Now the various parts in the _head_ division are, to speak generally, the _head proper_, the _mouth_, the _eyes_, and the _antennæ_. Entomologists describe a large number of other parts, which would also be mentioned here if this little treatise were intended to give a minute account of the insect's anatomy; and those features which are of most prominence and importance, will be mentioned in addition when we come to speak particularly of these several chief organs. The middle portion of the insect, or _thorax_, is divided into three parts--a front, middle, and hinder part; or, in the language of entomology, a _pro-thorax_, a _meso-thorax_, and a _meta-thorax_. Attached to the thorax are the _wings_ and the _legs_. The remaining portion, or _abdomen_, is furnished with organs and appendages, not requiring special mention in this place. [Illustration: _Eyes of a Bee._] Let us consider briefly the organs which are seated in these divisions; and, beginning with the head, let us glean a few particulars upon that most interesting topic--the eyes of insects. We might well fill a volume with this subject alone, for truly it is almost inexhaustible. In the other sections of the animal kingdom, the eyes, though organs of the highest importance, are, nevertheless, simple, and little varied in their number and arrangement. But in insects, whether we consider their number, their structure, their arrangement, or their size, we are lost in amazement at finding these organs assume an importance in the insect's economy, of which we have no parallel elsewhere. Look, for example, at the accompanying representation of the eyes of a bee, and then let us ask whether, in all the world beside, we can find a creature whose two eyes are larger than all the rest of its head put together? What should we think of a quadruped as large as a bull, whose eyes occupied great part of its head, its forehead, and the greater portion of its face? What astonishing powers of sight it would possess! [Illustration]
