pl. [Neut. pl. of Mod. Lat. haustellatus, from Cla . Lat. haustus =a drawing, haurio (pret. hausi )=to draw up or out. Used chiefly of water or other liquid.] 1. Entom .: The name given by Clairville, followed by Macleay, Stephens, and many others, to a subcla of insects consisting of those which, taking nothing but fluid aliment, have the organs of the mouth adapted solely for suction. They are placed in contrast to the Mandibulata, which have mandibles, or upper jaws. There are three leading types of suctorial mouth. In the Lepidoptera (Butterflies and Moths) there is a spiral proboscis called an antlia (q. v.); in the Rhyncota, or Hemipter a (the Bugs, .) a jointed rostrum; and in the Dip tera (two-winged flies), a fleshy proboscis. 2.
