Length of the female, Jth of an inch; length of the cephalo-thorax, |th, breadth, T ' s th;

the third pair, 1 th. 
The cephalo-thorax is convex, hairy, compressed before, truncated in front, and rounded 
on the sides, which are marked with furrows converging towards the middle; its colour is 
light-gray, intermixed with yellowish-brown and dark-brown 5 the latter hue forms a medial 
band, whose anterior extremity is ramified in the region of the eyes, and several oblique rays 
and spots on the sides; the margins have a yellowish-white tint, which extends, in front, to 
the anterior row of eyes. The falces are small, conical, vertical, and of a dark-brown hue, 
with a conspicuous, yellowish-white spot in front. The maxillae are convex near the base, and 
inclined towards the lip, which is triangular and rounded at the apex. These parts are of a 
dark-brown colour, tinged with red, the lip being the darkest. The sternum is heart-shaped, 
and of a yellowish-brown hue. The eyes are disposed on the anterior part of the cephalo- 
thorax, in two transverse, curved rows, forming a crescent whose convex side is directed 
forwards; the lateral eyes of both rows are seated on minute tubercles, those of the posterior 
row being the largest, and the two intermediate ones of the anterior row the smallest of the 
eight. The legs are long, provided with hairs and sessile spines, and of a pale, reddish-brown 
colour, with black spots and annuli, abroad, black streak extending along the anterior side of 
the femora of the first pair; the second pair is the longest, then the first, and the fourth pair 
is slightly longei than the third ; each tarsus is terminated by two curved, minutely pectinated 
claws, below which there is a small scopula. The palpi resemble the legs in colour, and have 
a broad, longitudinal, black streak on the anterior side of the humerus. The abdomen is 
broader in the posterior than in the anterior region, but is pointed at the spinners ; it is hairy, 
somewhat convex above, and the anterior extremity, which is notched in the middle, projects 
over the base of the cephalo-thorax; the upper part is of a yellowish-gray colour, tinged with 
green, a few curved, black lines forming very obtuse angles, whose vertices are directed 
forwards, and whose convex sides are turned towards each other, occurring in the posterior 
region; the sides are mottled with black, and on each there are two oblique streaks of the 
same hue, bordered posteriorly with long white hairs; the under part has a yellow-brown hue, 
four dark-brown lines extending from the anterior extremity to the spinners, where they 
meet; and the colour of the branchial opercula is brown. 
Philodromus pallidus has numerous compound hairs on various parts of its body and 
limbs.
