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, hlack 

 claw. 



Thefalces 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 labimn 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 with bristly hairs, whose points converge 

 over the black aperture.

25. AGIIOECA FLAVENS, sp. n., PL II, Fig. 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-brown with a yellowish apex, and the abdomen of a 

 straw-yellow thinly clothed with yellowish- grey hairs. In form and structure this species 

 resembles Agroeca debilis ; the normal indentations on the ceplialothorax are well marked, and 

 of 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 

 farther 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 

 fore-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 

 largest of the eight ; the height of the clypaus is equal to the diameter of one of the fore- 

 central eyes. 



The legs are tolerably long and strong, furnished with hairs and rather long, strongish 

 spines ; each tarsus ends with two curved claws, apparently without any denticulations, below 

 them being a rather less conspicuous, corneous, yellow-brown prominence than in Agrdeca 

 debilis, but furnished with similar upturned bristly hairs ; the relative length of the legs 

 appears to be 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-
