Confined to the warm area south of the Biwa Lake ; 

 abundant and constant in form and colour from Kago- 

 shima to Kioto, a distance of 400 miles ; and occurs 

 also in Tsushima and in the south of Korea.

Carabus Albrechti, Morawitz. 



Morawitz, Bull. Acad. St. Petersb., 1863, p. 321. Syn.

Spread over all the islands, a space of 1300 miles. 



Mr. Lewis obtained a handsome variety of this species, 

 one male at Suyama (base of Fujisan), and one female 

 at Sawara, the whole upper surface of which is of a 

 golden-coppery colour (the epipleurse and prothoracic 

 episternum also metallic), and the strise conspicuously 

 crenated. The inner edge of the male fore tibiae is 

 distinctly angulated, as in C. maiyasanus, not obtusely 

 prominent, as in the typical C. Albrechti.
