Catalogue, for the loan 

 of specimens, and assistance with the present Volume, especially 

 Herr E,. Piingeler of Aachen and Prof. J. B. Smith of New Bruns- 

 wick, the latter having not only presented to the British Museum 

 numerous species of iSfearctic Noctuidce hitherto unrepresented in 

 the Collectioio, but also given much useful criticism and advice 

 daring his recent visit to London. In addition he has to thank 

 Dr. Fletcher of Ottawa and Mr. H. V. Hudson of Wellington, New 

 Zealand, for the gift of several species new to the Collection. 

 Plate CVIII. will appear with Vol. VII. of the Catalogue.
