Western Conifer Seed Bug in front garden

In the afternoon of Saturday October 19th, at about 4pm in the front garden I saw a large brown bug on the wall of the house just left of the front door. I moved it to a bush and took a few pics. I could not find it in my insect book (published in 1996!), I wondered if it was some kind of Longhorn beetle? Jane F kindly ID'd for me as a Western Conifer Seed Bug, no woder I couldn't find it as it was an American species that was introduced to the UK in 2007.
