Like to consult you on this one.
In an area with normally a lot of Ch. urbana and a few Ch. psilophthalma, today I got 3 very similar males bergenstammi-group from willow satkins. The frons is strongly, but not totally, silvery. This suggests uviformis (= argentifrons). The third antennal segment is black and seems short. The dusting on the sternites is not so convincing.
