— . Vertex not more than one and one-half times as long on the middle as 

 next the eye, sometimes of nearly eqnal length across its whole width; 

 elytral venation normal, the outer antiapical areole nearly or quite as 

 wide at apex as at hase, the post-nodal without recurved veinlets (C). 



C. Vertex sloping, either flat or convex, transversely impressed on the disc; 



form broad and stout, usually distinctly narrowed posteriorly; front 

 broad, pronotum usually transversely wrinkled and the elytral nervures 



strong (D). 



— . Form narrower and more elongated; vertex usually short and convex, 

 rarely with a transverse discal impression, in this case the front is nar- 

 row and the form slender (E). 



D. Elytra mostly reticulated with ramose, fine brown, pigment lines. 



Phlepsius. 



— . Elytra without ramose brown pigment lines, or with but few on a median 



fulvous band Eiitettix. 



E. Vertex short, scarcely longer on the middle than next the eye, the ante- 



rior edge strongly rounded, front broad (F^ 



— . Vertex longer on the middle, or even angled, the anterior edge less broadly 

 rounded or subacute, front narrow, sides of the pronotum cariuated. 



Tlianinotettix. 



F. Smaller and more slender insects. Pronotum considerably longer on the 



middle than at the shoulders, hind angles broadly rounded, sides very 

 short, terete; ocelli rather distant from the eyes Liiiiotetf ix. 



— . Larger and stouter insects. Pronotum scarcely longer at the middle than 

 at the shoulders, anterior edge quite strongly arcuated, hind angles 

 prominent, sides long and carinated, ocelli placed very near the eyes: 

 colors usually pale, green or greenish, with thin elytra and slender ner- 

 vures ; disc of the pronotum transversely wrinkled.. ..C"liIorofetlix. 



Tribe JASSINI. 



Anterior feet normal, the tibise not dilated Jassii!^. 



Anterior tibiie dilated, femora normal Tertilia. 



(In Petalopoda Spangb., from South America, the anterior femora also are 

 dilated, the tibise widely so, almost foliaceous). 



Tribe CICADULINI. 



First two sectors of the wings coalescing before the apex, the resulting nervure 

 uniting with the costa some distance before the tip of the wing, thus 

 forming but two apical areoles Giiatlio<luN. 



First two sectors of the wings united for a greater or less distance, but soon 

 again separating and attaining the apex of the vying, thus forming three 

 apical areoles I'icadiila. 



A generic synopsis of the Bythoscopidse may be found in " Ento- 

 niologica Americana," vol. v, p. 125, and a similar one at page 160 

 of the same volume. In Stal's " Heraiptera Fabriciana," ii, p. GO, 

 is a synopsis of the genera of the Tettigonina or the Proconina, as 

 he terms this group; and of the Typhlocybina Mr. Woodworth 

 has published a synopsis in " Entomologica Americana," vol. v, p. 

 214.
