Not one, even of the many books made in these days, is likely to be thought superfluous by its author. And in spite of - to a great extent indeed because of - the thousand and more original works on Insects now published yearly, it seems that the student has need of a small inexpensive, English book, sketching in outline the whole subject of entomology.
Such a volume as this is necessarily for the most part a compilation. To save space, the names of authorities are not mentioned in the text; but reference figures in heavy type call attention to the bibliography at the end of the book, where a list of works consulted by the author, or likely to be of special use to the student, will be found. Particular acknowledgment, however, is due to Professors Miall and Denny, whose admirable monograph on the Cockroach has been largely used in the opening chapter; to Professor A. S. Packard, whose recent Text-book has been invaluable both as a store of facts and a guide to the literature; and to Dr D. Sharp, whose contribution to the "Cambridge Natural History," has been especially useful in preparing the systematic part of this book.
