These butterflies are usually of medium size, but some of them are small; they are nearly always white, yellow, or orange, and are usually marked with black. They are the most abundant of all our butterflies, being common every- where in fields and roads. Some species are so abundant as to be serious pests, the larvae feeding on cultivated plants. The characteristic features of the venation of the wines are the following (Fig. 460): Vein V^ of the fore wings is more closely connected with radius than with cubitus, the latter appear- ing to be three-branched; vein Vj of the fore wings coalesces with radius for a considerable distance beyond the apex of the discal cell; and only three or four of the branches of radius remain distinct. In this family the fore legs are well developed in both sexes, there being no tendency to their reduc- tion in size, as in the two following families. The larvse are usual- ly slender green worms clothed with short, fine Fig. of/^.«^/a ^r^/^^ hairs; the well-known Cabbage-worms are typical illus- trations (Fig. 461). The chrysalids are supported by the tail and by a loose girth around the middle. They may be distinguished at a glance by the presence of a single pointed projection in front (Fig. 461)..
