( Figs. 24–27 )

Remarks and Distribution. This is the most infrequently encountered member of this genus. Scattered records are available from New Brunswick, Maine, New York, Pennsylvania, Virginia, West Virginia, and Kentucky ( Nelson 2000). Larvae of P. comstocki are easily separated based on the well-developed curved abdominal projections on AB1-8 ( Fig. 25 ), pointed, semi-lunate supra-antennal process ( Fig. 26 ), acute, well developed pronotal projections, and the presence of a sharply pointed process on the mesothorax ( Fig. 24 , Fig. 27 ).
