The four short horns Fig. 149. on their shoulders are also notched, and, like most other Sphinges, they have a long and stiff spine on the hinder extremity of the body. They enter the earth to become chrysalids, and pass the winter, and come forth in the winged state in the month of June following, at which time the moths may often be found on the trunks of trees, or on fences in the vicinity. In this state their wings expand nearly five inches, are of a light brown color, variegated with dark brown and white, and the hinder part of the body is marked with five longitudinal dark brown lines. A young friend of mine, in Boston, once captured on the trunks of the trees a large number of these moths during a morning's walk in the Mall, although obliged to be on the alert to escape from the guardians of the Common, whose duty it was to prevent the grass from being trodden down. Nearly all of these specimens were females, ready to deposit their eggs, with which their large bodies were completely filled. On being taken they made scarcely any efforts to escape, and were safely carried away. It would not be difficult, by such means, very considerably to reduce the number of these destructive insects; in addition to which it might be expedient, during the proper season, for our city authorities to employ persons to gather and kill every morning the cat- erpillars which may be found in those public walks where they abound. From the genus Sphinx I have separated another group.
