You've got good old fashioned mealy bugs. They love to migrate from plant to plant, so isolate this one from your other plants, and check all others carefully for the next few weeks. As to getting rid of them, dip a Qtip in rubbing alcohol, and rub them off the plant. Change Qtips every few dips, so you'll do a good job of removing the bugs and the fuzzy egg nests. Check also the back sides of leaves and stems, and especially check the angles where one branch comes off another -- this is where you'll see the fuzzy webs, in which the eggs are hidden. You'll have to keep at this alcohol treatment every day for a couple of weeks, because the larvae will hatch out, and also because you'll miss a few. Google up "systemic pesticide" for info about chemicals you can put right on the potting soil, to enter the plant via the root system to minimize pests.
