  Using $e^+e^-$ collision data corresponding to a total integrated luminosity
of 12.9 $fb^{-1}$ collected with the BESIII detector at the BEPCII collider,
the exclusive Born cross sections and the effective form factors of the
reaction $e^+e^-\rightarrow\Xi^{-}\bar\Xi^{+}$ are measured via the single
baryon-tag method at 23 center-of-mass energies between 3.510 and 4.843 GeV.
Evidence for the decay $\psi(3770)\rightarrow\Xi^{-}\bar\Xi^{+}$ is observed
with a significance of 4.5$\sigma$ by analyzing the measured cross sections
together with earlier BESIII results. For the other charmonium(-like) states
$\psi(4040)$, $\psi(4160)$, $Y(4230)$, $Y(4360)$, $\psi(4415)$, and $Y(4660)$,
no significant signal of their decay to $\Xi^-\bar \Xi^+$ is found. For these
states, upper limits of the products of the branching fraction and the
electronic partial width at the 90% confidence level are provided.
