286 REV. O. P. CAMBRIDGE ON THE [Feb. 20, 



(chiefly on the sides and margins) some granulations or small pointed 

 black tubercles, which give its surface a roughened appearance. 



The eyes are in two transverse rows, of which the fore one is 

 shortest and curved, the hinder one being straight ; the hind cen- 

 trals are rather nearer together than each is to the hind lateral 

 on its side, and the fore centrals are further from each other than 

 each is from the fore lateral on its side ; the four central eyes 

 form a square, whose hinder side is shortest, and those of each late- 

 ral pair are contiguous and placed obliquely : the clypeus is high, 

 transversely impressed below the eyes, and prominent above the 

 falces. 



The legs are moderately long and strong, their relative length 

 1, 4, 2, 3 ; they are of a yellow colour, and the femora are furnished 

 with numerous small, black, pointed denticulatious ; the terminal 

 tarsal claws are three in number. 



The palpi are not very long, but slender, and of a dull greenish- 

 olive hue ; the cubital joint is prominent, in a somewhat angular 

 form above, towards its fore extremity ; the radial is very small at 

 its junction with the cubital, but broad and spreading at its fore 

 extremity; the digital is of a longish-oval form, with a somewhat 

 pointed lobe near its fore extremity, making it bifid at that part : 

 the palpal organs are well developed and rather complex ; they have 

 several prominent corneous and spiny processes, oue of a semi- 

 diaphanous nature at their extremity. The fa fees are moderately 

 long and vertical, but rather slender and weak. The sternum is 

 thickly marked with small punctures, and is of rather a darker 

 colour than the cephalothorax. 



The abdomen is short-oval in form, and very convex above, being 

 almost globular in the male, but less so in the female. The male 

 has a kind of corneous socket beneath the fore part, into which the 

 binder extremity of the cephalothorax fits, as in the last species 

 described ; it is a deep rich red chocolate-brown colour, and (in the 

 male) has four large circular shallow impressions on the centre of its 

 upperside, somewhat resembling those on the abdomen of Gastera- 

 cantha ; the upperside is also marked very conspicuously with 

 cream-white spots and bands, forming with the ground-colour a 

 pattern which may be described as a longitudinal series of four to 

 five pairs of markings, occupying the whole upperside ; the yellow 

 bars and lines are often more or less obliterated or interrupted, and 

 then form simply three nearly parallel longitudinal broken bars, 

 with traces of some short transverse ones ; a more or less continuous 

 bar or line of cream-white runs completely round the sides, and 

 divides the upper from the underside ; and in front of the genital 

 opening is a small spot of the same colour. 



Adult and immature examples of both sexes of this very pretty 

 and distinct Spider were found in numerous localities throughout 

 Palestine, and always beneath stones. The abdomen of the female is 

 destitute both of the four large circular impressions on the upper- 

 side and of the socket beneath the fore margin.
