The lamellae also show some marked differences, such as the presence of a high basal, the shorter columella not reaching the base, but with relatively larger horizontal part, the bifurcation of the parietal and the presence of a supra-palatal, the last just as it is in P. armifera. It must be added here that the specimen first obtained from Minnesota in several respects differs from those found in Illinois and Iowa, which I consider as typical; by its size which is one third smaller, by the basal lamella developed in a peculiar way, being rather longer at the truncated top than at its foot, and by the stronger, thicker palatal lamellae. Yet, as there was only one specimen, it was liable to be an individ- ual peculiarity, — even then of interest. Should, however, more specimens be found with the same configuration, they would represent a distinct and well characterized variety ; Pupa Hoizingeri possibly it is a peculiar northern form, enlarged. New Philadelphia, Ohio, June, 1889. The above is a description by Dr. V. Sterki1 of a Pupa received by him from Winona, Minn., and Northern Illinois. He kindly furnished me the above figure.
