Looe; Padstotv (Lamb) ; St. Mary's, Sdlly vittula, Redt. S. undulata, Kuts. S. nemorum, L. S. ochripes, Curt. exclamationis, Thunb. This genus, under the name of turnip fly, is only too well known throughout the county, as it at times works serious havoc on the turnip crop while still in the smooth leaf or cotyledon stage. P. nemorum is the dominant species, but in 1902 several fields about St. Columb were badly attacked by P. undulata. In the spring of 1903 the foliage of the early pota- toes at St. Mary's, Stilly, was injured by P. atra. A few years ago a field of dredge corn near St. Agnes was practically smothered with charlock, but about the beginning of June P. vittula was noticed in great numbers on the weed, and in a fortnight every visible charlock leaf was completely riddled Aphthona lutescens, Gyll.
