158 HEMIPTERA-HETEROPTERA. 
Apterous form. Subfusiform (¢), oblong-ovate (2); the pronotum abbreviated and rounded behind, the 
anterior lobe separated by a distinct suture; the upper surface uniformly clothed with brownish pubes- 
cence, the pronotum with greyish pubescence on each side in front. 
3 2. Posterior femora comparatively slender, not stouter than the intermediate femora, armed with a long, 
slender, acute tooth at about the middle, and with a row of very short teeth extending thence to near the 
apex ; posterior tibiz unarmed on their inner edge. 
Length of the winged male 4; breadth of the apterous female 13, of the pronotum of the winged male 13 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
One winged male example, one apterous female, two immature apterous males, and 
two nymphs have been received of this species, which differs from all others of the 
genus here described in the long, slender, posterior femora in the male—these being 
similarly formed in both sexes, and having a slender prominent tooth,—the slender 
antenne, &c. &. tenuipes is nearest allied to &. angustipes, from Grenada and 
St. Vincent *, it having the armature of the posterior femora similar; but has longer 
legs and antenne, and a much longer penultimate joint to the intermediate tarsi. 
The sete on the two basal joints of the antenne are few in number. ‘The neuration 
of the elytra is different from that of the allied species, the median longitudinal 
nervure being irregular, and at about the middle connected with the inner and costal 
nervures by more numerous transverse veins. The apterous female specimen has the 
thoracic sutures formed as in the genus Trochopus—e. g., the pronotum is reduced to 
a short lobe, and the larger posterior portion becomes mesonotum. The abdomen is 
short in both forms. 
8. Rhagovelia uncinata, n. sp. (Tab. IX. figg. 1, apterous ¢, from beneath ; 
2, winged 9; 24a, elytron.) 
Winged form. Moderately elongate, nigro-fuscous or rufo-fuscous, the front of the head, the base of the 
antennee, the pronotum with a broad band in front, the lateral and posterior margins, and an evanescent 
median line, the connexival margins broadly, and the under surface, flavous or testaceous, the venter 
sometimes with a fuscous stripe on each side; the legs black above, flavous beneath, the anterior femora 
at the base above, the posterior femora at the base and within, and the coxe and trochanters also more or 
less flavous ; the elytra blackish-brown; the body, legs, and antenne finely pubescent, the head, the sides 
of the body, and the three basal joints of the antennz somewhat thickly clothed with long hairs, the legs 
and joints 1 and 2 of the antenne also with scattered sete. Head with a smooth impressed median line; 
antenne rather slender, joint 1 one-half longer than 2, 2-4 decreasing in length, 4 pointed at the tip. 
Pronotum sparsely punctured, the posterior portion triangular, obtuse at the apex. LElytra extending as 
far asthe apex of the terminal process of the abdomen. Terminal genital segment in both sexes produced 
into a sharp spine at the apex. Legs rather slender; the posterior tibie armed with a long, slender 
hook at the apex in both sexes ; the intermediate tarsi with joint 2 much shorter than 3. 
do. Posterior femora moderately incrassate, armed with seven or eight acute, curved teeth, the two inner ones 
much longer than the others and widely separated (one at the middle, and one at about the basal third), 
the two or three apical ones very short; posterior tibie finely and obsoletely denticulate on their inner 
edge, the denticulation becoming more distinct towards the base. 
¢. Posterior femora less thickened, with the teeth usually a little shorter.
