92 SECOND YARKAND MISSION. 



Hab. Hills between Sirikol and Aktalla, 8th to 13th of May 1874 ; road from Yarkand 

 to Bursi, May 28th to June 17th, 1874. 



114. LTCOSA VINDEX, sp. n. 



Adult female : length 2J lines. 



This spider is very closely allied to Lycosa credula, but it is of a shorter, stouter form, 

 and the colours are of a generally duller hue. The median longitudinal yellow band on the 

 cephalothorax is broader, distinctly constricted at the occiput, and enlarged at the thoracic 

 indentation. The ocular area is black, with a geminated reddish-yellow spot between the 

 eyes of the hinder row ; the lateral brown bands are more distinctly traversed by darker lines 

 radiating towards the thoracic indentation. The clypeus is lower, not exceeding in height 

 two fore central eyes' diameter ; the legs are entirely annulated (though not very distinctly 

 excepting the tarsi), and they are also longer than those of L. credula. 



The sternum is very similar in its markings ; but the normal marking on the fore half of 

 the upper side of the abdomen is less distinctly marked, and is blunt-pointed at its hinder 

 extremity ; the usual angular bars which succeed it are longer, and, with the marking on the 

 fore part, are of a reddish yellow-brown hue ; this is also the prevailing tint of the upper side, 

 of which the rest is marked and striated with dark-brown ; the under side is of a dull- 

 yellowish hue, without any markings ; and the genital aperture is of a distinct and charac- 

 teristic form. 



Hab. Yarkand, November 1873. 



115. LTCOSA VINDICATA, sp. n. 



Adult female : length 2 lines. 



This spider is exceedingly closely allied to L. vindex, but I am induced to record it as a 

 distinct species, not only on account of its smaller size, but because the median longitudinal 

 yellowish band on the cephalothorax is narrower, and has no constriction at the occiput, nor 

 any lateral enlargement at the thoracic indentation ; the submarginal lateral brown stripe is 

 also more distinct and continuous, and the genital aperture differs a little in its form. In 

 most other respects it resembles L. vindex, though the legs are more distinctly annulated. 

 Its smaller size, shorter, stouter form, and reddish-brown hue of the paler markings on the 

 abdomen, as well as the far more distinctly and completely annulated legs, and lower clypeus 

 distinguish it readily from L. credula. 



Hab. Murree, June llth to July 14th, 1873, and between Yangihissar and Sirikol, 

 March 1874. 



116. LTCOSA PASSIBILIS, sp. n. 



Adult male : slightly over 3 lines. 



The cephalothorax is of a deep brown colour, with a broadish longitudinal median band, 

 and two lateral, narrower, sub-marginal ones slightly paler, and clothed with greyish hairs, 

 with which, indeed, the rest of the cephalothorax is, though more thinly, covered.
