locusts A well-known plague in Palestine and neighbouring countries: see for descriptions both of their immense numbers, and of their ravages, the writer's notes on Joel (in the Camb. Bible), pp. 37 39, 48 53, 87 91. They do not however seem to visit Egypt very frequently. Niebuhr (as cited by Kn.) witnessed at Cairo in January a great swarm of locusts blown up by a SW. wind from the Libyan desert: Lepsius (Letters, p. 104) describes one in March, coming up also from the SW., which covered the whole country far and near. Denon (Voyages dans la basse et la haute Égypte, 1807, i. 287) describes one brought up by the wind from the East, which eventually, when the wind changed, was driven back into the desert.
