Type locality: southeastern Pennsylvania (Haldeman 1843a: 297). One possible syntype, a ♂ labeled "[pink disc] / elongatulum Hald. [handwritten] / picipennis 4 [handwritten]," in MCZ (Lindroth 1966: 581). Agonum canadense Goulet, 1969: 279. Type locality: "Bala, N[orth]W[est] Gravenhurst, Ontario" (original citation). Holotype (♂) in CNC [# 11574]. New synonymy . Note. The specimen probably belonging to Agonum elongatulum Haldeman in LeConte's collection is conspecific with specimens of Agonum canadense Goulet. Goulet's name is retained as valid since Haldeman's name is a junior homonym of Agonum elongatulum (Dejean). Distribution. This species is found from Cape Breton Island (Bousquet 1987d: 106) to southern Manitoba (Goulet 1969: 280), south to east-central South Dakota (Larsen and Purrington 2010: 570), northern Illinois (Goulet 1969: 280), and northern West Virginia (Tucker and Preston Counties, CMNH). The record from "Nebraska" (Bousquet and Larochelle 1993: 253) needs confirmation. Records. CAN : MB, NB, NS (CBI), ON, PE, QC USA : CT, IL, IN, MA, ME, MI, NH, NJ, NY, PA, SD, VT, WI, WV [NE]
