Var. i. Not. Davisii. Eni. Mag. {Waterhouse) v. i. 205. — Deep black: thorax 



much narrowed behhid ; elytra not very deeply striated, with a pitchy dash 



on each side near the apex. 

 Var. |. Not. Newmanni. Ent. Mag. (Waterhouse) v. i. 205. — Rather long: 



frontal sulci divergent; thorax long and much narrowed behind. 

 The last three varieties were found on Snowdon : other examples both of them 



and of others have occurred at Cambridge, near London, &c. 

 I think it very probable that all may be mere varieties of N. aquaticus.
