The Southern Cabbage Butterfly—Pieris protodice. By W. Saunders, London, Ontario. In figure 1 we have represented the male, and in figure 2 the female of the Southern Cabbage Butterfly, an insect by no means confined to the South, although much more abundant there than in the more northerly portions of America. This insect enjoys a wide geographical distribution, extending south-west as far as Texas, west to Mis- souri, north-west to the Red River, and along the east from Connecticut to the Southern Atlantic States. A few years ago it was not uncommon around Lon- don, and occasionally quite plentiful about the shore of Lake Erie at Port Stanley ; but of late years it has become a rare insect with us, and we have not met with a specimen on the wing for several years. The English Cabbage Butterfly, Pieris rapes, seems to have taken its place entirely. The butterfly is a very pretty one, as will be seen by the figures. The ground colour in both sexes is white, with black spots and black and dusky markings which are much more numerous in the female than in the male. Although so ljare in Ontario that it has never, as far as we know, been reported as injurious, it is frequently very destructive to the south of us.
