Ectemnius decemmaculatus
Moved from Square-headed Wasps. Note the all-silvery frons above the insertion of the antennae. Tergum 1 also appears to have some red which sometimes occurs in this species but not in related ones. Ectemnius cephalotes has a continuous yellow band on tergum 5.

 
Thanks
Thanks for the correction, Matthias. Also for your comments explaining the difference. Greatly appreciated.

Moved

Tiphiid?
To my untrained eye it looks like a Square-headed Wasp which is just a guess, I do like trying to ID these.

Fun
Yes, they are fun to try to ID but I don't do very well I am afraid. Dr. Ascher has been very, very helpful to me. I really appreciate him taking the time to assist.

Keep up the good work. :)

 
yes, a square-headed wasp
Crabronini

I should be able to check the species ID in our collection soon.

Thanks John. Naomi made the correct call. Appreciate the species if you can check it.

Thanks to both,

 
Square head....
alright. but antennae and Red femur didn't ring a bell. :) But...you may well be right.
