So the previous was an angle wing katydid of some form, this one is one of the bush katydids (Scudderia sp.), but I didn't get a photo that will narrow it down enough. Bug Guide tells me that it's important to see the "terminalia" for species identification here. 9/12/2015, Concord MA.

I'd biked all the way to Great Meadows NWR in Concord, after setting out along the Minuteman without a destination clearly in mind.
