1875. | NEW SPECIES OF ERIGONE. 201 
aperture is characteristic, though somewhat resembling that of several 
others of this group, nearly allied to each other. 
A single adult example of each sex was received in 1872 from M. 
Eugéne Simon, by whom they were (with others of the same species) 
captured at Sappey, in France; an adult male of the same species, 
but darker and more richly coloured, had been previously received 
from M. Simon, from the neighbourhood of Paris, but was at the 
time mistaken for EZ. monoceros. 
ERIGONE NIGROLIMBATA, sp. n. (Plate XXVIII. fig. 10.) 
Adult male, length rather less than 1 line. 
The whole of this exceedingly remarkable Spider is of a pale yel- 
low colour, the cephalothorax and legs being rather the clearest and 
brightest, the former margined laterally with black. The caput is 
greatly elevated, the upper portion being roundish oviform and 
directed backwards ; the part occupied by the fore central pair of 
eyes is prominent ; and the height of the clypeus exceeds half that 
of the facial space ; a strong longitudinal indentation or excavation 
on each side divides the upper part of the caput from the lower ; the 
upper part is furnished with a few fine pale hairs. 
The eyes are very unusually placed; those of the hind central 
pair, instead of being placed on or near the summit of the elevated 
oviform portion, are placed at its lower part, one on each side 
immediately above and behind the hind lateral eye, and almost con- 
tiguous with it; the eyes of each lateral pair, together with the 
hind central one on its side, form a short curved line on each side of 
the caput; those of the fore central pair are the highest up of all, 
instead of being, as in most other species, the lowest. 
The J/egs are slender, moderate in length, their relative length 
(apparently) 4, 1, 2,3; they are furnished with hairs and a few 
prominent black slender spines and bristles, those on the two hinder 
pairs being the most conspicuous ; whereas in the adult female those on 
the two foremost pairs are strongest, particularly a row on the inner 
side of each of the tibial joints, which are long, strong, and very 
similar to those on the corresponding legs of E. sundevallii (Westr.). 
The palpi are moderate in length and strength; the cubital joint 
is longer than the radial ; the latter is prominently pointed beneath at 
its fore extremity, and has an almost perpendicularly erect apophysis 
springing from near the fore part of its upperside; this apophysis 
appeared to be nearly or about half the length of the joint, and is 
truncate at its extremity, which is rather broader than the middle 
portion: the digital joint is oval, produced at its hinder extremity 
into a long, strong, curved, corneous apophysis, terminating in a 
tapering, twisted, or sinuous, sharp, filiform spine, whose point is 
directed outwards: the palpal organs are highly developed and 
complex; among other corneous processes a somewhat sinuously 
curved, black, filiform spine is connected with them at their fore 
part on the underside. 
The falces are small, nearly perpendicular, and armed with a few 
minute teeth near their inner extremities.
