   1. (Zo["o]l.)
      (a) A small beetle ({Anobium tessellatum} and other allied
          species). By forcibly striking its head against
          woodwork it makes a ticking sound, which is a call of
          the sexes to each other, but has been imagined by
          superstitious people to presage death.
      (b) A small wingless insect, of the family {Psocid[ae]},
          which makes a similar but fainter sound; -- called
          also {deathtick}.

                She is always seeing apparitions and hearing
                deathwatches.                     --Addison.

                I did not hear the dog howl, mother, or the
                deathwatch beat.                  --Tennyson.
