76. DI^EA SUBDOLA, sp. n. 



Adult male : length rather more than 1^ lines. 



The cephalothorax is round-oval behind, broad and truncated in front, longer than it is 

 broad, and the lateral constrictions of the caput are slight; its colour is dull brownish 

 orange-yellow, the hinder part of the caput, and some short lateral converging stripes, being 

 pale yellow ; its surface is smooth and glossy, but covered very thinly with long, nearly erect, 

 curved black bristles ; the height of the clypeus is a little less than half that of the facial 

 space. 



The eyes are seated on rather strong, greenish-white tubercles in the form of a crescent ; 

 they do not differ greatly in size ; the fore-laterals are, however, distinctly the largest of the 

 eight, and the tubercles on which they are seated are also the largest ; the other eyes differ 

 very slightly in size ; the fore-centrals, however, appear to be rather larger than those of the 

 hinder row : the front row being the shorter and more curved, a more strongly crescent 

 form than usual is given to the ocular area, and the interval between the eyes of each lateral 

 pair is consequently less than that between the fore and hind-central pairs : the intervals 

 between the eyes of the hinder row are as nearly as possible equal, while that between the 

 fore-centrals is distinctly greater than that between each and the fore-central on its side. The 

 four central eyes from a quadrangular figure whose longitudinal is slightly greater than its 

 transverse diameter at the hinder part, and its fore-side the shortest. 



The legs are not very slender; those of the first and second pairs are long, the latter 

 slightly the longer ; the third pair is the shortest, but that and the fourth pair, in propor- 

 tion to the first and second, are not so short as usual ; they are very nearly of the same colour 

 as the cephalothorax, and are furnished with bristles and longish slender spines. 



The palpi are short and similar to the legs in colour ; the radial and cubital joints are 

 short and of nearly equal length ; the former is, if anything, rather the shorter, hut a little 

 stronger ; it has a few strong spine-like bristles, and its extremity on the outer side is pro- 

 longed into a longish projection, bent a little downwards and backwards, rather broadest near 

 its extremity, which is rather bifid or slightly furcate ; and there is another strong, curved 

 obtusely-pointed process beneath the joint. The digital joint is large, broad, and rounded 

 behind, pointed in front, and is somewhat angularly prominent on the outer margin ; the pal- 

 pal organs are simple but encircled by a long, strongish, black spine which issues from their 

 base on the inner side. 



The y 'aloes are neither long nor very strong ; they are nearly perpendicular, and similar 

 in colour to the cephalothorax ; the maxilia and labium are of the ordinary form and rather 

 duller and paler thanthe falces. 



The sternum is heart-shaped and of a brightish yellow colo ur. 



The abdomen is round and broadest behind, narrower and mo re pointed hefore ; it is 

 of a dull brownish-yellow colour, marked with cretaceous white spots on either side of the 

 upper part, defining indistinctly the normal dentated central band so conspicuous generally 

 in xysticus ; there are also several deep red-brown spots on each side, and a large patch suf- 

 fused with red-brown at the hinder extremity surrounding the spinners, but chiefly placed on 

 each side of them ; the under side is paler than the upper ; the upper side is furnished with 

 a few scattered, long, strong bristle ; and an oblong-oval patch between the spiracular plates 

 is similar in colour to the sternum. It is probable that there may be, in a series of examples,
