 produced over the occiput, posteriorly abbreviated obtuse or 

 acute, not reaching apex of posterior femora; dorsum before 

 the shoulders arcuate, transversely acute tectiform, between 

 and behind the shoulders subdepressed; superior elytral sinus 

 of lateral lobes shallow. Wings abortive; elytra small sub- 

 rounded at the ape.^:. Posterior femora moderately stout.

Tettix polymorpha, Burm., Haub. Ent., ii., 659 (1838); 

 Tettigidea polymorpha, Scudd., Bost. Jour. Nat. Hist., vii, 

 447, 448 (1862). 



The bibliography of this species as well as some of the 

 others of this group is exceedingly confusing as several forms 

 are referred to under one species. The typical form is 

 undoubtedly from South Carolina. The above description 

 applies to the form found in Florida, and it is not certain but 

 that it is distinct. 



Scudder, Index N. Am. Orth., 315, 316 (1901). 



Morse's studies. Jour. N. Y. Ent. Soc, iii, 108, 109 

 (1895), brought forward certain evidence to show that Tetti- 

 gidea lateralis of Say is confined to the southern states, 

 the species inhabiting the northeastern states being par- 

 vipeniiis and its congenor peniiata. My studies of consider- 

 able material confirms this view, but in addition there appears 

 to be an intermediate form of Tettigidea from southern Illinois,
