from May to September. Pryer says that it goes only a short 

 distance up 'the mountains, where it is replaced by L. diana Butler. 

 However, I have taken specimens up to an altitude of from 

 300 to 500 meters (1,000 to 1,500 feet) on the mountains of 

 Omine-san and odai-san in Yamato Province, Honshu. In Tosa 

 Province, Shikoku Island, it occurs in May, and I have taken 

 it at Nikko, Honshu, in the same month at an elevation of about 

 500 meters (1,500 feet). 



Fruhstorfer •- describes a distinct race of L. sicelis from 

 Kyushu, which he names vanelia. It is characterized by the 

 absence of the gray- or blue-violet bordering to the eyespots 

 on the underside of the hind wing which is always present in 

 examples from Hondo (Honshu) and which Hewitson and 

 Seitz 23 distinctly figure.

The larva figured (Plate III, fig. 1) was taken on June 3, 

 1902, at Hakodate, Oshima Province, Hokkaido (Yezo), on bam- 

 boo grass, sasa-gusa (? Lophatherum elatum Zoll.). It pupated 

 on June 15, 1902, and a female imago emerged on July 3, 1902. 

 A male and female emerged from similar larvae on June 27 and 

 July 2, 1902.
