82 SECOND YARKAND MISSION. 



yellow, with a dentated marginal band, and a broader lateral strongly dentated one, of a dark- 

 brown colour on each side, leaving a large central star-shaped, or radiated, brownish-yellow 

 marking. The ocular area is dark-brown, and the whole surface of the cephalothorax is 

 pretty thickly clothed with hairs, many among which are prominent, dark brown, and of 

 a bristly nature. 



The eyes are grouped as in T. picta. Those of the hinder row are smaller than those of 

 the middle row, but considerably larger than the central pair of the front row ; the eyes of 

 the middle and hinder rows form a quadrangular figure whose posterior side is not greatly 

 longer than the anterior one, the length of the sides being apparently equal to that of the 

 posterior side. The anterior row of eyes is, if anything, slightly shorter than the middle 

 row, and the interval between the eyes of its central pair is larger than that between each 

 and the lateral eye next to it, to which last it is very close, though not quite contiguous. 

 The height of the clypeus is at least equal to twice the diameter of one of the central eyes 

 of the front row. 



The legs are moderately long and tolerably strong, particularly the femoral joints ; they 

 are of a dark-yellowish colour with dark-brown annuli, and are thickly clothed with hairs and 

 long prominent slender bristles, those of the third and fourth pairs being armed with spines. 



The palpi are rather short, hairy, and similar in colour and markings to the legs. The 

 radial joint is a little shorter, but of equal strength with the cubital ; the digital joint is dark 

 brown at its base, paler at the extremity ; it is long and narrow, being only a little broader 

 at its basal part than the radial joint ; its length is equal to that of the radial and cubital 

 joints together; the palpal organs are small and simple, being very like those of T. picta. 



The falces are long, moderately strong, straight, perpendicular, and of a deep brown 

 colour. 



The maxillce and labium are of normal form ; their colour is yellowish-brown ; the 

 extremities of the former 'and the apex of the latter being of a paler hue. 



The sternum is oval, hairy, and of a dark yellow-brown colour. 



The abdomen is rather broader behind than in front ; it is hairy and of a brownish-yellow 

 colour ; the markings, which are of the general Lycosa type, and almost exactly similar to 

 those of T. picta, are delineated by dark blackish-brown lines and spots. The under side is 

 also more or less marked with the same. 



Hal. Yarkand and neighbourhood, November 1873 ; Yangihissar, April 1874 ; Yarkand, 

 between 21st and 27th May 1874 ; hills between Sirikol and Aktalla, between 8th and 18th 

 May 1874 ; route from Yarkand to Bursi, between May 28th and June 17th, 1874. 



102. TROCHOSA PBOPINQUA, sp. n. 



Adult female : length just over 5 lines. 



This spider is very closely allied to T. ruricola, De Geer, but is, I think, certainly of a 

 distinct species. 



The cephalothorax is broader behind and narrower before than in T. ruricola. The 

 broad, lateral, brown bands, instead of stopping behind the hinder row of eyes, run through 

 and include the laterals of both the middle and hinder rows. The median longitudinal yellow 

 band is similarly constricted at the occiput ; but is broader behind that point, and more radi- 

 ated than in T. ruricola ; and the two longitudinal brown stripes on the fore part of this 

 band are confluent with the sides of the brown lateral bands.
