The larva of Pelidnota punctata, whichis shown in Pig. 126, have been taken by me from rotten apple treestumps; and the beetles reported as doing considerable injury to thefoliage of grape-vines. A couple other beetles that belong to this familyhave been described in my various reports to the Horticultural and Agri-cultural societies of the state, where the reader is referred for a presenta-tion of their life-histories, Fio. 128.—Work of Hickory Borer, showing: longitudinal and cross section of stickwith burrows. One-half natural size,—[After Osborn, in Garden and ForeBt.\ Among the insects that are considered very injurious are the long-horned boring beetles (family Cerambyoid^). These insects are knownas the round-headed borers in distinction to those of the family Bu-prestidae which are called the flat-headed borers. While most of therepresentitives of the other family attack trees that have become injuredin some way and have their vitality lessened, the Cerambycidae on the other hand, mostly attackhealthy trees and oftenkill them outright in ashort time. Several ofthese insects have beendescribed in reports al-ready referred to in pre-^^ ceding pages of this paper.
