TETTIGONIA. . 275 
At first sight this species somewhat resembles 7. diducta, but may easily be known 
by the shape of the head and the indistinct venation of the tegmina. 
116. Tettigonia prolixa, sp.n. (Tab. XVIII. fig. 18.) > s//™/ fis (wall ) 
Parva, viridis; capite brevi, obtuso, oculis prominulis, hoc et parte anteriori pronoti testaceo, delicate nigro- 
figurato; fronte testacea, transversim nigro-lineata; pronoto convexo, nitido; scutello testaceo, maculis 
duabus nigris parvis ad basim instructo; tegminibus suturé peranguste testaced, apice hyalino; alis 
fumosis ; abdomine supra nigro, corpore subtus testaceo, plus minusve fusco-variegato ; pedibus testaceis. 
A very small and insignificant green species, with the head short, very obtusely angled, and the eyes moderately 
prominent; forehead and head testaceous, the former with fine transverse black lines, and the latter, 
together with the anterior part of the pronotum (which is testaceous or greenish-testaceous in front and 
at the sides), distinctly figured with black; pronotum convex and shining; scutellum testaceous, 
unicolorous or with faint traces of figuration, with two small black spots at the base; tegmina with the 
suture narrowly, but usually distinctly, testaceous, apex hyaline; abdomen black above, the underside 
testaceous, variegated with fuscous ; legs testaceous, 
Long. 4-5 millim.; lat. 1-13 millim. 
Hab. Mexico (Sallé), Orizaba (F. D. Godman & H. H. Smith), Tierra Colorada in 
Guerrero, Vera Cruz, Atoyac, Frontera, and Teapa in Tabasco (H. H. Smith). 
This species, though very insignificant in appearance, seems to be distinct and 
constant, and is very easily known by the delicate figuration of the head and the front 
of the pronotum. ‘There is a considerable series in our collection, all from Mexico. 
I at first described this insect under another name, but I find that it is identical with 
three specimens in the Belgium Museum labelled ‘“ Guadeloupe, Delauney,’ and named 
“ T. proliaa, Lethierry, n. sp.” I do not known whether a description of the species 
has been published by M. Lethierry or not, but I have adopted his name in order to 
avoid confusion if such is the case. 
An example from Atoyac is figured. 
117. Tettigonia virgaticeps, sp.n. (Tab. XVIII. fig. 19.) 
Viridis, nitida; capite flavo, vitté sat lata irregulari inter oculos nigra, modice producto, rotundato, oculis 
prominulis; fronte vix nigro notaté; pronoto vix capite longiori, viridi, antice flavescenti; scutello 
flavo ; tegminibus fere unicoloribus, apice hyalino, ad extremum fumosis; alis fumosis; abdomine supra 
nigro; corpore subtus cum pedibus dilute flavis vel testaceis. 
A rather small, shining, bright green species, easily recognizable by the rather large yellow head, which has a 
well-marked irregular black band running across between the upper margin of the eyes, these being slightly 
prominent; pronotum scarcely, if at all, longer than the head, lighter in front; scutellum testaceous, with 
very faint traces of darker lines; tegmina lighter at the margins, especially in front, hyaline at the apex, 
the extreme tips smoky; wings dark; abdomen fuscous above; underside and legs light yellow, claws 
black. 
Long. 6 millim.; lat. vix 2 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
A small series.
