REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 395 
The palpi of the male have the radial and digital joints densely furnished with strong 
black hairs; the digital joint is large, round-oval behind and sharp-pointed at the ex- 
tremity ; the palpal organs are well developed and rather complicated, consisting of 
several corneous processes ; a strong corneous sharpish-pointed projection issues from near 
their base, and stretches obliquely over them, its point terminating near the outer side 
of their extremity; they are also embraced transversely by one or two black filiform 
spines, which issue from their inner side. 
This species is very active, and is abundant on heaths and moors in Dorsetshire, where 
it is adult in June and July. It was supposed by Mr. Blackwall to be his Lycosa exigua, 
from which, however, it is clearly distinct, and may be distinguished at once by the lon- 
gitudinal yellow bands on the cephalothorax; in the Lycosa exigua these are narrow, 
especially the central one, which, narrow throughout, fines off to a sharp point at its fore 
extremity. The sternum also in exigua is of a uniform dark blackish brown, whereas 
in Lycosa congener it has a broad central band or patch of yellowish colour. A close 
examination, also, with a magnifying glass will show the structure of the palpal organs 
to be quite different. The legs also in exigua are much more distinctly and regularly 
marked with dark brown. It is nearly allied also to Lycosa herbigrada (Bl), which 
occurs more locally in the same localities; the latter is, however, adult, generally speak- 
ing, much earlier (in May), and its hoary ground-colour and black markings cannot fail 
to distinguish it at a glance from the present species, even if the structure of the palpal 
organs be not examined. 
LYCOSA FARRENIL n. sp. (Pl. 54. no. 2.) 
Male adult, length 23 lines. 
In general form and appearance this species nearly resembles several other small 
Lycos® indigenous to Britain (Lycosa exigua &e.), but it may at once be distinguished by 
the strong, tumid radial joint of the palpi, as well as by specific marks in colouring &c. 
The cephalothorax is of a dark yellow-brown, with a broad longitudinal deep-brown 
band on either side of the median line, and another narrow one just above the lateral 
margins; the central yellow-brown longitudinal space between the lateral bands is not, 
as in exigua, clearly and evenly defined on its margins; the line is somewhat irregular, 
and broken into by the convergence of lateral lines, which follow the direction of the 
normal grooves and furrows of the thorax; the fore part of the space occupied by the 
eyes is strongly suffused with black; and each of the falces, which are yellow brown in 
colour, has a broadish deep-brown longitudinal band in front; the eyes of the lower row 
are of about equal size, but the two centrals are further from each other than each is 
from the lateral one on its side. The maxillæ are strong, straight, obliquely truncate at 
their extremity on the outer side, and of a pale yellow-brown colour; labium oblong, of 
a deep brown tipped with yellowish. Sternum heart-shaped, and of a deep rich brown 
colour. 
Legs moderately long and strong; relative length 4, 1, 2, 3, the difference between 1, 
2, and 8 being very slight; they are generally of a yellow-brown colour, the femoral and 
general joints being deeply suffused with dark brown, and the tarsi rime mus are
