tables, and as much information as can be gathered as to 
distribution and localities. I have avoided synonymy as 
much as possible, but have endeavoured always to refer to 
Messrs. Douglas and Scott’s ‘ British Hemiptera” when 
the names I adopt differ from those employed by them; and 
where I use the expression “nec D. & 8.,” I mean that 
the species here described is not the species described under 
that name in their work. Many of these changes of 
nomenclature have been made by the authors of ‘The 
British Hemiptera” themselves in the pages of the 
Entomologist’s Monthly Magazine. In collecting localities 
T have had much assistance from Major Blathwayt, Messrs. 
Billups, Blatch, H. A. Butler, G. H. Carpenter, Champion, 
Dale, Edwards, Dr. J. W. Ellis, Rev. Canon Fowler, Rev. 
W.F. Johnson, Rev. T. A. Marshall, Mr. A. Piffard, and 
Dr. F. Buchanan White, as well as from the following local 
lists: Hastings and St. Leonards and its vicinity ; Lincoln- 
shire, J. H. Mason; Norfolk, J. Edwards; Devon, E. Parfitt ; 
Reigate, J. Linnell. In nomenclature and arrangement I 
have followed Dr. Puton’s “ Catalogue des Hémiptéres de 
la faune paléarctique,” 38"° Edit. : Caen, 1886; but I have 
diverged from it in a few cases where I have found it 
convenient to do so. 
There are probably many new species yet to be added to 
our list, as some parts cf the country have scarcely been 
worked at all. I have obtained very few Welsh localities, 
and the West of England and Scotland, as well as most of 
Treland, have had very little attention from Hemipterists. 
It is hoped that the present volume will be useful to the 
few workers we have in this order, and may induce others 
to take it up as a study.
