CORN SAWFLY.

Mr. Kendrick visited the spot, and forwarded me samples of the 
Barley which were infested, not by Hessian Fly but by Chlorops , and 
badly injured ; and accompanying these he sent a report that he could 
not find any stems bent from insect injury, but found stunted Barley- 
ears, which had not been able to emerge from their sheaths; and on 
referring Mr. Kendrick to the description of Chlorops attack and the 
figure given at the head of this paper, he stated there could be no doubt 
of the identity. 
This account and identification is of importance, as temporarily 
much alarm was raised regarding the supposed Hessian Fly attack ; 
hut, further, it is of interest relatively (as I noticed just above) to the 
low and damp situation of the examined Barley. This was stated to 
be a “good-sized patch in the lowest and apparently rather swampy 
part of the field”; also the ground “ was much overgrown with Persi - 
carias ,” a weed which it is unnecessary to say thrives in moist places. 
If this attack especially affects damp spots, or spots which have 
been wet and then surface-baked, one method of prevention would be 
obvious ; but, as in all the many years in which I have known it this 
attack has never before been serious, I attribute its severity last year 
to the unusual heat and drought, and should not conjecture that a 
recurrence was to be expected.

The presence of Corn Sawfly, like that of Chlorops was much more 
observed than is usually the case in England last year, and the notes
