HESSIAN FLY.

information, on Aug. 1st, that these were from Gidding, Hunts, and 
that he found it there in all his corn crops. And that “ here also in 
Northamptonshire I find it in every crop I have examined.” 
July 18th. Mr. T. P. Brand forwarded a sample of attack from 
Brook Hall, Foxearth, Long Melford, with the note that, if these were 
pup® of Hessian Fly, “ we have got plenty of them on my farm at 
Foxearth, and also on my Shimpling Hall farm, seven miles distant, 
in the county of Suffolk.” The “flax-seed ” in this case were found 
on Wheat, and on Barley also, and the crop was very much damaged. 
It had a root-fallen appearance, and the ears on the affected stems 
were dead and the kernels shrivelled up. 
July 18th. A note was sent me from Beauchamps, Buntingford, 
Herts, by Mr. Bobert Pigg, of a small white maggot with a green spot 
on it near one end, which he found in a piece of Barley. This maggot, 
being situated “ under the flag eating into the stalk,”—on a sample of 
the attack being forwarded to Mr. Palmer,—he returned reply to the 
sender, “lam afraid there is no doubt but that the insect you sent 
me is the larva of the Hessian Fly.” [The green mark often to be 
found along the upper side of the Hessian Fly maggot is caused by 
the green juice of the food it has eaten showing along the food- 
canal.— Ed.] 
On July 19th Mr. F. I. Hunt, who had, as above mentioned, sent 
me specimens of attack to Barley on the 11th of the month, forwarded 
(also from Steeple Morden, Royston) specimens of Hessian Fly attack 
on Wheat. He also mentioned, “I find the Hessian Fly slightly in 
very many pieces of Barley,” 
July 20th. Mr. Palmer forwarded me, from Revell’s Hall, Hert¬ 
ford, the following notes of the advance of the attack :— 
“ Since my return I have made a further examination of our corn, 
and I can see that the damage caused by the Hessian Fly has con¬ 
siderably increased, and is quite as bad, if not worse, than last season; 
this is in the Barley. 
“ I also find a small amount of damage to the Wheat from the 
same cause, but not nearly to so large an extent as to the Barley. I 
have had a specimen of the larva sent me from a farmer at Bunting- 
ford, Herts, who reports that he had noticed a field of Barley was not 
looking well, and, on examining it, found some of the larv® in the 
straw, which he feared was the Hessian Fly. 
“ Mr. Dorrington [of High Mead, near Hertford, a good and com¬ 
petent observer —Ed.] also tells me that he has found pup® in the 
fields near Hitchin, where he discovered it last year. I fear therefore 
that the attack is pretty general this year. 
“ I was paying a short visit to Hampshire last week (near Peters- 
field), and took the opportunity of examining a field of Barley which
