CLUBIONA.

is truncated obliquely on the inner side; the lip is somewhat oval, but truncated at the apex; 
the sternum is of a narrow oval form, with distinct eminences opposite to the legs. These 
parts are of a brownish-black hue, the middle of the sternum and the extremities of the 
maxillse and lip having a reddish tinge. The eyes form two transverse rows on the anterior 
part of the cephalo-thorax; the posterior row is the longer, and the interval between the 
intermediate eyes is greater than the space which separates them from the lateral ones of the 
same row; the eyes of the anterior row are situated very near to the frontal margin. The 
legs and palpi are robust, and are provided with hairs and sessile spines; they are of a dark, 
reddish-brown colour, with longitudinal lines of a deeper and lighter shade on the upper side ; 
the fourth pair of legs is the longest, then the second, and the third pair is the shortest; each 
tarsus is terminated by two curved, pectinated claws, below which there is a small scopula. 
The abdomen is of an oblong-oviform figure, projecting a little over the base of the cephalo- 
thorax; it is of a very dark-brown colour, and is covered with yellowish-white hairs, 
approaching to gray on the under side; the spinners are rather prominent, and the branchial 
opercula are large, and of a yellow hue. 
The male is smaller than the female, and its cephalo-thorax, legs, and palpi are paler; 
its falces also are longer and more prominent. The cubital and radial joints of the palpi are 
short; the latter projects two apophyses from its extremity, on the outer side; the anterior 
one, w’hich is the larger, is obtuse, and the posterior one terminates in a point; the digital 
joint is oval, convex and hairy externally, concave within, comprising the palpal organs; 
they are highly developed, prominent, not complicated in structure, and of a very dark- 
brown colour. 
Crevices in stone walls and the under side of fallen leaves are the usual haunts of 
Clubiona epimelas, which is found, though rarely, in the wooded parts of Denbighshire and 
Caernarvonshire. The male has the palpal organs completely developed in May, and in June 
the female constructs a plano-convex cocoon of white silk of a very fine texture, measuring 
to tlis of an inch in diameter, in which she deposits about 154 spherical eggs of a pale-yellow 
colour, not agglutinated together. The cocoon is attached by its plane surface to the under 
side of a stone or leaf, and is inclosed in a sac of white silk, which also comprises the female.

Length of the female, ^ths of an inch. 
The legs are hairy, spiny, and of a pale hue, with the exception of the last joints of the 
tibiae and tarsi, which are jet-black underneath. The cephalo-thorax is oval, elongate, and of 
a pale, yellowish-brown colour, with dark margins; the part including the eyes has a reddish 
tint, and an abbreviated black line occupies the middle thoracic point; underneath it is 
of a dark, castaneous-brown hue. The abdomen is of an elongate oval form ; the upper part 
has a reddish-brown colour, with four impressed dots near the middle, which form a
