1607. Topsell, Four-f. Beasts (1658), 29. It is called a Formicarian Beare, for God hath so prouided, that whereas that Countrey is aboundantly annoyed with Emmets or Ants, that beast doth so prey and feed vpon them, that by the strength and vertuous humour of his tongue, the sillie poore inhabitants are exceedingly relieued from their greeuious and daungerous numbers. Ibid. (1658), Serpents 769. This formicarian or Pismire-like Phalanx, of Aetius is described to haue a body much resembling soote in colour, his necke ash-coloured, and his backe glistering, as it were with many starres on it.
