SUBFAMILY I. TETRIGINJE. 171 



alls Say and Anaxlplm pulicaria (Burm.), the latter not being 

 found elsewhere on the mainland about Dunedin. 



Scudder (1877a, 90) recorded Tettix arenosus from Ft. Keed, 

 Fla., and stated that "it is closely allied to T. rugosa Scudd., but 

 the wings scarcely surpass the pronotum, a feature which appears 

 to be constant." Since this character is true of .4. a. blatchleyi 

 and not of A. a. arcnoaum, his specimens were probably of the 

 former race. 



III. NEOTETTIX Hancock, 1898, 138. (Gr., "new" + Tettix.) 



Short, rather stout species having the body granulate or ru- 

 gose; vertex wider than one of the eyes, its front margin convex 

 or rounded, viewed from the side slightly advanced in front of 

 eyes (Fig. 62a) ; frontal costa convex, not sinuate between the 

 eyes, its branches, viewed in front, strongly divergent or forked; 

 antennae rather stout, short, composed of 12,, rarely 13, segments; 

 pronotum with its front dorsal margin advanced over 'the head to 

 the eyes, posterior process acute and usually not or barely reach- 

 ing tips of hind femora, surpassing them in the long forms; its 

 dorsal surface more or less tectate between the shoulders, median 

 carina distinct, usually more elevated between and in front of 

 shoulders ; tegniina elongate-elliptical, sometimes very minute, 

 their tips rounded or subacuminate ; wings either aborted or fully 

 developed and slightly passing the apex of pronotum; hind fem- 

 ora rather short; hind tarsi with first segment distinctly longer 

 than second and third united, the pulvilli acute but more or less 

 flat below. Ten species have been described from North Amer- 

 ica, but E. & H. (1910, 135) have shown that six of them are sy- 

 nonyms. The three found in our territory are separated as 

 follows : 



KEY TO EASTERN SPECIES OF NEOTETTIX. 



a. Hind margin of lateral lobes of pronotum bisinuate; tegmina always 

 well developed and exposed; pronotum with front dorsal margin 

 truncate and median carina not strongly compressed, elevated and 

 curved. 



b. Pronotum with dorsal surface finely granulose, sometimes feebly 

 tuberculate, its hind process in short forms narrowly acute at 

 tip; ridges on outer face of hind femora not prominent. 



70. FEMORATUS. 



6&. Pronotum with dorsal surface distinctly rugose-tuberculate, usu- 

 ally strongly so between the shoulders, the short ridges usually 

 paired and regular, more prominent in the female; hind pro- 

 cess of pronotum in short form much stouter and obtusely
