The insect breeds in sandy ground. The lar\-a is a small, whitish grub, and feeds on grass roots. In the fall it goes down lielow frost line, returning in spring and transform- ing. The adults come out in June. Eggs are laid in the ground, i to 4 inches below the surface. Egg- laying continues over a considerable period. There is one generation each year. Direct control is possible by spra^-ing thoroughly with arsenate of lead, 5 pounds to 50 gallons of water, to wliich should be added 1 gallon of molasses. Without the molasses the spray is not so effective, as the beetles mil avoid the parts of the plant that are coated with poison and seek out places where none of the spray has lodged. Spray first when the lieetles are due, and again in one week. Hand picking is feasible in flower gardens. If possible, break up the ad- jacent breeding grounds, especially The insect does not breed in ground.
