frontal costa in Neotettix, which, with the other characters we 

 have shown, will separate, with little difficulty, its members from 

 any of the others named. 



Key to Species of Neotettix. 



1. (2) Vertex in dorsal view with front border rounded, a little wider 



than one of the eyes . . . Sp. i. N. rotundafrons sp. n. 



2. (i) Vertex in dorsal view with the front border slightly convexed, 



much wider than one of the eyes. 



3. (4) Pronotum strongly rugose, scabrous; frontal costa scarcely pro- 



tuberant Sp. 2. N. bolteri sp. n. 



4. (3) Pronotum granulate or arenose; frontal costa rather strongly pro- 



tuberant Sp. 3. N. bolivari nov. nom. 



Position? Sp. 4. N. femoratus Scud. 



1. N. rotundafrons sp. nov. (Figs. 3, 3a, 3b, 3C, 3d, PI. VIII). Slightly 

 smaller than bolivari. Body granulate, or to a certain extent very little 

 rugose; vertex not as broad as in bolivari, barely wider than one of the 

 eyes, the front border rounded, crown inconspicuously mammillate poste- 

 riorly; frontal costa not so roundly protuberant, branches of fork about 

 as widely separated; pronotum truncate in front, posterior process ter- 

 minating acutely, reaching to or slightly overreaching apex of femora 

 when considering dimorphic forms together; median carina toward the 

 front slightly arched longitudinally, distinctly elevated; dorsulum trans- 

 versely tectiform, not broad between the shoulders, humeral angles ob- 

 tuse or sub-straight, lateral carina slightly present. Wings shortened, 

 not quite reaching to, or passing a little beyond the apex of process. 

 Elytra oval, rounded apically ; second femur with margins somewhat 

 undate, posterior femora broad, rather stout. Length entire 9 mm.; pro- 

 notum 7.5-8 mm.; post-femora 5.5 mm. 



Described from two females. Locality Jacksonville, Florida 

 (Bolter). In one specimen the body is reticulated with fuscous, 

 contrasting with yellowish white; dimorphism occurs in the wing- 

 lengths. This species probably nearest resembles T. femoratus 

 Scud. 



2. N. bolivari nov. nom. (Figs. 2, 2a, 2b, 2C, 2d, PI. VIII). Body granu- 

 late; vertex much broader than one of the eyes, crown mammillate on 

 each side posteriorly, front border slightly convex, rounding abruptly 

 into sides, mid-carina disappearing posteriorly on the crown a little beyond 

 the middle, in profile rounded, advanced but little in front of the eyes, 

 continued unbroken with the frontal costa; frontal costa produced, seen 

 n front strongly forked; pronotum truncate or scarcely angulate anteriorly, 

 advanced upon the head to the eyes, apical process acute, extended 

 backwards to posterior knee, dorsum rather sharply tectiform, median 

 carina distinctly raised, slightly arched longitudinally, humeral angles
