1872.] SPIDERS OF PALESTINE AND SYRIA. 327 



The cephalothorox is of a deep shining hlack-brown colour, the 

 caput black ; it has a transverse stripe or band of white hairs imme- 

 diately behind the front row of eyes, also a marginal stripe and a 

 central longitudinal one of the same ; this last stripe commences in 

 a sharp angular point (in some examples this point is of a diamond- 

 shape, owing to a constriction just behind its fore extremity) between 

 the two eyes of the hinder row, and runs backwards beyond the 

 beginning of the hind slope. 



The legs are yellow, and are furnished with a few hairs and fine 

 spines, those of the fourth pair are the longest, and those of the 

 second pair the shortest ; each tarsus ends with a small black claw- 

 tuft. The falces are black-brown, moderately strong, rather long, 

 and a little projecting. The palpi are short and black ; the humeral 

 joint has a rather prominent and somewhat pointed enlargement 

 near its extremity on the inner side, very nearly approaching in the 

 structure of this joint to Spiders of the restricted genus Heliophanus 

 (Koch) ; the cubital is longer and stronger than the radial joint, and 

 has its outer extremity prolonged into a strongish blunt-pointed 

 apophysis ; the radial is short and of a peculiar form, being so short 

 as to have no linear dimensions on the outer side (which is sharp - 

 pointed), and rather obtusely produced on the inner side forwards ; 

 the palpal organs are highly developed and very prominent at their 

 hinder part, which projects backwards ; they have a small prominent 

 knob or protuberance on the hinder part of their lower surface. 

 The abdomen is black ; the upperside is divided from the lower by 

 a lateral marginal stripe on either side of bright white hairs ; and a 

 similar central stripe divides it longitudinally ; the former stripes 

 are interrupted, or, rather, formed by a series of short white oblique 

 lines or markings towards their hinder portions ; the underside is 

 dark brown, with two pale dull whitish and slightly curved longitu- 

 dinal stripes. 



The female resembles the male in the general character of the 

 markings ; but the central longitudinal white stripe on the abdomen 

 has some lateral angular points, or short incipient lines, on either 

 side of its hinder portion, in some examples resembling a series of 

 short confluent chevrons ; the lateral stripes also run round and 

 meet on the fore margin of the abdomen. Different examples of the 

 female vary in depth of colour. 



Both sexes of this pretty Salticus were found actively hopping 

 about among stones and short herbage on the plains of the Jordan. 



Salticus devorans, sp. nov. 



Male adult, length from 2\ to 3 lines. 



This species is nearly allied, both in form, structure, and co- 

 lours, to S 1 . paykullii (Sav.) and S. vaillantii (Luc), but may be 

 easily distinguished by its much smaller size and by differences in 

 the pattern formed by the distribution of its colour and markings. 

 The present species has no dark marginal border or baud on the 

 cephalothorax, while both the other species mentioned have it ; and 

 in those species also this marginal band branches upwards in a
