Two captions in one line for two different tikzpictures

Question

I created these figures in tikzpictures. The two left ones are the first figure and the two right ones are the second figure.

How can I give them two separate captions respectively while keep both figures next to each other? If I add a second caption, the second figure always goes to the next line.

The desired outcome is:

Thank you for editing @Bobyandbob. I'll try to follow these standards in the future. — XsLiar, Nov 21 '17 at 20:34
Hi @Cragfelt! Yes and unfortunately it also forces the second figure (the two last circles) in the next line. — XsLiar, Nov 21 '17 at 21:09
Do you need 2 Subcaption(1xtwo left ones and 1xtwo right ones) and the caption of the whole figure? Or do you need also the shown Captions ( Q, V-Q,Q and V-Q)? — Bobyandbob, Nov 21 '17 at 21:13
@Bobyandbob I apologise for being not clear enough. I also added a picture of the desired outcome now. (Sorry for the large size). I need 2 Captions (1xtwo left ones and 1xtwo right ones). The two left circles as well as the two right circles should be seen as a whole figure respectively. I also have to keep the subcaptions (Q, V-Q, Q and V-Q).Thus I do not need a caption of the whole figure. — XsLiar, Nov 21 '17 at 21:21
@HenriMenke thanks for your hint. I tried to include minipage environments, since this is my usual solution. However it seems like using minipage around the subfigures does not really lead to the desired outcome unfortunately. — XsLiar, Nov 21 '17 at 21:39

I'd use tabular and two minipages for the two captions.

Thank you @egreg. That is indeed exactly what I was looking for! I already accepted Bobyandbob's answer, but I really appreciate your help. — XsLiar, Nov 21 '17 at 21:54
@XsLiar Don't worry, I have enough points to call it a reputation. ;-) — egreg, Nov 21 '17 at 22:03
XsLiar: I think my solution isen't helpful and not so good. The answer mentioned in the comments Two figures side by side and also @egregs answer fits your question much better. I will delete my answer if its okay for you. Nevertheless you could switch to this answer and accept. — Bobyandbob, Nov 21 '17 at 22:03

@XsLiarOh i can't deleted my question, before you switch to egregs answer. So you have to decide. — Bobyandbob, Nov 21 '17 at 22:08
@Bobyandbob. To be fair egregs answer fits my question better, but your answer actually provided a solution I had not in mind and which I find more suitable now. Perhaps I did not know what I was really looking for :) I will gladly stick to your answer. Thanks to both of you! — XsLiar, Nov 21 '17 at 22:13

Update: Refering to your comment. Here is a solution with Figure1 instead of the AAAA and Figure2 instead of the BBBB. So both figures will be listed themselves. The solution is similar/equivalent to Two figures side by side.

Like this?

Similiar to my answer here you can do it like this below. The labels Q, V-Q, Q and V-Q are added with simple \nodes. Instead of subfigure i usd subfloat.I also have scaled your ellipsis a little bit, hope its okay.
