186 HEMIPTERA-HETEROPTERA. 
triangularly produced on each side posteriorly, the apex appearing deeply arcuate-emarginate, and not 
quite covering the terminal genital segment. Ventral segments 1-3 carinate. 
Length 18; breadth of the pronotum 24, of the abdomen 34 millim. 
Hab, Mexico, Atoyac in Vera Cruz (Schumann). 
One specimen. The longer spines on the anterior trochanters and femora are black, 
and therefore very conspicuous.

Apronius, Stal, Hemipt. Afr. iii. p. 150 (1865); Hemipt. Fabr. i. p. 127, nota (1868); Enum. 
Hemipt. ii. p. 128. 
Head subcylindrical, armed along the centre beneath with two rows of setiferous spines; the ante-ocular and 
post-ocular portions about equal in length, the latter shorter in A. rapaw, Stal; the lower anterior portion 
produced beneath the short, obtuse, frontal spines, and rounded in front ; the eyes very large and rounded, 
narrowly separated beneath; antenne short, the basal joint much shorter than the head; rostrum with 
the basal joint slightly longer than the second, reaching about as far as the anterior margin of the eyes. 
Pronotum as long as broad, much longer than the head. Scutellum produced into a short, horizontal, 
spiniform process behind. Elytra ample, in both sexes extending to the apex of the abdomen, pointed at 
the tip. Abdomen in both sexes rounded at the sides, with very narrow connexivum, the two genital 
segments exposed in the female; venter carinate to the apex of the fifth segment. Anterior femora 
compressed and incrassate, armed with two rows of very short spines beneath, the anterior trochanters also 
with two short spines. Anterior tibie with an elongate spongy fossa at the apex beneath. Anterior tarsi 
distinctly 3-jointed. Posterior femora nearly reaching the apex of the abdomen in the male. 
Stal referred a single species, A. rapax, from Minas Geraes, Brazil, to this genus; an 
allied form from Panama is now added. Apronius is closely related to Oncocephalus, 
Klug, a genus including a number of species from all parts of the world; but differs 
from it in the armature of the underside of the head, the position of the eyes, and the 
pointed elytra. The definition given above will supplement that of Stal.

D5 
Elongate-obovate, sordid reddish-ochreous, slightly mottled with fuscous; the anterior lobe of the head with 
two posteriorly coalescent lines in the centre, and the posterior lobe with the sides and a broad posteriorly 
narrowing median vitta (leaving two pale oblique lines), the pronotum with a narrow median vitta, 
separating into. two lines posteriorly, and a median line on the scutellum, black or nigro-fuscous; the 
elytra with four very small velvety nigro-fuscous spots—one a little below the base, one on the inner part 
of the discoidal cell, a still smaller one nearer the inner margin, and one at. about the middle of the outer 
cell of the membrane; the legs yellowish-ochraceous, the femora much mottled with fuscous, the fuscous 
markings tending to become coalescent towards the apex of the anterior and intermediate pairs, the 
anterior and intermediate tibize with two or three fuscous rings, the posterior tibia: infuscate at the apex ; 
the entire under surface mottled with fuscous, the pleura partly blackish; the connexivum mottled with 
black; the antenne with the basal joint obscure ferruginous, the other joints ochraceous; the body 
sparsely clothed with very short scale-like hairs, the legs with fine hairs; the antenne finely pubescent, 
joints 2-4 clothed with long projecting hairs in the male, the apex only of joint 2 with long hairs in the 
female. Head armed along the centre beneath with two rows of four subequidistant setiferous spines— 
the two pairs between the eyes in the form of stout conical prominences, the others very short; the frontal 
spines short, obtuse, divergent; the base feebly bituberculate ; the eyes very large, rounded, and prominent 
in the male, a little smaller in the female; antenne with joint 1 moderately stout, nearly half the length 
of 2, 2 slender, 3 and 4 very slender and subequal in length. Pronotum rapidly narrowing from the base
