How to remove one of several headlines…

Hey everyone, I’m trying to remove the third headline (h3, I guess) from my blog’s homepage. I’ve managed to hide it, lol, but I have yet to figure out how to remove it completely. I don’t want to mess with the other headlines, though (there are 4 of them, I believe).

If anyone knows how I can remove the headline — it appears directly above the post title “Giving credit to the architect…” but is hidden thanks to a white font (you can highlight to see it) — please, let me know! As always, your help is much appreciated.
