   F. scarab['e]e.]
   1. (Zool.) Any one of numerous species of lamellicorn beetles
      of the genus Scarabaeus, or family Scarabaeidae,

   2. (Egyptian Archaeology, Jewelry) A stylized representation
      of a scarab beetle carved in stone or faience, or made in
      baked clay, usually in a conventionalized form in which
      the beetle has its legs held closely at its sides, and
      commonly having an inscription on the flat underside; -- a

      scarab [the carved stone itelf].

The Devil's Dictionary (1881-1906):

SCARABEE, n.  The same as scarabaeus.

                He fell by his own hand
                    Beneath the great oak tree.
                He'd traveled in a foreign land.
                He tried to make her understand
                The dance that's called the Saraband,
                    But he called it Scarabee.
    He had called it so through an afternoon,
        And she, the light of his harem if so might be,
        Had smiled and said naught.  O the body was fair to see,
    All frosted there in the shine o' the moon --
                        Dead for a Scarabee
    And a recollection that came too late.
                            O Fate!
                    They buried him where he lay,
                    He sleeps awaiting the Day,
                            In state,
    And two Possible Puns, moon-eyed and wan,
    Gloom over the grave and then move on.
                        Dead for a Scarabee!
