For the Nearctic Region, pupal cases of only 2 species in 2 genera have been described. The pupal case of Apachekolos tenuipes (Loew) is described herein for the first time. Leptogaster flavipes Loew was described briefly in Malloch (1917) and Bromley (1946) . The following tentative key is based on information presented in the aforementioned publications, as well as Melin (1923) , Séguy (1927) , and Zinov'eva (1959) concerning Leptogaster species not found in the Nearctic Region.
