43 



Length of forewing 7 mm. 



Width of forewing 3 mm. 



Length of hindwing 6 mm. 



Habitat : Sapporo, Hokkaido (four female specimens captured by 

 Mr. H. Okamoto on October 11, '14). 



Remark : This is known as the "mountain loving species" in Europe 

 and also in North America, and was recently reported by Navas (I.e.) from 

 Siberia. The Japanese specimens on hand differ somewhat from the Euro- 

 pean form in being slightly larger, and in the color of wings being to a 

 degree lighter ; nevertheless, all are without doubt specifically identical.
