nach der Bestellung gedruckt Neuware - Printed after ordering - 'On the Origin and Metamorphoses of Insects' by Sir John Lubbock explores the diverse life stages and transformations of insects, emphasizing the influence of environmental conditions on larval forms. Lubbock categorizes insects into various orders, highlighting the differences in their developmental processes. He distinguishes between two main types of metamorphoses: heteromorphic, where the larva and adult forms are dissimilar, and homomorphic, where they are more alike. The text delves into the anatomy and life cycles of several insect orders, such as Hymenoptera, Coleoptera, and Diptera, illustrating how larvae adapt to their environments. For instance, larvae that are internal parasites or depend on parental care are typically vermiform, while those that burrow in wood have strong jaws and weaker legs. Lubbock also discusses the evolutionary implications of these changes, suggesting that the current forms of larvae are not original but have evolved due to their specific lifestyles. The work provides a comprehensive overview of insect classification and metamorphosis, offering insights into the evolutionary history and adaptive strategies of these creatures.

Riassunto

For some years, much of my leisure time has been devoted to the study of the anatomy, development, and habits of the Annulosa, and especially of Insects, on which subjects I have published various memoirs, chiefly in the Transactions of the Royal, Linnæan, and Entomological Societies: of these papers I subjoin a list. Although the details, of which these memoirs necessarily for the most part consist, offer little interest, excepting to those persons who are specially devoted to Entomology, still there are portions which, having reference to the nature of metamorphoses and to the origin of insects, are of a more general character. I have also briefly referred to these questions in a Monograph of the Collembola and Thysanura, recently published by the Ray Society, and in the Opening Address to the Biological Section of the British Association at Brighton in 1872. Under these circumstances, it has been suggested to me that a small volume, containing, at somewhat greater length, in a more accessible form, and with the advantage of illustrations, the conclusions to which I have been led on this interesting subject, might not be altogether without interest to the general reader. The result, which has already appeared in the pages of _Nature_, is now submitted to the public, with some additions. I am well aware that it has no pretence to be in any sense a complete treatise; that the subject itself is one as to which our knowledge is still very incomplete, and on which the highest authorities are much divided in opinion. Whatever differences of opinion, however, there may be as to the views here put forward, the facts on which they are based will, I believe, be found correct. On this point I speak with the more confidence, on account of the valuable assistance I have received from many friends: to Mr. and Mrs. Busk and Dr. Hooker I am especially indebted.
