Upper part of the cephalo-thorax convex, glossy, thinly covered with hairs, 

 broadly truncated before, with a narrow indentation in the medial line of 

 the posterior region ; its colour is dark brown, the anterior part and 

 margins being much the darkest. Mandibles powerful, conical, convex 

 at the base, in front rather prominent, armed with a few teeth on the 

 inner surface, and of a very dark brown colour, approaching to black. 

 Lip somewhat oval, truncated at the extremity, resembling the mandibles 

 in colour. Maxillae long, straight, enlarged where the palpi are inserted, 

 and at the extremity, which is rounded. Sternum oval, glossy, with small 

 eminences on the sides, opposite to the articulation of the legs ; its colour, 

 and that of the maxillae, is dark reddish brown. Eyes disposed in two 

 transverse, parallel rows on the fore-part of the cephalo-thorax ; the ante- 

 rior row, which is the shorter, is situated just above the frontal margin ; 

 the intermediate eyes form a trapezoid whose anterior side is the shortest, 

 those of the anterior row being the largest of the eight. Legs short, of a 

 pale dull yellowish hue ; fourth pair the longest, then the second, third 

 pair rather shorter than the first. Each tarsus is terminated by two 

 curved, pectinated claws, below which is a small brush or climbing appa- 

 ratus. Palpi short, with a small curved claw at their extremity ; they 

 resemble the legs in colour. Abdomen oviform, hairy, slightly depressed, 

 projecting over the base of the cephalo-thorax ; it is of a dark reddish 

 brown hue, the medial line of the anterior half of the upper side being the 

 darkest. Spinners prominent, very dark brown. Plates of the spiracles 

 pale red-brown. 



The male resembles the female in colour and in the relative length of 

 its legs, but it is smaller than she is. Third and fourth joints of the palpi
