The former is that brush like cater- pillar, Fig. 87 a, black at the ends and chestnut red in the middle, that so often is found under boards and in out-buildings late in the fall and in the early spring. When disturbed, it rolls itself up hedgehog fashion. It forms its cocoon, Fig. 87 o, in May, and the perfect insect, Fig. 87 c, appears in June. This last is two inches and a quarter in expanse of wings. Its colour is yellow, with indistinct wavy lines on the primaries and with dark brown spots on all the wingp, and also on the abdomen. The secondaries are sometimes tinged with red. The larva of L. acrcea is the " salt-marsh caterpillar," the ravages of which have been so well described by Harris in his Insects. Injurious to Vegetation, pp. 351-355. It is about an inch and three-quarters in length and is clothed with long hairs, which are dark brown on the back and lighter brown on the sides Its spiracles are white. This caterpillar appears in June and attains its growth in the end of August, when it spins its cocoon. Of late years the numbers of the " Woolly Bears," as they are commonly called, have been greatly reduced by a fungus which spreads among them and destroys their NoCTUID-£. The Noctuids are the night-flying or owlet moths. Their name is derived from the Latin Noctua, an owl. These moths, on warm, moist evenings, often beat at the windows of our country houses, attracted by the light. In dress they are a sober " people"—browns and drabs prevail amongst them. But innocent as they are in appearance, they, through their larvse, work incalculable harm. Amongst these larvje are the various species commonly classed as &q
