Remarks and Distribution. This species mostly occurs in the upper Midwest, however scattered records are available from Pennsylvania west to Nebraska and Colorado south to Arkansas and Kentucky ( Nelson 2000, Zuellig et al. 2006). Mature larvae of this species can be separated from the closely related P. dorsata by the presence of a convex lateral bulge that does not exceed the level of the pronotal projections ( Figs. 40 View Fig , 41 View Fig , 44 View Fig ) and the approximate triangular shape of the rearward projecting process on sternum 9 of male larvae, the resulting angle=63.91 ± 13.16 ( Figs. 38 View Fig , 43 View Fig ).
