DESCRIPTIONS OF Two or THE SPIDERS IN THE FOREGOING 



LIST. 



Clubiona facilis, sp. nov., PI. A, Figs. 1, 2, 3, p. 50. 



Adult female, length rather over 5 lines. 



In general appearance and colour, this fine species is much 

 like Clubiona holosericea, Degeer., but is rather larger ; 

 the Cephalothorax is but very slightly constricted on the 

 lateral margins at the junction of the caput and thorax, 

 and the profile line forms a continuous curve ; it is of a reddish 

 yellow-brown hue deepening into a rich red-brown on the 

 caput, and furnished with a short silky grey pubescens in parts, 

 probably in a more perfect example over the greater part. The 

 legs are dull yellow above, whitish yellow underneath, furnished 

 normally with spines, and with a dense scopula of dark hairs 

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

 legs. 



The Eyes are small, and in the normal position. Those 

 of the posterior row are in very nearly a straight line, and 

 separated by nearly equal intervals, that between the two 

 central eyes being a little greater than between each of them 

 and the laterals. 



The Falces are massive, prominent, and of a deep shining 

 dark red-brown colour. 



The Abdomen is of a dull yellowish colour, apparently 

 furnished thinly with greyish pubescens and some fine 

 black hairs ; and a dark blackish pattern is traceable on the 

 upper side, consisting of some lateral lines, and several trans- 

 verse angular bars, or chevrons, on the hinder half in the 

 median line ; the foremost of these bars traverses the whole 

 of the width of the abdomen. On the fore part of the abdomen 

 there are also traces of a central longitudinal dark marking 

 and a lateral one on each side as well. The under side is 

 whitish yellow. The spinners are cylindrical, those of the 

 inferior pair are much longest and largest, they are of a yellow 

 hue, the superior pair whitish. The genital aperture is large 

 and of a very distinctive form.
