thorax is rather short-oval, constricted laterally at the caput, the 

 fore part of which is rather narrow ; its colour is dark brown, a 

 broad central band comprising nearly the whole of the caput, but 

 gradually narrowing to the hinder part of the thoracic portion, as 

 well as a broad band on each side above the lateral margins, being 

 thickly clothed with short white hairs. Looked at in profile, the 

 hinder slope of the cephalothorax is abrupt, and from its summit 

 there is a gradual and even slope to the eyes. 



The eyes are of moderate size, in two almost equally curved trans- 

 verse rows (the front row being a little the shortest), the curves 

 directed away from each other, and forming a broadish transverse 

 oval area ; the eyes of the hind central pair are rather further from 

 each other than each is from the hind lateral on its side, being 

 separated by about an eye's diameter ; and the same relative posi- 

 tion holds good in regard to the eyes of the front row ; those of 

 each lateral pair are placed very slightly obliquely, but are not quite 

 contiguous to each other ; the four central eyes form a quadrangular 

 figure, whose length is greater than its breadth. 



The legs are moderately long and strong, furnished with hairs and 

 spines; their relative length is 4, 1, 3, 2, the difference between 1 

 and 3 being very slight indeed ; the colour of the first and second 

 pairs is yellow, that of the third and fourth pairs is deep brown, 

 sparingly banded with dull yellowish, the bands clothed with short 

 white hairs ; the tarsi are dull yellowish brown, and each terminates, 

 as far as could be ascertained, with two claws, beneath which is a 

 black scopula. 



The palpi are not very long, moderately strong, and of a yellow 

 colour, similar to that of the fore legs. The cubital and radial joints 

 are short but of equal length ; the latter is the strongest, and has a 

 narrow, angular prominence on its underside, the upper side being 

 furnished with bristles, hairs, and spines ; the digital joint is large, 

 oval, with its fore extremity produced into a rather fine point. The 

 palpal organs are simple, consisting of a large roundish lobe, marked 

 on its surface with sinuous dark lines, and produced in a tapering 

 form at its fore extremity, where they terminate in a spiny-looking 

 reddish-brown point immediately beneath the extremity of the 

 digital joint. 



The falces are moderately long, not very strong, nearly vertical, 

 and of a dark yellow-brown colour. 



The maxillce are short and oblong in form, of a yellow-brown 

 colour, and pale yellowish at the extremities. 



The labium is very short, rounded at its apex, which is of a pale 

 yellowish hue, the rest being darker. 



The sternum is oval heart-shaped, of a deep yellow-brown colour, 

 sparingly clothed with short whitish hairs. 



The abdomen is oval, narrower before than towards its hinder 

 part ; the upper part and sides are dull black ; on either side of the 

 upper part is a bold longitudinal, somewhat zigzag, broken pattern 

 along its whole length, densely clothed with short white hairs ; the 

 lower portion of the sides is also clothed with white hairs ; the
