The interesting but detestable creature, the subject of these notes, does not seem hitherto to have inspired any enthusiasm in the antiquarian breast, for I have been unable to find any paper relating to it in the journals of archaeological societies. There is, however, a popular account in Princess Mary's Gift-book for 1914, consisting of a translation by the late Teixeira de Mattos of J. H. Fabre's story of the ant-lion and its habits, with a coloured plate, both of which accurately reproduce its pernicious activities.
