190 My. A. KE. Wegman on New and Unrecorded Species 
Yoshino, the majority of the captures there being made 
at light, whilst most of the captures at Hakodate were 
taken at the lighthouse of Tobetsu in the vicinity of 
that town. 
The total number of species enumerated in this paper 
is 427, of which 117 are, as far as I am aware, described 
for the first time as new species, or varieties. There are 
also 179 species which apparently have not hitherto been 
recorded by any author as occurring in Japan, thus 
making a total of 296 species, or over two-thirds of the 
total number of species mentioned in this paper, which 
have been added to the Japanese fauna as a result of 
eleven years’ continuous work in the before-mentioned 
localities. One hundred and eight species which have 
been recorded as Japanese by various authors since the 
publication of the late Mr. J. H. Leech’s catalogue of 
Lepidoptera Heterocera from China, Japan and Corea, 
have also been included for the purpose of bringing his 
catalogue up to date as far as is possible, and twenty- 
three species have been mentioned on account of im- 
portant changes in synonymy. The present record of 
427 species therefore makes an interesting addition to 
the known Japanese fauna, but is by no means final, 
as there are many parts of Japan which have hitherto 
entirely escaped the attention of the lepidopterist, notably 
in the high and inaccessible mountain ranges of the 
province of Hida, where probably many new species will 
be found. ; 
As this paper is likely to be of more special interest for 
Japanese lepidopterists than for others, it may be well 
to note here that Leech’s catalogue was published, at 
intervals, in the Transactions of this Society for the years 
1898 to 1901. He also published a separate paper, which 
deals with Japanese Geometridae only, in the Annals and 
Magazine of Natural History, Series 6, volumes xix and 
xx, 1897. These catalogues form, I believe, the most 
complete record of Japanese species hitherto published, 
and have been taken by me as the standard authority for 
the occurrence of species in Japan. Details of his various 
papers are given in a note appended below.*
