The length of the male is 2J lines, and that of the female 3J 

 lines. 



The cephalo-thorax is short and broad. The colour of that of 

 the male is reddish yellow-brown ; the central longitudinal band 

 is bordered on each side by a broadish, deop, red-brown, stripo ; 

 and the lateral margins have a similar, though rather paler, 

 stripe. The central marking, behind the eyes, is defined by a 

 narrow, but clear, whitish-j'ollow, marginal lino ; the form of 

 its pointed posterior extremity is curvi-linear, and it is sometimes 

 divided longitudinally by a red-brown lino.

 of a deep blackish, red-brown colour ; the tibice, metatarsi, and 

 tarsi, as well as the whole of tho third and fourth pairs being of 

 a reddish-yellow hue ; the femora of all four pairs are usually 

 marked underneath with a longitudinal yellowish line. The 

 spines are tolerably long, numerous, and rather strong.

 colour, tingod with red, the humoral joint being tho darkest- 

 The radial joint has a pointed apophysis at its oxtremity on tho 

 outer side, and another prominent ono beneath. Tho digital 

 joint is round-oval, pointed in front, and of tolerable size. The 

 palpal organs are not very complox, but have one or two strong, 

 prominont processes near their base.
