442 Mr. J. Blackwall on new Species of Spiders. 



with a dark-brown line on each side of the middle of the upper 

 part, extending from the anterior extremity more than a third 

 of its length ; between these lines and the spinners, and also on 

 the sides and under part, there are numerous dark-brown spots 

 and streaks, those on the under part being the most minute; 

 the sexual organs are moderately developed and of a red-brown 

 colour. 



The male is smaller, slenderer, much darker-coloured than 

 the female, and its abdomen is densely covered with silky hairs. 

 The cubital and radial joints of its palpi are short ; the former 

 is gibbous at its extremity on the outer side, and the latter pro- 

 jects an obtuse apophysis from its extremity on the outer side : 

 the digital joint has a reddish-brown hue; it is convex and hairy 

 externally, concave within, comprising the palpal organs, which 

 are well developed, rather complex in structure, with a filiform 

 spine curved round their base, inner side, and extremity, and a 

 curved process, whose black point is in contact with some pro- 

 minent semitransparent membrane, at their termination; the 

 colour of these organs is red-brown. 



In spring and summer this species may be seen running 

 among fallen withered leaves in the wood sabout Hendre House 

 and Oakland.

Length of the female J^ths of an inch ; length of the cephalo- 

 thorax £th, breadth y^th; breadth of the abdomen y^th; 

 length of a posterior leg grd ; length of a leg of the third pair 



The legs are moderately long and robust, provided with hairs 

 and a few spines, and of a yellow-red colour, with the exception 

 of the coxfe and femora, which have a brown-black hue faintly 

 tinged with dull yellow ; the fourth pair is the longest, then the 

 first, and the third pair is the shortest ; each tarsus is terminated 

 by two curved, pectinated claws, and the inferior surface of the 

 metatarsi and tarsi of the first and second pairs, and of the tarsi 

 of the third and fourth pairs, is sparingly supplied with hair- 

 like papillse. The cephalothorax is short, glossy, somewhat 

 compressed before, and rounded on the sides, which are marked 

 with furrows converging towards a narrow indentation in the 

 medial line ; the sternum is broad, flat, glossy, and heart-shaped. 

 These parts are of a brown-black colour. The falces are power-
