ochreous at the base, pale grey on tips, and dotted there with 
black. Head and anterior part of body to about the second 
pair of legs rather pale rust-colour, irrorated with black ; 
there is in some specimens an ochreous marking on the 
dorsal median line of the head. Rest of body dark slaty- 
grey, irregularly spotted with small sub-circular rust-coloured 
spots, most. of them centred with a black dot (the spots are

the inside concolourous with the underside; on the outside

the legs are pale ochreous. Between each pair of legs, on
