paler towards the base than the legs are elsewhere. The colour both 

 of the legs and body varies considerably, from blackish brown to 

 yellowish or greyish brown ; the abdomen often has a few fine white 

 or greyish transversal lines on the hinder part of the back. The 

 posterior legs have usually fine, longitudinal, white lines along the 

 patella? and tibia? and occasionally also along the metatarsi. 



The male of this species is considerably smaller than the fe- 

 male and has brighter colours. The cephalothorax is black with a 

 fine white edge, and crossed by a row of white spots between the 

 eyes. The oral apparatus is blackish brown, the palpi mottled with 

 black and brown, the lamina black, brownish at the apex. The 

 legs are for the most part black above, and blackish brown on the 

 under side; the metatarsi and tarsi of the anterior legs are broadly 

 whitish towards the base, the tarsi of the 4:th pair almost entirely 

 greyish yellow, the posterior pairs, especially on the patella? and 

 tibia?, white-lined above. The abdomen above is black with 5 or 6 

 pure white transverse lines on the posterior half, the first of which 

 is broken in the middle. The anterior margin is occupied by an 

 i irregular broad transverse band of whitish colour. Moreover the ab- 

 domen exhibits a couple of small white spots behind that baud, and 

 several such spots on the sides. The tibial joint of the palpus is on 

 its outer side drawn out in the form of a broad, forward- and out- 

 ward-pointing lamina, which is lengthened by two divergent sharp 

 processes, or spines, one in the upper and one in the lower corner: 

 the upper one is slightly curved inward, directed forwards and a little 

 outwards and upwards, the lower is directed downwards, outwards 

 and forward; on the under side this joint also has a long, stout, 

 curved, first downward- and afterwards forward-directed, blunt pro- 

 cess, which is almost uniform in thickness, but slightly dilated 

 towards the apex. The under side of the bulbns has no projecting 

 processes. 



Of X. hifo I found some females and a male at Nice, and Mr 

 Simon has kindly sent me a female from Spain.
