This Nearctic species has previously been recorded in Alberta, British Columbia, Colorado, Connecticut, Idaho, Indiana, Iowa, Maine, Manitoba, Massachusetts, New Hampshire, New York, Ontario, Oregon, Québec, Rhode Island, Washington, and Wisconsin (Blatchley 1910; Britton 1920; Leng 1920; Procter 1946; Hatch 1961; Oatman et al. 1964; Bousquet 1991; Downie and Arnett 1996; Schwert 1996; Chandler 2001; Jacobs et al. 2006; Sikes 2004). It has been reported on fungi and molds in litter and nests (LaBonte 1998). In Atlantic Canada it has been found in mixed forests, coniferous forests, along forest roads, in raised bogs, salt marshes, and pastures. Jacobs et al. (2006) and Hammond et al. (2001) both reported this species as a member of saproxylic beetle assemblages on <i>Populus tremuloides</i> Michx (Salicaceae) in Alberta. <b>Description:</b> Head piceous; finely sparsely punctate. Pronotum piceous; distinctly widest at midpoint, narrowing to base and apex; flattened across basal margin; finely sparsely punctate, interspaces between punctures ̴ 2.0 times the diameter of punctures. Scutellum piceous. Elytra testaceus, slightly darker along suture, with a pominent piceous crossbar at approximately the 2/5 point of the elytra, slightly curved posterad and frequently extending across the suture; punctures slightly coarser and slightly denser than on pronotum; interspaces between punctures ̴ 1.5 times the diameter of puctures; elytral setae slightly longer than interspace distance and appressed (Fig. 4). Antennae: antenomere 1 swollen, wider and longer than 2; 3 almost the same length as 2; 4, 6, and 8 short and of similar length; 5 and 7 somewhat longer; antennal club somehwat indistinct and not clearly demarcated, antennomere 9 only slightly wider than 8; 9 and 10 quadrate, not transverse (Fig. 1.3). Body: width/length ratio, 0.46; length, 1.5–1.6 mm.
