flax-seed-like pupa were forwarded to me by Mr. G. E. 
Palmer from his barley fields near Hertford, and shortly 
after the attack was reported as found on other neigh¬ 
bouring farms. On August 10th some small amount 
was found at Stubbers, near Romford, Essex, in wheat; 
on August 28th the same attack, with pupae now advanced 
to the striated condition (that is, with lines running 
lengthwise along them), was found at Ware ; and on 
September 1st and 2nd respectively similar attack was 
reported (with specimens accompanying) from barley 
near Inverness, and also from barley near Crieff, Perth¬ 
shire. In all cases the nature of the attack was identified 
by sample specimens forwarded to me. Reports were 
also sent me of similarly injured straw being observed 
in various parts of Scotland, and that “the insect had 
been observed in various counties widely apart.” 
On September 22nd Mr. G. E. Palmer reported that 
the pupae of the Hessian Fly had been found at three 
farms near Hertford, two farms near Hitchin, one near 
Ware, and one near Luton, Bedfordshire. These 
localities include Mr. Palmer’s farm and that at Ware 
previously mentioned. The observations were taken by 
Mr. Palmer and Mr. H. Dorrington, residents near 
Hertford, perfectly qualified to identify the attack. 
Amount of injury caused by Hessian Ply attack. 
It is unnecessary here to enter on the losses liable to 
be caused by this attack, of which details will be found 
in the works referred to in table appended. They may 
transmission is thoroughly disproved will find the subject entered on at 
length in a paper by Dr. Hagen, entitled, “ The Hessian Fly not imported 
from Europe,” ‘Canadian Entomologist,’ October, 1880. The dates, 
with names of ports of embarkation and those of arrival in America, are 
there given both of the Hessian and German troops; and (to give just 
one note of the various movements specified) it will appear plain that 
where troops left Hesse in February, Spithead in May, and arrived in 
Sandy Hook in July, or up to August 12th, that the “flax-seeds” could 
not by possibility be thus conveyed. If pupas had been in the straw (if 
straw was conveyed) they would have developed long before the middle 
of summer, if they were in a state to develop at all. Full details will be 
found in the paper referred to.
