reared under Mr. Inchbald’s own care from British puparia) were 
kindly distributed by liim, so as to be in the bands of those especially 
interested in the matter, amongst whom were Prof. Westwood, Life- 
President of the Eoyal Entomological Society; Mr. B. H. Meade, our 
well-known eminent Dipterist, whose excellent description of both 
male and female has been given at pp. 15-16 ; Mr. Whitehead, of 
Barming House, near Maidstone (Agricultural Adviser to the Depart¬ 
ment of Agriculture); myself, and some others. There is therefore 
now no want of well-authenticated specimens of this new corn-pest, so 
placed as to be available for service. 
On July 19th Mr. Inclibald wrote :—“ The last I bred was a female 
on July 13th. Altogether I have reared twenty-seven specimens of 
C, destructor .” 
May 20th, Mr. D. Taylor, jun., of Daleally Farm, Errol, N.B., to 
whom we are all indebted for his long and carefully conducted observa¬ 
tions on Hessian Fly, and matters connected with it, reported to 
me, on May 20tli, that he had bred the perfect insect from his “ flax¬ 
seeds.” 
On July 20th Mr. C. Whitehead wrote me, from Barming House, 
near Maidstone :—“ I have found to-day a Hessian Fly, hatched from 
last year’s puparia, in the bottle in which they have been since 
Christmas. This proves that they will remain a long while in 
pupal form, and are more dangerous thereby. I put moisture in 
the bottle about a fortnight or three weeks ago.” 
The above notes are of serviceable interest, as showing for one 
thing the effect of moisture in bringing about development of the fly, 
and, for another, how long development and the appearance of the fly 
from the puparium or “ flax-seed ” may be postponed, as these “ flax¬ 
seeds ” were collected from crops gathered in the preceding autumn. 
The protraction of time of development in non-natural circumstances 
is of some importance practically, and attention has been drawn to 
the point by Dr. Lindeman in his work on the Hessian Fly in 
Kussia. —Ed. 
First Appearance of Hessian Fly Attack on Barley in 1887 
in England and Scotland. 
The three following observations refer to the first records given of appear¬ 
ance of Hessian Fly in its maggot and chrysalis stage on the growing crops 
in 1887. The first observation was reported on July 7th, the second on 
July 11th, and the third on July 12tli; the first of these observations being 
Scottish, the two others English. 
On July 7th Mr. Pattullo wrote as follows from Eassie Farm, 
Meigle, N.B.:—“I have sent to-day a box with stems of Barley
