264 HEMIPTERA-HOMOPTERA. 
to the base of the pronotum, with a very slight interruption at the apex of the vertex ; the white spot, 
moreover, before the apical fuscous portion is absent. 
Long. 10 millim. ; lat. ad hum. 2 millim. 
Hab. Mexico, San Marcos (Bilimek, in Mus. Vind. Ces.). 
It is possible this may prove to be a variety of the preceding, but it has a very 
different appearance. 
81. Tettigonia mexicana. 
Tettigonia mexicana, Sign. Aun. Soc. Ent. Fr. 1855, p. 789, t. 24. fig. 7°. 
Hab. Mexico (Mus. Berol.'). 
Among some insects sent to me from the Vienna Museum as undetermined I found 
two specimens labelled ‘“ 7. mexicana, det. Signoret”; this is, evidently, however, a 
mistake, as they are both red insects, one being 7. magica and the other a variety of 
T. blanchardi or an allied species: the true 7. mexicana appears to be entirely yellow, 
with numerous fine dark markings. I have not seen a typicalsexample and cannot 
identify it in our collection. 
82. Tettigonia tessellata. 
Tettigonia tesseliata, Sign. Ann. Soc. Ent. Fr. 1835, p. 790, t. 24. fig. 9°. 
Hab. Mexico (Mus. Berol.1); Guatemaa (Mus. Paris). 
This species is not apparently represented in our collection, nor have I seen an 
example. According to Signoret’s figure it has the upper surface evenly tessellated and 
marked with yellow and black: in his Latin diagnosis he says: “ Rufescens, brunneo 
lineolata et reticulata” ; and in the French description: “Jaune, linéolée et réticulée 
de brun-rouge.”’ | 
88. Tettigonia vulnerata. (Tab. XVII. fig. 21.) 
Tettigonia vulnerata, Sign. Ann. Soc. Ent. Fr. 1855, p. 782, t. 23. fig. 20°. 
Hab. Mexico, Tierra Colorada in Guerrero (H. H. Smith); Guatemaa (Mus. 
Paris‘), San Gerénimo (Champion). 
The specimen figured is from Tierra Colorada. 
84. Tettigonia recta, sp.n. (Tab. XVII. fig. 22.) 
Angusta, parallela, fusca flavo-variegata; capite obtuse triangulari, testaceo, maculis brunneis; pronoto 
convexo, fusco colore dilutiori obscure variegato ; tegminibus parallelis, fuscis, maculis tribus dilute flavis ; 
abdomine fusco; sterno pedibusque dilute testaceis. 
A narrow, parallel species; head obtusely triangular, eyes scarcely prominent beyond the sides of the triangle, 
testaceous, variegated with light fuscous; pronotum convex, dark, obscurely variegated with lighter colour ; 
scutellum variegated ; tegmina parallel, fuscous, with three lemon-coloured patches on each—one at the
