LVII. — Descriptions of several Species of East-Indian Spiders 

 apparently new or little known to arachnologists. By John 

 Blackwall, F.L.S. 



A COLLECTION of spidcrs made at Meemt, Agra, and Delhi, by 

 Captain Francis Lyon, of the Royal Artillery, and obligingly 

 presented to me by his sister, Mrs. Greenall, of Stretton Par- 

 sonage, at the suggestion of my kind friend Miss Ellen Clayton, 

 comprised the following species : — 



Tribe Octonoculina. 



Family Lycosidje. 



Genus Lycosa, Latr. 



Lycosa Greenallice, n. sp. 



Length of an immature female -^ of an inch ; length of 

 the cephalothorax -£-^, breadth ^ ; breadth of the abdomen -p^j 

 length of a posterior leg-f^g-; length of a leg of the third pair -^. 



The eyes, which are unequal in size, are disposed in front 

 and on the sides of the anterior part of the cephalothorax; four, 

 much smaller than the rest, form a transverse row immediately 

 above the frontal margin, the two intermediate ones being de- 

 cidedly larger than the lateral ones of the same row; the other 

 four describe a trapezoid, the two anterior eyes, which are the 

 largest of the eight, forming its shortest side. The cephalo- 

 thorax is long, convex, sparingly clothed with hairs, compressed 

 before, rounded in front and on the sides, which are marked 

 with furrows converging towards a narrow indentation in the 

 medial line of the posterior region ; it is of a brownish-yellow 

 colour, with narrow, black lateral margins; the region of the 

 eyes has a brownish- black hue, and there are oblique rays on 

 the sides formed by rows of dark-coloured hairs. The falces are 

 long, powerful, conical, vertical, armed with teeth on the inner 

 surface, and have a red-brown hue. The maxillae are straight, 

 and increase in breadth from the base to the extremity, which 

 is rounded ; the lip is quadrate, and somewhat hollowed at its 

 apex ; and the sternum is oval. These parts are of a dull- 

 yellow colour, the base of the lip is tinged with brown, and the 

 sternum has a black band extending along the middle, which is 

 somewhat constricted at a moderate distance from its pointed 

 extremity. The legs are provided with hairs and sessile spines, 

 and have a dull-yellow hue, with imperfect, faint, soot-colourcd 

 annuli on the femora and tibise ; the fourth pair is the longest, 

 then the first, and the third pair is the shortest ; each tarsus is 

 terminated by three claws ; the two superior ones are curved 

 and pectinated, and the short inferior one is inflected near its
