THE HESSIAN FLY.

not think that serious harm has been done. It is worthy of note, 
however, that the effect on the Wheat in producing stunted ears is 
more marked than in last year.” 
Mr. James Walker, writing on July 24th from Ashwell, Baldock, 
Herts, forwarded me specimens of Hessian Fly-infested Barley-stems, 
with the mention that:—“We have about fifty acres of Barley that 
EO 
Attacked Barley-stems. 1, elbowed down; 2, showing “flax-seeds.” 
lias about every fifth stem broken down with it at the second joint 
from the root, and I can find it more or less in most of the Barleys 
that I have examined, also a few in the Wheat.” 
On July 30th, Mr. J. Walker, reporting further, remarked :—“I am 
very sorry that we have such a severe attack of the Hessian Fly, but 
it does not seem to do much damage on any of the other crops, except 
the one fifty-acre field of Barley where I first discovered it, and it will 
destroy several bushels per acre on it.” 
On July 30tli, specimens of Wheat-straw infested by Hessian Fly 
were forwarded me by Mr. K. Rix from Somerleyton, near Lowestoft. 
In this case I did not find more than one chrysalis present on each straw, 
and Mr. Bix mentioned that although he found “Fly” present in 
several pieces of Wheat, yet it was not in great number. 
Very similar specimens, that is to say, Wheat-straw with very little 
infestation, not more than one or two specimens on each stem, were 
sent me on August 8tli from Salisbury Hall, Ridge Hill, Barnet, by 
Mr. R. Makins, and in this case also it was reported as not having done 
much injury to the Wheat,
