3 8 - Thecla arata, Brem, (Pi. 4， fig. i〇.） 



Localities ― Nikko, Fujisan, Gifu, Yezo. 

 Time of appearance ― May to July. 



This is a very beautiful mountain insect. Both sexes are nearly alike. 



39- Thecla attilia, Brem. (Pi. 4， fig. n) 



Locality ― Yokohama. 



Time of appearance ~ May to July. 



This is the most abundant Thecla about Yokohama. The markings on both the upper and under 

 sides vary considerably. In many specimens there is no trace of the greyish white spots on the upper siae 

 of the hind wing, and the markings on the under side differ considerably. 



40. Thecla enthea, Janson. (Pi. 4， fig- 12.) 



Time of appearance ― July. 



This is not uncommon at Nikko, and is abundant at Asama-yaina. 



41- Thecla w-album, Knoch. (Pi. 4， fig. 14.) 



Styymon fenton" But. 

 Locality ― Yezo. 



This Thecla is common in Yezo, and varies considerably in size. Mr. Butler lias unfortunately obtained 

 a rather large specimen, which he has named Strymon fentoni. It is figured in the "Aid," Part. 14, pi. 115. 

 I have several female specimens of T. w-album which correspond with the figure, and find that the white 

 line on the under side is very variable. 



42. Thecla pruni, Linn. (Pi. 4， fig. ふ） 



I have a single example, taken by my collector in Yezo.
