Abstract
THIS is an exceedingly elaborate discussion of the nature of the various processes involved in the transformations of insects. We should have preferred to see it in larger book-form, with headings and text-illustrations; but reference to the subjects discussed is facilitated by a table of contents prefixed to the work. The chief problems are, of course, presented by insects, with complete metamorphoses, in which most of the larval structures are entirely dissipated during the pupa-state, and new ones formed for the use of the imago, whereas in the case of insects with incomplete metamorphoses the organs of the larva are gradually modified into those of the imago. It may be useful to condense Dr. Deegener's classification of larval organs:—
Die Metamorphose der Insekten.
