Adjust a little bit, and it works.

ListPlot[{{1, 2, 3, 5, 8}, {2, 3, 6, 9, 10}}, Joined -> True,
 PlotMarkers -> Automatic,
 Epilog ->
  Inset[Framed@
    Graphics[{{DotDashed, Line[{{1, 0}, {2, 0}}]},
      Text[Style["a", Bold, 8], {2.5, 0}], {Dotted,
       Line[{{1, -1}, {2, -1}}]},
      Text[Style["b", Bold, 8], {2.5, -1}]}, ImageSize -> 40,
     AspectRatio -> 0.4], {1.25, 7}]]
