Norwich, Yarmouth, Thetford, Gillingham, Horning, Hick- ling, Clenchwarton, Lyng, Barton ; for- merly plentiful, but now apparently extinct in some of these localities, and generally greatly reduced in numbers Hypogymna dispar, Linn. At the beginning of the present century, or the end of the last, very plentiful at Horning, where Curtis found it flourishing in such abun- dance that ' eggs, caterpillars, chrysa- lides and moths ' could all be collected by him upon the same day. It was also found at Cawston, and there con- tinued until the year 1861, since which period it has not, I think, been observed at large in the county, and scarcely in any other part of the British Isles Psilura monacha, Linn.
