specimen of 3 lines long, 1| lines ; breadth of cephalothorax rather 

 over 1 line. 



Adult male. Length If lines. 



The sexes are very dissimilar in appearance. In the female the 

 cephalothorax is oblong, caput very large, hinder slope abrupt, 

 upper surface moderately convex ; the ocular area occupies at least 

 one third of the whole length of the cephalothorax, and the height 

 of the clypeus is scarcely equal to tlie length of the area of the four 

 central eyes. The colour is yellow-brown, vrith a broad dark brown 

 longitudinal band on eacli side. The whole is clothed with coarsish 

 grey hairs, showing most conspicuously on the lateral margins, on 

 the central space between the dark lateral bands, being especially 

 long and conspicuous at the thoracic junction, and forming some 

 white lines connecting the eyes and bisecting the area of the four 

 central ones. 



The eyes form a very large quadrangle, whose posterior side is the 

 shortest and its anterior much the longest. They are small, the 

 posterior eyes of the central group largest, the rest apparently 

 nearly equal. Those of the central group are close together at the 

 fore extremity of the quadrangle, but not contiguous, forming a 

 small square or trapezoid, whose anterior side is shorter than the 

 posterior. The interval between the eyes of these two sides respec- 

 tively is L;reater than a diameter, while the interval between each 

 anterior and the posterior eye next to it is less than the diameter of 

 an anterior eye. 



The legs are strong and of moderate length, 1,4,2, 3, of a yellow- 

 brown colour; the femora, as well as the tibiae of the first and 

 second pairs, nearly black ; in some examples the legs have a some- 

 what animlose appearance. They are almost entirely destitute of 

 spines, but thickly clothed with hairs, of which many are grey, 

 giving them a hoary look. The tibiae of the first two pairs are rather 

 stouter than the rest, and the metatarsi of the first pair, in old 

 females, are of a brightish red hue, those of the second pair less so. 

 Towards the inner side of the metatarsi of the fourth pair is a 

 calamistrum running the whole length of the joint, but much 

 concealed by the other hairs. 



Falces strong, of moderate length, vertical, subconical, darker in 

 colour than the cephalothorax, and clothed with grey hairs, a band 

 across the base in front being more dense and conspicuously white. 

 The fangs are bright red-brown, but rather weak. 



The maxilla, labium, and sler?ium are deep brown, clothed with 

 grey hairs, and of normal form. 



The abdomen is oval, a httle broader in some examples behind 

 than in front ; its general colour is more or less bright warm yellow- 

 brown, clothed with grey and other hairs ; on the upperside are 

 three longitudinal, more or less well-defined dark brown stripes, of 

 which the central one is the narrowest and least conspicuous, and the 

 lateral ones are often dentated posteriorly. The lateral margins and 

 sides also are dark black-brown, and on the underside are two 

 conspicuous reddish-yellow-brown patches, placed transversely and
