These are good photos.

Do you have pictures showing the joints in the front leg (I can't see where the first two segments of the tarsus end) and an extreme closeup of the wing surface showing hairs on the wing veins? Those may be useful once I acquire a key that follows modern classification. Based on the 50+ year old key to Northeastern species I have this appears to be in Tanytarsus in the modern sense (it was called something else at the time).
