119. Tettigonia redacta, sp.n. (Tab. XVIII. fig. 21.) 
T. quadrivittate affinis ; capite longo, producto, rotundato, testaceo, nigro antice et ad medium lineato, oculis 
vix prominulis ; pronoto distincte capite breviori, convexo, brunneo-testaceo, disco virescente; scutello 
testaceo, obscure nigro lineato; tegminibus apicem versus angustatis virescentibus, vittis duabus latis rufis ; 
abdomine supra rufo-flavo ; corpore subtus et pedibus flavis. 
Head large, considerably produced, rounded, testaceous, with a black line encircling the vertex, and another 
just inside this including a testaceous space; there are also two fine lines on the centre of the disc 
proceeding from the apex of the latter to the base of the head; eyes not very prominent; pronotum 
convex and shining, distinctly shorter than the head, testaceous, with the centre of the disc, and the base 
narrowly, greenish ; scutellum large, with obscure dark lines; tegmina green, with two broad crimson 
bands—one on the clavus, the other on the corium, the margins light ; abdomen orange above; underside 
and legs yellow. 
Long. 6 millim.; lat. vix 2 millim. 
Hab. Panama, Pefia Blanca (Champion). 
This insect may possibly be a variety of 7. guadrivittata, but it differs from the 
examples which I have seen of that species in having the head less triangular, more 
rounded, and figured as above described, and the pronotum comparatively shorter, as 
well as in having two crimson bands only on each tegmen. In 7. quadrivittata the 
head is distinctly more triangular, of a clear testaceous colour, or suffused with red, 
with a broad black line along the vertex. 
120. Tettigonia idonea, sp.n. (Tab. XVIII. fig. 22.) 
Obscure rufo-castanea; capite plus minusve producto, obtuse rotundato-angulato, oculis prominulis, limbo 
testaceo, nigro antice marginato; fronte flavo-testaceé; pronoto convexo, limbo anteriori et laterali 
albido-testaceo, margine posteriori et vitté sat lata longitudinali ante marginem anteriorem interrupta 
virescenti ; scutello fusco-rufo, unicolori; tegminibus apicem versus angustatis, margine exteriori anguste 
testaceo, sutura pone scutellum et duabus vittis virescentibus, apice haud hyalino; corpore subtus testaceo ; 
pedibus testaceis, plus minusve fusco suffusis. 
A moderate-sized species, of a dark velvety reddish-chestnut-colour; head more or less produced, obtusely 
rounded in front, with the eyes rather prominent; round the front and sides runs a sharply-defined 
testaceous border, bounded before the testaceous forehead by a black line; pronotum convex and 
shining, with the front border and sides testaceous, and the posterior margin and a longitudinal central 
band, ceasing before the apical border, green ; scutellum fuscous-red ; tegmina gradually and considerably 
narrowed to the apex, with the exterior margin testaceous, and a line surrounding the scutellum and 
continued along the suture to about the middle, and two other lines (one extending along the claval
