Bering Island, July- August, 1897 (Dr, Stejneger, Mr. Barrett-Hamilton); Copper 

 Island, August, 1897 (Mr. Barrett- Hamilton). 



This species belongs to the subgenus ArcMlithobius and seems to have not very 

 distant relatives among several species described from Siberia by Stuxberg. This 

 larger suite of specimens shows considirable variation in color, some individuals being 

 quite deep purplish red, while others are rather light brownish. Females of both 

 colors were examined and the shape of the genital forceps seemed to be identical.
