TETTIGONIA. 257 
58. Tettigonia bilineata, sp.n. (Tab. XVI. fig. 27.) 
Aurea, levis, nitida, capite fere semicirculari, macula nigra inter ocellos nigros rotundata vel cordiformi, oculis 
nigris vix prominulis ; pronoto antive angustato, basi fere recté; scutello magno, concolori; tegminibus 
vitté angusté nigra curvata, scutellum attingente, et alid pone medium latiori instructis ; abdomine flavo- 
rufo; pedibus dilute testaceis. 
Golden-yellow, smooth, and shining, with the ocelli and a rather large round or heart-shaped spot between 
them, the eyes, which are scarcely prominent, and two bands on each tegmen, black; of the latter, 
the front ones reach the scutellum and extend in a curve to the costal margin, along which they are 
continued to near the middle of the tegmina; the hinder ones meet at the suture and form a straight, 
but more or less irregular band across the upper surface behind the middle; head rounded, nearly 
semicircular; pronotum narrowed in front; abdomen above orange-coloured ; underside and legs light 
testaceous or rufo-testaceous. 
Long. 10 millim. ; lat. ad hum. 23 millim. 
Hab. Mexico, Amula, Venta de Peregrino, Acaguizotla, and Rincon, all in Guerrero 
(H. H, Smith). 
We figure a specimen from Amula. 
59. Tettigonia teniata, sp.n. (Tab. XVI. fig. 28.) 
Aurea, nitida, levis, vittis duabus latis cyaneo-nigris ; capite lato, quadratim rotundato, vel fere semicirculari ; 
ocellis et oculis nigris, his nonnihil prominentibus ; corpore subtus pedibusque rufo-flavis ; apice abdominis 
late, femoribus anticis superne cum tarsis, unguibusque intermediis et posticis nigris. 
Of a bright golden colour, smooth, and shining, with two broad velvety cyaneous-black bands extending across 
the upper surface, the front one including the base of the pronotum, the scutellum, and the basal part 
of the tegmina, and the hinder one just before the apex, which is yellow; the apex of the abdomen is 
broadly black, and the upper surface of the front tibia, the front tarsi, and the intermediate and posterior 
claws are black. 
Long. 11 millim.; lat. ad hum. 3 millim. 
Hab. Panama, Bugaba (Champion). 
60. Tettigonia distinguenda, sp.n. (Lab. XVI. fig. 29.) 
Precedenti affinis, sed capite ad basim pronotoque ad apicem cyaneo-nigris, hoc parte basali flavescenti et 
tegminibus vitté laté ad basim scutellum includente nigra, alterdque apicem fere attingenti macula 
flava triangulari profunde indentata instructis, distinguenda. 
Very like the preceding, of which it may possibly be a variety, but easily distinguished by the base of the 
head and front of the pronotum being black, as well as by the basal part of pronotum being yellow, and 
the apical band on the tegmina nearly reaching the apex, and being almost divided by a triangular yellow 
patch, the base of which rests on the margin. 
Long. 11 millim.; lat. ad hum. 3 millim. 
Hab. Panama (Boucard). 
61. Tettigonia ostrina, sp.n. (Tab. XVI. fig. 30.)

producto obtuse rotundato, oculis prominulis, hoc convexo, levi, antice angustato, basi leviter late sinuata ; 
tegminibus levibus sat nitidis, margine obscuriori, apice abrupte hyalino ; abdomine supra rufo; corpore 
subtus pedibusque testaceis.
