a terminal joint, the digitars.
Beneath the maxillae and between them, forming the floor of the mouth are the mentum and labium.
The mentum articulates with the anterior margin of the gula. It varies greatly in size and shape, being usually small or moderate in size and trapezoidal or quadrate, or frequently large in size. In the Carabidae it is deeply emarginate in front, usually with a prominence or tooth in the middle. When deeply emarginate the lateral portions of the mentum are called the lobes; these are bordered on the inner side by a narrow piece somewhat inflexed, extending even to the bottom of the emargination and aiding in the formation of the tooth, these are the epilobes of the mentum. At the outer apical angles of the mentum is the palpiger, which bears the labial palpus.
This palpus is usually three jointed, occasionally four or two jointed, sometimes even filamentous and not divided.
The labium is placed usually in front of the
