( Figs. 50–57 )

Remarks and Distribution. This species ranges from Quebec south along the Appalachians to West Virginia and Kentucky ( Nelson 2000). Larvae of this species are most similar to P. scotti but can be distinguished by the spines on the abdominal segments. In P. proteus , spines of AB 1-7 are well developed with the largest projections possessing a convex outer margin and appearing hook-shaped in dorsal view ( Figs. 51 , 54 , 57 ). When viewed laterally, the spines of AB5-7 are well defined, rugose, triangular shaped projections, the dorsal edge projecting caudally, parallel to the lateral surface of the segment ( Figs. 50, 53 ). Measured in dorsal view AB-4 POM/SW ≥ 0.15; AB-6 POM/SW> 0.12 (Care should be used in the use of these ratios due to marginal overlap in observed measurements with P. scotti ) ( Figs. 10 , 51 , 54 ). Live and recently preserved specimens also possesses a distinctive median yellow antennal band that is absent in P. scotti ( Figs. 56 , 57 ).
