PREFACE. 
The tliird part of this Work is devoted to illustrations of types of Japanese 
and Chinese Moths in the British Museum, and therefore may be regarded as 
a continuation of Part II. It perhaps exhibits even to a greater extent the 
strongly marked European character of a great portion of this fauna, as 
remarked upon already in the preceding part. 
Again, the greater part of the species represented are from the Collection 
made at Yokohama by Mr. E. M. Jonas, and that formed by Mr. H. Whitely 
at Hakodate. 
The Chinese species are, almost without exception, nearly allied to 
Japanese forms ; several species, moreover, are common to both localities. 
The descriptions of the third part, like those of the preceding, have been 
prepared by Mr. A, G. Butler, E.L.S., one of the Senior Assistants in the 
Department of Zoology.
