Female Prionus, maybe?


Let's see if the experts agree.

Female broad -necked root borer
Thank you for the ID. Is the stinger part at the rear harmful to people or used as a defense mechanism?

 
It's an ovipositor.
She uses it to lay her eggs in the soil. It serves no defensive purpose and cannot harm people.

 
Wonderful!
