Milkweed Tussock Moth

Milkweed Tussock Moth "racing" with another moth - Euchaetes egle
Lyndeborough, Hillsborough County, New Hampshire, USA
September 7, 2008
These 2 caterpillars happened to be walking beside each other going in the same direction, as if racing. The one on the bottom walked a bit faster and passed the fluffier one. Two different species, I assume, but what are they?

How about
and
(more confident about the first than the second)

 
Thanks!
Thanks for the quick response.

The fluffy one looks like Euchaetes egle
or Milkweed Tussock Moth Caterpillar, AKA Milkweed Caterpillar.

Not sure on your other one though!
