Ectemnius Sp
This has a silvery face thus not E cavifrons. The other suggestions were E literatus or E cephalotes.
Thanks to Tim Strudwick for comments.
So is there enough information in the photographs to do it.
The closest I could come was this top picture from Steven Falk's Flicker Album for Hogweed Fly Fox ♂︎ (Ectemnius literatus)

The spines at the end of abdomen show this to be a male. They use them for territorial disputes. Seen a number of times with Common Carder Bees as they were feeding on the Lambs Ears.
Most of pictures clearly show the spines.
