88 SECOND YARKAND MISSION. 



with darker brown ; on the hinder half is a median longitudinal series of strongish, but not 

 very conspicuous, yellowish-red, angular bars or chevrons. The under side is dark, of a 

 rather sooty-brown hue ; the form of the genital aperture is distinct and characteristic ; the 

 hairy clothing of the abdomen had been entirely denuded. 



Hab. On the road across the Pamir from Sirikol to Panja and back, between April 22nd 

 and May 7th, 1874. 



Genus LYCOSA, Latr. ad partem LYCOSA, Thor. 



110. LYCOSA CONDOLENS, sp. n. 



Adult male : length 2f lines. 



The general form and appearance of this spider are like those of Lycosa agricola, Thor. 

 and some other closely-allied European species. The cephalotlwrax is deep brown, in some 

 cases approaching to black, with a narrow median, and, on each side, a submarginal brownish- 

 yellow stripe ; the median stripe is often very indistinct, and seldom runs (towards the eyes) 

 beyond the occipital region, certainly not reaching nearly to the ocular area, and the marginal 

 stripes are irregular, or somewhat dentated, on their edges. These stripes are clothed with 

 pale hairs. The ocular area is black, and the clypeus, which rather exceeds in height the 

 diameter of one of the fore-central eyes, is yellow. 



The eyes are in the ordinary position ; the foremost row is distinctly shorter than the 

 middle one, and its eyes are very small ; those of the central pair being scarcely larger than 

 the laterals, and the interval between them is double that between each and the lateral eye 

 on its side. The eyes of the middle row are considerably farther apart than a diameter's 

 interval, in fact, nearly equalling two diameters ; being equal to the interval between each 

 and the lower margin of the clypeus at its nearest point. The hinder row is longer than the 

 middle one, and its eyes are smaller than those of that row. 



The legs are long, rather attenuated, furnished with hairs, bristles, and spines ; they are 

 of a brownish-yellow colour, the femora and tibiae annulated and marked with black-brown 

 and yellow-brown ; the femora are often more or less completely suffused with black-brown. 

 This is only, however, the case with some adult males, and is probably owing to their having 

 been longer in the adult state; the legs of the fourth pair are the longest, and those of the 

 third pair slightly the shortest. 



The palpi are moderately long ; the humeral joint is nearly black, the cubital and radial 

 joints yellow ; the latter is the longest, and black on the whole (more or less) of the under 

 side ; the upper side is furnished with white hairs, mostly close to the fore extremity ; the 

 digital joint is of tolerable size, round, oval, and black behind, pointed and of a paler brown- 

 ish hue in front. The palpal organs are characteristic in their structure, though they do 

 not present anything very remarkable in form ; there is, about their middle, a not very 

 prominent, somewhat crescent-shaped, process, one of whose limbs is truncated, and the 

 other, the shorter, is blunt-pointed. 



The maxillae, are dark reddish brown, yellowish at their fore extremities. 

 The labium is also of a similar colour, yellowish at the apex. 



The falces are moderately long, not particularly strong, straight, perpendicular, of a 

 brownish-yellow colour, more or less clouded with deep brown. 

 The sternum is oval and nearly black.
