APPENDIX. 
Hessian Fly. Cecidomyia destructor, Say. 
(Continued from page 25.) 
During the winter further communication has been forwarded 
regarding Hessian Fly, showing its presence to be more widely 
distributed than was at first supposed; also regarding observation of 
the puparia or “ flax-seeds ” in the siftings beneath the machines ; and 
other information bearing on spread, or prevention of spread, of the 
attack, of which I give some of the main points, as follows :— 
“ Flax-seeds ” or Puparia."^' 
On January 17th of the present year (1887) some specimens of 
Hessian Fly “flax-seeds” were forwarded to me by Mr. D. Taylor, 
jun., of Daleally Farm, Errol, N.B., with the information that he was 
then finding a good many of them between the blade and stalk on 
Wheat straw. In reply to my enquiry as to where they were found, 
Mr. Taylor wrote, on January 22nd :—“I have found them in the stack 
before being threshed; amongst these the sample sent to you. I have 
found them on the straw after being threshed; it was on this that I 
first found them; and since reading your pamphlet I have found them 
to the number of seven in a small handful of Mustard and other such 
small seeds, which fall through the sieve, after going over the mill- 
fanners, and also two sets of dressing-fanners with which our 
threshing machine is furnished. The two former were Wheat, the 
latter barley. I at first thought that the pest was only to be found on 
Wheat grown on light land after Potatoes; but after further observa¬ 
tion I find it on Barley grown both on fine light black soil and heavy 
clay (for we are situated in the centre of the Carse of Gowrie).” 
The number of farms in the district on which “ flax-seeds” have 
been reported as observed up to the 24th of February was nine,—eight 
in the parish in which Daleally is situated, and one about six miles 
more to the west on the border of Kinfauns parish. The area of the 
* As before mentioned, the chrysalis-cases or puparia of the Hessian Fly are 
called “flax-seeds” from the great resemblance which they bear to this kind of 
seed both in shape and colour.
