ventrolateral angle showing the epipleuron might be useful

I can add that
It is partially pale; do you suppose the form of the spermatheca is useful with these?

i'll run it past Dr G.-Z. first

Looks similar to this from Mi
Looks similar to this from Minnesota, which Dr. G-Z said "no clue!"

Dr. G-Z says "no clue!" again....
here's his comment (pers.comm.): "In the thread about these pictures, there is a neat comparison of this specimen with another from Minnesota. I entirely agree that they are conspecific, and I have the same comment for the new one: no clue! I have collected specimens looking like these too, and not even with the genetic data that we commonly gather from these animals, I am able to establish any robust affinity. I recall that they are not consistently found on the same plant species, but it would be an interesting addition if someone figures out the plant where the insect was found. These animals seem to merge characteristics of C. philadelphica (L.) or C. amelia Knab (humeral markings are typical of these species) with those of species in the C. scalaris group, typically the fusion of sutural and subsutural stripes and also a tendency to fuse arcuate band with those too. Definitely worth keeping an eye on individuals with this appearance to try to figure out where they fit."
