Overall, satellites with $\mstar\sim10^9\msun$ (similar to the Magellanic Clouds) represent the transition between gas consumption and gas stripping, and no quenching mechanism (either internal or external) appears to operate efficiently near this mass \citep[see also][]{Weisz2015}.
Finally, we note that the above scenario may explain the curious, though qualitative, similarity of Figure~\ref{fig:quench_times} with the mass dependence of the underlying galaxy-halo $\mstar/\mvir$ relation, which
also is low at both high and low $\mstar$ and peaks at $\mstar\sim10^{10}\msun$ \citep[e.g.,][]{Behroozi2013c}.
In particular, at high $\mstar$, the same physical process(es) that lowers $\mstar/\mvir$ also lowers a galaxy's cold gas fraction, which in turn causes more massive satellites to quench more
rapidly. rapidly, absent accretion.
At low $\mstar$, the same shallower potential wells that
allow internal cause stellar feedback to lower $\mstar/\mvir$ also allows external stripping to occur more easily and
thus quenching to occur more rapidly.
While preparing this letter, we became aware of Fillingham et al.~2015 (submitted), who also used ELVIS to constrain the quenching timescales of satellites of the MW/M31.
