length of a posterior leg i ; length of a leg of the third 

 pair a-. 



The cephalothorax is long, glossy, sparingly clothed -with 

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

 on the sides, which are depressed and marked with furrr \vs 

 converging towards a naiTOw, slight indentation in the median 

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

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

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

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

 black line, and two sliort, parallel, obscure, brown lines occiir 

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

 tical ; the maxilla3 increase in breadth from the base to the 

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

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

 pale-yellowish hue, the maxilla} being the palest, and the 

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

 convex, sparingly sup])lied with hairs, and of a didl-yellow 

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

 posterior extremity, where they form a somewhat bifid 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 witli 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 j^air 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 pal])i are long, of a pale-yeHowish 

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

 The abdomen is oviform, convex above, jiroji'cts over tlie base 

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

 pix'ssed pale hairs ; the colour of the uj^per part and sides is 

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

 of the former moi-e 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 i'roux 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 tliat of the coccyx 

 and spinners is yellowish-white. 



The immature fi'male described above wa- tlie only speci- 

 men of this Lijcosa comprised in the collection.
