PHERA. 221 
I have only seen one example of this insect, which, apart from the characters of the 
head, appears to be closely related to certain species of Aulacizes. St&l compares it to 
P. centrolineata, Sign., to which, superficially, it seems to bear a very slight resemblance, 
being much broader and more robust. | 
2. Phera atra. 
Proconia atra, Walk. List of Homopt. Ins. iii. p. 789 (1851) '. 
Tettigonia atra, Sign. Ann. Soc. Ent. Fr. 1854, p. 492, t. 17. fig. 9’. 
Proconia contraria, Walk. loc. cit. p. 789°. 
Hab. Mexico (Sallé, in Mus. Brit. ?), Valladolid in Yucatan (Gaumer); Britis 
Honpuras, Belize (Blancaneaur); GuateMaLa, Teleman in Vera Paz (Champion) ; 
Honpuras? (Dyson 1%); Nicaragua, Chontales (Janson); Panama (Boucard), Volcan 
de Chiriqui .(Champion).—Gutana, Cayenne 2. 
This is the largest species of the genus. The single specimen from Panama is a 
very large example, 20 millim. in length, and has the front of the head and the basal 
two-thirds of the pronotum red, and the legs clear red; it does not, however, appear 
to be anything more than a variety. 
3. Phera vitripennis. (Tab. XIV. figg. 1, 1a.) 
Tettigonia vitripennis, Germ. Mag. der Ent. iv. p. 61 (1821)'; Sign. Ann. Soc. Ent. Fr. 1854, 
p. 493, t. 17. fig. 10’.

in Yucatan (Gaumer); Nicaragua, Mosquito Coast >.—Brazi !. 
I believe that the above synonymy will prove to be correct, as 7. vitripennis is 
mentioned by Signoret ? as a common species in Brazil and California, and therefore 
is sure to occur in Central America, and Walker's two species, as well as 7. ichthyo- 
cephala (of which there are specimens from Mexico in Signoret’s collection in the 
Vienna Museum), appear to agree well with the description and figure, allowing for the 
variation which appears to be present in many of the Tettigoniide. This variation in 
colour is very evident in a series in our collection from Presidio, Mexico. A specimen 
from Atoyac is figured.
