  Very recently the Dark Energy Survey (DES) Collaboration has released their
second group of Dwarf spheroidal (dSph) galaxy candidates. With the
publicly-available Pass 8 data of Fermi-LAT we search for $\gamma-$ray
emissions from the directions of these eight newly discovered dSph galaxy
candidates. No statistically significant $\gamma-$ray signal has been found in
the combined analysis of these sources. With the empirically estimated
J-factors of these sources, the constraint on the annihilation channel of
$\chi\chi \rightarrow \tau^{+}\tau^{-}$ is comparable to the bound set by the
joint analysis of fifteen previously known dSphs with kinematically constrained
J-factors for the dark matter mass $m_\chi>250$ GeV. In the direction of Tucana
III (DES J2356-5935), one of the nearest dSph galaxy candidates that is $\sim
25$ kpc away, there is a weak $\gamma-$ray signal and its peak test statistic
(TS) value for the dark matter annihilation channel $\chi\chi\rightarrow
\tau^{+}\tau^{-1}$ is $\approx 6.7$ at $m_\chi \sim 15$ GeV. The significance
of the possible signal likely increases with time. More data is highly needed
to pin down the physical origin of such a GeV excess.
