Mouth.—The mouth of Colcoptcra is niandibulate ; that is to say, it possesses two pairs of horizontally moving pieces for the purpose of seizing the food. Above it is seen a small piece arti- culating with the front or epistoma, which is called the upper lip, or labrum. Immediately below the labrum are the jaws, or mandibles; they are of various shapes, but are gpnerally curved and of mode- rate size; exceptionally, in certain Lucauidas, they are very long and branched, like the antlers of a deer; at other times, as in certain Scaraboeidae, thoy are very small and partly membranous. The form of the joint between the mandibles and the head varies somewhat, and has been used by Duval for the purpose of defining some genera of Buprestidse. Below the mandibles is a second pair of horizontally moving pieces, called maxillas; they are complex in structure, and are of great moment in classification, and therefore demand a special paragraph. MAXiLiiiE.—The hind portion or base of the maxillae is com- posed of two pieces ; the one articulating with the head is called the cardo, the second piece the stipes; attached to the stipes are the appendages, which are normally two hhes and one maxillary palpus; the lobes are varied in form, according to the families and genera, and sometimes one or the other is so small as to be indistinct; the outer lobe is occasionally, as in Cicindclidffi, Cara-.
