Ijcngth of tlic female 4th of an inch ; length of the cephalo- 

 thorax jxyth, breadth y^j^th ; breadth of the abdomen y'jth ; 

 length of a posterior leg y%ths; length of a leg of the third

The cephalothorax is oval, glossy, thinly clothed with hairs, 

 which are most abundant in the medial line, pointed before, de- 

 pressed at the base and on the sides, which are marked with 

 furrows converging towards the middle ; its colour is yellowish- 

 brown, with a broad dark-brown baud extending along each 

 side, whose exterior border presents an irregular outline, and a 

 narrower one of the same hue on each lateral margin ; the frontal 

 margin, from which some long hairs are directed forwards, has 

 a red-brown tint. The eyes are seated on black spots on the 

 anterior part of the cephalothorax ; the intermediate eyes of the 

 greatly curved posterior row are the largest of the eight, and the 

 intermediate ones of the anterior row are larger than the lateral 

 eyes of the same row. The falces are small, conical, armed with 

 a few minute teeth on the inner surface, and of a yellowish-brown 

 colour, with a dark-brown streak in front, which is palest in the 

 medial line. The maxillffi are short, strong, convex on the under 

 side, rounded at the extremity, and somewhat inclined tov.ai-ds 

 the lip ; the sternum is broad and heart-shaped. These parts 

 have a yellowish-brown hue, the sternxmi having dark-brown 

 spots on its lateral margins and posterior extremity. The lip is 

 small, triangular, but truncated at the apex, and of a dark-brown 

 colour, the apex having a tinge of yellow. The legs are loner, 

 robust, and provided with hairs and strong ?pines, two parallel 

 rows of the latter occurring on the inferior surface of the tibiie 

 and metatarsi of the first and second pairs ; the femora and tarsi 

 have a yellowish-brown hue, that of the genua, tibise, and meta- 

 tarsi being dark brown ; the fourth pair is the longest, then the 

 first, and the third pair is the shortest ; each tarsus is terminated 

 by two curved, minutely pectinated claws, below vxhich there is 

 a small scopula. The palpi are of a yellowish-brown colour, and 

 have a small, curved, slightly pectinated claw at their extremity. 

 The abdomen is oviform, haiiy, convex above, and projects over 

 the base of the cephalothorax; it is of a yellowish-brown colour,
