Graphium agetes, the fourbar swordtail, is a widespread species of swallowtail butterfly found in tropical Asia.

Forewing: cell crossed by three comparatively broad, oblique black bands, the innermost produced across interspaces 1 and la to the dorsal margin, the next to vein 1, sometimes a little beyond into interspace 1a, the third to the median vein; these are followed by a triangular costal black spot above the upper apex of the cell; a postdiscal oblique band similar to the others that extends from the costa to just above the tornus, where it joins a broad black terminal edging that lies between the apex of the wing and the tornus; the costal margin edged with a black thread which widens slightly beyond the postdiscal band.

Hindwing: a spot at the tornal angle, the anal lobe, tail and terminal margin black; above the tornal spot is a short, comparatively broad, red band edged anteriorly by a fine black line that joins the spot to the black on the anal lobe; superposed on the black of the terminal margin there are some obscure white scalings; a triangular transverse subterminal white spot in interspace 3 and occasionally a sub-terminal short white line in interspace 4; also the anterior edge of the tail at base is touched with white.

Underside similar; hindwing with the addition of the two black bands mentioned above, which coalesce above the tornal area.
