I did not meet with this species in Japan, but there were four 

 males and three females in Fryer's collection. Three of the former 

 and one of the latter are labelled Yesso, 1882. In the same col- 

 lection three small specimens of L. auripes, also from Yesso, were 

 set apart and are the no. 161 of Fryer's Catalogue. These small 

 specimens agree with a series I obtained at Gensan in 1886. The 

 smallest J in this series measures only 40 millim., and the largest <S 

 49 millim. ; the smallest $ 44 millim., and the largest $ 58miUim. ; 

 whereas the measurements of typical examples are, 58 millim. for S , 

 and G8 millim. for $ . 



Common at Gensan, flying among fir-trees in the daytime. 



The primaries of § have no black costal edging as in the <S •

Four males and one female, coll. Fryer. The male from Japan, 

 like the same sex of this species from Ningpo and Kiukiaug, has a 

 round black spot at end of discal cell instead of the usual L or V. 

 The female, on the other baud, has a well-developed V-like mark.

Several examples in coll. Fryer. Ferhaps a little more densely 

 scaled, but otherwise Japanese specimens agree very well with the 

 European type.

Among Japanese and Corean examples of this species there is 

 much variation in the markings of primaries. In typical ^ spe- 

 cimens of P. aurijiua there is a brownish-black spot on the inner 

 margin near anal angle, and such specimens there are in my series 

 from Japan and Gensan ; but others have an additional spot towards 

 the base of the inner margin, and other examples again have a third
