_ADIPPE.—ANTIANTHE. 137 
regulariter a humeris prominulis ad apicem exteusis; tegminibus ut in specie preecedenti ; corpore subtus 
pedibusque testaceis. 
Elongate and proportionally narrow, with the pronotum subparallel in front and gradually narrowed behind, 
finely punctured, with a central keel which is well marked, and, if viewed from the side, rather flatly but 
evenly rounded, of a brownish-grey colour, marbled on the metopidium with darker colour and obscurely 
variegated on the rest of the surface; on either side there are more or less regular coste ; tegmina as in 
the preceding species ; underside and legs testaceous. 
Long. 5 millim. ; lat. int. hum. 2 millim. 
Hab. Panama, Bugaba (Champion). 
The long and narrow shape and general sculpture will easily distinguish this insect 
from the preceding. 
ANTIANTHE, nom. nov.* 
Janthe, Stal, Ofv. Kongl. Vet.-Ak. Forh. 1867, p. 554 (nec Marseul, 1865). 
This genus comprises three or four species from Central or Tropical South America. 
They may be known by the strongly elevated pronotum, which is highest in front and 
covers a considerable portion of the tegmina, and the sharp horizontal pronotal horns, 
and by the fact that the corium has two discoidal areas. The apex of the hind tibie 
and the tarsi are peculiarly spined, as shown on Tab. VIII. fig. 216. It is hard to 
determine how many species are really distinct, as they lead one into the other; this 
is especially noticeable in a large series, such as that in our collection, which numbers 
more than two hundred examples. ‘The size is very variable, but the males appear to 
be always considerably smaller than the females from the same locality.

Hab. Nortu America, California——Mexico1?24, Omilteme and Xautipa in Guerrero, 
Cuernavaca in Morelos, Fortin in Vera Cruz, Teapa in Tabasco (H. H. Smith), Jalapa 
(F. D. G.), Orizaba (F. D. G. & H. H. S.), Atoyac in Vera Cruz (Schumann); Britisu

raaua, Chontales (Janson) ; Costa Rica, Volcan de Irazu, Rio Sucio (Rogers) ; Panama, 
Volcan de Chiriqui (Champion).—Co.omaia 2, Bogota. 
Of this species we have received a large series of both sexes from Orizaba and 
Atoyac ; some of the examples from Teapa and Chiriquiare very small. It appears to 
be one of the commonest and most widely spread of all the Homoptera in Central 
. * Vide supra, p. 89.
