sqlite3 ~/Library/Application\ Support/Google/Chrome/Default/History "delete from urls where url like '%removeme.com%';"

Use the above command to purge specific history items (in this case ‘removeme.com’) from your Google Chrome history on a Mac OS X! This saved me time at work purging old invalid URLs that Chrome kept suggesting for me…. Its just a sqlite database, so you’re free to manipulate it in a number of other ways if you’d like.
