Its large size and disgusting odor make it conspicuous. It is rusty black above and ochre-yellow be- neath. It passes the winter in the adult stage under boards, logs, or other cover- ing. It does not appear in the squash patch until late in the spring, often not until June or July. The eggs are laid on the under sides of the squash leaves in small patches. The young bugs when first hatched have a green body, with head, thorax and antennae pink. Two days after hatching, the body becomes ash-gray, and the other portions black. The young begin to suck the juices from the leaves, and the plant becomes sickly. Remedies.—Hand-picking when the adult bugs first appear in June, before the eggs are laid; crushing the eggs found on the under sides of the leaves; picking off the young, which when first hatched feed together in bunches; and trapping the bugs by lay- ing pieces of board on the ground near the hills and examining the under sides of them morning and evening, are the most effect- ive remedies. Trimming off the lower leaves of the plants, and laying them on the ground by the hills in place of the boards, is recommended. Kerosene emulsion (see page 9) has been used with good effect on the young bugs. Fertilizing helps the plants to withstand injury. Kansas Notes.—A correspondent in La Blanche, Sherman county, reported (June 5, 1391) that he had grown squashes for seed for four years and that his vines were first attacked in 1890. The bugs did not appear until July. In 1891 they appeared in May, and did much injury. HARLEQUIN CABBAGE BUG. (Murgantia histrionica Hahn; Order, Hemiptera.)
