Extract

This description is based on an examination of 25 larvae of Hylobius radicis Buch. recovered from the damaged root-collars of dead and dying Scots pine, Pinus sylvestris L., in the vicinity of Angus, Ontario. Since larvae of at least one species of the genus Pissodes (P. approximatus Hopk.) may be found in the same trees, I am also taking this opportunity to compare the external structures of the larva of H. rardicis with those of the genus Pissodes (see Böving, 1929; Anderson, 1947). Where possible, and particularly in the description of the head capsule and mouth parts, the terminology used is that of Anderson.
