length of a posterior leg ^] length of a leg of the third 

 pair^. 



The cephalothorax is long, glossy, sparingly clothed with 

 short hairs, compressed before, truncated in front, and rounded 

 on the sides, which are depressed and marked with furrows 

 converging towards a narrow, slight indentation in the median 

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

 the cephalic region, where the eyes are situated, being black ; 

 a broad, irregular, brown band, mingled with yellowish-brown, 

 extends along each side, the lateral margins have a brownish- 

 black hue, and two short, parallel, obscure, brown lines occur 

 immediately behind the eyes. The falces are conical and ver- 

 tical ; the maxiUse increase in breadth from the base to the 

 extremity, which is rounded, and are somewhat inclined to- 

 wards the lip, which is nearly quadrate. These parts have a 

 pale-yellowish hue, the maxillee being the palest, and the 

 base of the lip the darkest. The sternum is heart-shaped, 

 convex, sparingly supplied with hairs, and of a dull-yeUow 

 colour ; the lateral margins, which are jet-black, meet at its 

 posterior extremity, where they form a somewhat biiid spot. 

 The eyes resemble those of other species of the genus with 

 regard to their disposition and relative size, the dimensions of 

 the four small ones forming the anterior transverse row being 

 equal or nearly so. The legs are long, provided with hairs 

 and sessile spines, and are of a pale-yellowish hue, with 

 obscure soot-coloured annuli, which are most conspicuous on 

 their inferior surface ; the fourth pair is much longer than the 

 second, which rather surpasses the third (the anterior legs 

 were missing) ; each tarsus is terminated by three claws ; the 

 two superior ones are curved and pectinated, and the inferior 

 one is very minute. The palpi are long, of a pale-yellowish 

 hue, and have a small pectinated claw at their extremity. 

 The abdomen is oviform, convex above, projects over the base 

 of the cephalothorax, and is thinly clothed with short ad- 

 pressed pale hairs ; the colour of the upper part and sides is 

 black ; a red-brown band extends from the anterior extremity 

 of the former more than a third of its length along the middle, 

 and on each side of it there is a longitudinal line of the same 

 hue ; a row of red-brown spots passes from the extremity of 

 the median band to the coccyx, diminishing in size as they 

 approach the latter ; and on each side of this row there is an- 

 other of the same hue ; the sides are freckled with red-brown ; 

 the under part has a dull-yellow colour, and that of the coccyx 

 and spinners is yellowish-white. 



The immature female described above was the only speci- 

 men of this Lycosa comprised in the collection.
