After a larva is iuU-U'rown it ceases to eat and becomes restless, leav- ing the cabbage and crawl- in u" about. When these s}niptoms are seen, keep a larva un<ler a glass for observation. Note that it spins a mat of silk into which the claws of the last pair of prolegs are fastened, and a girdle of silk over the middle of its back. After it is thus securely fastened it draws its head down. When it has remained in this posi- tion for some time, the skin s[)lits over the head and thorax, and we hnd a <-hrysalis in placi- of the grei'n larva. Draw the j)Upa as it is fastened by its girdle. Search tor pupa' and make a list of places where they are found. Save as many as possible in order to see the butterllies emerge. Adult or imago. The rapid distribution of cabbage buttertlies is due to their ilight the country from garden to garden, and to th(^ conveyance of the chrysahs on cairiages and trains.
