Horntail wasp
Appears to be Genus Urocerus, but I will let an expert proceed from here.

Thanks for your reply and information - greatly appreciated. I checked further using your description and was able to locate another reference which shows the same critter.

 
Yes.
Probably Urocerus gigas, but there is a fair amount of variability in coloration. Specimen is a female.
