  We report the discovery of the eighth and ninth known Trojans in stable
orbits around Neptune's leading Lagrange point, L4. The objects 2014 QO$_{441}$
and 2014 QP$_{441}$ were detected in data obtained during the 2013-14 and
2014-15 observing seasons by the Dark Energy Survey, using the Dark Energy
Camera (DECam) on the 4-meter Blanco telescope at Cerro Tololo Inter-American
Observatory. Both are in high-inclination orbits (18.8$^{\circ}$ and
19.4$^{\circ}$ respectively). With an eccentricity of 0.104, 2014 QO$_{441}$
has the most eccentric orbit of the eleven known stable Neptune Trojans. Here
we describe the search procedure and investigate the objects' long-term
dynamical stability and physical properties.
