94 HEMIPTERA-HETEROPTERA. 
1. Brachyrrhynchus abdominalis. (Tab. VI. fig. 23, ¢ .) 
Brachyrhynchus abdominalis, Stal, Enum. Hemipt. iii. p. 144 (¢)’; Bergr. Verh. zool.-bot. Ges. 
Wien, xxxvi. p. 59’. 
9. Ovate, broad, nigro-piceous, the connexivum above and beneath mottled with ferruginous, the venter 
obscure ferruginous, the apices of the connexival segments above and beneath more or less ochraceous, 
the tips of the antenne, the tarsi, and the tubercles on the head, pronotum, and scutellum ochraceo- 
ferruginous ; the membrane nigro-fuscous, with two obscure luteous spots at the base; the upper surface 
rather coarsely granulate, and sparsely clothed with very short, minute hairs, the head with numerous 
tubercles along the middle, the anterior portion of the pronotum with several tubercles arranged in four 
longitudinal rows on the disc (the inner basal two conspicuous), and the scutellum with a tubercle on 
each side in front. Head subquadrate ; the apical process moderately long, finely denticulate at the sides, 
and unemarginate at the tip, extending to near the apex of the first antennal joint; the spiniform 
antenniferous processes long, acute, and slightly divergent; the post-ocular portions broad, rounded 
behind, and armed with a short, oblique tooth, which projects slightly beyond the eyes ; antennz slender, 
with a stouter basal joint, joints 1-3 increasing in length, 4 shorter than 1, piriform, pilose at the tip. 
Pronotum rather deeply emarginate at the base, and strongly constricted at the sides; the anterior 
portion dilated on each side laterally and anteriorly into a short, broad lobe, which is rounded externally, 
and is obliquely truncate in front; the posterior portion very much wider, and rounded at the sides ; 
the margins rather coarsely crenulate. Corium rounded at the apex. Connexivum very broad, rounded 
externally, the margin finely crenulate, the fifth and sixth segments obliquely narrowing; the sixth 
segment rather deeply arcuate-emarginate at the apex, with the apical angles somewhat broadly produced 
and forming two short blunt prominences. The first genital segment produced into a short lobe on each 
side behind. Beneath rugose and granulate, the ventral segments 1-4 each with a smooth, posteriorly 
widening spot in the centre. Rostrum not extending beyond the base of the head, the groove very broad 
and open behind. Femora roughly granulate. 
Length 10, breadth 5 millim. 
Hab. Mexico (Sallé, in Mus. Paris)—ANvILLES, Cuba ?, Puerto Rico ?. 
Differs from all the other Central-American species of the genus in the rather deeply 
emarginate base of the pronotum, the broadly lobate anterior angles of which are 
obliquely truncate in front, and in having conspicuous pallid tubercles at the basal 
angles of the scutellum and on the disc of the anterior lobe of the pronotum behind. 
The description is taken from a Mexican specimen communicated by Dr. Bergroth. 
B. abdominalis, Stal, the type of which I have seen, is allied to B. bouvieri, Bergr., 
from Colombia. 
2. Brachyrrhynchus leviventris, n.sp. (Tab. VI. figg. 24, 25, 2.) 
@. Oblong, broad, black or piceous, the base and apex of the antennw and the tarsi usually more or less 
ferruginous, the tibie also sometimes inclining to ferruginous; the upper surface granulate, and some- 
what thickly clothed with very short, curled, rusty-brown hairs, these being matted together on the 
depressed parts; the antenne and legs finely pilose. Head (exclusive of the apical process) transverse ; 
the apical process long, broad, convex, extending to the apex of the first antennal joint, not or feebly 
emarginate at the tip; the spiniform antenniferous processes stout, rather short, subparallel; the post- 
ocular portions armed with a short tooth, and. obliquely converging thence to the base; antenne slender, 
moderately long, joints 1 and 2 subequal in length, 3 much longer than 2, 4 a little shorter than 2, 
piriform, with the base slender. Pronotum feebly emarginate at the base, constricted at the sides; the 
anterior portion dilated on each side laterally and anteriorly into a broadly rounded lobe, the two inner 
callosities somewhat prominent; the posterior portion about one-fifth wider than the anterior portion,
