246 HEMIPTERA-HOMOPTERA. 
28. Tettigonia stali. (Tab. XV. fig. 28.). 
Tettigonia stalii, Sign. Ann. Soc. Ent. Fr. 1855, p. 787, t. 24. fig. 5°. 
Hab. Mexico (Mus. Vind. Ces.), Atoyac in Vera Cruz, Teapa in Tabasco (H. H. 
Smith) ; GuaTeMALA, Pantaleon, San Isidro, and Cerro Zunil (Champion). 
This species is rather closely allied to 7. granulata, but differs in the distinct large 
yellow stripes and markings. 
ar. fractinota,n. (Tab. XV. fig. 29.) 
Vittis longitudinalibus flavis plus minusve fractis vel abbreviatis, vel ad partem deficientibus facile distin- 
guenda. 
Of a bright dark crimson colour, with the front parts darker, and the usual longitudinal yellow or orange 
spots abbreviated or, especially on the tegmina, broken up into short patches or spots; on the average 
the size appears to be somewhat smaller. 
Long. 8-9 millim.; lat. ad hum. 2-22 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemata, San Isidro (Champion) ; 
Nicaracua, Chontales (Janson). 
I should describe this as a new species but for the occurrence of distinctly inter- 
mediate forms, and also of two or three specimens of undoubted 7. sta in our long 
series from Teapa, which all appear to belong to one variable insect. | 
A type specimen from Pantaleon and one of the variety from Teapa are figured. 
29. Tettigonia pumicata, sp.n. (Tab. XVI. fig. 1.) 
Elongata, postice acuminata, nitida; capite pronotoque nigris, testaceo obscure maculatis, illo breviter producto, 
perobtuse rotundato, oculis prominulis, hoc convexo levissime transversim striato, basi fere recta; scutello 
magno, nigro, immaculato; tegminibus rubris, levibus, apice haud hyalino; corpore subtus rubro; pedibus 
rufis vel rufo-piceis. 
A moderate-sized species, acuminate behind when the tegmina are folded, smooth and shining; head and 
pronotum black, vertex with four testaceous spots at the base, slightly produced before the eyes, very 
obtusely rounded ; head with the eyes, which are rather prominent, about as broad as the base of the 
pronotum; pronotum convex, finely transversely rugose, with minute testaceous spots; scutellum 
shining, immaculate ; tegmina smooth, somewhat tectiform, red, without markings, and not hyaline at 
the apex; wings dark; underside of the body red, the segments of the abdomen partly black ; legs red 
or pitchy-red. 
Long. 10 millim.; lat. ad hum. 24 miilim. 
Hab. Panama, Volcan de Chiriqui 3000 to 6000 feet (Champion). 
This species somewhat resembles 7. rutilans, Walk. (nec Fabr.), but differs in the 
shape of the head, the concolorous tegmina, and the testaceous markings on the base 
of the vertex and on the pronotum. 
30. Tettigonia guerreroensis, sp.n. (Tab. XVI. fig. 2.) 
Brevis, robusta ; capite pronotoque testaceis, nigro brunneoque figuratis, illo breviter triangulari, oculis haud 
vel vix prominentibus; metopidio nigro, testaceo irrorato, hoc levissime sculpturato, basi leviter supra 
scutellum sinuaté; scutello antice nigro, maculis duabus parvis ocellatis ad basim, postice testaceo;
