182 -HEMIPTERA-HETEROPTERA. 
This genus contains about a dozen described species, all but one or two of which are 
American. It is easily recognizable by the spiniform prolongation of the basal joint 
of the antenne, this latter being stout and rigid and extending beyond the point of 
insertion of the second joint, the joints 2-4, which are very slender, folding backwards 
in repose and received (with the rostrum) in the groove along the underside of the 
head. 
Antenne with the basal joint extending far beyond the point of articulation 
with the second joint, and spinose beneath; anterior femora and tibize 
armed beneath, along both edges, with very long spines of unequal length ; 
eyes not prominent . . 2. 2. 1 1 1 ee ew ew ww we we ©) Spinimanus, n. sp. 
Antenne with the basal joint extending to a little beyond the point of articu- 
lation with the second joint; anterior femora armed beneath, along both 
edges, and the anterior tibiz on the inner edge, with long spines ; eyes 
prominent.

1. Pnirontis spinimanus, n. sp. (Tab. XI. figg. 10,104, ¢.) 
@. Very elongate, narrow, subfusiform ; pale greyish-ochreous, the elytra with a small nigro-fuscous spot 
on the inner part of the discal cell, the costal margin whitish, the two terminal joints of the antenne 
fuscous, the venter with two narrow fuscous vitte, the spines on the anterior legs annulated with 
fuscous, the spiracles blackish ; the basal joint of the antenne, the head, pronotum, and pleura finely 
granulate, the rest of the body sparsely clothed with very short, fine, scale-like hairs ; the basal joint of 
the antennz beneath, and the head on each side beneath, before and behind the eyes, armed with a row 
of setiferous spines, those on the posterior portion of the head tending to coalesce in pairs. Head 
cylindrical, as long as the pronotum, the ante-ocular portion rather longer than the post-ocular portion, 
the eyes not prominent, the ocelli small, the antenniferous tubercles scarcely produced in front, the two 
frontal spines short, the gene moderately prominent; antenn with the basal joint stout, rigid, as long 
as the head, tapering forwards, extending to nearly one-half its length beyond the point of articulation 
with the second joint, the latter long and slender, reaching to the anterior margin of the eye, joints 3 
and 4 very slender, 3 short, 4 three times the length of 3. Pronotum longer than broad, narrowing 
forwards, carinate at the sides, the anterior lobe canaliculate down the middle, the anterior angles armed 
with a short oblique spine, the hind angles a little swollen. Scutellum produced into a short spine 
behind. Elytra reaching the base of the sixth segment. Abdomen a little rounded at the sides, narrowing 
from about the middle; sixth dorsal segment arcuate-emarginate at the apex; first genital segment 
transverse, rhomboidal ; second genital segment long, bilobed at the tip. Anterior femora armed beneath 
on the inner edge with six, and on the outer edge with four long spines, these becoming very much 
longer outwards, between which is a series of very short setiferous spines ; anterior tibise bowed inwards, 
armed on the lower inner edge with three, and on the outer edge with four long spines, the apical outer 
spine exceedingly elongate (a little longer than the tarsus), and with a few very short setiferous spines 
between them. Prosternal spines long and acute. Venter carinate to the apex of the fifth segment. 
Length 13, breadth 2 millim. 
Hab. Guatmmata, near the city (Salvin). 
One specimen. This remarkable insect is closely allied to the South-American 
P. serripes (Fabr.), but it differs in numerous details from Stal’s lengthy description of 
that species (Hemipt. Fabr. i. pp. 126-128).
