LABDACUS,—PEDO. 219 
and each is at least three diameters from the hind-lateral eye on its side. The transverse line of the hind- 
central and fore-lateral eyes is straight, that of the hind-centrals and hind-laterals considerably curved, 
the convexity of the curve directed forwards ; the interval between the eyes of each lateral pair is nearly 
equal to the diameter of the posterior eye. 
Legs long, tolerably strong, 1, 2, 4, 3; yellow in colour, armed with numerous long strong spines, mostly in 
a series of pairs beneath the tibia and metatarsi. Terminal tarsal claws 3. 
Palpi short, similar to the legs in colour; cubital and radial joints very short, with much the appearance of 
being forced one over the other; the radial joint has a short, broad, somewhat quadrate, apophysis, with a 
prominent point at its hinder corner on the outer side, and another larger one of a similar kind underneath, 
and on its inner side some strong tapering spines; the digital joint is long, narrow, drawn out into a 
gradually tapering point, armed with a slightly curved terminal claw and with numerous long strong 
tapering spines ; the length of the digital joint is equal to that of the humeral joint; the palpal organs 
are tolerably compact, complex, and placed beneath the basal half of the digital joint. 
The maxille and labium are normal, yellow, tinged with yellow-brown. 
Falces powerful, straight, a little porrected ; profile curved; colour yellow, with an oblique brown stripe and 
a black line in front and a shorter brown stripe on the outer side at the base. 
The sternum is almost diamond-shaped, the anterior extremity being, however, truncated, the posterior having 
a shurp point between the inner corners of the coxe of the fourth pair of legs, which are here as nearly as 
possible in contact. Colour of sternum yellow. 
Abdomen long, narrow, somewhat flattened, of a dull yellowish hue, mixed with brown and blackish. It was 
too much shrunken to admit of seeing the whole pattern, but there appeared to be on the upperside a 
long, narrow, central, tapering, pale marking, edged with blackish, extending about halfway to the 
spinners ; these are prominent, moderately long, the inferior pair longest and strongest ; the anal tubercle 
is large and composed of two strong basal and terminal (subconical) joints.

PEDO *, gen. nov. (fam. ? Drasside). 
Cephalothoraz oval, much longer than broad, lateral marginal indentations at the caput tolerably strong ; sides 
of caput nearly parallel, moderately convex above; profile slightly curved, nearly level. 
Eyes subequal, in two transverse rows of nearly equal length, rather wide apart, slightly curved, the convexity 
of the curve of the anterior row, looked at from above and behind, directed forwards, that of the posterior 
row backwards. The four centrals form a quadrangle whose length is a little greater than its breadth, 
and its fore side a little shorter than the hinder one. The fore-lateral eyes are a little the largest. The 
height of the clypeus is nearly equal to half that of the facial space. 
Legs not very long, moderately strong, 4,1, 2,3 or 4, 1, 3, 2, but little difference between 1,2, and 3,—2 and 
3 in fact almost if not quite equal,—furnished with slender, and not very long, spines, chiefly in a series of 
pairs beneath the metatarsi and tibie—3 pairs beneath the former, 2 beneath the latter; a thin scopula 
beneath the tarsi and perhaps a small portion of the metatarsi; tarsal claws 2, with a compact claw- 
tuft beneath, and underneath the tuft is a compact group of short dark (nearly black) spines at the 
extremity of a kind of corneous spur or claw-joint. 
Falces strong, conical, somewhat tumid, and prominent in front. 
Palpi moderately long; digital joint long, somewhat clavate, and with a terminal curved dentate claw. 
Mazille short, rather broad, slightly divergent, straight, profile of the inner margin curved, rather obliquely 
truncated at their extremity on the outer side; the inner corner furnished with a strong tuft of hairs. 
Labium short, about half the length of the maxilla, broader than long, rounded at the apex. 
Sternum heart-shaped, longer than broad. 
Abdomen cylindric-oval ; connecting-pedicle covered with a semi coriaceous plate continuous with and including 
that surrounding the genital aperture and the spiracular organs. These last are four, two in the normal 
position and one near (on each side) in front of and a little outside of the other. Spinners short, strong 
compact, the inferior pair very slightly the longest.
