   {Bombardier beetle} (Zool.), a kind of beetle ({Brachinus
      crepitans}), so called because, when disturbed, it makes
      an explosive discharge of a pungent and acrid vapor from
      its anal glands. The name is applied to other related
      species, as the {Brachinus displosor}, which can produce
      ten or twelve explosions successively. The common American
      species is {Brachinus fumans}.
