Looks like mealybugs to me, too. You can wash them off with a spray of water, but they will just go to another plant. Sometimes I will take my fingers and wipe off the white. The actual "bug" will jump off and go somewhere else once disturbed. If you see more on other plants, you may want to take more proactive steps to get rid of them. I was spraying Roundup today and noticed mealybugs on several different plants and shrubs as I walked around.
