the entire back between the white lateral lines is claret red, and angulated 

 downwards on the sixth and ninth segments. 



A young specimen, found Sept. 10, 1841, had the whole back deep claret 

 red, bounded on each side by an irregular whitish line. The claret color 

 was angularly dihited on the sixth and ninth segments, and the tubercles on 

 the fourth and cleveuth segments were also deep claret red . Length three 

 fourths of an inch.
