Description. Length I.4-1.9 mm. Body moderately slender,
black; elytra with faint brassy or metallic luster; antennae with paler
bases. Pubescence consisting of white, moderately coarse, moderately
sparse scales, these slightly denser on sides of metathorax and
metepisternum. Frons 0.9-1.1 (male) or 1.0-1.2 (female) times wider
than dorsal tip of rostrum. Rostrum of male moderately curved, LI-L.2
times longer than pronotum; sides, in dorsal view, slightly expanded
toward apex; surface with moderately coarse, sparse punctures,
becoming finer toward apex; scales very sparse below antennal
insertion, mostly confined to region near eye. Rostrum of female slightly
curved in apical quarter, 2.0-2.3 times longer than pronotum; sides, in
dorsal vieq not expanded at antennal insertion, slightly expanded at
apex; surface largely polished distal to antennal insertions; lateral areas
with moderately coarse, dense, elongate punctures, becoming frner and
sparser toward apex; base with sparse, small scales, mostly near
anterior margin of eye. Antennae inserted between basal 0.3-0.4 (male)
or aL 0 .2 (female) of rostrum. Eye slightly convex. Pronotum at base 1. 1
times wider than long, without basal flange; sides slightly diverging to
widest point near basal third, rounding to very slightly constricted apex;
disc slightly convex, with moderately coarse scales and moderately deep
punctures; interpuncture spaces much narrower than diameter of
punctures and finely alutaceous. Elytra 1.2-L4 times longer than wide;
striae moderately deep, with fine punctures; interstriae nearly flat,
about three times wider than striae, each interstria with I or 2 partly
confused rows of fine punctures and with scales similar to those on
dorsal surface of pronotum; interstriae 7 and 9 each with 1 long
specialized seta. Male legs lacking special characters.
Distribution. Manitoba to Alberta, south through the western
United States to Baja California, Mexico, east to Illinois. Alberta:
