134 HEMIPTERA-HETEROPTERA. 
pronotum with a transverse fascia in front, the connexivum, and the venter, except at the sides anteriorly 
fulvous; the body clothed with fine brownish pubescence, the head and the sides of the pronotum and of 
the terminal abdominal segments with long hairs; the antenne clothed with fine hairs, the two basal joints 
also with scattered sete; the legs thickly clothed with long hairs and scattered seta. Head with a 
smooth impressed median line; antenne with joint 2 about one-half the length of 1 (the other joints 
broken off). Pronotum abbreviated and rounded behind, with indications of a median ridge anteriorly. 
Abdomen gradually narrowing from the base; the first and second ventral segments strongly, longitu- 
dinally carinate down the middle, the sixth segment deeply triangularly emarginate at the apex, leaving 
the first genital segment exposed. Anterior tibie slightly hollowed at the apex beneath. Intermediate 
tarsi with the second joint slightly longer than the third. Posterior femora greatly incrassate, armed 
with numerous teeth, which are placed in two rows along the centre, those of the upper row unequal in 
length, there being three longer teeth towards the middle and two beyond it; posterior titi denticulate 
and strongly sinuous, the teeth along the apical third slightly longer than the others, the apex unarmed. 
Length nearly 6, breadth 13 millim. 
Hab. Mexico (Bilimek, in Mus. Vind. Ces.). 
One specimen. Allied to &. crassipes, but differing from the apterous male of that 
species in the less thickened posterior femora, the posterior tibie without long teeth at 
the apex, the second joint of the intermediate tarsi longer, the sixth ventral segment 
triangularly emarginate at the apex, &c. The more thickened posterior femora and the 
sinuous posterior tibie separate 2. varipes from the males of 2. armata, R. distincta, &c., 
the last-mentioned character distinguishing it from 9. femoralis. Also very like 
&. collaris, but larger and more elongate, with longer legs and antenne, the anterior 
tibie undilated in the male, &c. 
8. Rhagovelia femoralis, n. sp. (Tab. VIII. fig. 23, apterous 3.) 
Apterous form. . Moderately elongate, robust, fusiform, black, the base of the antenns, a narrow transverse 
band on the pronotum just before the apex, the front of the prosternum, the anterior coxe and trochanters, 
the anterior femora broadly at the base and in great part beneath, the middle coxe, the hind coxe and 
trochanters, the hind femora within, beneath, and at the base, and the venter in the middle at the apex, 
flavous or fulvous; the pleura and the sides of the abdomen bluish-grey; the body, legs, and antenne 
clothed with short, very fine, brownish pubescence, the sides of the body, the head, the two basal joints 
of the antenne, and the legs clothed also with long hairs and sete. Head with a smooth impressed 
median line; antenne comparatively short, joint 1 about twice as long as 2, 2-4 subequal in length, 
4 fusiform, pointed at the tip. Pronotum abbreviated and rounded behind. Legs stout, the middle pair 
very long, the hind pair comparatively short ; posterior femora enormously incrassated, armed with two 
rows of rather long teeth, extending from about the basal third to near the apex, and with one much 
longer tooth at the basal third ; posterior tibie almost straight, denticulate within, and armed with one 
long tooth at some distance from the apex and another at the apical angle; posterior trochanters denti- 
culate beneath ; intermediate tarsi with joint 2 slightly shorter than 3. Ventral segments 1-5 with a 
median ridge, which becomes evanescent posteriorly. 
Length 43, breadth (of the pronotum) 13 millim. 
Hab. Panama, Pefia Blanca (Champion). 
One example. Allied to #. crassipes, but much smaller, with relatively shorter 
hind legs, the armature of both femora and tibie very different, the antenne shorter, 
the intermediate tibie relatively shorter, the metasternum without tubercle in the 
male, &c. #. collaris (Burm.), from the Antilles and South America, one of the types 
of which is before me, is very like the present species; but it has the anterior
