1875. ] NEW SPECIES OF ERIGONE. 331 
tremity, directed downwards, and below it, on the inner margin, are 
two or three minute ones. 
The mazille are similar in colour to the falces, rather long and 
strong, straight, and inclined towards the labium; on the outer side 
of each are two or three longish bristles springing from minute 
tubercles. 
The Jadium is short and broad, rather pointed at its apex, and 
similar to the maxillee in colour. 
The sternum is of the ordinary heart-shape, tolerably convex, 
furnished with a few bristles, and of a yellow-brown colour. 
The abdomen is short oval, and tolerably convex above; itis clothed 
thinly with hairs, and is of a yellowish brown colour tinged with olive. 
Adult examples of the male were received from M. Simon, by 
whom they were found at Chaville near Paris, and also at Troyes. 
ERIGONE DILUTA, sp. n. (Plate XLIV. fig. 6.) 
Adult male, length 2 of a line. 
The whole of the fore part. of this Spider is of a bright straw or 
pale orange-yellow colour, the sternum, however, being a little 
suffused with sooty brown ; the form of the cephalothorax is ordi- 
nary, the occiput and thoracic junction being on nearly the same 
level, and between them is a very slight depression; the height of 
the clypeus, which projects a very little forwards below, equals half 
that of the facial space. 
The eyes are of tolerable size, rather large for the genus, and do 
not differ very greatly in size; they are seated on black spots in 
the usual position ; the hinder row is the longest and most curved, 
the front row being nearly straight ; the eyes of the hind central 
pair are divided from each other by an eye’s diameter, but are 
further from each other than each is from the hind lateral on its 
side, to which last it is in fact almost contiguous; those of the fore 
central pair are smallest of the eight, dark-coloured, and very incon- 
spicuous, contiguous to each other, and each is removed from the 
fore lateral on its side by but a very small interval; the interval 
between each fore central and the hind central eye on its side is equal 
to that which divides the eyes of the hind central pair. 
The legs are neither very long nor strong; their relative length is 
4, 1, 2, 3, and they are furnished pretty thickly with rather coarse 
hairs and slender bristles. 
The palpi are short and slender ; the cubital and radial joints are 
both very short ; the latter is a little produced at its fore extremity on 
the upperside in a blunt-pointed form, but has no distinct projection 
or apophysis; each of these joints, besides some other hairs, has a 
single tapering black bristle projecting forwards from near the fore 
extremity of its upperside; the digital joint is not large, and its 
form is oval; the palpal organs are well developed but not very com- 
plex, consisting of a smooth oval whitish lobe and several corneous 
spines, one of which, of a pale colour and somewhat slender and 
sinuous form, issues from the base of the palpal organs, and, passing 
over their entire length, projects beyond their fore extremity.
