by their authors, a helpful kindness which I only regret I am not 
able to reciprocate more fully. 
In the identifications, or confirmation of my own identifi¬ 
cations, of some of the insects mentioned in this Eeport which 
were previously little known here, or had not come under my 
notice previously, I have availed myself of the skilled aid of Mr. 
Oliver E. Janson, F.E.S., Perth Eoad, London, N., who has 
aided me greatly in my researches. 
At home as ever, I am always assisted by the colleagueship of 
my sister, Miss G. E. Ormerod, and being able to benefit by the 
assistance of my lady secretary and amanuensis, Mrs. Hartwell, 
aids me much also. 
The figures given in this Eeport are from the following 
sources. I beg to acknowledge with thanks permission from 
Messrs. Blackie, Glasgow, to use electros of the figures given at 
pp. 14, 16, 19, 22, and 101. 
From the ‘Gardeners’ Chronicle’ series, those at pp. 76, 77, 
and 84. The figures at pp. 56, 57, and 79, are from Newman’s 
‘British Moths,’ with the exception of the Wingless Moth 
(walking) and the Looper Caterpillar respectively in the first 
two figures, which are from the ‘ Praktische Insekten Kunde ’ of 
Dr. E. L. Taschenberg, and the twig with moth-eggs in the 
third, which was drawn for this Eeport. 
Fig. p. 81 is from ‘Insects Injurious to Fruit,’ by Prof. W. 
Saunders, Canada. 
The remaining twenty-four wood-engravings have been almost 
entirely drawn from life for these Eeports, in some portion by 
myself, but usually by Mr. Horace Knight, artist to Messrs. 
West, Newman & Co., Hatton Garden. Of these, the figures 
(eight in all) of the Clilorops -infested Barley-plant; and the 
Barley-stem, with its saddles; the Wheat-bulb Fly; the two 
figures of the White Woolly Scale, including the Scale-infested 
spray, from a photo, by Mr. T. P. Newman; the little Apple- 
twigs; and the Turnip “Mud-beetle,” are new illustrations drawn 
for the present Eeport. 
For the large plate of Tylenchus devastatrix I am indebted to 
the courtesy of Dr. J. Eitzema Bos in allowing me to have copies 
made of some of his own excellent drawings from life, and also 
revising the plate himself before publication.
