Crossocerus impressifrons (MD)
The absence of yellow spots on the abdomen separate this species from Ectemnius and Lestica. Yellow bands on the pronotum and scutellum and the yellow tibiae make this one of the few readily recognisable species in the genus.

Crabroninae.
Might be genus Crossocerus, but can't be positive. Certainly a square-headed wasp, subfamily Crabroninae.
