Hoc in LLPSI Orberg scripsit (Aeneas Kathaginem devenit Venusque, mater sua, ei dicit...)
'...Quicumque es, dis caelestibus carus esse videris, qui ad urbem Karthaginem adveneris.'
Videris: 1) Pres. 2nd Pers. Sing. Passive; 2) Fut. Perf. 2nd Pers. Sing. Active; 3) Perf. Subj. 2nd Pers. Sing. Active.
Adveneris: Perf. Sub. aut Fut. Perf. Orberg dicit ut 'conj.' sit.
I'm guessing Fut. Perf. for Videris and, following Orberg's direction, 'adveneris' has got to be perf. subjunctive.
So: 'Whoever you are, by the Gods you shall have seen that you were safe by (because you entered) coming to Carthage....'
