Papilio \Pa*pil"i*o\, n. [L., a butterfly.] (Zo["o]l.)
   A genus of butterflies.

   Note: Formerly it included numerous species which are now
         placed in other genera. By many writers it is now
         restricted to the swallow-tailed butterflies, like
         {Papilio polyxenes, or asterias}, and related species.
