Steuben County; rare. June 17. Taken by sweeping herbage 

 in tamarack swamp. Occurs on the willow, tialix longifolia. A 

 European species introduced by commerce. Of it Knab writes me: 

 "Generally passes in collections as P. vulgatissima L., but Weise 

 states that the latter species has the thorax finely margined behind. 

 I have seen no American specimens with this character."
