The ligula is either corneous or membraneous; its size and form varies greatly. The paraglossae are usually membranous; they reach their fullest development in the Carabidae, but as they are often entirely about the term ligula is frequently and synonymously with labium.

The second division of the body is the thorax, consisting of these segments variously marked. The first segment, the prothorax, is  separate from the other two and is usually freely movable. It consists of a dorsal surface, the pronotum, of one piece; at the sides the dorsal surface is usually inflexed forming the under surface of the prothorax. This inflexed portion is often called the prothoracic epipleura. The under surface of the prothorax consists of a central member and a pair of pieces each side; the first is the pro-
