Addendum 



The following species should appear on page 80, immediately preceding 

 Eurymerodesmus louisianae.

Polydesmus hispidipes Wood, 1864, Proc. Acad. Nat. Sci. Philadelphia, 

 p. 7; 1865, Trans. Amer. Philos. Soc, new ser., vol. 13, p. 220, fig. 48. 



Eurymerodesmus hispidipes Brolemann, 1900, Mem. Soc. Zool. France, 

 vol. 13, p. 101, pi. 6, fig. 32. — Causey, 1950, Ohio Journ. Sci., vol. 50,

Type : If extant, present location unknown. 



Type Locality: "Illinois."
