CONTENTS.
CHAPTER I.
THE CLASSIFICATION OF INSECTS.
Introduction.—Stages in the Life of an Insect.—Classification
of Insects.—Characters derived from the Wings; from the parts
of the Mouth; from the Metamorphoses.—The Classes of Insects:
Hymenoptera, Strepsiptera, Coleoptera, Euplexoptera,
Orthoptera, Thysanoptera, Neuroptera, Trichoptera, Diptera,
Aphaniptera, Heteroptera, Homoptera, Lepidoptera _page_ 1-26
CHAPTER II.
THE INFLUENCE OF EXTERNAL CONDITIONS ON THE FORM AND STRUCTURE
OF LARVÆ.
Larvæ depend partly on the group to which they
belong.—Wood-eating Larvæ.—Larvæ of Lamellicorns.—Larvæ
depend also in part on mode of life.—Larvæ of Hymenoptera, of
_Sirex_; of _Tenthredo_; of Ichneumons; of Bees.—Rudimentary
legs of Bee Embryo.—Beetles, _Weevils_, _Scolytus_,
_Crioceris_, _Sitaris_, Metamorphoses of Pteromalidæ.
_Platygaster_, _Polynema_.—Influence of external
conditions.—Developmental and adaptive Metamorphoses _page_ 27-41
CHAPTER III.
THE NATURE OF METAMORPHOSES.
The life history of an Insect must be considered as a
whole.—Vagueness of the term Larva.—Some larvæ much more
advanced than others.—Organs develope in different order, in
different groups.—Suppressed stages.—Apod condition of
_Phryganea_; of _Aphis_; of
_Chrysopa_.—Libellulidæ.—_Donacia_.—Spiders.—Myriapods.—Apod
stage of Homomorphous Insects once probably longer than
now.—Suppression of embryonic stages.—Metamorphoses of
Hydroida, Crustacea, Isopods, and
Amphipods.—Echinoderms.—Variations in development induced by
the influence of external conditions. _page_ 41-62
