Adults may be distinguished by characters given in the key. The larvae of this species are known to complete their development in the flower clusters of paper birch (Betula papyrifero) within approximately 1 month of hatching and pupate within the clusters. Adults feed on the leaves of birch. Kissinger (1959) designated the lectotypes of A. walshii and A. uicinum. Map 24. Collection localitiee of Apion simile (l) and A. spuuliferurn (O).

Body slender, very dark reddish black; legs and antenna slighter lighter. Pubescence consisting of white, very fine, moderately long, sparse scales. Frons 1.0 (female) to 1.3 (male) times wider than dorsal tip of rostrum, with numerous, shallow, fine, longitudinal sulci. Rostrum of male moderately curved,I.2 times longer than pronotum; sides, in dorsal view, slightly converging in apical third, rather strongly expanded at antennal insertion, distinctly 136
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.
