LINYPHIIDiE. 
The eyes are seated on black spots; the four intermediate ones form a trapezoid whose 
anterior side is the shortest, and those of each lateral pair are placed obliquely on a tubercle, 
and are nearly contiguous; the anterior eyes of the trapezoid are the smallest of the eight. 
The legs are long, slender, provided with hairs and spines, and of a red colour ; the first pair 
is the longest, then the second, and the third pair is the shortest; each tarsus is terminated 
by three claws; the two superior ones are curved and minutely pectinated, and the inferior 
one is inflected near its base. The palpi are short, and resemble the legs in colour, with the 
exception of the digital joint, which has a dark-brown tint; the radial joint is stronger than 
the cubital, and has some long hairs in front; the digital joint is somewhat oval, with a large 
lobe on the outer side, near its base; it is convex and hairy externally, concave within, 
comprising the palpal organs, which are highly developed, complicated in structure, with a 
broad, compressed, curved process projecting nearly at right angles from their base, on the 
outer side, and are of a dark, reddish-brown colour. The abdomen is oviform, very sparingly 
supplied with short hairs, convex above, projecting over the base of the cephalo-thorax; it is 
of a yellowish-brown colour on the upper part and sides, a series of black, angular lines, 
whose indistinct vertices are directed forwards, extending along the middle of the former ; 
the extremities of the anterior lines of the series are much the most strongly marked, and a 
small, yellowish-white spot occurs immediately above the spinners; the under part is of a pale 
brown colour. 
Mr. F. Walker took this species in May, 1850, among juniper bushes at Southgate.

The four intermediate eyes form a trapezoid whose anterior side is the shortest, and 
those of each lateral pair are seated obliquely on a small tubercle, and are contiguous; the 
posterior eyes of the trapezoid are the largest, and the anterior ones are much the smallest of 
the eight. The cephalo-thorax is oval, convex, glossy, with an indentation in the medial line, 
and is of a dark-brown colour, approaching to black. The falces are long, powerful, armed 
with teeth on the inner surface, divergent at the extremity, of a deep-brown colour tinged 
with red, and incline towards the sternum, which is heart-shaped, and of a brownish-black 
hue. The maxillae are strong, and have the exterior angle, at their extremity, curvilinear; 
they resemble the falces in colour, and incline a little towmrds the lip, which is semicircular, 
prominent at the apex, and has a brownish-black tint. The legs are long, slender, provided
