Ketoi, one of the Kuriles, under stones (Mr. Snow). 



The punctures on the third interstice are continued as 

 transverse impressions across the interstice. The thorax 

 differs from that of N. German in being less rounded 

 anteriorly, less sinuated at the posterior constriction (the 

 acute hind angles standing out in consequence much 

 less), and in the lateral margins being broader and much 

 more reflexed.

North Japan ; Kurile Is. 



This species is classed by its author in his brevicollis 

 group, and therefore cannot have anything in common 

 with the N. Snowi above described. I have not seen any 

 insect answering to the description. 



Leistus crassus.

Much more convex and robust than any other species 

 known to me ; black, with a slight brassy or purplish 

 tinge.
