margins of the sternum having a dark-brown hue. The legs 

 are long, and provided with hairs and spines, the tibial joint of 

 the second pair having numerous short, black, pointed spines on 

 its anterior surface ; the colour of the femora is pale yellow at 

 the base and dark brown at the extremity, the dark-brown hue 

 being most extensive on the anterior pair, and merely forming 

 an annulus on the third pair; the other joints of these limbs 

 have a brownish -yellow hue, and are marked with dark-brown 

 aunuli ; the first pair is the longest, then the second, and the 

 third pair is the shortest ; each tarsus is terminated by claws of 

 the usual number and structure. The palpi are short, and of a 

 pale-yellow colour, with the exception of the digital joint, which 

 has a brown hue; the cubital joint projects two long curved 

 hairs from its anterior extremity, in front; the radial is larger 

 than the cubital joint, prominent on its external and internal 

 surfaces, and supplied with long hairs ; the digital joint is oval, 

 with a glossy process at its base curved outwards ; it is convex 

 and hairy externally, concave within, and the palpal organs con- 

 nected with it are highly developed, prominent, with several 

 short, curved processes at their extremity, and are of a dark- 

 brown colour mingled with yellow. The convex sides of the 

 digital joints are directed downwards. The abdomen is oviform, 

 convex above, projecting over the base of the cephalothorax, and 

 is thinly clothed with long dark and light-coloured hairs; on 

 the upper part there is a large brownish-black, leaf-shaped mark, 

 which gradually decreases in breadth to the spinners, and whose 

 sinuous margins have an obscure, white, lateral border, forming 

 at its anterior extremity a conspicuous spot on each side of the 

 base of a triangular black spot situated at the anterior part of 

 the abdomen and having its vertex directed forwards; the leaf- 

 shaped mark comprises in the middle of its anterior part a fusi- 

 form mark faintly bordered with white ; the sides are of a 

 brownish-black colour mingled with dull white, and the brownish- 

 black under part has a curved yellowish -white line on each side, 

 whose posterior extremity is the palest and most conspicuous.
