When full-grown the larvas arcabout three-quarters of an inch long, and fromtheir greatly increased size, make their presencercadilj known by the sudden disappearance ofthe leaves from the infested bushes. Shortlyafterwards, having attained a length of fullythree-quarters of an iuch, they burrow under-ground, generally beneath the infested bushes,or, if there are many leaves hing on the ground,simply hide under those leaves. In either casethey spin around themselves a thin oval cocoonof brown silk, within which they assume thepupastate. But frequently, as we are assured byMr. Saunders of Canada West, and as Europeanobservers have noticed, they spin their cocoonsin the open air upon the bushes. About thelast week in June or the first part of July, oroccasionally not until the beginning of August,the winged insect bursts forth from the cocoonand
