and tegmina are entirely testaceous, with the exception of a black spot on the front of 
the vertex: Signoret at first treated it as a variety of the preceding, but afterwards 
separated it. Iam inclined to think that 7. uniguttata is a colourless or immature 
variety of the preceding species. 
51. Tettigonia prestantior, sp.n. (Tab. XVI. fig. 20.) 
Major, postice latior, capite producto, nigro, subexcavato, oculis sat elongatis; pronoto antice nigro postice lete 
flavescenti, leviter rugoso; scutello nigro; tegminibus levibus, haud nitidis, basi et apice vittaque pone 
medium nigris, spatio intra vittam basalem et intermediam lete flavo, spatio post hanc flavo-rufo; corpore 
subtus plerumque testaceo ; pedibus testaceis ad partem piceis. 
A large, brightly-coloured species, with strongly contrasted black, yellow, and orange bands, the former having 
a cyaneous reflection in certain lights; head long, produced in an isosceles triangle, with the sides slightly 
rounded and bluntly angled at the apex, entirely black, except for a small portion of the metopidium above 
the rostrum—if viewed from the side, subexcavate, sharply pointed, and slightly deflexed ; pronotum 
bright yellow, with the front part abruptly black, finely rugose ; scutellum large, black; tegmina dull, 
smooth, with a black band at the base (forming with the scutellum, which it includes, a broad black band 
right across the body of the insect) ; a long yellow space behind this, and a broad black band just behind 
the middle, followed by a bright orange space before the apex, which is black ; underside mostly testaceous, 
fuscous towards the apex of the abdomen; legs testaceous, more or less pitchy. 
Long. 14-15 millim.; lat. ad hum. 33 millim. 
Hab. Panama, Bugaba (Champion). 
A considerable series. ‘This is one of the most gaudily coloured and conspicuous 
insects of the whole group; it appears to be extremely local. 
52. Tettigonia undecimmaculata, sp.n. (Tab. XVI. fig. 21.) 
Quoad staturam precedenti affinis, sed capite breviori, oculis magis prominulis; testacea, capite nigro- 
notato, pronoto maculis tribus testaceis; tegminibus levibus, sat nitidis, maculis octo conspicuis, duabus 
ad basim, quatuor ad medium, duabusque ante apicem instructis; corpore subtus pedibusque dilute 
testaceis. 
Upperside fusco-testaceous, with black markings on the head and three light testaceous spots on the pronotum ; 
head triangular, depressed, with the sides towards the front raised in a ridge on each side; tegmina 
smooth and rather shining, with two large round testaceous spots at the base, four in a line just behind 
the middle, the two inner ones being smaller and not rounded, and two large and conspicuous round spots 
at the apex; underside and legs light testaceous. 
Long. 18 millim.; lat. ad hum. 3 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
The specimen on which I have described this species appears to be somewhat 
immature, and the colour is probably darker as a rule, but the eight large and 
conspicuous spots on the tegmina render the insect so easily recognizable that I have 
thought it best not to pass it over. 
53. Tettigonia feralis, sp.n. (Tab. XVI. fig. 22, 3.) 
Fusco-nigra, capite magno, triangulariter producto; pronoto levissime sculpturato, lateribus fere parallelis, 
basi vix sinuaté; scutello magno; tegminibus levibus, venis distinctis.
