(Original.) devour the stub, leaving themselves w'ithout food, and, being footless grubs, they of course perish. Plants of more than one-half inch diameter which become infested Avith larva? make very i^oor growth, being very slender, rarely reaching a height of more than 2 or 3 feet before tasseling (PI. II), and do not produce shoots or ears. Those that do not become infested until they are half grown may produce small ears. Each larva inhabits onh' the one burrow, and if, owing to any mishap, it becomes dislodged from it, it is powerless to rees- tablish itself. The larva does not become dislodged from the burrow.
