IN the year 1906 the Trustees of the British Museum pubhshed a volume
entitled " Illustrations of British Blood-sucking Flies," consisting of coloured
plates, reproduced from enlarged drawings made by Mr. A. J. Engel Terzi,
with accompanying notes by the late Major E. E. Austen.
The utility of this volume was proved by the fact that the edition was
exhausted within a few years. By 1921 continued demands for the work
and the extent to which fresh data relative to the subject of the book had
been accumulated, made the preparation of a second edition desirable. This was
arranged for, and drawings for twelve new coloured plates were prepared by
Mr. Terzi and completed in 1923. Unfortunately Major Austen's duties as
Deputy-Keeper and subsequently as Keeper of the Department of Entomology
prevented him from completing the text to accompany these plates ; it was hoped
that he might be able to do this after his retirement, but again other work
prevented him.
The text of the volume now issued has been compiled by Dr. F W.
Edwards, Mr. H. Oldroyd and Dr. J. .Smart. The whole-plate illustrations
already prepared have been supplemented by a large number of text-figures
in order to illustrate more fully the distinctions between the various species ;
in addition, keys have been included for the determination of all the British
species of the blood-sucking groups. It is believed that these features will
increase the value of the work to students.
The manuscript left by the late Major Austen dealt only with the
Tabanidae. It has been freely drawn upon by Mr. Oldroyd in his account of
the species of this family, but has at the same time been revised and re-written
in accordance with recent discoveries.
As in the earlier work, the aim in this edition has been to provide in the simplest
manner information of interest to non-specialists ; technical terms are so far
as possible avoided, and no attempt has been made to give full descriptions of
the insects, while in the Nematocera, the males (which do not suck blood)
have been omitted from consideration. A brief summary has, however, been
included of the known facts regarding the habits, life-history, and distribution
in Britain of every blood-sucking fly known to occur within these islands.
