What does "infralapsarian" mean?

Infralapsarian: One of that class of Calvinists who consider the decree of election as contemplating the apostasy as past and the elect as being at the time of election in a fallen and guilty state; -- opposed to Supralapsarian. The former considered the election of grace as a remedy for an existing evil; the latter regarded the fall as a part of God's original purpose in regard to men.
