This species was first noticed in this country about the 

 1875-6, when two specimens were taken at light at night at 

 Trinity College, Cambridge, by Mr. F. J. H. Jenkinson. 

 More recently it has been found by Mr. N. M. Eichardson 

 near Weymouth, Dorset, about silver fir, flying at dusk near 

 the tops of the trees, whence it was difficult to induce them 

 to descend. Elsewhere it has been found in North Devon, 

 Hants, Essex, and Norfolk. So far as I know these six 

 counties comprise its whole range, as yet, in the British Isles. 

 Abroad it is found almost all over Central Europe and in 

 North-west Eussia.
