expanded toward apex; basal two-thirds coarsely alutaceous, with
moderately d"ep, .o-u*hat elongate punctures; tip smoother
with "our.", finer punctures. Rostrum of female strongly curved, 1.6 times
longer thalpronotum; otherwise similar to male. Antennae inserted in
basal o.z (male) or 0.17 (female) of rostrum. Eyes slightly convex.
Pronotum at base 0.9-1.0 times wider than long; sides nearly parallel
near base, slightly expanded toward middle, arcuate to anterior margin;
disc moderately cbnvex, flattened anteriorly and basally, with very deep,
close punctures bearing fine scales; interpuncture spaces finely
alutaceous, much narrower than diameter of punctures. Elytra 1.6-1.8
times longer than wide; striae moderately wide and deep; interstriae
nearly flat, about twice as wide as striae on disc, with 1 or 2 rows of fine
punciures bearing fine scales, these usually distinctly longer than those
bn dorsal surface of pronotum. Femora of male forelegs strongly swollen
near distal third; polished area on ventral surface extremely finely and
densely striate, without limiting carina. Tibiae of male middle and hind
legs mucronate.
Distribution. Known only from Manitoba to Alberta' Not
known in the united states. Alberta: Medicine Hat. Manitoba: Aweme.
Saskatchewan: Pike Lake.
Comments. This species is a member of the subgenus Fallapion'
It is distinguished by the greatly swollen front femur of the male and by
the lack of a limiting carina near the polished area on the ventral surface
of the front femur of the male. Nothing is known of its life history or
habits.
