et femoribus nigricantibus ; pedibus posticis, tarsis apiceque tibiarum exceptis, nigris, ungulis nigris; 
abdomine nigro, apicibus segmentorum testaceis; tegminibus hyalinis, basi extrem4, maculaque parva 
media, venisque incrassatis, nigricantibus. 
Shining black, ocelli and eyes whitish, pronotum closely and very distinctly punctured, with a smooth central 
line throughout its length, apical spines testaceous at the base; anterior and intermediate pairs of legs 
testaceous, with the base of the tibia and the femora dark, the posterior pair very long, with the femora 
and tibize, except a broad ring just before the apex, dark; abdomen dark, with the segments testaceous at 
apex ; tegmina reaching considerably beyond the apex of the pronctum, vitreous-hyaline, with the extreme 
base, a spot covering a portion of the interior discoidal area, and the thickened veins, black or fuscous; 
wings with the veins dark towards the apex, light and scarcely traceable behind. 
Long. cum tégm. 43 millim.; lat. int. hum. 2 millim, 
Hab. Mexico, La Venta in Guerrero (H. H. Smith). 
One male specimen. As above stated, the central spine of the apex of the pronotum 
is broken; this is not apparent at first sight, as it looks merely rudimentary, but when 
examined under a compound microscope the fracture is evident; the spine is probably 
longer than the two lateral spines. 
CYPHONIA.

Ins., Hémipt. p. 548 (1843) ; Stal, Ofv. Kong]. Vet.-Ak. Forh. xxiv. p. 551 (1867). 
As originally constituted, Cyphonia would now contain a considerable number of 
species, chiefly from Brazil or Central America. Stal, however, rightly divides the 
genus, but has assigned his new name Poppea to the largest division of it. The genus 
Cyphonia, which includes the well-known Cyphonia clavata and certain allied species, is 
chiefly distinguished by the presence of two upright intermediate blunt spines on the 
back of the pronotum, which are entirely wanting in Poppea. These insects are 
amongst the strangest and most abnormal of the Homoptera; in the venation of the 
tegmina they are allied to Ceresa, but they have a perfectly distinct facies.

This insect is probably widely distributed throughout Tropical America, A specimen 
from Bugaba is figured.
