AGELENA.

and marked with farrows converging towards an indentation in the middle, and a row of long 
hairs, directed forwards, extends along the medial line ; the falces are strong, conical, and 
vertical; the maxillae are short, convex at the base, round at the extremity, and slightly 
inclined towards the lip, which is nearly quadrate, being rather broader at the base than at 
the extremity; the sternum is heart-shaped. These parts are glossy, and, with the legs and 
palpi, are of a dark-brown colour, the margins of the cephalo-thorax and the base of the 
lip being much the darkest. Each tarsus is terminated by two curved, pectinated claws. 
The lateral eyes are the largest, and the intermediate ones of the anterior row are the smallest 
of the eight, 'the abdomen is soot-coloured, short, thickly covered with hairs, rather broader 
at the posterior than at the anterior extremity, convex above, and projects a little over the 
base of the cephalo-thorax; the colour of the spinners is brown; they are disposed in a 
transverse row immediately below the anus, and the exterior ones, which are much longer 
than the rest, and triarticulate, have the spinning-tubes distributed on the inferior surface of 
the terminal joint; the sexual organs are prominent, and of a dark, reddish-brown hue; and 
the branchial opercula have a pale-yellow tint. 
The male is smaller than the female, but it does not differ from her in colour. The 
cubital and ladial joints of its palpi are short; the former, which is the larger, has a fine, 
prominent process on the outer side, near the upper part, which is curved upwards at its 
extremity, and the latter is terminated, on the under side, by a pointed apophysis curved 
outwards; the digital joint is oval, convex and hairy externally, concave within, comprising 
the palpal organs ; they are highly developed, not very complicated in structure, with a 
pointed, corneous process, which originates near the middle of the outer side, and is curved 
upwards ; their colour is dark-brown. The convex sides of the digital joints are directed 
outwards. 
About midsummer, this species, which, notwithstanding its close connexion with the 
Agelenm , M. Walckenaer has placed in the genus Argus (see the synonyma), may be seen in 
considerable numbers running on the ground, and on rails and gates, in pastures near 
Llanrwst. The palpal organs of the male are fully developed in May.
