18/2.] SPIDERS OF PALESTINE AND SYRIA. 223 



presented no variation whatever in the uniformity and continuity of 

 the abdominal border. 



An immature male was found at Jerusalem under a piece of de- 

 tached rock in the valley of Hinnom, an immature female in a si- 

 milar situation near Ain Ata, and another at Tiberias. 



Fam. Dysderides. 

 Genus Segestria (Latr.). 

 Segestria perfida, Walck. Ins. Apt. i. p. 267. 

 An adult male at Jerusalem. 



Genus Ariadne (Savigny). 



Ariadne insidiatrix, Savigny, Arachn. d'Egypte, pi. 1. fig. 3. 



Immature females of this Spider were found in crevices of a bank 

 near Beirut. 



Genus Dysdera (Latr.). 



Dysdera westringii, sp. nov. (Plate XIII. fig. 2.) 



Male adult, length 4| lines ; female adult, 6 lines. 



In general form, colour, and appearance this species is very 

 similar to D. erythrina (Walck.) and D. rubicunda (Koch), but 

 from both it may be distinguished by the form of the palpal organs, 

 as well as by the surface of the cephalothorax and the sternum, 

 which are closely freckled with impressed dots or punctures. The 

 two foremost eyes are the largest of the six ; the falces are shorter 

 and less powerful than in the above-mentioned species ; and the 

 palpal organs are more attenuate, much constricted near the middle, 

 and are furnished at their extremity with a slender, curved, promi- 

 nent, black spine. The abdomen is similar in colour to that of 1). 

 erythrina, but (in spirit of wine) has a mottled or reticulate ap- 

 pearance. 



It is not uncommon throughout Palestine and Syria, and I met 

 with both sexes adult under stones in various places from Hebron 

 to Damascus. It is with great pleasure that I connect with this 

 Spider the name of M. Nicolas Westring, who has laboured long 

 and successfully in the working out of Swedish Spiders. 



Genus Oonops (Templeton). 

 Oonops punctatus, sp. nov. (Plate XIV. fig. 3a.) 



Male adult, length f of a line. 



The whole of this Spider is of a pale, but brightish, yellow-brown 

 colour, the legs being rather lighter than the rest. 



The cephalothorax is oval, pointed, but not constricted laterally 

 before ; it is glossy and very sparingly furnished with inconspicuous 

 hairs. 



The eyes (six in number) are large ; four, almost contiguous to
