      [1913 Webster]

   2. (Zool.) Any one of several species of beetles whose
      larv[ae] gnaw the branches of trees so as to cause them to
      fall, especially the American oak pruner (Asemum
      m[oe]stum), whose larva eats the pith of oak branches,
      and when mature gnaws a circular furrow on the inside
      nearly to the bark. When the branches fall each contains a
      pupa.
