262 HEMIPTERA-HOMOPTERA. 
Hab. Nicaracua, Chontales (Janson); Panama, David and Bugaba in Chiriqui 
(Champion).—Sovutn America }, S. Paulo 23. 
This insect, of which there is rather a large series in our collection, has not been 
recorded before from Central America. 
We figure a specimen from Bugaba. 
75. Tettigonia sociata, sp.n. (Tab. XVII. fig. 15.) 
T. sexguttate precipue affinis, sed capite subtriangulari, minus antice rotundato, capite pronotoque nigris, 
unicoloribus, maculisque tegminum facile distinguenda. 
Of a deep velvety-black colour, unicolorous, with two common white bands—one behind the scutellum 
stretching partly or nearly across the tegmina, and the other before the apex touching the suture and 
margins ; there is also a spot at the margin before the apex, and a small hyaline patch before this ; some- 
times the two bands are absent, and the whole upper surface is black with the exception of these one or 
two small light patches ; head subtriangu!ar, obtusely rounded at the apex, but not completely rounded as 
in 7. sewguttata ; legs whitish or light testaceous. 
Long. 6-7 millim. ; lat. ad hum. 1-14 millim. 
Hab. Panama, Bugaba (Champuon). 
76. Tettigonia jucunda. (Tab. XVII. fig. 16.) 
Tettigonia jucunda, Walk. List of Homopt. Ins. iii. p. 737"; Sign. Ann. Soc. Ent. Fr. 1853, p. 355, 
 t.1i. fig. 5%. 
Hab. Mexico (Mus. Brit.2), Rinconada (Schaus), Chiapas (MM. Trujillo), Teapa in 
Tabasco (H. H. Smith); Guatemata, Tactic, San Juan, and Cahabon in Vera Paz 
(Champion) ; Honpuras (Dyson !).. 
This pretty species is easily known by its coloration, the two oblong-oval patches 
of the red ground-colour being enclosed by a dark border on each tegmen. Signoret’s 
figure completely fails to do justice to the insect and is scarcely recognizable. 
A specimen from Teapa is figured.

This is apparently a very variable species. The ordinary form has the head marked 
with a broad sooty-testaceous line, often abbreviated, and the pronotum with two broad
