-XX:+UseParallelGC (aka "Parallel Scavenge") is a collector for the new generation portion of the heap (eden and Survivor spaces) which splits work between many threads; it can work with either the serial old generation collector (which is the default) or the parallel old generation collector (which does the same thing +UseParallelGC does, just for the old/tenured generation.) It cannot be used with the CMS (concurrent mark sweep) low-latency collecto.
-XX:+UseParNewGC is the same as UseParallelGC except that it's compatible with the CMS (concurrent mark sweep) low-latency collector (but it cannot be used with the Parallel Old collector.)
