1875. NEW SPECIES OF ERIGONE. 397 
equidistant from each other, the hind centrals being each placed im- 
mediately in front of a round shining pale-coloured tubercle ; those 
of each lateral pair have a round shining tubercle behind them, they 
are contiguous to each other, and obliquely placed ; and from behind 
each of these pairs a longitudinal narrow indentation, fringed with a 
row of bristly hairs, runs backwards and obliquely upwards towards 
the hinder part of the occiput; the eyes of the fore central pair are 
smallest of the eight, near together, but not contiguous to each other, 
and each is separated from the fore lateral eye nearest to it by nearly 
the diameter of the latter. 
The Jegs are moderate in length and strength; their relative 
lengths appear to be 4, 1, 2, 3; they are of a pale dull yellow colour, 
furnished with hairs and one or two fine black spines. 
The palpi are short and similar in colour to the legs, except the 
digital joint, which is suffused with brown; the cubital and radial 
joints are very short; the latter is a little roundly produced at the 
fore extremity on its outer side, where it has a not very large pointed 
apophysis ; the digital joint is very large, and has a strong lobe to- 
wards the fore extremity on the outer side; the palpal organs are 
well developed and complex, a strong black tapering spine issues 
from their midst, and curving round inwards, almost encircles their 
fore extremity, and within its curve is a smaller spine coiled in a cir- 
cular form. 
The falces are rather paler in colour than the cephalothorax ; they 
are tolerably long and strong, a little rounded in their profile-line, 
and divergent towards their extremities when looked at from the front ; 
they are furnished with a few minute teeth towards their extremities 
on the inner margin, and close above them three bristles in a single 
row directed downwards. 
The maville are of normal form, similar to the legs in colour, and 
furnished with some long and strong bristles towards their outer sides. 
The dadium is also of normal form, and (with the sternum, which 
is heart-shaped, convex, and bristly) is of a dark brown colour. 
The abdomen is oval, tolerably convex above, and projects but very 
slightly over the base of the cephalothorax ; almost unique hitherto 
among the numerous species of this genus, it has, like the foregoing 
Species, a strong well-defined pattern on its upperside, very nearly 
resembling that of Amaurobius feror (C. Koch); its colours are 
black and dull yellow, tinged (in four examples) with a slight reddish 
hue ; and according as one or the other of these colours prevail, either 
may be described as the ground-colour. In the example now figured 
and described (Plate XLVI. fig 4), the ground-colour of the upper- 
side is black, the fore half has two large yellowish patches on either 
side, followed by a series of slightly oblique spots or blotches of a 
similar colour, arranged in pairs, and diminishing in size as they 
approach the spinners ; the sides are black, divided by an indistinct 
oblique yellowish gap ; and the underside is dull yellowish, the central 
longitudinal line being clouded with a dusky hue. When the yellow 
prevails, the black forms a central longitudinal bar, from the hinder 
half of which a series of several oblique lateral bars issue on either
