TETTIGONIA. 255 
Mas, minor et angustior, magis nitidus, capite magis excavato, oculis prominulis; tegminibus levioribus, apice 
extremo subhyalino; vertice ad apicem, metopidio et pedibus late rufo-flavis; corpore subtus albido- 
testaceo. 
Femina, major et latior, minus nitida, capite minus excavato, oculis minus prominulis ; tegminibus vix nitidis, 
apice subhyalino ; corpore subtus flavescenti, abdomine ad medium subnigro ; pedibus piceis. 
Black or fuscous-black, with the head triangularly produced, the pronotum very finely sculptured and its 
base very gently sinuate; tegmina smooth, with distinct veins, the two claval veins being parallel and 
distant. 
Male smaller, narrower, and more shining, with the extreme front of the vertex, metopidium, and legs bright 
orange, and the underside light testaceous-yellow or whitish-testaceous; head more excavate and more 
plainly ridged at the sides and front, with the ridging distinctly rugose, and with a fine central furrow; 
tegmina smoother and more shining, with the extreme apical margin subhyaline. 
Female larger, broader, and duller, with the upper surface more fuscous, the metopidium (except in front) and 
the underside yellowish, except the central part of the abdomen, which is pitchy; head less excavate 
and less plainly ridged, eyes iess prominent ; tegmina with the apex more broadly hyaline. 
Long. 5, 11 millim., lat. ad hum. 3 millim.; 9, long. 12 millim., lat. ad hum. 32 millim, 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
I at first described these as two species, but I believe that they are sexes of one only, 
as I can find no tangible point of difference between them, and they both come from 
the same locality.

An elongate narrow species, black, with the tegmina orange, or with the front parts orange-testaceous and 
the apical parts a bright orange; the line bounding the clavus, the apex, the suture from the apex to the 
clavus, an oblique line behind the middle touching the margin, and the margin itself for part of its length 
very narrowly, are black; head produced, rounded obtusely in front, with the vertex impressed or sulcate 
in the middle. black, with the metopidium and a faint line on the vertex testaceous ; pronotum and 
scutellum finely sculptured ; tegmina very finely and closely punctured ; underside reddish; legs pitchy, 
femora rufescent; a small light spot is often present near the margin between the dark apex and the 
orange ground-colour of the succeeding portion of the tegmina.

We figure a specimen from Bugaba.
