TETTIGONIA. 239 
A specimen of this very distinct species was sent me among some unnamed material 
from Signoret’s collection. 
11. Tettigonia lignea, sp. n. (Tab. XV. fig. 10.) 
Oblonga, parallela, sat lata; capite brevissimo, vix ante oculos producto, nigro-maculato; pronoto brevi, antice 
quam postice latiori, basi recta, testaceo ; scutello fusco-testaceo ; tegminibus brunneis, flavo irregulariter 
variegatis, vix nitidis, apice subhyalino; corpore subtus pedibusque testaceis. 
Oblong, parallel, rather broad; head very short, scarcely produced before the eyes, which are prominent, 
testaceous, with two black spots, one at the top of the metopidium, and the other at the base of the 
vertex ; pronotum rufo-testaceous, impressed in front, with the basal margin straight and narrower than 
the anterior margin ; tegmina brown, with irregular yellow markings, the chief of these forming a broad 
band at about the middle and a broad space just before the apex, both being divided by the brown veins ; 
abdomen and legs testaceous, anterior tibia and the apex of the intermediate and posterior pairs, and the 
tarsi in front, pitchy. 
Long. 12-13 millim. ; lat. ad hum. 34 millim. 
Hab. Mexico (Bilimek, in Mus. Vind. Cas.). 
12. Tettigonia quinquesignata. (Tab. XV. fig. 11.) 
Tettigonia 5-signata, Walk. List of Homopt. Ins., Suppl. p. 194°. 
Tettigonia multivirgata, Stal, Stett. ent. Zeit. xxv. p. 73’. 
Hab. Mexico? (Sallé!; Mus. Holm.; Mus. Vind. Cas.), Atoyac in Vera Cruz, 
Teapa in Tabasco (#. H. Smith), San Lorenzo near Cordova (MM. Trujillo) ; GUATEMALA, 
Lanquin, Cahabon, Purula, and Senahu in Vera Paz (Champion). 
This insect appears to vary considerably in size. The single specimen from Senahu 
differs slightly from the others, but it evidently belongs to the same species. 
A specimen from Atoyac is figured. 
13. Tettigonia mosaica, sp.n. (Tab. XV. fig. 12.) 
Preecedenti affinis, griseo-testacea, brunneo, hyalino testaceoque variegata ; capite ante oculos leviter producto, 
rotundato, metopidio nigro-lineato; pronoto levi, figurato; scutello magno; elytris nitidis, levibus, 
versicoloribus; abdomine supra fusco; corpore subtus pedibusque dilute testaceis, basi segmentorum 
nigro-maculata. 
Of a griseo-testaceous colour, mottled with brown, testaceous, and hyaline; head somewhat produced before 
the eyes, rounded, with a fine pattern in black lines, the eyes prominent; pronotum, scutellum, and 
base of tegmina tessellated with brown and testaceous (like mosaic-work), the latter with a distinct 
yellow spot at each margin and a smaller one behind, joining a large irregular hyaline band running 
right across the tegmina ; before the apex, which is hyaline, are six light spots arranged transversely ; 
abdomen fuscous above, the underside of the body and legs light testaceous, the base of each of the 
abdominal segments being marked with two black spots. 
Long. 9-10 millim.; lat. ad hum. 2-3 millim. 
Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.). 
There are two specimens of this species among some material sent to me from the 
Vienna Museum as undetermined. One of them is labelled “ semiclara, det. Signoret ” ;
