Under the system of clover growing practiced in New York little can be done to prevent injury by the root- borer. Something may be gained, how- ever, by adopting a short rotation, by keeping the soil in good tilth, by main- taining a high state of fertility, and by underdraining wherever necessary. THE CLOVER LEAF-WEEVIL, Ilypera punctata Fabricius While capable of doing serious injury under favorable condi- tions the clover leaf-weevil does not as a rule cause as much loss as the clover root-ljorer. This beetle is a native of Europe and was apparently introduced into North America about the middle of the nineteenth century, but did not attract attention by its injuries to clover until the early eighties when it was reported as destructive in Yates County, N. Y. It is now widely dis- tributed throughout the state and every year causes more or less loss, although serious outbreaks are usually local in extent and rarely ooiitinue froin year to year in the same locality. The insect passes the winter in the larval condition, most of the larvae being in the earlier stages. With the advent of warm weather in the spring these grubs begin feeding on the clover leaves and comjjlete their growth by about the middle of June. The full-grown larva is one-third to one-half inch in length, green in color with a light stripe down the middle of the back; the head is l)rownish. The grubs feed mostly at night and during the day can be found curled up under the rubbish around the base of the plant. The younger grubs eat small holes through the leaves and the older ones devour larger areas, beginning at the edge of the leaf. When full-gTow
