Excerpt from Elements of Entomology: An Outline of the Natural History and Classification of British Insects Amongst the numerous works published on Ento mology, it appeared to the author that there was none which gave, in a popular and readable form, an outline of the principal groups into which Insects are usually divided. It was with the object of filling up this gap in our Entomological literature that the present little book was written.

Excerpt from Studies in Entomology: A Practical Work on Insects, Containing Suggestions and Outlines for Nature-Study in School Work A knowledge of this and the succeeding pages of this chapter will add interest to the sketches which are to follow, as well as ex plain many terms which might not otherwise be clear. Especially is it to be desired that the reader understand the anatomy of the grasshopper, as that insect is taken as a type of insect strue ture.

Excerpt from Insects of Economic Importance Outlines of Lectures in Economic Entomology Not all insects of economic importance are included in these outlines. To discuss them all, a book of many times the size of this would be needed. However, the principal pests of our main fruits, vegetables, cereals, farm animals, shade-trees, and of the household are discussed. A brief summary of the life habits of each, so far as they are known, is made, and the latest methods of control are outlined. In addition, a concise discussion of insecticides is given together with formulae and directions for making and applying them. Finally, references are given to the more important sources of information regarding the insects and their control. As far as possible, references are made to bulletins available to the general student and to those publications giving good illustrations of the insects, together with the most approved methods of control. It is neither possible nor desirable to give references to all the literature on any one insect pest but additional references to the later literature as it appears from time to time will be cited during the course.

This text book starts with general entomological issues, surveying the significance of insects, their internal and external structure and how they reproduce, develop and sense their environment. Key features in the success of insects are explored in a phylogenetic interpretation of their evolution. Major themes in insect biology follow: the ecology of ground-dwelling, aquatic and plant-feeding insects, and their social, predatory, parasitic and defensive behaviour. Special consideration is given to insects in medical, veterinary and agricultural science, and to pest management. The traditional order-by-order arrangement of other texts is replaced by a systematic synopsis of each insect order at the end of the appropriate ecological/behavioural chapter. The theoretical framework of cladistics and current evolutionary and behavioural theory underlies the text. Over 200 beautiful drawings of insects, many as seen under natural conditions, will encourage the rewarding study of entomology, whether as a vocation or as a hobby. This book is suitable for students contemplating entomology as a career, and may be used as a principal text for higher education courses in which the study of insects is prominent. These range from mainstream entomology to agricultural science, forestry, zoology and medical and veterinary science.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from The Elements of Insect Anatomy: An Outline for the Use of Students in Entomological Laboratories The course of study outlined in the following pages is de signed to enable students to learn the more general features of the structure of insects. It may serve as an introduction to a more extended study of insect morphology. While the more obvious object of this course is the learn ing of certain facts, a much more important thing to be gained is a training in methods of careful observation. The student is urged, therefore, to do the work with great care. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Entomology in Outline: Compiled for the Use of County Horticultural Commissioners and Fruit-Growers Some simple work, which shall present, in plain, every-day language, information about the insect world, has long been desired by our County Horticultural Commissioners and fruit-growers. As a rule, these men are not scientific entomologists, nor do they need be, but, at the same time. It is necessary that they should know something Of insects and their modes Of living, and be able to distinguish between insect friends and enemies, in order that they may protect the one and destroy the other.

Excerpt from Outlines of Entomology In preparing the following pages, as an introduction to the science of Entomology, the primary object has been to supply a need of the farmer and horticulturist. For while the ravages of noxious insects have an indirect effect upon the prosperity and convenience of every one, it is to the agriculturist more directly that their absence or prevalence brings financial success or failure. It is true that there are already almost innumerable publications, many of them of great value, on the subject of economic entomology, as well as those of more strictly scientific importance, all of which are accessible to any inquirer; but it is undeniable that a lack of some general knowledge of the life histories of insects, and an unfamiliarity with many of the terms used in description, deprive those for whom they are prepared of a large share of the benefit they might derive from them. I do not ignore the fact that this want has been realized by many of our most distinguished entomologists, and that several text-books have been prepared to meet it; but the objective to these is, that the authors have gone into the subject too thoroughly, have dwelt upon points of structure that the business man has neither time nor skill to trace out, have discussed phenomena that are chiefly interesting to the philosopher, and which make the study seem too abstruse. The following pages are an attempt at something more elementary, remembering that there are those who have yet to learn the difference between a beetle and a bug, or between a moth and a butterfly; to whom the transformations of insects offer a puzzle which they cannot solve, and who are completely daunted and discouraged by a half-dozen successive technical terms. This little introduction aims to help the beginner over some of the first difficulties he is liable to encumber in taking up the subject systematically, and the author hopes it will be the means of attracting him to the study of the more exact and comprehensive treatises of Dr. Packard, Prof. Comstock and others.
