Thanks John, sounds like this must be curvicauda.

Should be curvicauda
Of the two North American species of Coenia treated by Mathis (1975), only curvicauda should be found in Massachusetts. The other species, alpina is arctic and alpine. Otherwise they are reliably distinguished by male sexual characters not visible from this angle (and this might not be a male).

Coenia
Note the bristly face, typical for the subfamily. There are four bristles in each of the rows of strong bristles on the top of the thorax (they are called dorsocentrals). Similar genera have five.
