TETTIGONIA. 263 
testaceous lines meeting in front, the front of the scutellum being of the same colour. 
The ground-colour is brilliant crimson-scarlet, the tegmina being regularly marked 
with black and crimson; but in extreme varieties the testaceous colour covers the 
whole or almost the whole of the front parts, and the red colour on the tegmina is 
reduced to a few small spots. It is also very variable in size, ranging from 5-8 millim. 
in length. The chief varieties in our collection come from Chiriqui, the series from 
Teapa being very constant. 
The specimen figured is from Atoyac. 
78. Tettigonia guttata. (Tab. XVII. fig. 18.) 
Tettigonia guttata, Sign. Ann. Soc. Ent. Fr. 1854, p. 355, t. 12. fig. 4". 
Hab. Mexico} (Mus. Vind. Cws.); Hoxpuras, Ruatan I. (Gawmer); Panama (Boucard). 
This species may be known by the dark central longitudinal line on the vertex, and 
by the two dark more or less irregular longitudinal lines on the disc of the pronotum, 
which meet or nearly meet at the base of the line on the vertex, and enclose the central 
portion of the pronotum, which is red and immaculate. 
We figure a specimen from Mexico belonging to the Vienna Museum. 
79. Tettigonia coccinea, sp.n. (Tab. XVII. fig. 19.) 
Coccinea, nigro-variegata, haud nitida ; capite sat brevi, triangulari, oculis vix prominulis; fronte immaculata ; 
vertice et pronuto vitté media lat&é a medio illius ad hujus basim extensa, pronoti marginibus fuscatis ; 
scutello plerumque testaceo; tegminibus coccineis, nigro sat regulariter variegatis, apice laté fusco- 
hyalino ; alis fuscatis ; pectore pedibusque albidis. 
Crimson-scarlet, variegated with black, dull; head small, triangular; vertex with a broad dark band starting 
from the middle and continued to the base of the pronotum, the margins of the latter fuscous, the space 
on either side of the dark pronotal band being more or less obscurely testaceous; frons red, without 
markings; scutellum testaceous; tegmina crimson-scarlet, with rather regular black markings, the 
markings being mostly zigzag and confluent, the apex rather broadly fusco-hyaline; there is a white 
patch touching the costa just before the apical portion; wings dark; abdomen red; chest and legs 
whitish. 
Long. 9 millim.; lat. ad hum. 2 millim.. 
Hab. Mexico (Sallé, in Mus. Holm.), Atoyac in Vera Cruz (H. H. Sinith). 
Dr. Aurivillius sent me an example of this species among some unnamed insects 
from the Stockholm Museum. 
A specimen from Atoyac is figured. 
80. Tettigonia bilimeki, sp. n. (Tab. XVII. fig. 20.) 
Preecedenti valde affinis, sed major, coccinea immaculata, vittaé centrali furcataé ab apice frontis usque ad 
basim pronoti continuaté, hujus lateribus haud fuscatis, tegminibus margine costali tantum et apice 
fuscatis. 
Very like the preceding (7. coccinea), but with the tegmina crimson-scarlet, except the costal margin at the 
apex, and with the broad central band on the front portion of the body continued from the apex of the frons
