September 1894. A very rare insect, of which Canon Fowler in 
his work on the British Coleoptera says ‘a single specimen in 
Dr. Power’s collection taken in the Orkneys by Mr. Syme. Mr. 
Bold in his catalogue records a specimen from Long Benton, 
Northumberland, but I have not seen the insect, nor do 
I know of any person who has verified it.’ (From whatever 
locality, an Agabus belonging to this species is certainly in
