PREP ACH, .LO.,..VOL.. V. 
In issuing the concluding Volume of this work, I feel that acknowledge- 
ment is due to the many supporters who have helped to make it a 
success, and to the many friends who have so kindly assisted me with 
information as to habits and localities, or by the loan of specimens ; 
besides those whom I have mentioned (Vol. I. Preface, Pp. Vic), Dam 
especially indebted to Mr, S. Stevens, Mr. H. Moncreaff, Mr. W. F. H. 
Blandford and Dr. A. Chapman, and also to Mrs. Power for kindly 
placing Dr. Power’s collection at my disposal.

divisions and families, and I have therefore abandoned the idea of 
dealing further with the subject, especially as I see no reason for 
altering the general classification in the present state of our know- 
ledge. 
As I before said, in a work like the present, in which go many details 
have to be examined and verified, and many thousand references to 
localities collected and tabulated, it is impossible to avoid some errors 
and inaccuracies ; from the few, however, that have been brought to my 
notice, I am induced to hope that they are far less than might have 
been expected ; I may perhaps say, in this connection, that the charac- 
ters assigned to the divisions, families, genera, etc., are such as will 
apply to them universally, or at all events as far as the European fauna 
is concerned, except in a few cases in which it is especially mentioned 
that they apply to British species only, and in one or two instances in 
which I have, in error, adopted characters which I have afterwards found 
not to be universal (e.g. Anthicide, Vol. V. pp. 8 and 83, on which a
