Ahdomen of a somewhat elongate-oval shape (m some species 

 humped near the middle), and clothed with hairs, of which some 

 form small tufts variously disposed.

The male measures 1 J lines in length, and the female about 

 2£ lines. 



The cephalo-thorax is clothed with short grey hairs, and 

 striped longitudinally and alternately with blackish-brown and 

 brownish-yellow, the central stripe being narrow and of the 

 latter colour. 



The legs are brownish-yellow, marked and annulated with 

 dark yellowish-brown ; they are olothed with fine hairs, and 

 besides the calamistra on the upper side of the metatarsi of the 

 fourth pair, there are beneath the tarsi, and the hinder extremity 

 of the metatarsi, numerous short, regularly disposed spines. 



The abdomen is of an oblong-oval form, and has its fore part, 

 and the hinder part of each side clothed with white hairs ; the 

 upper side is of a dull, yellowish-white colour, marked with 

 threo longitudinal, dark-brown lines. The sides are marked 

 with several more or less distinct, and very oblique, blackish- 

 brown stripes. The under side is black-brown with irregular, 

 yellowish, lateral margins. The spinners of the inferior pair, 

 are stronger, but rather shorter than tho superior ones, the 

 latter being two-jointed. On the upper part of the abdomen 

 are some small tufts of white hairs, but these are very easily 

 rubbed off, so that in some examples they are absent even before 

 capture.
