Elongata, parallela, purpureo-rufa; capite nigro antice miniato, triangulari, modice producto, oculis sat 
prominulis; fronte nigra: pronoto virgis tribus longitudinalibus lete miniatis; scutello magno; 
tegminibus maculis vel lineis quibusdam obscuris fusco-purpureis; corpore subtus pedibusque dilute

Purple-red ; head deep black, with the front part scarlet and the extreme apex with two black spots (which, 
if viewed from the front, form the upper portion of the black frons), short, triangular, moderately 
produced before the eyes, which are rather prominent; pronotum with three distinct, broad, scarlet, 
longitudinal bands; scutellum large; tegmina with the margins united a little before the apex, and 
a more or less elongate patch on each side of the suture obscurely fuscous-purple ; underside and legs 
light testaceous.

This is a very distinct and pretty species, which may be known at once by the three 
scarlet bands on the pronotum. 
We figure a specimen from Bugaba.

67. Tettigonia costaricensis. (Tab. XVII. fig. 6.) 
Tettigonia costaricensis, Distant, Ent. Monthly Mag. xvi. p. 63°. 
Hab. Costa Rica, Rio Sucio and Volcan de Irazu 6000 to 7000 feet (Rogers ') ; 
Panama (Boucard). 
This species may at once be known by its entirely black colour, with the exception 
of an orange band, which, including the pronotum (except just the front portion), 
encircles the whole body. 
The specimen figured is from Panama.
