An Introduction to Entomology: Vol. 4 or Elements of the Natural History of the Insects

An entomologist who aspires to more than the character of a mere amateur, will not be content with filling his cabinet with nameless objects for the sole amusement of the eye; b...

It was by the language of _terms_ that he invented and employed, as well as by his system and methods of arrangement, that Linné smoothed the way to the study of Natural History...

"Life and flame have this in common," says Cuvier, "that neither the one nor the other can subsist without _air_; all living beings, from man to the most minute vegetable, peris...

After the very general idea that I have attempted to embody for you of the _System of Insects_; of the groups in which nature has arranged them, and their mutual relations; it w...

Having in my last letter given you some account of the _haunts_ of insects, I now proceed to describe the various _instruments_ with which you ought to be provided, to enable yo...

Having given you this full account of the _external_ parts of insects, and their most remarkable variations; I must next direct your attention to such discoveries as have been m...

We have seen upon a former occasion the great variety of movements that insects can perform, and of the _external_ organs with which they perform them[801]: but we are now to co...

conduct us to what are denominated its _genera_; but upon these last it will not be a waste of your time to enlarge a little. In the last edition of the _Systema Naturæ_, and in...

of torpidity, in which they remain chiefly without motion, it will not seem wonderful, should any partial moisture accidentally accumulate upon them, that it affords a seed plot...

Having given you so full an account of the system of _digestion_ in insects, I am now to say something concerning their _secretions_, and the organs by which they are elaborated...

"The immense Class of insects," says the immortal Cuvier, "in the structure of its alimentary canal exhibits as many variations as those of all the vertebrate animals together:...

At first one would think that the _senses_ of insects might be described in very few words, and scarcely afford matter for a separate letter; but when we find that physiologists...

The reproductive organs of insects in their _general_ denominations and functions correspond with those of the higher classes of animals; but as to _number_, _proportions_, and...

We learn from the highest authority, that the _blood_ is the _life_ of the animal[348]: every object of creation, therefore, that is gifted with animal life, we may conclude, in...

insects relates to their _representation_ of each other. Here we may observe, that some insects represent each other only in their _form_; others also in their _function_; and o...

Though no subject is more worthy of the attention of the Entomologist than the _Geographical Distribution_ of insects, yet perhaps there is none connected with the science, for...

Having laid before you what observations I thought might sufficiently explain all the principal features of the Anatomy of insects both external and internal, you will next expe...

Having considered insects as to their History, Anatomy and Physiology, we must next enter a new and ample field, in which, like most of our predecessors, we shall often be perpl...
