Remarks and Distribution. Previous descriptions of the larva of this species are adequate. The first description was provided by Smith (1917). Claassen (1931) later provided a more detailed description. This species can be reliably separated from other members of the genus based on the presence of the conspicuous abdominal projections on abdominal segments 1-8 ( Figs. 13, 14 View Fig ), the lack of a prominent acute lateral projection on the mesothorax ( Fig. 15 View Fig ), and the acute angle (APP> 55) of the anterior pronotal projection ( Figs. 15 View Fig , 17 View Fig ). The distribution of this species extends from Canadian Maritime Provinces south to Alabama ( Nelson 2000).
