Very unusual wasp Toby! I wonder what that thing is going over it's back, I haven't seen anything like that before at least not that I remember!
As you might know, these are extremely difficult but the extra thing it has might be a clue.
Much I'm seeing looks to fit the family Platygastridae, the antennae look to have 8-segmented flagellum (the bit between the tip and the bottom joints), shiny black body, wings with little veination, and size, all match up. Platygastridae - Wikipedia, the free encyclopedia
Happy hunting..

Pretty wasp the second one, can't be sure but most metallic wasps are Chalcids. |

Toby
It's a scelionid wasp of some sort (family - Platygastridae as JRS bugs suggested).
The peculiar horn is part of the abdomen - no idea what it might be used for - but it could be to house the ovipositor.

I forgot to mention, number 1 is a scelionid - I've not looked at number 2 yet.

You might want to see what you can find on the scelionid tribe - Baeini as I think it's this tribe where some of the species have the peculiar metasomal horn. I think all the species in this tribe are egg parasites, so you might have found yourself an interesting egg parasitoid.
Nice to see

As Janet said, number 2 is a chalcid, so another parasitoid, but any more than that I don't know. Identifying one of these from a photo is a veritable mine-field.

Microterys has patterned wings, only a guess.... Microteryini
Here's a few pages of pics to browse.. Universal Chalcidoidea Database |

thanks for info from which I was able to discover:
Females of the genus Inostemma are conspicuous because of the curved, tubular "horn" that arises from the dorsum of the 1st abdominal segment, extending over the thorax to the head. | | | |
