 of the cephalothorax, and has some loni;, prominent black 

 hairs in front ; it is cK)thed with short adpressed hairs, and is 

 of a dull-bhick hue ; a transverse white band occurs at the 

 anterior extremity of the upper ])art, from each end of which 

 a short line of the same hue is directed backwards ; in the 

 posterior region a white band surrounds a black space, which 

 comprises a few rather ol)scure, an;j;ular white lim^s that have 

 their vertices dirccte(l forwards; the spinners are black, pro- 

 minent, and cylindrical, the inferior pair being the longest 

 and most robust ; the under part is of a dull-greyish colour in 

 the middle, the branchial opcrcula have a yellow hue, and the 

 colour of the vulva, which is somewhat crescent-shaped, is 

 black sliglitly tinged with red. 



Immature males that have to undergo their final eedysis 

 resemble the adult female in colour, but the white bauds and 

 lines are not so distinctly marked.
