The injury to barley was most noticeable in a field of 33 acres,

quent investigation, up to the present date of writing, the pupae 
of the Hessian Fly have been found by Mr. G. Palmer or Mr. 
H. Dorrington, of High Mead, Hertford (both of whom I know 
to be thoroughly able to identify the attack), at the following 
localities : — three farms near Hertford ; one near Ware ; two near 
Hitchin ; and one near Luton, Beds. 1 have myself been able 
to identify similar attacks from a farm near Romford, Essex, 
also specimens have been sent to me from a locality near Inver- 
ness, and near Crieff, Perthshire, together with a communication 
from a member of the staff of the ' North British Agriculturist,'
