TETTIGONIA. 287 
147. Tettigonia pileata, sp. n. (Tab. XIX. fig. 18.) 
Parva, sat angusta et parallela, olivacea, limbo lato verticis, lateribus pronoti, scutello, sutura clavali late, et 
suturé ips’ ab apice hujus usque ad apicem tegminum lete flavo-miniatis; capite triangulari, obtuse 
rotundato, oculis vix prominulis, intra limbum testaceo, ohscure figurato; pronoto sat longo, antice dilutiori ; 
abdomine supra fusco ; alis fumosis ; corpore subtus dilute testaceo ; pedibus albidis. 
A small and rather narrow species, very brilliantly coloured, olivaceous, with a broad border round the vertex, 
the sides of the pronotum, the scutellum (which is comparatively small), and the claval suture, bright 
scarlet-orange, this colour extending along the suture from the apex of the clavus to the apex of the 
tegmina ; head obtusely rounded, light green inside the orange border and more or less obscurely figured ; 
pronotum lighter green in front and at the sides; tegmina subhyaline just at the apex; upperside of the 
abdomen fuscous, underside light green ; legs very pale, with the claws fuscous. 
Long. 6-7 millim.; lat. 13 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
In coloration this insect closely resembles the species of the 7. aurolineata-group, but 
in the shape of the head it is more nearly allied to 7. orbata. 
Several examples were obtained. 
148. Tettigonia concinnula, sp.n. (7. compta, Tab. XIX. fig. 19.) 
Parva, capite triangulari, acute producto, miniato, plus minusve obscure fusco-variegato; fronte plerumque 
nigré, oculis nigris vix prominulis; pronoto convexo, antice angustato, fusco, margine anteriori late 
miniato; scutello miniato, concolori; tegminibus fusco-testaceis, vittaé miniaté ad suturam clavalem, ad 
medium macula nigra longitudinali interrupta, et ad apicem suture clavalis macula alia nigré parvad 
instructa; alis fumosis, truncatis; abdomine supra miniato vel puniceo; corpore subtus pedibusque 
testaceis, plus minusve fusco- vel rufo-variegatis. 
A small, shuttle-shaped species, with the head sharply triangular, scarlet, almost unicolorous or more or less 
obscurely variegated with black; forehead black, with a few scarlet markings and a round spot just 
before the vertex; pronotum convex, narrowed in front, fuscous, with the anterior margin broadly scarlet ; 
scutellum scarlet, unicolorous; tegmina fusco-testaceous, with a rather narrow scarlet double band 
running along the claval suture and continued in a single line from the apex of the clavus to the apex of 
the tegmina, the continuation being sometimes absent ; at the middle and apex of the outer part of the 
band are two small black longitudinal patches, the one at the middle being very conspicuous ; abdomen 
crimson or scarlet above; underside and legs testaceous, more or less variegated with fuscous, base of the 
femora dark, posterior tibie scarlet towards the base, fuscous towards apex. 
Long. 5 millim. ; lat. 13 millim. 
Hab. Mextco, Omilteme in Guerrero 8000 feet (H. H. Smith). 
149. Tettigonia teres, sp.n. (Tab. XIX. fig. 20.) 
Parva, capite triangulari, haud acute producto, oculis magnis; fronte fere toté nigra; vertice, pronoto et 
scutello dilute rufo-testaceis, colore obscuriori figuratis ; pronoto capite distincte longiori, antice angustato ; 
tegminibus rufo-brunneis, obscure et minute albido-irroratis, macula ad humeros flavé, communique macula 
hyalina ad medium ; alis fumosis; abdomine supra rufo, subtus testaceo; sterno ad partem nigro ; pedibus 
testaceis, femoribus ad basim late nigris. 
A small species, with the front-parts light reddish-brown, figured with a darker shade; head triangular, 
produced, but not acute as in 7. concinnula; pronotum distinctly longer than the head, narrowed in front ; 
tegmina of a reddish-brown colour, with minute light spots and a common irregular hyaline spot at the 
middle bounded by a line of darker colour, the apex, except a very small portion internally, not hyaline ; 
on each shoulder there is a waxy-yellow patch ; wings smoky, truncate, but less so than in the preceding
