Collected by sifting wrack deposits along the rocky coast at the annual all-taxa BioBlitz hosted by the Seacoast Science Center. I could have had live ones to photograph but I killed them just as our beetle expert was putting away his scope and now must shoot and post to get IDs of these dead specimens. (It would not have been necessary to collect/kill so many but at this size I couldn't tell if they were all the same species, which they appear to be. There is some variation in size and shape of markings but not much.)

I think this will be a new species for bugguide.
