Royston.” [some Barley-straw was enclosed with chrysalids at the 
third joint.— Ed.] 
Mr. E. Blundell, writing from Birchmoor, Woburn, on Aug. 3rd, 
informed me that he had then only seen three specimens of “ flax¬ 
seed,” but would search more carefully and report if he found them 
or the larva in any number. 
August 5tli. Mr. Herbert Fenning, of Bedford Estate Office, 
Bedford, forwarded me specimens of Wheat infested by Hessian Fly 
from one of His Grace the Duke of Bedford’s farms at Cople, near 
Bedford. In this case the puparia or “ flax-seeds” were mostly at the 
third knot, although some were at the second and fourth. 
August 6th. I received specimens of puparia taken by Mr. F. E. 
Fraser, from some of the Wheat-plots at the Experimental Farm, 
Woburn. One of these “flax-seeds” was placed near the root, 
and the strise running lengthwise along the chrysalis-case were very 
observable. 
August 8th. The following communication was sent from Weldon 
Grange, Corby, Kettering, by Mr. J. Rooke, together with specimens 
of Hessian Fly “ flax-seeds,” some of which were placed at the fourth 
knot of the infested straw:—“I enclose herewith several plants of 
Barley taken to-day from one of my crops, sown February 15tli, and 
growing on gravelly land. I fear they contain pupa-cases of Hessian 
Fly ; they are the first I have seen, and I have not heard of them in 
this neighbourhood. You will observe that the grain does not appear 
to be materially injured.” 
August 8th. Mr. G. Cook, of Flitwick Wood Farm, Ampthill, 
Beds., forwarded specimens of “flax-seeds” on Barley, together with 
specimens of attack of Chlorous, noticed under this head elsewhere. 
August 8th. Mr. G. A. Saunderson, of Hook’s Mill, Guilden 
Morden, near Royston (Cambs. and Herts), forwarded specimens, with 
the note that two of them “ have the pupse close to the root—so close, 
I think, if the stubble was burnt, unless first pulled up, the pupae 
would not necessarily be destroyed. Three specimens of Wheat and 
one of Barley have the stem considerably shortened between the two 
knots, where the pupae are to be found. One straw contains a 
pupa two inches from the knot .... I note the fly is more prevalent 
in Wheat than appeared some time since; but, except in a few cases, 
not so much so as in Barley; in two pieces in this parish close to here 
in the occupation of J, G. Johnson, Esq., it took me, I think, an hour 
to find one. I note also in Wheat, as the ear gets heavier, the 
characteristic bend, as in Barley, is more prevalent. When I began 
to look three weeks since there appeared to be nothing definite to guide 
to the affected straws.” 
August 10th. Mr. L. B. Woodforde forwarded me, from the Park
