SECOND YARKAND MISSION. 
76. — Due a subdola, sp. n. 
Adult male : length rather more than If 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, hut 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. 
Th efalces are neither long nor very strong ; they are nearly perpendicular, and similar 
in colour to the cephalothorax ; the maxilice 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 before ; it lb 
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 W1 
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)
