Distribution; BC‒CA to w.MT‒UT

Information: fields, gardens, parks, sand/gravel pits, moraines, meadows, roadsides, forest clearings, usually on more or less dry sandy soils.(ref.)

Description: body: elongate-ovate, moderately robust; moderately convex. Dorsal and ventral colouration should be very similar; semi-glossy to matte bronze or bluish-black. Head: rather broad, triangular. Eyes very small, weakly bulging laterally; eyes angled forward slightly. Two long supraorbital setae over each eye. The surface of the head is mostly smooth, with two semi-circular dimples on the frons, which do not continue onto the clypeus. Labrum somewhat large, rectangular, with opaque yellow margins, which are uniform within this species. Mandibles matte black or greyish, curved; relatively short, lateral outer margin of each mandible often orange. Antennae do not span fully to the hind angle of the pronotum; the first three antennal segments (scapus, pedicel, and the first following antennomere) orange, which the rest of the antennae is dark. Antennal pubescence begins on the second antennomere following the pedicel (segment 4). Pronotum domed; front margin curved slightly inward; front angles weakly obtuse, pointed forward; lateral margins sloped toward the head; hind angles squared; basal margin weakly sinuous. Pronotal margins fully beaded. Median line weak, but typically visible, dorsum very weakly wrinkled, otherwise smooth; dorsal hind angles may appear duller or somewhat matte in some individuals. The base of the pronotum should be as wide as the elytral shoulders. 7-8 thin, but well-defined striae per elytron, intervals flat. Elytral microsculpture circular, creating a sort of net-like mesh appearance. Scutellum exposed, no parascutellar pores should be present on this species. This species also should not have any setae, fovea, nor pubescence on the striae or the strial intervals aside from the lateral margin setae found on most carabids. Humeral shoulders should be fully obscured by the pronotum, but are squared; lateral margins straight, or weakly curved; apices weakly sinuate. Legs glossy black.
