the middle of the posterior part. Mandibles subconical, vertical, 

 hairy in front, brown, with two black spots near the base of each. 

 Maxillse gibbous near the base, on the under side, somewhat 

 pointed at the extremity, inclined towards the lip, of a yellowish 

 brown colour. Lip triangular, rounded at the apex, dark brown. 

 Sternum heart-shaped, pale yellowish brown. Legs long, pro- 

 vided with hairs and sessile spines ; they are of a yellowish brown 

 colour spotted with brownish black, particularly on the upper 

 side ; second pair the longest, then the first, which a little ex- 

 ceeds the third, fourth pair rather the shortest. Each tarsus is 

 terminated by two curved, pectinated claws, and is provided with 

 a climbing apparatus. The palpi resemble the legs in colour. 

 Abdomen broader in the posterior than in the anterior region, 

 but pointed at the spinners ; it is thickly covered with hairs, and 

 its anterior extremity, which projects a little over the base of the 

 cephalo-thorax, is notched in the middle ; the upper part is yel- 

 lowish gray, with a longitudinal dark brown band, which has an 

 angular projection on each side, near the middle, extending from 

 the anterior extremity about half-way towards the spinners ; to 

 this band succeeds two distinct, parallel series of oblique bars of 

 the same hue, which diminish in extent as they approach the 

 spinners, and are enlarged and confluent at the extremities ; and 

 the whole is encompassed by a brownish black band which does 

 not quite extend to the spinners ; four dark brown depressions, 

 situated on the sides of the anterior, medial, dark brown band, 

 two contiguous to its lateral, angular projections, and the other 

 two, which are the largest, near its posterior extremity, form a 

 trapezoid whose shortest side is before ; sides and under part yel- 

 lowish gray, the former being minutely spotted with dark brown. 

 Sexual organs conspicuous, reddish brown. Plates of the spira- 

 cles yellow. The body and limbs are supplied with compound, 

 sessile hairs.

Eyes disposed on the anterior part of the cephalo-thorax in 

 two curved transverse rows, forming a crescent, whose convexity 

 is directed forwards ; the lateral eyes of the posterior row, which 

 are seated on small tubercles, are rather the largest, and the in- 

 termediate eyes of the same row are rather the smallest of the 

 eight. Cephalo-thorax nearly circular, but compressed before, 

 truncated in front, and abruptly sloping behind; it is convex, 

 thinly covered with yellowish gray hairs, and has a broad yel- 

 lowish brown band extending along the middle; the sides are 

 brown, with a fine, longitudinal, whitish line on the lateral mar-
