In the course of my studies in this interesting genus I have gradually accumulated a few specimens of a species which on genitalic characters (both ♂ and ♀ ) is abundantly distinct from any of our other eastern species. As these genitalic characters of practically all the described species are known to me, due to a study of type material, I believe the present species to be undescribed and offer the following description.
