The legs are long, slender, provided with hairs and sessile spines, and of a red-brown 
hue, marked with brownish annuli; the first pair is the longest, then the fourth, and the third 
pair is the shortest; each tarsus is terminated by three claws ; the two superior ones are 
curved and deeply pectinated, and the inferior one is inflected near its base, on each side of 
which there are two small teeth. The palpi resemble the legs in colour, and have a curved, 
pectinated claw at their extremity. The cephalo-thorax is compressed before, convex in the 
cephalic region, and rounded on the sides, which are depressed and marked with furrows 
converging towards an oblong indentation in the middle ; it is covered with yellowish-brown 
hairs, and is of a pale, reddish-brown colour, the anterior part being the darkest; on each 
lateral margin there is an irregular, longitudinal, brownish-black band, and another of the
