Agonum emarginatum
I found this on the ground in my garden at night (it wasn't particularly close to the moth-trap so I'm assuming it wasn't attracted to the light). I used Hackston to get it to genus (though I was already in that ballpark) and intially Duff to get it to species. Some of the couplets were marginal in Duff so while I waited for the abdomen to clear I ran it through Hackston too - both led to emarginatum and Hackston provided some additional characters that helped separate it from viduum.
