If it's one or the other, I'd rather be
Melina.
Erlea is pretty. But it looks like it could be mispronounced "early" where I live.
I actually struck
Melina off my short list for a daughter's name because of the medical term melena, though. If it were any "bee" name, I'd go with
Melissa. Even though
Melissa was a big fad, it's still classic, and I really like it.
