80 SECOND YARKAND MISSION. 



dentated, pale dull yellowish-brown band slightly spotted with brown. The cephalothorax 

 has a median longitudinal band edged with white hairs like that of O. rectifasciata. 



The eyes are in a similar position to those of that species, but at the same time are rather 

 more separated from each other. 



The legs are rather long, of a dull, darkish yellow-brown colour, armed with spines; 

 and their relative length appears to be 4, 2, 1, 3. 



The/ta?sare similar to the last species in form and size, and are of a dark shining 

 yellow- brown, deeper in hue than the legs. 



The maxilla are yellow-brown, palest at the extremities, and the labium is of the same 

 colour, with a pale apical margin. 



The sternum is yellowish, with a distinct, broadish, yellow-brown marginal border, and 

 is clothed with coarse grey, and a few dark-brown, hairs.

Genus TROCHOSA, C. L. Koch. 



100. TROCHOSA RUBIGINEA, sp. n. 



Adult female : length 4J lines. 



It is not without considerable hesitation that I have included this very interesting spider 

 in the genus Trochosa. It is probable that future collectors will discover other species 

 presenting similar special peculiarities in the position of the eyes, joined to the rather short, 

 but strong, unattenuated legs of the present spider ; in which case it might become necessary 

 to form a separate genus, or ub-genus, for their reception. 



The cephalothorax is oval, broad, and truncate at its fore extremity ; the marginal 

 lateral constrictions of the caput are slight, and the height of the clypeus is at least equal to, 

 or even exceeds, double the diameter of one of the central eyes of the front row. Its colour 

 is yellowish, with a narrow marginal band, and two broad longitudinal lateral bands, of a 

 rusty red-brown hue, leaving a rather indistinct, median, tapering, yellowish band strongly 

 constricted near the occiput, and having a large part of its surface along the middle line 

 suffused with rusty red-brown, and containing towards its hinder extremity the thoracic 

 indentation, which is marked by a fine, deep red-brown line : the middle of each side is 

 occupied by a longitudinal, well-defined, but not very broad, yellow band. The fore part of 

 the area enclosed by the middle and posterior rows of eyes is of a dark reddish-brown colour ; 

 the hinder part of this patch contains two oval, parallel, yellowish markings. Sometimes 

 the slender red-brown lines defining the outer sides of these oval markings are obsolete, 

 leaving a short, dark red-brown stripe, ending a little way behind the posterior row of eyes, 

 its termination, more or less, laterally dilated. The broad lateral rusty-brown bands are 

 traversed by numerous deep red-brown lines, all radiating or converging to the thoracic 

 indentation. The surface of the cephalothorax is covered with yellow-grey pubescence, and 

 there are numerous blackish bristles on the upper part and sides of the caput. 



The eyes are in the usual three rows 4, 2, 2 ; the central pair of the first row are larger 

 than the laterals, and are divided by an interval exceeding a diameter, and each is very near, 

 but not quite contiguous, to the lateral on its side ; the front row is very slightly, if any- 

 thing, shorter than the second ; the eyes of the second row are, if anything, slightly smaller 

 than those of the third row, those of both the second and third rows .being very considerably
