LINYPHIlDiE. 
trapezoid, which are somewhat wider apart, and are seated on a less prominent protuberance 
of the cephalo-thorax, together with slight modifications in the structure and development of 
the palpal organs of the male, serve, independently of colour, to distinguish it from the 
former, with which it has probably been confounded. Linyphia terricola is common among 
moss growing in woods in many parts of England and Wales; it occurs also in Scotland 
and Ireland, and the sexes arrive at maturity in July and August. 
The length of the male of this species given by M. Koch in the text is incorrect, but the 
line representing it in the plate rectifies the error. 
M. Walckenaer has added Linyphia terricola to the synonyma of his Linyphia bucculenta 
C Hist. Nat. des Insect. Apt.’ t. iv, p. 485), which is a very different species, and is identical 
with the Linyphia socialis of Professor Sundevall, the name Linyphia bucculenta having been 
conferred by the Swedish naturalist on the species denominated Linyphia reticulata by 
M. Walckenaer.

Length of the female, ±th of an inch; length of the cephalo-thorax, „th, breadth, 3 5 th;

pair, gth. 
The cephalo-thorax is oval, convex, glossy, with slight furrows on the sides converging 
towards an indentation in the medial line ; the falces are powerful, conical, nearly vertical, 
divergent at the extremity, and armed with teeth on the inner surface; the maxillae are 
straight, with the exterior angle, at the extremity, curvilinear; the legs and palpi are provided 
with hairs and fine spines. These parts are of a light yellow-brown colour, the legs and 
palpi being rather the palest. The lip is semicircular and prominent at the apex ; and the 
sternum is short, broad, and heart-shaped. These parts are browner than the cephalo- 
thorax, the margins of the sternum being the darkest. The first pair of legs is the longest, 
the second pair rather surpasses the fourth, and the third pair is the shortest; each tarsus is 
terminated by three claws; the two superior ones are curved and slightly pectinated, and the 
inferior one is inflected near its base. The eyes are seated on black spots; the four inter¬ 
mediate ones describe a trapezoid whose anterior side is the shortest, and those of each 
lateral pair are placed obliquely on a small tubercle and are nearly contiguous ; the anterior 
eyes of the trapezoid are the smallest of the eight. The abdomen is oviform, thinly clothed 
with hairs, convex above, and projects over the base of the cephalo-thorax; it is of a dull, 
olive-green colour, with a series of obscure, pale yellowish-brown, oblique streaks on each 
side of the medial line of the upper part, and a band of the same hue extending along each 
side; a large, prominent, red-brown process, connected with the anterior margin of the 
sexual organs, is directed backwards; and the colour of the branchial opercula is pale-
