Comments. This species belongs to the subgenus Eutrichapion
and is distinguished from other members of the subgenus by its reddish
yellow legs and by its northern distribution. This species and
A. qntennatum occur farther north than any other species of Apion in
Canada. The reddish legs distinguish adults of A. alaskq'numfromthose
of A. clntenne.tu.m, which has black legs. Adults were found in July on
Hedysarum alpinurn. Nothing more is known of its life history or habits.
