54 NEW AND BARE BRITISH SPIDERS 



spines of various sizes. Four of these approach the median 

 line of the upper side, three in front and one behind ; below 

 these eight on either side. Beyond these are two more on the 

 front side. 



Female. — Cephalothorax 2"io mm. long, 1*50 mm. wide at 

 the broadest part, 1 mm. wide at the clypeus. Caput convex, 

 perceptibly raised behind the eyes. All the thoracic furrows 

 strongly marked. 



Eyes pretty closely grouped, covering a space 70 mm. wide. 

 Upper medians and fore laterals equal in size, the diameter 

 being one-third longer than that of the fore medians. The 

 latter are nearly in contact. Middle interval of the upper row 

 considerably less than the lateral. 



Falces normal, except that the inner teeth seem to be 

 rather larger than usual in Hilaira, though not so strong as in 

 Phqulothrix. 



Legs. — Tibiae i. and ii. cylindrical, their diameter 2^ times 

 that of the metatarsi. Tibia iv. subclavate ; diameter at the 

 distal end "27 mm., at the base -19 mm. Spines normal but 

 comparatively weak, especially the distal spine of tibia iv. 

 Hairs coarse and bristly. Lengths of joints of first pair — 

 tibia 1*22 mm., metatarsus roo mm., tarsus '55 mm.; of the 

 fourth — tibia 1*20 mm., metatarsus 1*22 mm., tarsus "77 mm. 



Epigyne unusually large, its width being -64 mm. It is 

 raised into a transverse ridge some "37 mm. above the level of 

 the epigaster at its highest point. The backward slope is 

 very steep and almost wholely occupied by the vulvar fovea. 

 The sculpture of the vulva is more elaborate than in any of 

 the allied species, and will be best understood by a reference 

 to the figures. 



Coloration normal of the genus, with the thorax darker 

 than usual and the furrows more strongly marked. In the 

 case of the male the contrast between the dark thorax and the 

 pallid dome of the cephalic tuber is heightened by the differ- 

 ence in the surface of the cuticle, the thorax being thickly
