Thanks for the ID, Boris
and the (broken) link to that Nova Scotia reference.

If I had replied directly to your comment, you wouldn't be able to fix the link to the reference you gave: the "bugguide.net/" portion at the beginning should be removed.

Moved
Moved from Calligrapha.
Keyed with this reference:
dark epipleuron (visible on bottom right specimen) is diagnostic.

might be scalaris
and if so, it might be the first provincial record (unless someone has recorded it since this 1991 PDF list) and probably an eastward range extension, as New Jersey is on the northeast coast of NB.
A similar image here is labeled tiliae but I don't know how reliable the ID is; other similar images from Montreal are labeled scalaris.
I suspect that some species have been reclassified and/or lumped recently - Mike Quinn reported here that there are 13 species of Calligrapha known from Ontario, whereas 24 species are listed in the 1991 link above. I haven't seen photos of alnicola, confluens, ignota, vicina, or virginea which supposedly occur in New Brunswick.
