Are these the adelgids or Mindarus sp. aphids?

Thanks Charley. I heard Hemlock Woolly Adelgids were in Massachusetts, but this is the first time I've seen them.

 
I've been seeing them around my house for over ten years
but only recently have started seeing dying trees. When I check out the sick trees, it always seems to be the elongate hemlock scale that's to blame, rather than the adelgids.

 
Then I hope
that I don't see any of the elongate hemlock scales on my hemlock trees.

They look like adelgids to me
Doesn't look like any Mindarus sp. has been documented on Tsuga canadensis.
