What is it?

A couple of weeks ago, I posted a photo of one of these wee critters (the littler ones), curious because there were at that time so many, so frequently.

I spent some time trying to identify them, establishing that they are very like longhorn beetles but far smaller that those typically are.

I think the larger beetle here is most likely a Burnt Pine Longhorn, and shows the similarity of form. But what is the tiny one?

I have finally booked my movers, for Monday. In the interim I am doing admin related work and playing nice with my clients (who are also relatives) visiting from Australia.
