greater than an eye's diameter. The height of the clypeus is 

 no more than equal to the diameter of one of the fore-central 

 eyes. 



The legs are tolerably long, 1, 4, 2, 3, and armed with spines 

 of no great strength, the strongest being those underneath 

 the tibise of the first and second pairs ; they are of a brownish 

 yellow colour, the tibia3 tarsi and metatarsi of the third and 

 fourth pairs distinctly, those of the first and second pairs in- 

 distinctly, annulated with deep reddish brown. The femora 

 and genual joints are strongly suffused with a similar hue 

 towards their fore extremities. 



The palpi are tolerably long, and similar in colour and 

 markings to the legs. 



The falces are long, powerful, rather directed backwards, 

 and convexly prominent towards their base in front. They 

 are of a deep, rich, red-brown hue, and furnished with bristly 

 hairs. 



The maxillm and labium are of normal form, of a dark red- 

 brown colour tipped with yellow. 



The sternum is heart shaped, similar to the falces in colour, 

 and has strongish prominences on its surface round the 

 margin, opposite to the insertions of the legs. 



Abdomen large, broad-oval, projecting considerably over the 

 cephalothorax, and extending forwards beyond the thoracic 

 indentation. It is thinly clothed with hairs ; the general 

 hue is yellowish, mottled with red brown ; two longitudinal 

 strongly angulated black bars, one on each side near the 

 outer margin, strongly edged on. their outer sides, and in 

 some parts also on their inner sides, with cream colour, 

 enclose the greater part of the upper surface. The posterior 

 half of the enclosed area is more or less covered with black 

 patches and mottlings, and at its anterior extremity is an 

 oblong, deep, blackish-brown patch, with two small prominent 

 points on each side, and margined exteriorly with cream 

 colour ; the sides and under side are marked and suffused 

 with brownish black. From the anterior side of the genital 

 aperture a short, deep, red-brown epigyne is directed back- 

 wards close to the inferior surface of the abdomen.
