My association with Prof. Hering extends over the past seventeen years, and during this period I have visited him at his home on more than forty occasions and received over 300 letters from him. These letters contain much detailed entomological information. They also throw considerable light on Prof. Hering's personality and character and the background against which he worked. The publication of at least part of these letters as a final tribute to Prof. Hering has been in my mind for many years. This original idea has now been somewhat extended by the inclusion of a number ofletters to Dr. H. Buhr, Dr. J. Klimesch, Dr. F. Groschke and G. C. D. Griffiths, all of whom shared Prof. Hering's interest in leaf-miners. Although Dr. Buhr is primarily a botanist, with Hering's encour agement he has taken an active interest in leaf-miners throughout his career and his remarkable collecting becomes apparent from Hering's letters to him. For many years Prof. Hering has written between two and three thousand letters annually. It has obviously been possible to consider here only a very small proportion of these. From many of the longer letters only isolated paragraphs have been included. Use of italics in the letters was not entirely consistent and has been reproduced as used by Prof. Hering. Selection of the letters has been based primarily on their entomolo gical interest but numerous passages have also been included illustra ting in some way Hering's personal qualities.

The original stimulus which started KENNETH SPENCER on a study of the Agro myzid flies was an invitation, which he accepted, to translate from the German the monograph on Leaf Miners by Professor E. M. HERING. From this developed nearly 20 years of collaboration until Professor HERING's death in 1967. Dr. SPENCER has himself described over 600 new species in the family, many of which he collected and reared from known host plants during his extensive travels to all the five main continents. Largely as a result of his work, the number of species known in Britain has increased from 90 in 1945 to 313 today. He is thus uniquely qualified to write this book about the hundred and fifty or so species which are regularly associated with cultivated plants. Much of the taxonomic detail provided here will be of value primarily to specialists; but with the help of a microscope and the botanical host list (Chapter 2) and the numerous illustrations (mostly prepared by ANN SPENCER) those in agri cultural institutes and elsewhere should now be able to identify the majority of species found attacking crops in any part of the world.
