ANTLIA

The oral instrument of Lepidopterous insects, in which the ordinary trophi, or instruments for obtaining, are replaced by a spiral, bipartite, tubular machine for suction, with its appendages. It principally consists of the solenaria, or two lateral sub cylindrical tubes, and the fistula, or intermediate sub quadrangular pipe, formed by the union of the two solenaria, which intermediate canal conveys the nectar to the pharynx. Theoretically, the solenaria are the maxillae inordinately elongated, and they support at their bases two minute palpi. Rudiments of the upp«r lip or labrum, and mandibles, exist above the maxillae; and below these is the labrum, attached to the head, and distinguished by a pair of large palpi. [s. 74]
