Siphlonurus
Hi Tom-

Am (at least temporarily) moving these images back to genus level placement due to their lacking a single brown cloud in their forewing. Please see https://bugguide.net/node/view/2333564.

Moved from Siphlonurus.

Siphlonurus typicus
I believe. Described from Worcester Mass and the larvae are common in New England, but the male genitalia has never been figured to the best of my knowledge.
