SOME NEW ARANEID.'E FROM 1'HE COUNTS OF CUMBERLAND. 59 



Genus Uloboros, Latr. 

 Uloborus congregabilis, sp. nov. 

 (Figs, i and 2.) 

 Male. Cephalothorax. 1.4 mm. long, 1.1 mm. broad; abdomen, 1.8 mm. long, 1.1 mm. broad 

 (fig. D- 



Cepthalothorax. — Ovate, hairy. Pars cephalica obtuse, arched, yellowish down the middle, sides 

 dark brown ; ocular area broader than long; clypeus, deep. Pars thoracica broad, convex, yellow, 

 but having two sub-lateral curved, longitudinal brown bars ; median fovea deep ; marginal band broad, 

 dark brown. Eyes. — Arranged in two recurved rows of four each ; the two median eyes of the front 

 row are the largest of the entire series ; they are seated closely together, are very prominent, and 

 are poised upon the summit of a tubercular eminence ; the median eyes of the posterior row are 

 separated from each other by a space equal to about twice their individual diameter, while the lateral 

 eyes of this row are each removed from its median neighbour by a space equal to once their individual 

 diameter ; anterior lateral eyes are as large as those of the posterior row. Legs. — The first pair are the 

 longest and stoutest ; the femur is dark brown with a yellowish annulation, patella dark brown, tibia 

 dark brown with pale yellow annulation. metatarsus and tarsus yellow ; all the other legs are, with 

 the exception of their tarsi (which are yellow), dark brown with yellow annulations ; each limb is 

 clothed with golden pile, and armed with short, stifi spines ; relative lengths : 1,4,2,3. Palpi. — Short, 

 dark brown, clothed with yellow pile; genital bulb large, complicated, and clothed with long golden 

 hairs or bristles. Falces. — Robust, dark brown, hairy. Maxilla: and Labium. —Dark brown ; normal. 

 Sternum. — Elongate, arched, subparallel, dark brown, hairy, attenuated and acuminate posteriorly, 

 and terminating between fourth pair of coxa'. Abdomen. — Somewhat cylindrical, highest towards the 

 front, overhanging base of cephalothorax, dark brown with greyish patches ; at its highest point there 

 are two tubercles, and at the rear of these, two others. Spinnerets and cribellum normal. 



Female. Cephalothorax, 1.9 mm. long, 1.3 mm. broad ; abdomen, from petiolus to posterior angle 

 2.4 mm., from summit of anterior tubercle to spinnerets 4.5 mm., breadth 2.5 mm. (fig. 2). 



Cephalothorax. — Ovate, hairy. Pars cephalica obtuse, arched, dark brown ; ocular area and 

 clypeus normal. Pars thoracica arched, dark brown ; median fovea deep ; marginal band broad, yellow, 

 Eyes. — As in Male. Legs. — With the exception of tarsi (which are yellow), dark brown, with pale yellow 

 annulations ; first pair much the longest and strongest ; each limb clothed with golden hairs, and 

 armed with short stiff spines; calamistrum. normal: relative lengths: I, 2. 4, 3. Palpi. — Short, 

 dark brown, annulated with yellow, hairy. Falces. — Dark brown, hairy. Maxillrz and Labium. — 

 Dark brown. Sternum. — As in Male. Abdomen. — Gibbous, overhanging base of cephalothorax, dark 

 brown, mottled with grey, and having a rather large, whitish reticulated patch at anterior extremity, a 

 large yellowish spot on each side near the middle (in some examples), and a broad concolorous bar 

 running down the posterior angle towards the spinnerets. At the summit there is a large and promi- 

 nent tubercular projection, and this is bifurcated at the apex ; near the base of this projection there 

 are two small tubercles connected by a distinct ridge. Epigynum. — This consists of two small tubercles 

 widely separated from each other ; at the summit of each tubercle there is a large elliptical pit ; each 

 of these is placed obliquely with its apex directed towards that of its neighbour. Spinnerets and Cri- 

 bellum. — Normal. 



Hab. — Parramatta, January 11, 191 5. 



I am indebted to Mr. McCulloch for an excellent series of this interesting species, examples of which 

 he collected both in the field and in buildings. Considerable variation in colour and scheme of orna- 

 mentation is noticeable in both sexes. At first I was inclined to regard this species as U. variabilis. 

 Keys. From the latter, however, it differs in size, form of abdomen, and the epigynum. 2 If the student
