Malar space wanting; antennae distant from the clypeal border by a little less than the length of the pedicel; scape with erect hair beneath, dense in the males; pronotum with a long dorsal surface, rounding rather abruptly into a pronounced but not deep vertical surface, and with a short horizontal collar, all this much in Calicurgus, but less abrupt; upper surface of hind tibiae not carinate, but with minute elevations at the bases of spines which scarcely exceed the length of the tibial hair, and are absent at the base of the tibiae; head, thorax, propodeum, coxae and abdomen of the males more hairy than in the species of Priocnemis.

In the following list of additions and corrections to my “Annotated Check List of the Macrolepidoptera of Alberta”, published in 1919 by the Alberta Natural History Society, the numbers and names are in accordance with the McDunnough list of 1938, the numbers of the Barnes and McDunnough list of 1917 being given in brackets. Since 1921, seven brief lists of additions and corrections have appeared in the Canadian Entomologist (53: 13-14, 211-212, 55:71-72, 56: 189-191, 60: 117-118, 66: 131-132, 70:260-261).
