PREFACE. 
YU 
thanks the assistance rendered me by Mr. Oliver E. Janson,F.E.S., 
of Perth Road,London,N.,in identification or comparison of speci¬ 
mens, where I have not the opportunity myself of ascertaining 
these points with absolute certainty. To my sister also, Miss 
Georgiana E. Ormerod, F.E.S., I am always indebted for all the 
aid which constant colleagueship and no small amount of ento¬ 
mological knowledge can give. 
The figures at pp. 27, 28 and 184, are given by permission of 
Messrs. Blackie & Son, Glasgow. Those at pp. 74, 77 and 78, 
by permission of Messrs. W. H. Allen & Co., London. Those at 
pp. 11, 118 and 122, from electros of which the use is permitted 
me for my Annual Reports, by the proprietors of the 4 Gardeners’ 
Chronicle.’ Other figures which are copied, or in part taken 
from various entomological sources, are in almost every instance 
acknowledged accompanying, and the remainder, about 17 in 
number, have been drawn from life in some instances by myself, 
but for the most part by Mr. H. Knight, artist to Messrs. West, 
Newman & Co., London. 
During the past season of 1890, in consequence of the heavy 
work requisite for the preparation of the 2nd Edition of my 
Manual, and the great injury to my health from the long continued 
over-pressure, I was not able to devote the time that I much 
wished to do to tracing out the full history of various attacks. 
But in the coming season, should moderate health be continued, 
and I am still favoured with the kind co-operation of my corres¬ 
pondents, I shall hope to give especial attention to investigation, 
and to be able as before in due season to submit to them again 
another Report.
