Sallicus sublestus, \\. sp. 



Length of the female ^ of an inch ; length of the cephalo- 

 thorax -^, breadth -^V ; breadth of the abdomen ^V ; length of 

 a posterior leg -^-V ; length of a leg of the second pair -yV- 



The cej)halothorax is rather long, glossy, and somewhat 

 quadrilateral; it slopes abruptly at the base, projects a little 

 beyond the falces in front, and is of a dark-brown colour, the 

 cephalic region being the darkest. The minute intermediate 

 eye of each lateral row is nearly equidistant from the eyes con- 

 stituting its extremities. The falces are short, subconical, and 

 vertical ; and the maxillae are straight, and enlarged and 

 rounded at the extremity. These organs have a brownish-yellow 

 hue, the former having a tinge of red. The lip and sternum 

 are oval, and of a dark-brown colour. The legs are robust, 

 particularly those of the first and second pairs, and are of a 

 brownish-yellow hue ; they are provided with hairs and sessile 

 spines, two parallel rows of the latter occurring on the inferior 

 surface of the tibije and metatarsi of the first and second pairs ; 

 the fourth pair is the longest, then the third, and the second 

 pair is rather shorter than the first ; each tarsus is terminated 

 by two slender, curved claws, and below them there is a small 

 scopula. The palpi are short, and resemble the legs in colour. 

 The abdomen is oviform, glossy, convex above, and projects a 

 little over the base of the cephalothorax ; it is of a brown hue, 

 with two nearly parallel, short, white streaks at each extremity 

 of the upper part, the posterior ones being the broader ; there 

 are a few obscure, oblique, whitish streaks on each side of the 

 medial line, and two longer ones on the posterior half of each 

 side : the sexual organs are moderately developed, and of a red- 

 brown colour. 



The male is darker-coloured than the female, and the whitish 

 marks on its abdomen are less conspicuous. The legs have a 

 brown hue. The palpi are long and resemble the legs in colour; 

 the cubital and radial joints are clavate, and the latter, which is 

 rather the shorter, has a straight, pointed apophysis at its ex- 

 tremity, in front, towards the outer side, and a minute one on 

 the underside; the digital joint has an oblong-oval form; it is 

 convex and hairy above, compact at the extremity, with a con- 

 cavity underneath comprising the palpal organs, which arc well 

 developed, not very complex in structure, wdth a short, pale, 

 pointed process at their extremity, and are of a brown colour. 



This small Salticus inhabits the island of Madeira.
