Found in Lithuania 2015.06.21
Thank you

64. This is a Polygraphus female. A brush of hair on the forehead is clearly visible. This feature is found in two species, either Polygraphus subopacus Thomson, 1871 (which is very likely) or an invasive species from the Far East, Polygraphus proximus Blandford, 1894-Ussuri polygraph. The outbreak in the Moscow region was recorded for a long time.
According to the general habit of the beetle, the shape of the mace of the antennae, I am inclined to believe that this is the second option.
That would be even the size and number of segments of the antennae. It is on the second sign that they clearly differ.
