CORN SAWFLY.

would probably be no way injured. If it could be completely buried 
down and left there this would answer; but I believe the most sure 
plan is after harrowing, &c., to collect the stubble in heaps and burn it. 
The first signs of the coming of the attack of the Corn Sawfly 
which proved so noticeable last year were reported to me by Mr. 
Thomas P. Brand, of Brook Hall, Foxearth, Long Melford, on the 
28th of June; this is worth remarking, for it is very seldom indeed 
that it happens that in crop-attacks of this kind we have information 
of the appearance of the insect, be it fly or otherwise, which will give 
rise to the mischief, before the crop has shown that the havoc has 
been established. 
Mr. Brand wrote me on June 28th :— 
“ I have sent you two flies which I caught off my Wheat last 
evening, and saw a great quantity more of them.” 
Of these specimens one was still alive, and was excellently 
characteristic of the appearance of this kind of Corn Sawfly, as 
described at length further on. 
On the 20th of July Mr. Whitehead informed me that he had a 
lot of straw (Barley) sent from Huntingdon, with Cephus pygmaus 
maggots in every stem. 
July 26th. Mr. W. Bance wrote me from Taplow, Maidenhead, 
that he had six acres of spring Wheat, which had a very bad 
appearance, and on examination he found it aftected by a grub in the 
stem close down to the root,—specimens accompanying showed this to 
be the Corn Sawfly maggot. 
On the 28th of July Mr. William Hall forwarded me a parcel of 
Wheat roots and stems, containing a grub close to the ground, from 
Redbourne, Kirton Lindsey (Lincolnshire), with the observation that 
he had been much struck by a quantity of his AVheat appearing as if 
it was what is called storm-broken, and on examination he found in 
all cases that there was a grub, either close to the ground or a little 
way up the stem. 
The samples forwarded proved to be remarkably characteristic 
specimens of Corn Sawfly attack ; the Sawfly maggot was down quite 
at the bottom within the stem, and the crisp, clean breaking oft ol the 
stem at the ring which the maggot had bitten within was very noticeable. 
On the 1st of Aug. Mr. W. Hall further mentioned that the Sawfly 
attack had quite damaged the yield of the Wheat in that parish 
(Kirton Lindsey) from a sack to a quarter of an acre. 
On July 30th Messrs. Sutton and Son, of Reading, consulted me 
regarding attack to a large quantity of Wheat on a faim in the 
neighbourhood of Reading, which on examination of specimens pioved 
also to be injured by Ceplius pygmaus ; and on the same day Messrs. 
Oakshott and Millard likewise desired an opinion on “ stems of Wheat
