H. F. Wilson This insect is quite common through- out the United States and may do con- siderable damage when abundant. The common name applied to the adults is given on account of an imaginary simi- larity in shape to a male buffalo. The mature insect is grass green in color, triangular in shape and with the prono- tum projecting strongly into sharp points in front. The summit of the pronotum forms a longitudinal line extending on a slant to the tip of the abdomen. The injury done by this insect is caused by the cutting of the twigs and limbs of trees and nursery stock for the purpose of depositing eggs. When abun- dant smaller limbs often become so badly scarred and injured that they become hidebound and cannot grow properly; as a result they are stunted and unthrifty. In addition, the scars form favorable receptacles for fungous growths and other insects. The habits and life history have been taken from C. L. Marlatt.
