ATAXIA (to follow the genus Parysatis, p. 113). 
Ataxia, Haldeman, Trans. Amer. Phil. Soc. x. p. 56 (1847); Lacordaire, Gen. Col. ix. p. 599. 
Stenosoma, Leconte, Journ. Ac. Phil. ser. 2, ii. p. 158 (1852) (nec Mulsant). 
There is little to distinguish the following genus, Esthlogena, from Ataxia; the only 
structural character which I can perceive is the sharp and rather elevated outer apical 
edge of the scape which distinguishes Ataxia, and in which it resembles Parysatis, 
differing in being unaccompanied by a narrow cicatrice. 
One North-American species only has yet been described.

Said by Erichson to be the Saperda lineata of Fabricius (Ent. Syst. ii. p. 314), and 
so registered in the Munich catalogue, but it does not agree with the description, 
which refers also, as Fabricius states, to a South-American (Brazilian?) insect in Lund’s 
collection.
