Two females, one adult, the other immature, were found in cylin- 

 drical holes in a bank near Beirut ; the holes were lined with silk, 

 and their upper ends closed with a hinged lid similar to those of 

 Nemesia coementaria (Latr.). 



Fam. Filistatides. 

 Genus Filistata (Latr.). 

 Filistata attalica, Koch, Die Arachn. v. p. 6, pi. 146. fig. 343. 



Adult females in holes and crevices of trees and buildings at He- 

 bron and Damascus. 



Filistata albimaculata, sp. nov. (Plate XIII. fig. 1.) 



Male adult, length \\ to 2 lines. 



The cephalothorax is of an oblong-oval form, flattened above, and 

 very slightly constricted laterally at its fore extremity ; it is of a 

 yellow-brown colour, slightly tinged with red, and narrowly margined 

 with black-brown, the ocular region being suffused with black ; the 

 normal furrows and indentations are indicated by blackish-brown 

 lines ; and the whole is thinly clothed with coarse white and mostly 

 adpressed hairs. 



Eyes eight in number, considerably unequal in size, and grouped 

 closely together on a slight oval eminence ; they form two groups, 

 an outer and an inner one : the outer one is of four large eyes (two 

 on either side nearly contiguous to each other, the foremost of 

 each pair being the largest), forming a transverse oval ; the inner 

 group, also of four eyes, is much smaller, and forms a trapezoid 

 whose foremost side is shorter than the hinder one ; the two fore- 

 most of these eyes are smaller than the others, in fact the smallest 

 of the eight. Clypeus prominent. 



Falces small, prominent ; fang small. 



Legs rather long, strong; relative length 1, 2, 4, 3 ; they are of 

 a yellow-brown colour, slightly tinged with red ; the femora and 

 tibiae of the first and second pairs, and the femora of third and 

 fourth, are strongly suffused with black-brown ; the femora and tibiae 

 (jf the first pair are much stronger and longer than those of the 

 other legs. There are a few spines beneath the tibia? of the first 

 pair ; and all the legs are clothed with coarsish hairs, those on the 

 genual and metatarsal joints of the first pair being very conspicu- 

 ously white. There were, as far as I could ascertain, two terminal 

 tarsal claws. 



Pa/pi moderately loug and strong ; they spring at a considerable 

 distance from the base of the maxillae, and are similar to the legs in 

 colour ; the radial joint is long, strong, and tumid ; the digital short, 

 small, and difficult to distinguish separately from the base of the
