  We report the results from a detailed $\gamma-$ray investigation in the field
of two "dark accelerators", HESS J1745-303 and HESS J1741-302, with $6.9$ years
of data obtained by the Fermi Large Area Telescope. For HESS J1745-303, we
found that its MeV-GeV emission is mainly originated from the "Region A" of the
TeV feature. Its $\gamma-$ray spectrum can be modeled with a single power-law
with a photon index of $\Gamma\sim2.5$ from few hundreds MeV to TeV. Moreover,
an elongated feature, which extends from "Region A" toward northwest for
$\sim1.3^{\circ}$, is discovered for the first time. The orientation of this
feature is similar to that of a large scale atomic/molecular gas distribution.
For HESS J1741-302, our analysis does not yield any MeV-GeV counterpart for
this unidentified TeV source. On the other hand, we have detected a new point
source, Fermi J1740.1-3013, serendipitously. Its spectrum is apparently curved
which resembles that of a $\gamma-$ray pulsar. This makes it possibly
associated with PSR B1737-20 or PSR J1739-3023.
