The two sexes of these differgreatly : the males (Fig. ze) have wings, well developed featheryantennae, and the front legs thickly furnished with hair. Thegeneral color is ashy-gray, the front wings being crossed by un-dulated bands of darker shade, with two black markings on theouter edge near the tip, and a white spot on the inner edge,also near the tip. He may frequently be seen sitting on thetrunks of trees, or on the shady side of houses, etc., as he restsduring, the day, and flies only after dusk, often being attractedby light The female (Fig. 2a) is totally different from the.

Sheis of a pale gray color, the antennae being short and notfeathered, the legs rather slender and not covered with longhairs. {Riley.) In consequence of her wingless conditionthe female cannot fly ; after emerging from the chrysalis shecrawls upon the top of the cocoon where, after mating with themale, she deposits her eggs in a single mass, and soon afterdies. NUMBER OF BROODS In New England as a rule there appears to be but one brooda year of the Tussock-moth Caterpillars. These mature aboutmid-summer, spin cocoons and become moths late in July orearly in August. The eggs are at once deposited, to remainunhatched until the following spring. Further south there aretwo broods. NATURAL ENEMIES Fortunately this insect is at
