Didymocantha obliqua was my first thought but the elytral markings are much more vague and indistinct than I have seen on other individuals. Additionally, the darkened 3rd antennal segment seems to be not quite right for D. obliqua.

Usually pattern being more vague is a matter of wear and tear (more attributable to a specimen’s age than its species), but agree the dark antennomere III, is a bit unusual for D. obliqua.
