We are indebted to Mr. J, A. Brewer for a specimen from the 
collection of the late Mr. Heysham, of Carlisle, which there is good reason 
to believe was taken by him in that locality. Mr. J. B. Hodgkinson, 
of Preston, writes in answer to our enquiry, — " Tliere can be no doubt 
" that Mr. Heysham's Hydrometra is British. Mr. Heysham had no 
" idea of anything foreign, and rarely, if ever, bought any insects but 
" such as were taken near Carlisle. He was a reserved, exclusive, and 
" most laborious naturalist, and no one helped him in any order except 
" Lepidoptera^ 
The species is found in Prance, Italy, Germany, and Eussia: 
therefore it is likely to occur in Britain ; but although the name was 
introduced into the British List by Stephens and Curtis, the insect to 
which it was applied was II. iJioracica, Schum., as Curtis' s description 
(B. E. xii., 553, 3) shows.
