The females live and die Ijeneath their scales, never leavhiR them ; but in April the males molt fo: the last time, and soon thereafter emerge from under their scales as minute, active with fully-develoi>ed wings. After mating the males die. In May. possibly earlier, under favouralile conditions, the females begin to give birth to living young, and may continue to prfMluce for si.\ weeks or longer.
