TETTIGONIA. 265 
base, one behind the middle, and a small one at the margin between these, the apex subhyaline; abdomen 
fuscous ; sternum and legs light testaceous, apex of the posterior tibise and the tarsi fuscous. 
Long. 6 millim.; lat. ad hum. 14 millim. 
Hab. Mexico, San Marcos (Bilimek, in Mus. Vind. Ces.), Venta de Zopilote and 
Amula in Guerrero (H. H. Smith). 
This species apparently belongs to the 7. venusta group. 
We figure a specimen from Venta de Zopilote. 
85. Tettigonia xqua, sp.n. (Tab. XVII. fig. 23.) 
Fusco-brunnea, antice albido et griseo variegata, tegminibus plus minusve obscure rufo vel griseo-rufo varie- 
gatis; capite producto obtuse rotundato, oculis vix prominulis ; pronoto capite paullo longiori; tegminibus - 
sat parallelis ; abdomine supra fusco; corpore subtus et pedibus testaceis, plus minusve infuscatis. 
Parallel, fuscous or fuscous-brown, with the head, pronotum, and scutellum variegated with lighter and darker 
shades of brown, as well as with greyish and testaceous colour; head produced, obtusely rounded in front ; 
pronotum a little longer than the head; tegmina scarcely narrowed to the apex, with several irregular 
red or greyish-red spots on each, more or less obscure, apex subhyaline, with a little clear hyaline spot on 
each tegmen near the costal margin; abdomen fuscous above ; underside and legs testaceous, more or 
less infuscate. 
Long. 6-7 millim, ; lat. ad hum. 13 millim. 
Hab. Mexico (Boucard, in Mus. Holm.), Cuernavaca in Morelos (H. H. Smith) ; 
GuaTEMALA, San Gerénimo (Champion). 
This insect appears to be closely allied to 7. recta, and at first I was inclined to 
regard it as a variety of that species; but the coloration is not the same and the head 
is a little differently shaped. ‘The specimen from San Gerénimo may possibly belong 
to another species, but I do not feel justified in separating it. 
An example from Cuernavaca is figured. | 
86. Tettigonia albiceps, sp.n. (Tab. XVII. fig. 24.) 
Parva, fusca, fusco-rufo obscure notata; capite magno, producto, rotundato, albido, oculis prominulis ; 
pronoto capite haud longiori, antice anguste albido; scutello ad medium late albido; tegminibus ad 
apicem obscure subhyalinis ; abdomine supra lete rufo; corpore subtus et pedibus albidis vel albido- 
testaceis. 
A small, insignificant, fuscous species, with obscure red markings ; head large, produced and rounded, about as. 
long as the pronotum, whitish-testaceous, with two minute brownish spots at the base; forehead light 
brown, with two testaceous spots, one above the other, in the middle surrounded by dark colour; pro- 
notum comparatively short, light in front, with two reddish spots on the anterior margin, joining the 
dark colour; tegmina obscurely suffused with red, especially at the claval suture; abdomen crimson 
above ; underside and legs very light testaceous. 
Long. 5 millim.; lat. ad hum. 1 millim. 
Had. Panama, Bugaba (Champion). 
This is an obscure little species, but it appears to be quite distinct, and may be 
easily known by its large, rounded, whitish head.
