The male is rather smaller and darker coloured than the female, and its legs are longer,
a leg of the second pair measuring half an inch. The cubital and radial joints of the palpi are
short; the latter projects a pointed apophysis from- its extremity, on the outer side, and a
shorter and more obtuse one, having two conical protuberances near its base, from the under
side; the digital joint is oval, convex and hairy externally, concave within, comprising the
palpal organs, which are moderately developed, with a curved, spine-like process on the
inner side, and are of a .dark, red-brown colour.
Philodromus cespilicolis is found among heath, gorse, and juniper bushes, in the vicinity
of woods in Lancashire, Berwickshire, and the west of Denbighshire. In July the female
spins a cell of compact, white silk among leaves growing near the extremities of the stems of
shrubs, curving them about it and retaining them in that position by means of silken lines.
This cell she occupies, and usually constructs in it two lenticular cocoons, of white silk, of a
delicate texture, depositing in each from 40 to 100 spherical eggs, of a pale-yellow colour.
The cocoons frequently differ considerably in size, the larger one measuring about one fourth
of an inch in diameter.

The cephalo-thorax is short, broad, convex, slightly compressed before and rounded on
the sides; the falces are small, conical, and vertical; the maxillae are gibbous near the base;
the lip is triangular; and the sternum is heart-shaped; the legs are long, slender, and provided
with hairs and spines; the second pair is the longest, then the first, and the fourth
pair is the shortest.. These parts are of a red-brown colour, freckled with minute spots of a
deeper hue. Each tarsus is terminated by two curved, pectinated claws, below which there
is a small scopula. The palpi are short, and resemble the legs in colour; the radial joint is
smaller than the cubital, and projects a large and somewhat pointed apophysis from its
extremity, on the outer side; the digital joint is of an irregular, oval figure, being convex at
the base and depressed near the middle; it is hairy externally, concave within, comprising
the palpal organs, which are moderately developed and not very complicated in structure;
a long, slender, black spine, prominent at its origin on the inner side, is curved round their
extremity, and they are of a red-brown colour; the concavity of the digital joint does not
extend to its termination, which is compact. The eyes are disposed on yellowish-white spots
at the anterior part of the cephalo-thorax, in the form of a crescent, and the lateral eyes are
seated on small but distinct tubercles. The abdomen is oviform, sparingly clpthed with hairs,
convex above, projecting over the base of the cephalo-thorax; its colour is red-brown, freckled
with minjite spots of a darker hue, the sides being the palest; on the upper part, a series pf
oblique, not very distinct, yellowish-white spots occurs on each side of the medial lin e ; these
series are slightly curved, and, as their extremities meet, they describe an oblong, lanceolate
figure.
A male of Philodromus Clarkii, having the palpal organs completely developed, was taken
at Southgate in June, 1849, and is preserved in Mr. Walker’s cabinet.

The abdomen is oviform, hairy, convex above, and projects a little over the base of the
cephalo-thorax; the upper part is of a yellowish-brown hue, mingled with red-brown and
very dark-brown; a band of the last colour extends from its anterior extremity, along the
middle, nearly half of its length; this band is comprised between two parallel bands of a pale,
yellow-brown hue, and on each side of it there are two dark-brown, circular depressions, the
four describing a small quadrangular figure; about the middle, several oblique, very dark-
brown patches occur, behind which there is a curved, transverse line of the same hue; a
black streak passes upwards from each superior spinner, and the space between them is of u
glossy, yellow-brown colour; the sides have a red-brown hue, blended with brownish-black;
the under part is of a yellowish-white colour, faintly tinged with d,ull-green, the middle being
occupied by a broad, longitudinal, dark-brown band; and the colour of the branchial opercula
is dull-yellow. The cephalo-thorax is short, broad, convex, hairy, slightly compressed before,
and rounded on the sides, which are of a dark-brown colour, mingled with yellow-brown, a
broad band of the latter hue extending along the middle. The falces are conical, vertical,
armed with one or two small teeth on the inner surface, and of a reddish-brown colour. The
maxillae are gibbous at the base, and have a yellowish-brown tint. The lip is triangular and
of a dark-brown hue, being palest at the apex, which is obtuse. The sternum is heart-shaped,
of a yellowish-brown colour, with reddish-brown lateral margins, and is thinly covered with
whitish hairs. The legs are long, provided with hairs and sessile spines, and of a pale,
.reddish-brown hue, which is deepest at the joints; the second pair is the longest, then the
first, and the third pair is rather longer than the fourth; each tarsus is terminated by two
curved, pectinated claws, and below them there is a small scopula. The palpi resemble the
