1875. ] NEW SPECIES OF ERIGONE. 329 
The mazille are of a somewhat oblong oval form, inclined (but 
not curved) towards the labium ; they are similar in colour to the 
falces, the extremities, however, being of a whitish hue. 
The /abium is very short and of the ordinary somewhat semi- 
circular form, its colour being darker than that of the maxillz. 
The sternum is similar in colour to the cephalothorax, and clothed 
thinly with longish bristly hairs. 
The abdomen is large, tolerably convex above, and projects well 
over the base of the cephalothorax; it is of a dark yellow-brown 
colour, and thinly clothed with fine hairs; when seen in spirit of 
wine it is finely mottled and marked with yellowish lines. 
This Spider is nearly allied to H. nemorivaga, p. 326, but may be 
easily distinguished on comparison with the figures and description 
of that species. 
The adult female resembles the male in colours and general cha- 
racters ; the clypeus, however, is lower, and the falces have four teeth 
instead of three ; the form of the genital aperture is rather complex 
and defies description, but some idea of it may be obtained from the 
figure given. 
I had some doubt at first whether this Spider were not identical 
with Lrigone paradowa, L. Koch, the radial joint of the male palpus 
being of a very similar form; but I am inclined to believe it to be 
quite distinct. 
Both sexes were received, in January 1874, from M. Simon, by 
whom they have been found in several parts of France. 
ERIGONE FLUCTUANS, Sp. 2. 
Adult male, length 1 line. 
This Spider is very nearly allied to Lrigone subtilis, Cambr. ; it 
may however, be distinguished by several particulars, noticed here. 
The cephalothoraz is of a yellow-brown colour, rather flat, with 
a very slight impression in the profile line, behind the occiput, and 
the hinder slope is short and very gradual; the height of the cly- 
peus, which is vertical and has no transverse impression, is less than 
half that of the facial space. 
The eyes are smaller than those of EZ. sudtilis; those of the 
hinder row are equidistant from each other; if any thing the hind 
centrals may be rather nearer together than each is to the lateral of 
the same row on its side. ; 
The /egs are of a brownish yellow colour, tolerably long, slender, 
and furnished with hairs and a very few short strong bristles or 
very slender spines. 
The palpi are short ; the radial joint is stronger than the cubital, 
and has a small, somewhat tooth-like apophysis at its outer extremity, 
when looked at from the front and rather on the inner side; the 
digital joint is of moderate size, and has a conical prominence at 
its base, with its extremity directed inwards ; the palpal organs are 
complex, but do not present any very large or remarkable processes, 
The falces are strong and produced at the extremities, which are 
strongly divergent, the divergent portions excavated on the inner
