ARANEIDEA. 
27 
The palpi are moderate in length, and similar in colour and armature to the legs ; the 
digital is double the length of the radial joint, and terminates with a weak, curved, black 
claw. 
The falces are of moderate length and strength, straight, perpendicular, and obliquely 
cut away on the inner sides towards the extremity ; their colour is yellow, and they are fur- 
nished with hairs and longish bristles. 
The maxilla are rather strong, moderately long, straight, somewhat rounded at their 
extremities, and similar to the falces in colour. 
The labium is short, rounded at the apex, and of a yellowish-brown colour. 
The abdomen is oval, truncated before, rounded and broadest behind ; it is thinly clothed 
'with hairs of a clay-yellow colour, marked above and on the sides with blackish brown ; these 
markings were very much broken and fragmentary in the example described, but they appear 
to define faintly the ordinary oblong, median, longitudinal marking on the fore half, and some 
angular bars on the hinder half of the upper side, with some oblique lines on the sides. The 
spinners are very short ; the second joints of those of the superior pair are barely perceptible. 
The genital aperture appears as a densely black, glossy patch in the centre of a largish yellow- 
brown, convex area, and is rather densely clothed w r ith bristly hairs, whose points converge 
over the black aperture.

25. — Agroeca flavens, sp. n., PI. II, Pig. 20, ? . 
Adult female : length 3^ lines. 
The whole of the fore part of this spider is of a dull, slightly brownish-yellow colour, 
the labium , however, being dark yellow T -brown with a yellowish apex, and the abdomen of a 
straw-yellow thinly clothed with yellowisli-grey hairs. In form and structure this species 
re semblcs Agroeca debilis ; the normal indentations on the cephalothorax are well marked, and 
°f a deeper hue than the rest, and it is clothed with hairs similar to those on the abdomen. 
The eyes are small, placed in two, nearly straight, transverse rows, and seated on black spots ; 
the front row is considerably the shortest ; those of the hind-central pair are very slightly 
f arther from each other than each is from the hind-lateral eye on its side, and each is separated 
from the fore-central opposite to it by no more than, if quite so much as, the diameter of 
the former ; those of the foremost row are very near to each other, the interval between 
those of the fore-central pair being slightly greater than that which divides each from the 
frre-lateral on its side ; those of each lateral pair are placed very obliquely, and have an 
interval between them of nearly the diameter of the hinder one ; the fore-laterals are the 
hugest of the eight; the height of the clypeus is equal to the diameter of one of the fore- 
Ce ntral eyes. 
The legs are tolerably long and strong, furnished with hairs and rather long, strongish 
s pines ; each tarsus ends with two curved claws, apparently without any denticulations, below 
them being a rather less conspicuous, corneous, yellow-brown prominence than in Agroeca 
debilis , hut furnished with similar upturned bristly hairs ; the relative length of the legs 
a Ppears to he 4, 1, 2, 3 ; the spines on the two first pairs are in two parallel longitudinal rows 
beneath the metatarsal and tibial joints. 
The palpi are moderately long and strong ; the radial and digital joints are yellow-
