The yellow-striped locust is one of our most common insects. It is readily known by its color, and by the two yellowish lines on the thorax, extend- ing, when the insect acquires wings, along the inner margin of the wing-covers. It is very troublesome in gardens, climbing upon the stems of beans, peas, and flowers, devour- ing the leaves and petals, and defiling them with its excre- ment. The young begin to appear in June, and they come to their growth and acquire their wings by the first of Au- gust. When about to moult, like other locusts; they cling to the stem of some plant, till the skin bursts and the insect withdraws its body and legs from it, and leaves the casi^skin still fastened to the plant. 3.
