118 ARANEIDEA. 
middle of the fore extremity, two wide apart across the middle, and, with these last, two others at the top 
of the posterior slope form nearly a square, while the two remaining ones are lower down towards the 
spinners, but placed much wider apart ; the anterior sides of all these eminences, excepting that at the 
fore extremity, are black. The spinners are short, 2-jointed, and compact. The genital aperture is 
small, but of very characteristic form. 
It is most probable that the colours and markings above given of the abdomen would be found in other 
specimens to vary considerably, as the type example appears to be in a faded, washed-out condition, from 
the action of the spirit in which it is preserved. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
PHILODROMUS, Walckenaer. 
Philodromus maculatipes, sp. n. 
Adult male, length 3 lines. 
Cephalothorax of equal length and breadth, and, generally, of normal form, round behind, obtusely pointed 
before on the upperside in the ocular region, squarely truncate below at the clypeus, which last is promi- 
nent and its extent equal to rather more than half that of the facial space; the clypeus is furnished with 
strong curved bristles, as also are the sides of the ocular area; the lateral marginal compressions at the 
caput are strong. Its colour is yellow-brown, slightly tinged with reddish ; the sides are dark brown, with 
a radiate appearance, the radiations converging at the thoracic junction ; and at the posterior extremity 
of the caput is a strong V-shaped dark brown marking, whose point is directed backwards—viewed under 
a lens this marking is seen to be composed of numerous small black spots. . 
The eyes are small, subequal, seated on black tuberculate spots. They form, perhaps, a less crescent-shaped 
than subtriangular area; each lateral pair forming with the fore-central eye on its side a very nearly 
straight line. The eyes of the hind-central pair are much further from each other than each is from the 
hind-lateral eye on its side. 
The legs are long, rather slender ; those of the second pair are longest, next those of the first pair, which are, 
however, scarcely longer than the fourth, and (probably) the third pair are shortest, but in the only 
examples seen of this spider both of the third pair are wanting. They are (except the tarsi) armed with 
rather fine spines and hairs; their colour is pale brownish-yellow, speckled with small irregular black 
spots. The tarsi and a portion of the metatarsi of the first and second pairs have a thin scopula beneath 
them, and all have a claw-tuft. 
The pa/pi are short, similar to the legs in colour and armature ; the cubital and radial joints are nearly equal 
in length, the latter perhaps is slightly the longer and has, at its extremity on the outer side, a short, taper- 
ing, obtusely pointed dark-coloured apophysis, beneath which is another paler one of the same length but 
stronger. The digital joint is not very large, narrow-oval in form, with some long prominent curved 
spines at its base above, and at its extremity are several short, black ones of a denticulate nature. The 
palpal organs are simple, consisting of an oval lobe, round the anterior extremity of which is a strongish 
curved sharp-pointed spine whose point is directed rather downwards on the outer side. 
The falces are moderately strong, slightly longer than the facial space, vertical, conical, furnished with strong, 
prominent spines in front, and of a dark brown colour. The fangs are short and strong. 
The mazille are long, rounded at the extremity, inclined towards the labiwm, which is about two-thirds the 
length of the maxille, short-oblong in form, rounded at the apex, and rather constricted laterally towards 
the base. The maxilla are similar to the legs in colour, but rather darker towards the extremities; the 
labium is dark yellow-brown. 
The sternum is broad, heart-shaped, and of a brownish-yellow hue. 
The abdomen is of a somewhat oblong-oval form, broadest behind; the fore extremity is distinctly cleft or 
emarginate in the middle. It is clothed with hairs, and is of a general dull blackish colour mixed with dull 
whitish ; on the fore part of the upperside is a longitudinal central deep black-brown stripe, indistinctly 
visible, followed towards the spinners by some fine dull whitish angular lines or chevrons. The spinners 
are short, rather compact, and of a dark brown hue.
