Size: aphid size
Stalk of green chard bearing black aphids and another kind of black bug. The second kind has white markings. What is the second kind?

Moved from Aphids.

This is Aphis sp., probably Aphis fabae Scopoli, a.k.a. black bean aphid.

Moved from ID Request.

Are the white-marked bugs also aphids, then?

I'd say...
...yes. The cornicles on the posterior are usually the dead give away. See the info page for more explanation.
