Lancaster, N. Y., August (Van Dusee). A species of north- 

 ern distribution, its range extending from Ontario and New 

 England west to British Columbia. Except in the longer first 

 antennal the description of N. alter nut us Parshley (1922, 12) 

 agrees very closely with inscriptus.

Marion Co., Ind., July 22 — Oct. 14 ; swept from rank weeds 

 along the borders of streams. Known heretofore only from 

 Wisconsin, Missouri, Nebraska and Colorado. "Rather similar 

 to A", fcrus L., but the color more inclined toward a pale yellow, 

 the apex of dorsum widely testaceous and the intervals of 

 elytra devoid of fuscous punctures" (Renter).
