TETTIGONIA. 279 
It is possible that this insect may be a variety of the preceding, but as it comes from 
an entirely different locality I am inclined to regard it as distinct. 
126. Tettigonia limbaticollis. (Tab. XVIII. fig. 27.) 
Tettigonia limbaticollis, Stal; Stett. ent. Zeit. xxv. p. 75 (1864) *. 
Hab. Mzxico (coll. Signoret}), Teapa in Tabasco (H. H. Smith). 
This species is allied to 7. urbana, from which it may be known by the greener 
colour, the more distinct figuration of the front-border of the pronotum, and the narrow 
black line bounding the yellow margins of the latter; from 7. obtusior it may be 
separated by the more elongate head, as well as by the presence of the black lateral 
line on the pronotum, which appears to be a constant character, and to be wanting 
in the allied forms. 
127. Tettigonia anceps, sp.n. (Tab. XVIII. fig. 28.) 
Precedentibus affinis, viridis vel olivaceo-viridis ; capite elongato, triangulari, testaceo nigro-lineato ; fronte 
testacea, unicolori vel nigro-dimidiataé; pronoto nitido, levi, antice et ad latera late testaceo; scutello 
testaceo, unicolori ; tegminibus apicem versus angustatis, suturaé anguste flava; abdomine supra rufo ad 
partem infuscato; corpore subtus pedibusque testaceis. 
Allied to the three preceding species, from which it may easily be known by the unicolorous scutellum and 
the less close variegation of the head; it is further distinguished from 7’. limbaticollis by the absence of 
the black lateral line on the pronotum, and from 7. obtusior by the much more elongate head. 
Long. 7-9 millim.; lat. vix 2 millim. 
Hab. Panama, Bugaba (Champion). 
A considerable and very constant series has been received. It is possible that this 
and the three preceding insects may by future writers be regarded as belonging to 
one variable species, but at present it seems better to separate them. 
128. Tettigonia occatoria. (Tab. XVIII. fig. 29.) 
Tettigonia occatoria, Say, Journ. Acad. Phil. vi. p. 311 (1831)*; Sign. Ann. Soc. Ent. Fr. 1854, 
p. 353, t. 12. fig. 2°; Stal, Stett. ent. Zeit. xxv. pp. 75, 466°. 
Hab. Norta America, United States1*W—Mexico%, Ciudad in Durango 8100 feet 
(Forrer), Amula, Chilpancingo, Xucumanatlan, La Venta, Dos Arroyos, Tierra Colorada, 
and Tepetlapa in Guerrero, Vera Cruz, Atoyac, Teapa, and Frontera (H. ZH. Smith), 
Orizaba (f. D. Godman & H. H. Smith); GuatemMata, Cerro Zunil (Champion); 
PanaMA, Bugaba, David, and Volcan de Chiriqui (Champion). 
Signoret ? describes this species as yellow, with black lines, whereas in nearly every 
example contained in our large series the colour of the upper surface is for the most 
part dark green, with the head, the front of the pronotum, and the scutellum yellow. 
Some of our light-coloured examples, however, nearly agree with his figure. 
As there is some doubt about the identification of 7. occatoria, a description of our 
insect is added :—
