Strange beetle on Hemerocallis

Observation - Strange beetle on Hemerocallis. Description: I was surprised to find this rather large and striking beetle in a garden I was working in this afternoon. It was about 3 - 3.5cm long, tip to tail and was sitting quite happily on some Hemerocallis leaves. Can anyone tell me what it is?
