with a small, pointed, black, circularly curved spine toAvards 

 their fore extremity. 



The cephalothorax has three long fine bristles directed for- 

 wards on either side of the upper part of the caput, indicating 

 the position of the exterior eyes of the first row, and of the eyes 

 of the second and third rows. 



The sternum is long and narrow oval in shape, with a strong 

 curved indentation on either side towards the anterior extre- 

 mity, and the hinder extremity much produced. 



Maxilla? long, enlarged at their extremities, which are a 

 little divergent. Labium oblong ; sides and apex emarginate ; 

 length about two-thirds that of maxilla?. 



The adult female only differed from the male in the palpi 

 and falces ; these latter are no longer than the length of the 

 ocular region of caput, and more approaching a vertical posi- 

 tion ; the digital and radial joints of the palpi form one long, 

 oval, flattened piece. 



Genus Eresus (Walck.). 

 Eresus bicolor, n. sp. 



<$ . Adult. Length 3| lines. 



Cephalothorax broad oval, rather depressed behind ; caput 

 much elevated and rounded at its summit ; fore margin, when 

 looked at from above, squarely truncate. Excepting two tri- 

 angular patches in front, which enclose the four central and 

 the two front lateral eyes, the caput is thickly clothed with 

 pure-white hairs ; these patches, as well as the thorax, are 

 jet-black, the latter broadly margined with pure-white hairs 

 also. 



Eyes not very unequal in size, forming a small square within 

 a large one ; the posterior side of the large square formed by 

 the four outer eyes is shorter than its anterior side ; but of the 

 inner square the anterior side is the shortest. 



Legs long, those of first pair very strong, and much the 

 longest of the eight ; relative length 1, 4, 2, 3 ; femora of first 

 pair black ; tibia? nearly so, and both furnished with black 

 hairs ; the rest of the joints are of a dark reddish brown, some 

 of them being broadly annulated with a paler hue. The genual 

 joints, extremities of femora, and fore half and extremities of 

 tarsi thickly furnished with pure-white hairs ; the two hinder 

 pairs have all the joints more or less annulated with bands of 

 white hairs, the alternate spaces being reddish brown varying 

 to black. 



Palpi short, moderately strong, of a deep reddish brown- 

 black ; cubital joints furnished with white hairs ; digital joints
