larger, and the digital joint is of an oblong oval form, convex and hairy externally, and concave 
within, at the base; this concavity comprises the palpal organs, which are moderately 
developed, rather complicated in structure, with a minute, curved, prominent process on the 
outer side, having immediately before it a small, semi-transparent membrane, and are of a 
brownish-black hue, with parts of a pale, yellowish-brown colour intermixed. The band ex¬ 
tending along the middle of the abdomen, the oblong mark comprised in its anterior part, and 
the series of obtusely angular lines occupying the space between that mark and the spinners, 
are much paler than in the female ; and the under part of the abdomen is of a yellowish-gray 
colour. 
This spider frequents commons and old pastures. The palpal organs of the male are 
fully developed in autumn.

breadth of the abdomen, ith; length of a posterior leg, i; length of a leg of the third 
pair, §ths. 
The cephalo-thorax is large, hairy, and marked with slight furrows on the sides, which 
converge towards a narrow indentation in the medial line ; it is of a dark-brown colour, with 
a broad, yellowish-brown band extending along the middle, and an obscure one of the same 
hue above each lateral margin. The falces are powerful, conical, and armed with a few teeth 
on the inner surface; their colour is dark-brown, faintly tinged with red near the base, in front. 
The maxillae have a reddish-brown hue. The colour of the lip is dark-brown, with the 
exception of the extremity, which has a reddish-brown tint. The sternum is heart-shaped, 
glossy, and has a brownish-black hue. The legs are robust, and of a reddish-brown hue, 
with brownish-black spots and streaks on the thighs ; and the colour of the palpi resembles 
that of the legs. The abdomen is oviform, hairy, convex above, projecting over the base of 
the cephalo-thorax; a broad, yellowish-brown band, which tapers to the spinners, occupies 
the middle of the upper part; anteriorly it comprises an oblong oval mark of a deeper shade, 
whose margins are blackish ; this mark extends nearly half the length of the abdomen, and 
terminates in a point; the yellowish-brown band has a black border, broken into spots 
posteriorly, which spots form, with smaller confluent ones of the same hue, oblique lines 
extending down the sides, the ground-colour of which is yellowish-brown ; the under part also 
has a yellowish-brown hue, and is marked with three obscure, longitudinal, dark-brown bands ; 
the colour of the branchial opercula is brown, the inner margin having a tinge of red ; and 
the sexual organs, which have a dark, reddish-brown hue, are bisected longitudinally by a 
septum. Some individuals have the posterior half of the yellowish-brown abdominal band
