1888.] LEPIDOPTERA OF JAPAN AND COREA. 647 



C. cossus is recorded by Fixseii as taken in Corea by Herz, but 

 this is possibly an error in identification.

A fine series in Prjer's collection. I got specimens in Satsuma 

 in May, Nagasaki in June, Gensan in July, and at Hakone in August. 

 There is some variation in the size of the brownish discal spot ; this 

 is sometimes little more than a dot, and at others quite a round 

 patch. The apical spot is also subject to modification, and in some 

 examples assumes the form of a short stripe. In some specimens 

 there are brownish spots and dots over the whole of the disk.

A female example in coll. Pryer. I took a male at Satsuma in 

 May, and a female at Gensan in July ; this last is remarkable for 

 its large size, as it expands 58 millim. The largest specimen of the 

 same sex I have from either Ningpo or Kiukiang measures only 40 

 millim. in expanse.
