Deporaus (L.) This species of leaf-rolling beetle isabundant in many parts of the country,but I have found it most plentifully atKielder, Northumberland. The leaves(of birch) are cut much in the samemanner as by the preceding species, butthe case is rolled lengthwise insteadof in a globular form (fig. 67). Therolled portion somewhat resembles akind of paper bag used by grocers orconfectioners, and made by rolling a square-cut piece of paper roundthe hand. The chief injuries are done by the female insect: sheinterferes only with the vitality of a certain portion of the leaf. Shebegins rolling operations by making an incision on the outer edge of.
