246 : HEMIPTERA-HETEROPTERA. 
posterior margin slightly, but truncately, ampliated at base of scutellum, and with a bisinuate transverse 
carination between and a little in front of the lateral angles. Scutellum with a central longitudinal 
carination. Corium with the lateral margins subparallel; cuneus longer than broad. Rostrum mutilated. 
1. Vannius rubrovittatus, n. sp. (Tab. XXIV. fig. 11.) 
Body above very pale brownish ochraceous ; basal joint of antenne, inner area of eyes, lateral margins of the 
pronotum, scutellum (excluding basal angles), a subclaval fascia, a curved transverse fascia on apical 
third of corium, and a large quadrate spot at base of cuneus rosy red. Legs pale obscure ochraceous, the 
apices of the femora somewhat darker. Abdomen beneath more or less fuscous; sternum irregularly 
shaded with reddish or fuscous. Second, third, and fourth joints of the antenne obscure ochraceous, 
second and third with their apices greyish white. Corium, especially the costal margin, distinctly pilose. 
Long. 33-4 millim. 
Hab. Guatemaa, Las Mercedes, Cerro Zunil (Champion); Panama, Volcan de 
Chiriqui 2000 to 3000 feet (Champion). 
Found by beating the with red leaves of the banana, Musa, sp. (Champion). 
MONALONION. 
Monalonion, Herrich-Schaffer, Wanz. Ins. ix. p. 168 (1858); Walk. Cat. Het. vi. p. 47 (1878). 
This genus possesses many well-marked characteristics to prevent it being confused 
with any of the other genera here enumerated. The head is very broad and anteriorly 
deflexed, the sulcation is broad and subfoveate, the basal joint of antenne very short 
and stout, remaining joints much more slender, gradually weakening, and distinctly 
and strongly pilose. ‘The cuneus is much longer than broad. 
Monatonion is found throughout the length of the Neotropical Region, to which it 
appears to be confined. 
Frequently found in the withered leaves of the banana, Musa, sp. (Champion). 
a. Posterior tibie straight. 
1. Monalonion annulipes. (Tab. XXIII. fig. 25, var.) 
Monalonion annulipes, Sign. Ann. Soc. Ent. de Fr. sér. 8, vol. vi. p. 500’. 
Hab. Mexico! (Deppe, Mus. Berol.); Guaremaa, San Geronimo (Champion); Panama, 
Bugaba, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
With the series of specimens now before me, including a typical specimen sent 
by Dr. Signoret, I cannot but consider this to be a most variable and protean species. 
The head and antenne are always black, the last having the base, or sometimes nearly 
the whole, of the first joint more or less yellowish; the pronotum varies from black 
with the margins brownish (as described by Signoret) to either wholly black or com- 
pletely ochraceous; the corium also varies in a similar manner. The character, 
however, which is constant, and in my view always indicates this protean species, is 
the annulated posterior femora. 
A Mexican variety belonging to the Berlin Museum is here figured.
